Mixing

How to Move Audio in Audacity Moving audio clips around the Audacity Timeline is an essential part of editing and creating a podcast. To get a finished product, you'll need to take all your recordings and bring them into the workspace to arrange them chronologically, apply transitions, and make additional edits. Audacity is a free audio editing software. It is very simple to use but has a lot of useful functions. If you have any questions or want a more detailed instructable about a specific funtion of Audacity please comment and I will help you the best I can. If you like this instructable please vote for it in the A/V contest. An audio file or recorded track needs to be present in order to start editing. See Audacity: Importing Audio Files and Audacity: Recording Audio for instructions. You can change the length of the audio preview before and after the cut on the Playback tab of Audacity Preferences. 'Play To Selection' shortcut: Press B to listen to part of the selection region, or to the audio before or after the selection. This helps you ensure the selection is exactly where you want it.

refers to the process of combining multiple Audacity tracks which play simultaneously into a single track.

Audacity mixes automatically when playing or exporting, but it can also physically mix selected multiple tracks together into one within the project. All selected tracks are mixed, regardless if the or buttons on any tracks are set to silence their playback.

The channel of a track being mixed affects whether it will be mixed into the left channel of the resulting track(s), the right channel, or both (mono). For example, if you have four tracks:

• Track 1: left channel
• Track 2: left channel
• Track 3: right channel
• Track 4: mono channel

and you select them all and perform a Mix and Render, you will end up with one stereo track: the left channel will contain a mix of tracks 1, 2, and 4 and the right channel will contain a mix of tracks 3 and 4.

Mixing

Mixing can be done for a number of reasons, for example mixing speech with background music to make a podcast, or adding different instruments into the same song. https://downlup540.weebly.com/slot-machine-strategies-to-win.html. Concatenating songs (for example, playing three songs one after the other) does not necessarily involve mixing, but if you wanted the songs to fade into each other it would involve mixing.

Within an Audacity project, you can physically mix selected multiple selected tracks into a single mono or stereo track using either of two explicit mix commands:

• Tracks > Mix > Mix and Render - which replaces the original track(s) with the mixed track
• Tracks > Mix > Mix and Render to New Track - which adds the mixed track to the project, preserving the original tracks.

By default, multiple stereo tracks are mixed down to a single stereo file on Export.

Also by default, multiple mono tracks are mixed down to a mono file, but if you pan any mono tracks to left or right or if there are any stereo tracks in the mix, the tracks are mixed to a stereo file. Note that the mono tracks are mixed to both the left and right channels of the resulting stereo file.

The Mixed and Rendered track will be placed where the bottom selected track was and given the name 'Mix'.

Unless, that is, a single selected track is rendered in which case it will retain its position, its track name and its properties (display type, waveform color)

Note that this may be useful in retaining membership of any Sync-Locked Track group to which the track(s) may have formerly belonged.

In Audacity, mixing is automatic. You could just put audio into two different tracks, play to listen to the result then export it as an audio file like MP3 or WAV or burn the WAV to Audio CD.

However once audio has been finally mixed (using Mix and Render or as in an audio file you might import into Audacity) it is essentially impossible to separate out all the original parts again; it's like trying to take the banana out of a banana milkshake after you've already put it through the blender. There are a few occasions when it actually is possible to separate sounds a bit - you can sometimes isolate the bass, or remove the lead vocals. But these processes do not always work well and usually cause some quality loss. So remember, as long as the multiple tracks are inside an Audacity project, you can manipulate them independently, but once you export as a mixed down file you cannot expect to separate the different parts again. So keep your Audacity project around if you plan to continue editing!

The controls used for mixing are the and buttons and the Gain (-..+) and Pan (L..R) sliders.

In the above example, mixing the mono (upper) and stereo (lower) track means that the audio of the mono track will be heard equally in both left and right channels of the resulting stereo mix.

Muting and Soloing

When working with multiple tracks, it's often important to be able to hear just one at a time. Each track has a Mute and a Solo button, allowing you to temporarily hear just some of your tracks.

• causes a track to be silenced. More than one track can be muted.
• can behave in two different ways depending on the setting made in Tracks Preferences.
  • Default behavior, the 'Simple' setting, is that clicking Solo on any track mutes all the other tracks. To solo more than one track, hold Shift down while clicking the button on the additional tracks to be soloed. On the additional tracks that are soloed, the Solo button overrides the Mute button.
  • Selecting 'Multi-track' setting will suit those used to mixing desks and other professional audio software. Any number of tracks can be made solo so that they mix together. If any Solo button is down this overrides the Mute button. If on any occasion you want the Solo button to play only one track at a time (so that clicking it releases any other Solo buttons), hold down Shift when clicking Solo.
• None: A third option in Tracks Preferences, the 'None' setting, removes the Solo button from all tracks, leaving just a Mute button which silences whichever track or tracks it is applied to. If on any occasion you want the Mute button to silence only one track at a time (so that clicking it releases any other Mute buttons), hold down Shift while clicking Mute.

You can press the and buttons while tracks are playing.

If you're using the keyboard, Shift+U toggles muting on the currently focused track which has the yellow border, and Shift + S toggles soloing. The solo shortcut works even if you hide the Solo button.

Sometimes it can be handy to export a preliminary mix with one or more of the tracks left out. Exporting will automatically ignore any tracks on which the button is pressed.

Gain and panning

Above the Mute / Solo buttons, each track has a - / + gain slider which adjusts the track's volume, and an L / R pan slider which adjusts the track's stereo position in the overall mix - whether it comes from the left speaker, right speaker or in-between. To change the value, just click on the slider and drag. For finer control when dragging, hold Shift while dragging or double-click on the slider or slider scale to enter a precise value as text.

The normal range of gain is from -36 dB to 36 dB. If you need more, choose Effect > Amplify. World edit minecraft install.

If you're using the keyboard, use:

• Alt + Shift + Up to increase the gain on the focused track or Alt + Shift + Down to reduce it
• Use Alt + Shift + Left to pan left on the focused track or Alt + Shift + Right to pan right.

Or press Shift + G to adjust the gain in a dialog box or Shift + P to adjust the pan.

Explicit Mixing and Rendering

While mixing is automatic on playback and export, there are times when you may want to explicitly tell Audacity to mix several tracks. This is useful in several ways:

• You can consolidate tracks which you have finished working on, making it easier to see the other tracks without scrolling up and down
• Playback may respond more quickly with fewer tracks
• You can see what the final mix will look like as a waveform so as to check the overall level of the final mix before exporting it.

To mix explicitly, select all the tracks you want to mix together then choose either Tracks > Mix > Mix and Render or Tracks > Mix > Mix and Render to New Track (shortcut Ctrl + Shift + M).

For mouse users, a quick way to select multiple tracks is to select the first track by clicking on its Track Control Panel, then hold Shift while clicking on the Track Control Panels of the other tracks you want to select.

Several things happen when you choose either of the Mix and Render commands:

• All selected tracks are mixed down to a single track called 'Mix'.
  • Except when Rendering just a single track, when it will retain its original track name.
• If you choose 'Mix and Render', the resulting track replaces the selected original track(s).
• If you choose 'Mix and Render to New Track', the original tracks are preserved so that the resulting track becomes an additional track in the project.
• The 'Mix' track is always placed in place of (Mix and Render) or underneath (Mix and Render to New Track) the bottom selected track.
• The new mixed track will be stereo unless the tracks you mixed were mono tracks panned to center.
• If any of the original tracks did not match the sample rate of the project (set at bottom left of the project window in Selection Toolbar), they will be resampled to match the project rate.
• Any envelope points defining amplitude modifications will be applied and the previous envelope points removed.
• Gain and panning changes will be applied and the sliders reset to normal in the mixed track.

You can always Edit > Undo if you're not happy with the results of Mix and Render, then make changes and try it again.

Mixing Levels

The act of mixing multiple tracks adds the waveforms together. In most cases this will cause the mixed track to have a higher peak and RMS (average) level than the individual pre-mixed tracks, though this is not always true by definition. How much (or whether) the peak level increases and how much louder it actually sounds depends on how related the waveforms of the mixed tracks are.

When peaks or troughs in the waveform coincide, the waveforms will reinforce each other, leading to an increased signal level. In fact if you combined two identical tracks, the signal level would exactly double, leading to an increase in peak level of 6 dB. But when a peak in one track coincides with a trough in another track the waveforms will tend to cancel each other out, leading to a lower level in the mix at that point.

Also the more tracks that have audio at the same point on the Timeline, the higher the mix level is likely to be.

The overall mix level is indicated on the Playback Meter when the project is playing. You can see individual meters for each track (showing the levels as modified by the track's gain/pan sliders and mute/solo buttons) if you enable View > Mixer Board.

Because mixing tracks is additive, the combined level may show clipping distortion in the Meter Toolbar. In that case, you should use the gain sliders on one or more tracks to reduce the overall level. If you already have the balance of the mix (the levels of the tracks relative to each other) exactly as you want it, select all the tracks using Ctrl + A then choose Effect > Amplify. Enter a negative value in the 'Amplification (dB)' box which will reduce the level of all the tracks by the specified value.

If you have just made a recording it is strongly recommended that you immediately export your audio using File > Export > Export Audio. to WAV or AIFF (ideally to an external drive) as a safety copy before you start editing the project.

Objective

The objective of this tutorial is to learn how to edit an audio file. To achieve this objective, we are going to import an existing sound file, remove all but 10 seconds of this file, apply a 1-second fade-out at the end, export the results, and play it in your favorite audio player. These steps will introduce the basic steps commonly used when editing the contents of an audio file.

Step 1: Find a file to edit

Audacity can import many common audio file formats, including WAV, AIFF, and MP3. If the optional FFmpeg library is installed, a larger range of formats, including WMA and the audio content of most video files, can be imported. Audacity cannot import copy-protected music files.

If you want to edit music that you have on an audio CD, you need to 'rip' the music into an audio file. See the Audio CDs page for information on getting the audio off of CDs and into Audacity.

Don't have any audio files handy? There is lots of free music online! Here is one site where you can download free music: Opsound

The recordings on this site are free, distributed under the Creative Commons Attribution-Sharealike license, which gives you the right to create a derivative work without paying royalties, as long as you give credit and make your derivative work free, too. This is similar to the license for Audacity, which allows any devloper to modify it and redistribute it for free.

Step 2: Import the file into Audacity

First launch Audacity, then import an audio file by selecting File > Import > Audio..

A quicker method is to just drag and drop the file as in the following examples:

Windows: Drag the audio file icon into the open Audacity window.

Mac: Drag the audio file icon to the Audacity icon in the Dock (does not work for all formats yet).

Linux: Drag the audio file icon into the open Audacity window.

All three platforms support:

• dragging the audio file into the Audacity window
• dragging the audio file to the Audacity icon on the Desktop.

Specific dragging behavior according to platform:

• On Windows and Mac you can also drag to Audacity's icon in a file manager application.
• On Mac and Linux you can drag the file to the Audacity icon in the Dock or Taskbar respectively to import the file into Audacity.
  • On Windows, dragging the file to the Audacity icon in the Taskbar will either switch the window to Audacity if it is running (from where you can drag the file in), or if Audacity is closed, give the option to launch Audacity with the file imported.

Command-line file importing: On all three platforms you can also import files by launching Audacity at the command-line and passing the files you wish to import as arguments. For example, on Linux Ubuntu:

[email protected]:~$ audacity Desktop/song.mp3 Desktop/speech.wav

imports the 'song.mp3' and 'speech.wav' files located on the Desktop in separate Audacity windows.

Step 3: Look at the waveform

This image above shows a stereo waveform. The left channel is displayed in the top half of the track and the right channel in the bottom half. Instalando ubuntu 18 04. The track name takes the name of the imported audio file ('No Town' in this example). Where the waveform reaches closer to the top and bottom of the track, the audio is louder (and vice versa).

The ruler above the waveform shows you the length of the audio in minutes and seconds.

Removing any DC offset (if present)

DC offset can occur in audio files so that the recorded waveform is not centered on the horizontal line at 0.0 amplitude. It can be caused by recording with a faulty audio interface. The example above is centered on 0 correctly and carries no DC offset. If your waveform is not centered, see the Normalize page for how to use Normalize to remove DC offset and how to check if your Windows sound device can perform this correction automatically.

Step 4: Listen to the imported audio

The image above shows Transport Toolbar.

Click the Play button to listen to the audio. Click the Stop button to stop playback. If you do not hear anything, see Audacity Setup and Configuration.

You can use the Space key on the keyboard as a shortcut for Play or Stop.

Click on Selection Tool then click on the waveform to choose a place to start, then click the Play button . Click and drag to create a selection, and then when you click Play button only the selection will play. Jw org library para descargar.

Keyboard use: You can select audio entirely using the left arrow, right arrow and other keys.

• Press Left or Right to move the cursor left or right respectively in the waveform.
• Hold down Shift while pressing Left or Right to create then extend a selection leftwards or rightwards respectively.
• Hold down Shift and Ctrl while pressing Left or Right to contract an existing selection leftwards or rightwards respectively.

Clicking the Skip to Start button or pressing the Home key will move the cursor to the beginning of the track. It's kind of like rewind, but it's not for playback - it will only work when playback is stopped.

Similarly, clicking the Skip to End button or pressing the End key will move the cursor to the end of the track.

To jump the playback position forwards or backwards from where it is now, click on the Timeline above the waveform at the point you wish to hear.

Keyboard use: You can use the following keys to skip around the audio file while listening.

• Press Left or , to move the playback cursor back one second.
• Press Right or . to move the playback cursor forward one second.
• Press Shift + Left or Shift + , to move the playback cursor back 15 seconds.
• Press Shift + Right or Shift + . to move the playback cursor forward 15 seconds.

The amount the cursor moves in this situation is called the 'seek time'. The long and short seek times (one second and 15 seconds in the examples above) can be set in the Seek Time When Playing section of Playback Preferences.

Step 5: Create a 10-second clip from your audio

You edit audio waveforms in Audacity in much the same way as you would edit text in a word-processing document. When you are editing text you first select the text you want to change and then choose what you want to do with it. You might want to cut or copy the text, delete it, paste new text in its place, or change it to bold. You do the same thing in Audacity: first zoom and select the range of audio you want to change, and then choose what you want to do with it.

The image above shows Edit Toolbar with the Zoom buttons highlighted. This is the Zoom In tool, and this is the Zoom Out tool.

To zoom in to get a closer look at the waveform, first choose the Selection Tool, then click near the point you're interested in, then click the Zoom In button. Keep clicking the Zoom In button until you see the detail you need. Note that when you click the Zoom In button the cursor is centered on the screen.

There are also menu commands and keyboard shortcuts for zooming. View > Zoom > Zoom In (or Ctrl + 1) is the same as clicking the Zoom In button. View > Zoom > Zoom Out (or Ctrl + 3) is the same as clicking the Zoom Out button. View > Track Size > Fit to Width (or Ctrl + F) will zoom the waveform so it fits in the window.

Use the Zoom commands so that you can make maximal use of your Audacity window to see as much detail as you need, or to make sure you see the entire file when necessary.

Walk through deleting all but approximately 10 seconds of selected audio

To cut this audio file down to exactly 10 seconds, use these following steps.

These steps require a mouse, except for using Space on the keyboard to play the selection and C to play either side of the selection. See below for how to create and adjust selections using the keyboard.

1. With playback stopped, click near the point where you want the 10-second piece to begin.
2. Zoom in until the Timeline shows 10 seconds or more before and after the cursor.
3. While holding down the Shift key, click 10 seconds to the right of the cursor.
   • Note that this is just like selecting a range of text in a word processor
4. Press Space to listen to the entire selection. Playback will stop when the end of the selection is reached.
5. Adjust the start and end of the selection with the mouse as follows.
   • 5.1. Move the pointer over the start of the selection - the cursor will change to a left-pointing hand.
   • 5.2. Click and drag to adjust the beginning of the selection.
   • 5.3. You can adjust the end of the selection in a similar manner.
6. Press Space to listen to the adjusted selection. You do not have to listen to all of it; press Space again at any time to stop playback.
   • A convenient way to listen to only the adjusted start of the selection is to move the mouse pointer a little after the start of the selection then press B. The selection plays from the start of the selection to the pointer. To hear the adjusted end of the selection, move the pointer close to the selection end, then press B to play from the pointer to the selection end.
   • You can also play a length of audio either side of the selection by pressing C. This lets you make sure there is no audio you want to keep that will be removed. Playing either side of the selection would also be useful if you later wanted to cut a small piece out of that selection - you would select the small piece to be cut, then could preview how the audio would sound after the cut. To adjust the length of audio played before and after the selection, go to Cut Preview in the Playback Preferences.

Keyboard use: Use the arrow keys to adjust the selection start and end.

1. Pressing Shift + Left will expand the selection to the left.
2. Pressing Shift + Right will expand the selection to the right.
3. Pressing Shift + Ctrl + Left will contract the selection from the right.
4. Pressing Shift + Ctrl + Right will contract the selection from the left.

Keyboard use: Use Selection Toolbar to create or adjust a selection.

1. Without a mouse, use Ctrl + F6 to navigate into Selection Toolbar, then Tab between the controls.
2. In 'Selection Start', type the starting point of your selection if there is not yet a selection.
3. Select the radio button above the second group of numbers in Selection Toolbar if it is not yet selected.
4. If there is no selection yet, select the digit after the 'm' in the 'Length' box and type 1 (one) on your keyboard. This selects exactly 10.000 seconds from the starting point you chose.
5. Once there is a selection, you can adjust its length in the same way. Let's suppose you dragged a little less than 10 seconds in the waveform, but you need the selection to be exactly 10 seconds.
   1. Select the first digit to the right of the decimal point in the 'Length' box.
   2. Type 0 (zero) - the digit changes to zero, the digit to the right is selected and the selection in the waveform changes to match.
   3. Type 0 (zero) twice more - the selection length is now 10.000 seconds, accurate to one thousandth of a second.

You've now selected the portion of the audio that you want to keep. Make sure you have pressed Space to stop if the track is still playing, then to delete everything except the selected audio, click on Edit > Remove Special > Trim Audio.

If you make a mistake, you can always click on Edit > Undo. Audacity has unlimited Undo and Redo. You can undo your editing actions all the way back to when you imported the file. You can also Redo actions that you have undone.

You now have a region of audio that starts several seconds (or perhaps minutes) from the beginning of the track. You could move the audio to the beginning of the track, using Tracks > Align Tracks > Start to Zero, but this is not a necessary step because when exporting, Audacity will ignore the white space between time zero and the start of the audio.

Step 6: Fade out the last second

• Click the Skip to End button .
• Zoom In until you can see the last two or three seconds of the waveform.
• Click in the waveform about 1 second before the end.
• Click on Select > Region > Cursor to Track End.
• Click on Effect > Fade Out. The last second of the audio is smoothly faded out.

Note that we always select some audio first, then choose what action we want to perform on it.

Step 7: Export the resulting file

When you save an Audacity project with File > Save Project > Save Project you are doing just that - saving an Audacity project. Audacity projects can be opened only by Audacity. If you want other applications (such as Apple Music/iTunes or Windows Media Player) to be able to open this file you need to export it.

Before we export this 10 second clip to a separate file we're going to simplify things a bit. Go to the Import / Export Preferences, and under When exporting tracks to an audio file uncheck 'Show Metadata Editor prior to export step'. Metadata Editor adds extra information about the speech or music into the file - see For More Information below to learn more. You can go back to the Import / Export Preferences at any time to re-enable Metadata Editor.

Exporting a WAV file

• Click on File > Export > Export Audio. - the standard 'Save' dialog for your operating system appears.
• Give the file a different name. Audacity always suggests a name for the file that is the same as the name of your Audacity project. It is always best to alter this so you do not confuse your exported file with your Audacity project.
• Choose a location to save the file in the usual manner.
• At the bottom of the Save dialog is a dropdown menu labeled 'Format'. From this menu choose 'WAV (Microsoft) signed 16-bit PCM'.
• There are no options for the WAV file format, so there is no need to click the button.
• Click the button to complete the export of your project to a WAV file.

Exporting an MP3 file

The steps for exporting a file in MP3 format are the same as for a WAV file, except:

• In the Save dialog, from the 'Format' menu, choose 'MP3 files'
• Then click the button to set the bit rate and other options for the MP3 file.

Audacity Editing Audio

Step 8 - Testing your new Audio Production

To demonstrate the difference between an Audacity project (the AUP) file, and a sound file you export from an Audacity project:

• Click on File > Close, saving changes if asked.
• Find the AUP file on your computer and attempt to open it with the audio player of your choice (for example iTunes, Windows Media Player). You cannot.
• Find the exported WAV file on your computer and attempt to open it with the audio player of your choice. Success!

You cannot open an Audacity project in a media player. Only by exporting your project can you listen to it in a media player.

Once you've exported your project you may want to keep the original project file (AUP) and its associated _data folder around in case you want to make some changes to it in the future.
