If preferred you can disable this behaviour in the Tracks Preferences by unchecking Select all audio in project, if none selected. Menu items requiring a selection will then be grayed out if there is no selection.
Why can't I select less than one second or click between whole seconds ?
Uncheck Snap To in Selection Toolbar. If Snap To is checked, the selection must be an exact unit of length or the cursor must be placed at an exact unit of time, according to the current Selection Format.

To mix two files, import both of them into Audacity. They will appear in separate tracks.
When you press the Play button, you'll hear both tracks play together. Because this adds the sounds together, the end result may become too loud and distorted. To fix this, turn down the -...+ gain sliders on each track until you see no clipping light on the Meter Toolbar. Use the L...R pan sliders to adjust the spatial position of each track in the mix. You can also use to display the controls for each track together in a separate window.
When you use select the tracks, then .
, the tracks will be automatically mixed to an audio file for use in other applications. If you want to mix tracks together explicitly before export, so that they are replaced with a single mixed track,Can I remove the vocals from a recording to make a Karaoke track?
This is only possible for certain stereo tracks. When the vocals are exactly the same on both stereo channels, you can remove them by “subtracting” one channel from the other. This works for recordings where the vocal track is mixed exactly in the center and stereo reverberation has not been added. See this tutorial: Vocal Removal and Isolation.
Can I create Ringtones with Audacity?
See this tutorial in the Manual: Making Ringtones.
Why do I see a lot of vertical red lines in the track I just recorded?
This happens when you have an oversaturated recording, where clipping has occurred, that is, the signal has exceeded the maximum allowed level. The vertical red lines show where clipping has happened. The clipping indicators can be turned on and off (Audacity's default setting is "off") by selecting .
See the Audacity Waveform page for more explanation of how the waveform is displayed.
Can Audacity preview or apply effects live, in real time?
Audacity cannot yet apply effects in real time while you are previewing or recording. This is one of the most commonly asked for Feature Requests, but it requires substantial changes to Audacity to implement it. If you would like us to add your vote please either e-mail our feedback address or post on the Adding Features to Audacity section on the Audacity Forum.
Advanced users can apply effects to recordings in real time by applying the effects in a VST host and routing the effect output to be recorded by Audacity. See this Forum topic and ask on the Forum if you need any help.
