Audacity is a free and open-source digital audio editor and recording application software, available for Windows, macOS/OS X, and Unix-like operating systems.
To “drop-in” correction to a recorded track, you have to use a new track for each take. This is going to let you hear a “lead in” and “lead out” and, if needed, to make multiple attempts at correcting, from which we can select and use the one that we like best.
How to drop-in repair of Recording?
We are going to show you how to drop-in repair of recordings.
First of all, you have to make a backup copy of the track, so if you do something wrong with it, you can easily go back to that track. In this method, the track has been duplicated using Ctrl+D and muted using the Mute button.
It is useful to destroy this track to save screen space by clicking the Track Collapse button. By using this the bad part has been silenced.
You have to make sure that Audacity set for overdubbing in the Recording Preferences.
You also have to turn off “Software Playthrough”.
After that, you have to make the selection a bit long so that there is some lead-in and lead-out.
You will be now ready to record the “drop-in”. A new track is needed to record it, hold the “Shift” button and Record button is going to change to “Record New Track”.
Then, you have to click on that button and Audacity will start recording on a new track, and will stop automatically when it reaches the end of the selection.
Press the Play button and you will be able to listen to the drop-in repair you had made.
