Punching in allows you to record over a portion of a previously recorded track, overwriting the previous audio. The Spire app allows you to punch in and record over a track at the time of your choice! To start, select the track you’d like to record over.
Next, set the cursor to the spot where you would like to start recording over this track by dragging the circle at the bottom left or right, or simply pause playback at the spot where you want to start recording.
After selecting the spot where you want to start recording, press the red Record button at the bottom of the project to punch in! The app will provide a 1 bar lead-in to the spot you chose in the previous step.
