Il bouncing è il salvataggio di più tracce audio su disco come un’unica traccia.
Il termine deriva da quando Pro Tools poteva gestire soltanto quattro tracce contemporaneamente e quindi per gestirne più di quattro, queste venivano salvate (bounced) su disco per poter continuare a scriverci sopra.
Bounce is a term that comes from Pro Tools (i.e. Bounce to Disk). If you go back to the very first incarnation of Pro Tools, it was basically a software version of a 4 track recorder.
When you were recording 4 tracks simultaneously but you needed a 5th track, you had to use bounce to disk. This would flatten 4 tracks of live audio into 1 track of recorded audio which is saved on tape or a hard disk.
That recorded audio track is retrieved from disk and fills the first track on the multi-track recorder freeing up 3 tracks for additional live recording (overdubbing).
Bounce therefore means to render multiple tracks to tape/disk and then play it back from tape/disk instead of the source so you can continue live recording over it. You can think of it as bouncing 3 live tracks from the tracker down to 1 recorded track on a hard drive and then back up from the hard drive to the tracker. Clear 3 tracks and then overdub additional tracks.
