Build a mix that fits together
Combined audio
A place for every recording
Put a voice over music, combine sound effects or line up separate takes. Each recording keeps its own position and volume so you can build the balance a track at a time.
Check the whole mix
Preview overlapping sections before saving. Keep peak protection enabled when adding several loud tracks, and lower individual volumes if a part dominates the mix.
Audio Combine questions
Does Audio Combine join files one after another?
It layers clips on a shared timeline. To place them end to end, set each timeline position to begin where the previous clip finishes.
Can I use only part of a track?
Yes. Adjust that track’s start and end points, then set where the selected passage begins in the combined recording.
What if a track is too loud?
Lower its volume or mute it while checking the other parts. Peak protection reduces the combined level when needed to avoid clipping.
Which formats can I save?
Save your combined recording as WAV, MP3 or AAC. Longer tracks and larger mixes take more time and memory to process.
