Audio Mixer
Layer selected recordings so they play together from the beginning. Adjust the overall mix gain and export a combined WAV with the length of the longest track.
- Layer up to 16 tracks simultaneously
- Keep the longest source duration
- Scale the mix down when sample peaks would clip
Start the sources together
Every selected track begins at time zero. Prepare offsets or leading silence beforehand if one recording should enter later.
Set the overall output gain
The gain control affects the combined result. This is not a multitrack console with separate faders and automation for every source.
Check overlapping peaks
Layering can create higher peaks than any source alone. The result is scaled down when needed to avoid exceeding sample full scale.
Handle shorter tracks predictably
Shorter recordings contribute silence after they finish. The mix continues until the longest source ends.

Audio Mixer FAQs
Use Audio Joiner for sequential playback; this mixer starts them together.
No. It does not provide a timeline or independent track offsets.
Prepare the voice and music at suitable levels, then select both tracks in the mixer. They start together, and the result lasts as long as the longest source. This mixer uses overall gain rather than separate track faders; adjust an individual source before mixing when necessary.
Audio Mixer schedules a background render after a setting changes. The completed preview or analysis replaces the previous result automatically. Processing time depends on recording length and device performance; the status message shows when the new result is ready.
