Audio joiner FAQ

Can I put an introduction before a separate interview take?

Select the introduction first and the take second. The joiner plays them in file order. Listen across the join for a repeated breath or a sudden change in room tone.

Does the join mix music underneath a voice?

Each file plays after the previous one ends. Layering a music bed underneath speech needs separate tracks in an audio editor.

What format is the joined track?

The files are converted to 48 kHz stereo for joining, then encoded into one 192 kbps MP3.

Why is there a pause at a join?

Leading or trailing silence in either source stays in the sequence. Trim those edges in the individual takes and join them again.

How do I hear the order of the example clips?

Play the dining room and kitchen samples separately, then play the joined track. In the example the kitchen comes in at about four seconds.

Can I join recordings made at different sample rates?

Yes. The joiner resamples the inputs to 48 kHz stereo before it creates the combined MP3.

Why does one segment sound louder after joining?

Joining puts the recordings end to end without matching their levels. If they need separate gain adjustments, prepare each take before joining.
