Audio Merger
Recordings get split — the phone ran out of space, the meeting had a break, the chapters came as separate files. This joins them back into one track, normalising the format first so the result doesn't glitch at the joins.

Questions
Can I reorder the files?
Yes — use the ↑ button in the file list before it runs. They're joined top to bottom.
What if the files have different formats?
That's handled. Everything is resampled to a common format before joining, which is what stops the audio glitching at each join.
How many files can I join?
Up to five at a time, 30 minutes total.
