Worked example
Convert WAV to M4A (AAC) for Apple devices, messaging and uploads: pick M4A and 192 kbps for music or 128 kbps for speech.
WAV to M4A is lossless to lossy, so the quality you keep depends on the bitrate you choose. The tool uses FFmpeg's built-in AAC encoder, and AAC is generally designed to hold up better than MP3 at the same bitrate, though dense music still benefits from 192 or 256 kbps.
Size math for a 3-minute demo: the WAV is 180 s × 176,400 bytes, about 31.75 MB. At 128 kbps M4A it is 2.88 MB, at 192 kbps 4.32 MB, at 256 kbps 5.76 MB and at 320 kbps 7.2 MB, so the default 192 kbps is about 14 percent of the WAV.
Scenario: a songwriter sends a rough mix through a messaging app with a file-size limit. 128 or 192 kbps is plenty for a demo, and a mono mix can use Channels set to 1. Anything that goes on to mastering or video editing should stay WAV.
Common mistake: exporting from the editor with peaks at 0 dBFS; AAC encoding can overshoot slightly and clip. Fix: leave about 1 dB of headroom in the WAV first. Check by playing the loudest chorus for crackle and confirming the M4A duration matches the WAV within a second.

Older players can be fussy about M4A, so test the file on the device that will actually play it.
