Worked example
Convert M4A to MP3 for players and upload forms that only take MP3: choose MP3 and 192 kbps or more for music, 96 to 128 kbps for speech.
An .m4a file can hold AAC (lossy) or ALAC (lossless). From AAC the step is lossy to lossy and adds a second generation of artefacts; from ALAC it is an ordinary lossless-to-lossy encode, so 256 or 320 kbps is a fair choice. Look at the source codec in your player's info panel before choosing.
Size math: a 3-minute voice memo converted at 96 kbps MP3 is about 2.16 MB (0.72 MB per minute), while 192 kbps gives about 4.32 MB (1.44 MB per minute). A small memo does not stay small if you pick a high bitrate.
Scenario: an interview recorded as a voice memo has to reach a transcription site or an older car stereo that wants MP3. Spoken word holds up at 96 to 128 kbps. For a one-person recording set Channels to 1, so the single voice gets the whole bitrate instead of sharing it with a near-identical second channel. Music should stay at 192 kbps or above.
Common mistake: expecting chapter marks, lyrics or artwork to survive. Fix: re-add tags afterwards in a tag editor. Check on the target device that the duration matches within a second and listen to the start of the first word; MP3 encoding adds about 25 ms of encoder delay, so gapless albums can show a tiny gap.
