Going to WAV keeps every sample intact for editing; 192 kbps MP3 is the sweet spot for voice memos and sharing — 320 only matters for music on good headphones.
M4A plays fine on phones and computers, but plenty of car stereos, cheap MP3 players, voice-editing apps and old software still refuse it. MP3 is the lowest common denominator — converting removes the compatibility problem for good.
192 kbps for voice memos, lectures and sharing; 320 kbps only for music you will hear on decent headphones. Going from a 128 kbps source to 320 adds size but no quality — the detail was already gone.
Whatever your browser cannot decode: usually protected iTunes M4P files and some exotic codecs. Everything mainstream — MP3, WAV, M4A, OGG, WebM, FLAC — converts fine.
