Upload the AIFF file and the converter chooses the M4A codec and bitrate to match the source. Lossless M4A (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy M4A (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears. AIFF na adana PCM mai girma mai ƙunshe ba - Apple-side ma'ana na WAV, da daidaitacce bit-to-bit. A M4A riƙe AAC a cikin mafi yawan lokuta, ko Apple Lossless (ALAC) idan ya zo daga wani lossless rip.

+
Default is 192 kbps for lossy M4A; pass-through for lossless M4A. Override to 320 kbps for audiophile or 96 kbps for voice / podcast. The choice trades file size against audible fidelity; below 96 kbps lossy artifacts become noticeable on music.
