Converting WAV to M4A: what to know
WAV is converted to M4A to make a recording much smaller in the AAC format that iPhones, Macs, iTunes and most players support.
AAC compression is lossy, but at 192–256 kbps music is hard to tell from the original, and for speech 96–128 kbps is enough. Keep the original WAV if you need it for editing. Before saving, you can trim the recording or turn it into mono.
WAV or M4A: which to choose?
WAV (Waveform Audio File Format)
WAV stores uncompressed audio: maximum quality, but about 10 MB per minute.
Best for recording, editing and working in audio editors.
M4A (MPEG-4 Audio)
M4A is an MPEG-4 audio file, usually AAC - the format of Apple Music, iTunes and iPhone voice memos.
Best for music and voice recordings in the Apple ecosystem.
What happens when converting WAV to M4A
M4A compresses with loss: choose the bitrate - at 192–320 kbps it sounds close to the original.
Trim the fragment, convert stereo to mono or change the sample rate.
WAV files up to 512 MB are supported; the actual limit also depends on the free memory of your device.
