Questions about M4A and WAV.
Check the format behavior, limitations, and follow-up options before processing a real file.
iPhone Voice Memos land as M4A, and the first thing many people need is to edit or transcribe them — trim an interview, clean up a lecture recording, feed a meeting to speech-to-text. Those tools want WAV. Converting decodes the AAC into standard PCM that Audacity, Premiere, and transcription pipelines accept directly. It doesn't add quality the recording never had; it removes the format obstacle.
