M4A is the default recording format for iPhones, iPads, and Mac Voice Memos — if you've ever recorded something on an Apple device, it's almost certainly saved as an M4A file. Our converter transcribes M4A audio with the same 98%+ accuracy as any other format. Just upload the file from your phone or computer and get a full transcript in minutes.
M4A uses Apple's AAC compression, which preserves audio quality while keeping file sizes small. This makes it ideal for voice recordings, interviews, and meetings captured on mobile devices. Our AI handles M4A natively — no need to convert to MP3 or WAV first. Speaker diarization identifies different voices, and timestamps let you jump to any point in the original recording.
Perfect for students transcribing lecture recordings from their phone, journalists converting interview voice memos to text, and professionals turning meeting recordings into written notes. Export your M4A transcript as TXT, Word, PDF, or SRT subtitles.
