Reliable Audio MIME types reference

This list helps teams keep audio mime types consistent across APIs, uploads, docs, and frontend experiences.

Audio MIME types split roughly into lossy compressed formats built for streaming (audio/aac, audio/mpeg, audio/opus), lossless formats for archival or editing (audio/flac, audio/wav), and the mobile/browser container types you'll see from recording APIs (audio/3gpp, audio/webm). This list gives you 12 real-world audio MIME types in copy-ready text, JSON, or HTML <option> format, so upload validation, <audio> playback checks, and processing pipelines reference the correct type for the quality and platform you're targeting.

Lossy and lossless, side by side

Compressed streaming formats and lossless archival formats are both here, so you can pick based on quality needs, not guesswork.

  • audio/aac, audio/mpeg, audio/opus (lossy)
  • audio/flac, audio/wav (lossless)
  • audio/midi, audio/x-midi (notes, not recorded sound)
Mobile and browser formats included

Covers the container types you'll hit from mobile recording and browser APIs, not just desktop-era formats.

  • audio/3gpp, audio/3gpp2
  • audio/webm (MediaRecorder output)
  • audio/mp4
One click, three formats

Grab the list as plain text, a JSON array, or ready-to-paste HTML <option> tags.

Matching audio MIME types to quality needs

The right audio type depends on whether you're optimizing for file size, quality, or compatibility.

  • Serve audio/aac or audio/opus for compressed streaming, and audio/flac or audio/wav when lossless quality matters.
  • Use audio/webm for audio captured with the browser's MediaRecorder API rather than guessing a codec-specific type.
  • Treat audio/midi (and its audio/x-midi alias) separately from the rest — it stores notes and instrument instructions, not a compressed recording.

Frequently asked questions

What's the difference between audio/mpeg and audio/mp4?>
audio/mpeg is the type for standard MP3 audio streams. audio/mp4 wraps audio (often AAC) inside an MP4 container, which is a different file structure entirely.
Is audio/wav a lossless format?>
Yes. WAV stores uncompressed PCM audio, making it lossless but significantly larger than compressed formats like MP3 or AAC.
What MIME type does browser-recorded audio use?>
Audio captured with the MediaRecorder API is typically produced as audio/webm, which you should check for explicitly rather than assuming a fixed codec.
