Audio File Formats for Music Production
Music production requires understanding the strengths and tradeoffs of different audio formats at each stage of the workflow — recording, editing, mixing, and distribution.
Key Takeaways
- Always record in an uncompressed lossless format.
- ## Recording Stage Always record in an uncompressed lossless format.
- Never convert to a lossy format and back — each lossy encoding cycle permanently removes data.
- Always generate lossy formats from the lossless master, never from another lossy format.

Recording Stage
Always record in an uncompressed lossless format. WAV (PCM) at 24-bit/48 kHz is the industry standard. 24-bit provides 144 dB of dynamic range, eliminating the need to record "hot" (close to 0 dB). 48 kHz is the standard for video-synced audio; 44.1 kHz is standard for music-only production. Higher sample rates (96 kHz, 192 kHz) offer marginal benefits for most recording scenarios.
Editing and Mixing
Keep everything in WAV or AIFF during editing and mixing. Never convert to a lossy format and back — each lossy encoding cycle permanently removes data. Your DAW's project file references these lossless files; the project itself stores mix settings, plugin parameters, and automation data.
Mastering and Delivery
The master file should be WAV 24-bit at the project sample rate. From this master, create distribution formats: WAV 16-bit/44.1 kHz for CD, FLAC for lossless digital distribution, MP3 320 kbps for compatibility, and AAC 256 kbps for iTunes/Apple Music. Always generate lossy formats from the lossless master, never from another lossy format.
Format Comparison for Distribution
| Format | Quality | File Size | Compatibility |
|---|---|---|---|
| WAV 16/44.1 | Lossless | ~10 MB/min | Universal |
| FLAC | Lossless | ~6 MB/min | Excellent |
| ALAC | Lossless | ~6 MB/min | Apple ecosystem |
| MP3 320 | Lossy (excellent) | ~2.5 MB/min | Universal |
| AAC 256 | Lossy (excellent) | ~2 MB/min | Excellent |
| OGG 192 | Lossy (good) | ~1.5 MB/min | Good |
Metadata
Embed metadata in all distribution files: artist, title, album, track number, genre, year, and artwork. Use a consistent naming convention for files: Artist - Album - TrackNumber - Title.ext. For streaming platforms, ensure metadata matches your distributor's requirements exactly.
