Why File Formats Matter
In the music industry, audio files serve two main jobs:
1. Pitching
You need:
- Fast streaming
- Small file size
- Metadata that travels
- Easy sharing
Best format: MP3
2. Playback & Delivery
You need:
- High-quality audio
- Downloadable master files
- Compatibility with editing systems
Best formats: WAV or AIFF
To work efficiently, you need both types of files - and they need to stay organized.
WAV vs AIFF vs MP3 (Quick Comparison)
Why WAV Files Don’t Carry Metadata
This is the #1 source of confusion.
You may see metadata displayed in iTunes alongside a WAV file — but that data is not actually written to the file in a way that travels.
Here’s what happens:
- iTunes stores metadata locally
- The WAV file itself does not reliably carry ID3v2 metadata
- When uploaded to DISCO (or opened in other software), that metadata disappears
Even though some tag editors can embed metadata into WAV files, most industry tools don’t read it consistently.
For simplicity:
Treat WAV files as if they do not carry metadata.
If you need metadata to travel, convert your WAV to AIFF or MP3 first.
Encoding vs Transcoding (Simple Version)
Encoding
When audio is recorded, it is encoded into a digital file format (WAV, AIFF, MP3, etc.).
Transcoding
Converting one format into another (e.g., WAV → MP3).
Important:
You can’t convert a low-quality MP3 back into a high-quality WAV and restore lost detail.
Always start with your highest-quality source file.
When to Use Each Format
Pitching Music
Use:
- MP3
- Small file size
- Streamable
- Metadata travels
Decision-makers prioritize speed and accessibility.
Delivering Final Audio
Use:
- WAV or AIFF
- High-quality
- Downloadable
AIFF is often preferred in sync because it carries metadata and maintains quality.
How DISCO Simplifies File Management
Managing multiple formats manually is messy:
- Separate folders
- Duplicate files
- Manual transcoding
- Re-tagging metadata
DISCO eliminates this complexity.
One Track, Multiple Formats
In DISCO, a single “Track” can link:
- A high-quality original file (WAV or AIFF)
- An optimized streaming file (MP3)
They stay connected automatically.
No duplicate folder chaos.
Automatic Transcoding
When you upload:
- WAV or AIFF → DISCO automatically generates an MP3
- MP3 → DISCO does NOT generate a WAV
On Artist and Pro plans (and above), you can also convert:
- WAV ↔ AIFF
This means you can have:
- WAV (master)
- AIFF (editable high-quality)
- MP3 (streamable pitch file)
All attached to one track.
Replacing & Managing Formats
You can:
- Replace audio files at any time
- Add additional formats
- Customize what appears in the Track Info hover
Everything stays structured and centralized.
Best Practice Workflow
- Start with high-quality WAV files
- Upload to DISCO
- Let DISCO auto-generate MP3s
- Add clean metadata to MP3 and AIFF formats
- Pitch using streamable files
- Deliver using high-quality originals
You no longer need separate folders for every format.
Wrap-Up
You don’t need to become a digital audio engineer.
You just need to remember:
- MP3 for pitching
- WAV/AIFF for delivery
- WAV doesn’t reliably carry metadata
- DISCO links formats automatically
When your formats and metadata are handled correctly, your workflow becomes faster, cleaner, and more professional.
