Roadmap

[lovesegfault]

Following the discussion on IRC in the past couple of days, I thought it would be fitting to work on a roadmap to be able to implement an MP3 decoder in pure Rust. These are the resources we have

Other Decoders

• Fluendo (C)
• mp3decoder (Haskell)
• mp3dec (C)
• pyMP3 (Python)
• minimp3 (C)
• Many others

Resources

• The Theory Behind MP3
• How is MP3 Built
• MPEG Audio Basics
• Let's Build an MP3 Decoder

---

Roadmap of the project:

• [x] header parsing (#4)
• [ ] obtain sample files (#7)
• [x] frame parsing (#8)
• [ ] bit reader
• [ ] Layer I
• [ ] Layer II
• [ ] Layer III
  • [ ] side information decoder
  • [ ] huffman decoder
  • [ ] imdct implementation
  • [ ] synth
  • [ ] TBD

Hi, may be this helps https://github.com/germangb/minimp3-rs . It can be transformed to pure rust step-by-step.

@lieff That actually is extremely useful!

@lieff Could you look on #7 and maybe help us understand those files?
