Rawr DSP roadmap

Rawr DSP is a pretty big undertaking, so this should help organization.

Stage 0.1: Proof of concepts

Create proof-of-concepts that our core techniques will work.

• Proof of concept of (seamless) double-buffering source
  • Chrome
  • Firefox
  • Safari
• Proof of concept of decoding MP3 frame-by-frame
  • Chrome
  • Firefox
  • Safari
• Proof of concept HTTP response streaming into individual MP3 frames
  • Chrome
  • Firefox
  • Safari
• Proof of concept of decoding Opus frame-by-frame
  • Chrome
  • Firefox
  • Safari

Stage 1: Implement the core basics

Start building the basics of rawr dsp

• Shared tools
  • Automatic audio context use and resuming
• Double buffering source
• Queue source
• Chunking sink
• Codec chunkers
• Decoders for easy or particularly desirable formats
  • WAV
  • FLAC
  • QOA (not common but should be useful for testing)
  • MP3 (!!!!)
  • Opus
  • AAC
  • Vorbis
• Chunk aligner
• Chunk auto combiner
• Core HTTP streaming implementation

Stage 2: modular API

• RMStream
• Wrap all core functions in stream versions
  • HTTP
  • Queue source
  • Decoders
  • Aligner and other utils

Stage 3: high level api

• Audio player that takes a possibly incomplete stream of frames and plays it
  • Can play back when input is healthy
  • Automatically wait when input is empty
  • Seeking (requires buffering past input)
  • Automatic disposal of input stream
