This page is meant to track ideas about low-delay, high-quality audio coding. The work has just started, so don't expect anything in the near future (or at all for that matter).

Signal types

There are many signal types that can be found:

• Sinusoids
  • A few pure (or nearly pure) tones
• Harmonic
  • Periodic waveforms (e.g. voice)
  • Many (sometimes closely spaced) harmonics
• Shapred noise
  • Signals that are (or are indistinguishable) from filtered (coloured) white noise
• Transients
  • Whatever does't fit above I guess
