DSP Library

Philosophy

TODO short overview of the DSP library philosophy.

Basic DSP Components

After a statement like from tiliqua import dsp, these can be accessed through dsp.Split or similar:

• Delay Lines
  • DelayLine
  • DelayLineTap
• Filters
  • SVF
  • FIR
  • DCBlock
• Oscillators
  • SawNCO
• Effects
  • WaveShaper
  • PitchShift
• VCAs
  • VCA
• Mixing
  • MatrixMix
• Resampling
  • Resample
• One-shot
  • Trigger
  • Ramp
• Stream utilities
  • Splitting / merging streams
  • Remapping streams
  • Connecting streams in feedback loops
• Miscellaneous utilities
  • named_submodules()

Specialized Modules

These require qualified access - after a statement like from tiliqua import dsp, these can be accessed through dsp.fft.STFTProcessor or similar:

• Delay Effects
  • PingPongDelay
  • Diffuser
  • Boxcar
• FFT Processing
  • FFTs
  • Windowing
  • Overlap / Add
  • STFTs
• Spectral Processing
  • SpectralCrossSynthesis
  • SpectralEnvelope
• MAC Operations
  • MAC
  • MuxMAC
  • RingMAC
  • RingClient
  • RingMACServer
• Block-based Processing
  • Block
  • WrapCore
• Complex Numbers
  • CQ
  • Polar
• Trigonometry / CORDIC
  • RectToPolarCordic
