SID audio rendering primitives extracted from the preframr research codebase.

Project description

preframr-audio

SID audio rendering primitives extracted from the preframr research codebase.

Provides offline + real-time playback of pre-parsed register-event sequences through pyresidfp. Used by the preframr training/predict pipeline; published as a standalone package so the audio path can be installed without the full training stack.

Install

pip install preframr-audio

System dependencies: ALSA + libasound2 for the real-time driver (offline rendering to WAV works without ALSA).

Modules

  • preframr_audio.sidwav -- default_sid(), sidq(), write_reg(sid, reg, val, reg_widths).
  • preframr_audio.audio_driver -- render_to_wav() (offline), play_samples() (real-time via ALSA), ResidWorker, AudioRenderBuffer, FramePacket / FrameOp.
  • preframr_audio.live_animator -- terminal voice-state visualiser.

Stability

Library follows semver from v1.0. Pre-1.0 releases may break API as the preframr codebase evolves.
