Built in AudioFX

PATCHBAY ships with a small set of built-in AudioFX implemented as regular plugins (pure NumPy). They live in the repository/package under plugins/ and are auto-discovered like any other effect.

See also:

• AudioFX Plugins (discovery, ordering, per-stream persistence)
• AudioFX Plugin API (how to implement your own)

Included effects (default)

plugin_id	Display name (UI)	Typical use	Details
normalize	Normalisierung	peak-normalize a stream to a target peak	[[AudioFX/Normalize
compressor	Kompression	light dynamics control on target/residual	[[AudioFX/Compressor
declicker	De-Klicker (Impuls-/Click-Entfernung)	remove short clicks/pops on residual stems	[[AudioFX/De-Clicker
highpass	Hochpassfilter	remove rumble/handling noise in residual	[[AudioFX/High-pass Filter
lowpass	Tiefpassfilter	tame hiss / high-frequency artefacts	[[AudioFX/Low-pass Filter
noise_reduction	Rauschunterdrückung (spektral)	attenuate steady noise (hiss/hum)	[[AudioFX/Spectral Noise Reduction

Notes:

• plugins/_template_gain.py is shipped as a template and is ignored by discovery because the filename starts with _. Rename it (remove the underscore) if you want to use it as a real plugin.
