Module Audio.Effect

module Effect: sig .. end

Audio effects.

class type t = object .. end

A possibly stateful audio effect.

class chain : t -> t -> t

class of_mono : int -> (unit -> Audio.Mono.Effect.t) -> t

class type delay_t = object .. end

val delay : int ->
       int ->
       float -> ?once:bool -> ?ping_pong:bool -> float -> delay_t

delay chans samplerate d once feedback creates a delay operator for buffer with chans channels at samplerate samplerate with d as delay in seconds and feedback as feedback. If once is set to true only one echo will be heard (no feedback).

class compress : ?attack:float -> ?release:float -> ?threshold:float -> ?ratio:float -> ?knee:float -> ?rms_window:float -> ?gain:float -> int -> int -> object .. end

Hardknee compressor with RMS look-ahead envelope calculation and adjustable attack/decay.

A biquadratic filter.
