Module `Audio.Effect`Source

Audio effects.

Sourceclass type t = object ... end

A possibly stateful audio effect.

Sourceclass chain : t -> t -> t

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

Sourceclass type delay_t = object ... end

Source

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).

Source

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. Given parameters are attack and release in seconds, ratio n means n:1 compression, threshold and knee in dB, and rms_window in second is the duration for RMS acquisition. gain is an additional pre-gain.

                 | `Low_shelf
                 | `High_shelf ] -> ?gain:float -> float -> float -> 
  t

A biquadratic filter. gain in dB is only used by peaking, low and high shelves.
