module Type : sig ... end

Biquad filter type.

type opts

The type for BiquadFilterOptions.

val opts : 
  ?channel_count:int ->
  ?channel_count_mode:Channel_count_mode.t ->
  ?channel_interpretation:Channel_interpretation.t ->
  ?type':Type.t ->
  ?q:float ->
  ?detune:float ->
  ?frequency:float ->
  ?gain:float ->
  unit ->
  opts

opts () are analyser node options with given parameters.

type t

The type for BiquadFilter objects.

val create : ?opts:opts -> context -> t

create ~opts c creates a biquad filter node.

val as_node : t -> node

as_node n is n as an audio node.

val type' : t -> Type.t

type' n is the type of n.

val set_type : t -> Type.t -> unit

set_type n t sets the type' of n to t.

val detune : t -> Param.t

detune n is the frequency detuning of n.

val frequency : t -> Param.t

frequency n is the frequency of n.

val q : t -> Param.t

q n is the quality factor of n.

val gain : t -> Param.t

gain n is the gain of n.

val get_frequency_response : 
  t ->
  frequencies:Brr.Tarray.float32 ->
  mag_response:Brr.Tarray.float32 ->
  phase_response:Brr.Tarray.float32 ->
  unit

get_frequency_response n ~frequencies_hz ~mag_response ~phase_response calculates frequency responses for frequencies.
