type converter = float -> float array -> int -> int -> float array

A converter takes a convertion ratio (output samplerate / input samplerate), an audio buffer, an offset in the buffer, a duration in the buffer and returns a resampled buffer.

type converter_plug = unit -> converter

type t

val samplerate_conf : Dtools.Conf.ut

val converters : converter_plug Plug.plug

val create : int -> t

create chan_nb creates a converter.

val resample : t ->
       float -> float array array -> int -> int -> float array array

resample converter ratio data offset length: converts input data at given ratio. Raises Invalid_data if number of channels do not match the number passed at create.
