Module `Mm_audio.Audio`Source

Operations on audio data.

Sourceval samples_of_seconds : int -> float -> int

At given sample rate, number of samples in given amount of time.

Sourceval seconds_of_samples : int -> int -> float

At given sample rate, duration of given number of samples.

Sourceval lin_of_dB : float -> float

Convert decibels to linear coefficient.

Sourceval dB_of_lin : float -> float

Convert linear coefficient to decibels.

Sourcemodule Sample : sig ... end

Operations on samples.

Sourcemodule Note : sig ... end

Operations on notes.

Sourcemodule Mono : sig ... end

Operations on mono buffers (with only one channel).

Sourcetype t = Mono.t array

An audio buffer.

Sourcetype buffer = t

Sourceval create : int -> int -> t

create chans len creates a buffer with chans channels and len samples as duration.

Sourceval make : int -> int -> float -> t

Sourceval of_array : float array array -> t

Sourceval to_array : t -> float array array

Sourceval create_same : t -> t

Create a buffer with the same number of channels and duration as the given buffer.

Sourceval clear : t -> unit

Clear the buffer (sets all the samples to zero).

Sourceval copy : t -> t

Copy the given buffer.

Sourceval append : t -> t -> t

Sourceval channels : t -> int

Sourceval length : t -> int

Length of a buffer in samples.

Sourceval to_mono : t -> Mono.t

Convert a buffer to a mono buffer by computing the mean of all channels.

Sourceval of_mono : Mono.t -> t

Convert a mono buffer into a buffer. Notice that the original mono buffer is not copied an might thus be modified afterwards.

Sourceval noise : t -> unit

Sourceval amplify : float -> t -> unit

Amplify a portion of the buffer by a given coefficient.

Sourceval pan : float -> t -> unit

Pan a stereo buffer from left to right (the buffer should have exactly two channels!). The coefficient should be between -1. and 1..

Sourceval add : t -> t -> unit

Sourceval add_coeff : t -> float -> t -> unit

Sourcemodule Buffer_ext : sig ... end

Buffers of variable size. These are particularly useful for temporary buffers.

Audio effects.

Sourcemodule Generator : sig ... end

Sound generators.

Sourcemodule IO : sig ... end

Operation for reading and writing audio data from files, streams or devices.
