Sourceexception Closed

Raised when trying to play or close * a closed device.

Sourceexception Invalid_value

Raised when passing an invalid parameter's value.

Sourceval get_default_driver : unit -> driver_t

Get default driver

Sourceval drivers : driver_t list

drivers is a list of available drivers.

Sourceval open_live : ?bits:int -> ?rate:int -> ?channels:int -> ?channels_matrix:string -> ?byte_format:byte_format_t -> ?options:(string * string) list -> ?driver:driver_t -> unit -> t

open_live. * The channels_matrix parameter is * used only if the module is compiled against * libao >= 1.0.

Sourceval open_file : ?bits:int -> ?rate:int -> ?channels:int -> ?channels_matrix:string -> ?byte_format:byte_format_t -> ?options:(string * string) list -> ?driver:driver_t -> ?overwrite:bool -> string -> t

open_file. * The channels_matrix parameter is * used only if the module is compiled against * libao >= 1.0.

Sourceval find_driver : string -> driver_t

find_driver name returns the driver associated with the given short * name.

Sourceval play : t -> string -> unit

play device buf plays the sequence of samples in buf.

Sourceval close : t -> unit

close device closes the given device.

Backward compatibility functions, do not use them in new code.
