Sources are machines that generate audio.

Functions

bt_source_machine_new ()

BtSourceMachine *
bt_source_machine_new (const BtSong * const song,
                       const gchar * const id,
                       const gchar * const plugin_name,

                       GError **err);

Create a new instance The machine is automaticly added to the setup from the given song object. You don't need to add the machine with

bt_setup_add_machine(setup,BT_MACHINE(machine));.

Parameters

song

the song the new instance belongs to

 

id

the id, we can use to lookup the machine

 

plugin_name

the name of the gst-plugin the machine is using

 

voices

the number of voices the machine should initially have

 

err

inform about failed instance creation

 

Returns

the new instance or NULL in case of an error

Types and Values

struct BtSourceMachine

struct BtSourceMachine;

Sub-class of a BtMachine that implements a signal generator (a machine with outputs only).
