elkpy.AudioGraphController

class elkpy.audiographcontroller.AudioGraphController(address='localhost:51051', sushi_proto_def='/usr/share/sushi/sushi_rpc.proto')

Bases: object

A class to control the audio graph in sushi via gRPC. It has functions to create, move, delete and get info about audio graph object like tracks and processors.

Attributes:

_stub (AudioGraphControllerStub): Connection stubs to the gRPC audio graph interface implemented in sushi.

__init__(address='localhost:51051', sushi_proto_def='/usr/share/sushi/sushi_rpc.proto')

The constructor for the AudioGraphController class setting up the gRPC connection with sushi.

Parameters:

address (str): ‘ip-addres:port’ The ip-addres and port at which to connect to sushi. sushi_proto_def (str): path to .proto file with SUSHI’s gRPC services definition

create_multibus_track(name: str, output_busses: int, input_busses: int) → None

Create a new multibus track in sushi.

Parameters:

name (str): The name of the new track. output_busses (int): The number of output busses to assign the new track. input_busses (int): The number of input busses to assign the new track.

create_processor_on_track(name: str, uid: str, path: str, processor_type: elkpy.sushi_info_types.PluginType, track_id: int, before_processor: int, add_to_back: bool) → None

Create a new processor on an existing track.

Parameters:

name (str): The name to assign the processor. Must be unique. uid (str): The uid of an internal sushi processor or the URI of an LV2 processor. Not applicable for vst2 or vst3. path (str): The path to the processor library. Only for vst2 or vst3 processors. processor_type (info_type.PluginType): The type of processor to create. track_id (int): The id of the track to add the processor to. before_processor (int): Which existing processor to create the new processor in front of. add_to_back (bool): Set to true to add the processor to the back of the processing chain on the track.

create_track(name: str, channels: int) → None

Create a new track in sushi.

Parameters:

name (str): The name of the new track. channels (int): The number of channels to assign the new track.

delete_processor_from_track(processor: int, track: int) → None

Delete an existing processor from a track.

Parameters:

processor (int): The id of the processor to delete. track (int): The id of the track that contains the processor.

delete_track(track_id: int) → None

Delet a track.

Parameters:

track_id (int): The id of the track to delete.

get_all_processors() → List[elkpy.sushi_info_types.ProcessorInfo]
