# Example output
    id: 0
    permissions: rwxm
    type: PipeWire:Interface:Core/3
    cookie: 134115873
    user-name: "user"
    host-name: "user"
    version: "0.3.30" # Possibly more actual than this version
    name: "pipewire-0"

Tutorial

PLAY AND RECORD

from pipewire_python.controller import Controller

# [PLAYBACK]: normal way
audio_controller = Controller()
audio_controller.set_config(rate=384000,
                            channels=2,
                            _format='f64',
                            volume=0.98,
                            quality=4)
audio_controller.playback(audio_filename='docs/beers.wav')

# [RECORD]: normal way
audio_controller = Controller()
audio_controller.record(audio_filename='docs/5sec_record.wav',
                        timeout_seconds=5)

GET INTERFACES

from pipewire_python.controller import Controller

audio_controller = Controller()
# Return all Client Interfaces on Pipewire
audio_controller.get_list_interfaces(
    type_interfaces="Client",
    filtered_by_type=True,
)
# Return all interfaces
audio_controller.get_list_interfaces(
    filtered_by_type=False,
)

LINK PORTS

Linking Ports

from pipewire_python import link

inputs = link.list_inputs()
outputs = link.list_outputs()

# Connect the last output to the last input -- during testing it was found that
# Midi channel is normally listed first, so this avoids that.
source = outputs[-1]
sink = inputs[-1]
source.connect(sink)

# Fun Fact! You can connect/disconnect in either order!
sink.disconnect(source) # Tada!

# Default Input/Output links will be made with left-left and right-right
# connections; in other words, a straight stereo connection.
# It's possible to manually cross the lines, however!
source.right.connect(sink.left)
source.left.connect(sink.right)
