# On Mac it defaults to 'portaudio' or 'fifo'
# On Windows this is automatic and no input settings are needed.
#
# Each input method uses the same config variable 'source'
# to define where it should get the audio.
#
# For pulseaudio and pipewire 'source' will be the source. Default: 'auto', which uses the monitor source of the default sink
# (all pulseaudio sinks(outputs) have 'monitor' sources(inputs) associated with them).
#
# For pipewire 'source' will be the object name or object.serial of the device to capture from.
# Both input and output devices are supported. To capture the monitor source of a sink node, append '.monitor' to the sink's object name.
#
# For alsa 'source' will be the capture device.
# For fifo 'source' will be the path to fifo-file.
# For shmem 'source' will be /squeezelite-AA:BB:CC:DD:EE:FF where 'AA:BB:CC:DD:EE:FF' will be squeezelite's MAC address
#
# For sndio 'source' will be a raw recording audio descriptor or a monitoring sub-device, e.g. 'rsnd/2' or 'snd/1'. Default: 'default'.
# README.md contains further information on how to setup CAVA for sndio.
#
# For oss 'source' will be the path to a audio device, e.g. '/dev/dsp2'. Default: '/dev/dsp', i.e. the default audio device.
# README.md contains further information on how to setup CAVA for OSS on FreeBSD.
#
# For jack 'source' will be the name of the JACK server to connect to, e.g. 'foobar'. Default: 'default'.

# Output method. Can be 'ncurses', 'noncurses', 'raw', 'noritake', 'sdl'

# prone to tearing (vsync issues) than 'ncurses'.

# stream of the bar heights that can be used to send to other applications.
# 'raw' defaults to 1024 bars stereo (512 bars mono), which can be adjusted in the 'bars' option above.

# in graphic mode. It only support the 3000 series graphical VFDs for now.
