# Configures a running Pulseaudio instance with an LADSP filter that
|
|
# creates a noise-cancelling sink.
|
|
#
|
|
# This can be used to, for example, cancel noise from an incoming
|
|
# video conferencing audio stream.
|
|
#
|
|
# There are some caveats, for example this will not distinguish
|
|
# between noise from different participants and I have no idea what
|
|
# happens if the default sink goes away.
|
|
#
|
|
# If this script is run while an NSFV sink exists, the existing sink
|
|
# will first be removed.
