Increase the FC filter frequency to 12KHz for better dialogs. This
filter is only applied when making the FC from FRONT channels so that
we keep the high frequency signal on the FRONT mostly.
Increase LFE filter frequency to make slightly more bass.
Disable widen filter by default.
Update config files with the correct defaults.
Add a property to select the upmix method. PSD is enabled by default
but a new simple upmixing algorithm is available that duplicates
channels and avoids lowpass filter on the FC and disables widening.
Fixes#861
Add an option to do a hilbert transform on the generated rear channels
to do a 90 degree pahse shift on them. This can improve spacialization
of the rear channels.
See #861
Use invoke to set the zero-denormals flag from the data thread when
explicitly set. The flag is per thread and should really only be set on
the data thread and only when explicitly enabled.
Fixes#2160
This automatically configures the node in a supported format with the
highest amount of channels. Options are available to enable monitor
and to override the port channels as AUX or UNKNOWN.
Add an option to check if the rate and quantum configured with the
settings metadata is in the allowed range.
This is false by default, you can use metadata to set any rate/quantum
but in a minimal controlled setup you might want to restrict this.
Make the default nice.level an invalid value, that is not configured
as the priority on a process.
Explicitly enable a nice level on our daemon processes.
Fixes#2034
