@ -121,14 +121,19 @@ Set cutoff frequency ratio. Must be a float value between 0 and 1,
default value is 0.8.
@item min_comp
Set minimum difference between timestamps and audio data (in seconds)
below which no timestamp compensation of either kind is applied.
Default value is @code{FLT_MAX}.
Set the minimum difference between timestamps and audio data (in
seconds) to trigger stretching/squeezing/filling or trimming of the
data to make it match the timestamps. The default is that
stretching/squeezing/filling and trimming is disabled
(@option{min_comp} = @code{FLT_MAX}).
@item min_hard_comp
Set minimum difference between timestamps and audio data (in seconds)
to trigger padding/trimming the data. Must be a non-negative double,
default value is 0.1.
Set the minimum difference between timestamps and audio data (in
seconds) to trigger adding/dropping samples to make it match the
timestamps. This option effectively is a threshold to select between
hard (trim/fill) and soft (squeeze/stretch) compensation. Note that
all compensation is by default disabled through @option{min_comp}.
The default is 0.1.
@item comp_duration
Set duration (in seconds) over which data is stretched/squeezed to
