-// More potential compressor algorithms:
-// Use single reaction time parameter. Negative reaction time uses
-// readahead. Positive reaction time uses slope.
-
-// Smooth input stage if readahead.
-// Determine slope from current smoothed sample to every sample in readahead area.
-// Once highest slope is found, count of number of samples remaining until it is
-// reached. Only search after this count for the next highest slope.
-// Use highest slope to determine smoothed value.
-
-// Smooth input stage if not readahead.
-// For every sample, calculate slope needed to reach current sample from
-// current smoothed value in the reaction time. If higher than current slope,
-// make it the current slope and count number of samples remaining until it is
-// reached. If this count is met and no higher slopes are found, base slope
-// on current sample when count is met.
-
-// Gain stage.
-// For every sample, calculate gain from smoothed input value.
