This can be useful for tuning a sub/sat speaker -system. It is intended for use a dtas-player sink command as displayed -in the synopsis. - -The INPUT arguments (/dev/fd/lo and /dev/fd/hi) are automatically -changed by dtas-player to match the given file descriptors of the pipes. - -Both descriptors receive the same audio data, but will be split using a -Linkwitz-Riley crossover.
