compressed.
stereo, the stereo effect will appear at the
output audio device.
● Dual Mono – the left and right audio channels
are compressed separately into two output
waveforms. This option uses more bandwidth
than mono, however, use this option when the
left and right audio channel inputs represent
separate and independent audio signals.
● Joint Stereo – the left and right audio channels
are compressed jointly into two output
waveforms. This option uses more bandwidth
than mono but less than the stereo and dual
mono options. Use this option when the left and
right audio channel inputs are highly correlated
(i.e., left and right stereo channels of one audio
program source). The HE4000 uses the
similarities between the two channels to save
bandwidth without losing the stereo effect at the
output audio device.
● Mono – during audio compression the HE4000
ignores the right audio channel input and
produces a single output waveform based on
the left channel input. This option saves
bandwidth; however, if the input audio source is
stereo, the stereo effect at the output audio
device will be lost.
