Stereo
Compressed audio format ; determines how the
HE4000 will compress the audio channels.
● Stereo – left and right audio channels are
compressed separately into two output waveforms.
Stereo uses more bandwidth than mono; however,
if the input audio source is stereo, the stereo effect
will appear at the output audio device.
● Jstereo – the left and right audio channels are
compressed jointly into two output waveforms.
Jstereo uses more bandwidth than mono but less
than stereo and dual. Use Jstereo when the left
and right audio channel inputs are highly
correlated (i.e., left and right stereo channels of
one audio program source). The similarities
between the two channels are used, saving
bandwidth without losing the stereo effect at the
output device.
● Dual – left and right audio channels are
compressed separately into two output
waveforms. Use dual when the left and right
audio channel inputs represent separate and
independent audio signals.
● Mono – during audio compression the right
audio channel input is ignored and a single
output waveform is produced based on the left
channel input. Mono uses half the bit rate of
dual; however, if the input audio source is
stereo, the stereo effect at the output audio
device will be lost.
