Description
AE.< port > CHFMT Dual, Mono,
Stereo, Jstereo
Stereo Compressed audio format ; determines how the
SE4000 will compress the audio channels.
? 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.
? 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.
