[Mp4-tech] Need BSAC encoded Audio data

[sudeep hegde]

Hi sanjay,
I have listed some of the input options for the bsac encoder and decoder
can you send me a link where bsac streams are available in the iso site and i want to know whether your bsac decoder is working.
regards,
sudeep
Encoding to fl4 (48 kHz mono @ 64 kbits/s)
$MP4AUDVM/mp4auenc -d 1 -m tf -r 64000 -c "-aac_sys_bsac" 
${TESTDIR}/m48.au -o ${TESTDIR}/m48_bsac64.fl4
Encoding to fl4 (48 kHz stereo @ 128 kbits/s)
