Hi,

We are developing HE-AAC-V1 decoder which decodes files with 960 frame length. For SBR conformance test, i found input files. But i couldn't find any reference output files. Input files location: ftp://mpaudconf:adif2mp4@ftp.iis.fhg.de/m.../compressedMp4/
can someone let me know where can i find the reference output files or reference decoder(HE-AAC-V1 or HE-AAC-V2) which decodes 960 frame length files.

Thanks,

Sana

Doesn't the MPEG reference code do that?

I think Reference code supports only 1024 frame length not 960 frame length.

Test sequence for 960 frame length SBR conformance test is given in this document "ISO/IEC JTC 1/SC 29/WG 11/N10397". But no reference output files are given. Can anyone let me know where can i find the reference output files?

For SBR tests there are no reference output files, you have to use the "sbrconftool", see MPEG-4 part 4 (or 26). I've never used it, though, so I have no experience with it.
