[Mp4-tech] Query on EAAC+ test streams

[Andreas Schneider]

Hello,
the enhanced aacPlus conformance streams come in three flavours:
- conformance streams for AAC-LC
- conformance streams for SBR
- conformance streams for PS
The first two are available from the FhG ftp-site (
ftp://mpaudconf:adif2mp4@ftp.iis.fhg.de/mpeg4audio-conformance/
compressedMp4/). For AAC and SBR, 3GPP conformance is identical to MPEG 
conformance.
The relevant AAC conformance bitstreams are prefixed alXX, where XX is a 
two-digit number.
The SBR conformance bitstreams are named: al_sbr_*
The 3GPP PS conformance bitstreams don't exist yet. PS conformance in 3GPP 
is currently under discussion.
The effort of defining PS conformance is ongoing within MPEG. Some 
preliminary testbitstreams are in the subdirectory sbr_ps_new/ on the 
abovementioned ftp-site.
For details about conformance testing, please consult:
- ISO/IEC 14496-4:2004 (for AAC-LC)
- ISO/IEC 14496-4:2004/FDAM 8 (for SBR)
Regards,
Andreas
