[M4IF Technotes] Re: mpeg-4 AAC conformance bit-streams

Thu May 2 21:47:12 EDT 2002

Dear Anil, all,
sorry for any inconvenience. There is an "f" missing at the end of the accont name. The link is actually:
ftp://mpaudconf:[email protected]/guests/mpeg4audio/incoming/testSequences/mpeg4audio-conformance/
The subdirectory compressedMp4 contains the compressed data in mp4 file format.
The subdirectory referenceWavZip contains the uncompressed but ziped waveforms in 24 bit resolution.
Best regards,
Ralph

The error-resilience code is available in the subdirectory aacErrRobTrans (encoding part) and in the subdirectory mp4AudVm (decoding part). The low delay AAC code is available in the subdirectory mp4AudVm (encoding and decoding part).
