[M4IF Technotes] CELP test files or encoder?

[Ralph Sperschneider]

Hi Ben,
you will find mp4 files with MPEG-4 CELP content on the conformance MPEG-4 Audio 
ftp server:
ftp://mpaudconf:adif2mp4@ftp.iis.fhg.de/mpeg4audio-conformance/compressedMp4/
All files starting with 'ce' contain CELP data in various configurations.
Beside this, the current MPEG-4 reference software (ISO/IEC 14496-5:2001) should 
be able to produce CELP content.
Best regards,
Ralph
