[M4IF Technotes] MPEG-4 CELP Voice Codec (Was MPEG-4 Audio - related to GSM-AMR)

[Arcin Bozkurt]

Thanks everyone replying to my email about MPEG-4 Visual + GSM-AMR.
Possible options suggested include:
- use ASF (Microsoft) format for streaming
- 3GPP Packet-Switched Streaming specification
- Signal AMR as a "non-MPEG" stream via a 3rd party registration
authority (work is still going on in MPEG Audio Work Group)
We will continue investigating these for the future.

For the time being, we decided to use MPEG-4 Celp Vocoder.
I am looking for an ARM-9 optimized MPEG-4 CELP codec? Do you know of
any such codecs? 
Thank you very much.
