ADPCM Coder/Decoder |
|
|
Hi, I need some technical information. I would like to know if you can
supply us a software that can make a ADPCM or LPC coding and that is
implementable on a 16 bit microcontroller.
Our aim is to realize a voice board that can record up to 8 minutes time on
static ram. So we suppose compress an voice stream to maximun 16 Kbit/sec.
thanks

Fabio,
First, I don't know what is your quality goal however the ADPCM at
16kbit/s sounds very lousy. The lowest MIPS codec with the reasonable
quality at the bitrate below 16kbit/s is GSM 6.10. We can build one for
your CPU. My email is given at the website below:

In which case, low audio quality may be a desirable result.
The ADPCM spec is available on the Freescale (nee Motorola) website

Reference code for ADPCM codec can be found as part of the MiBench benchmark. This is a well-known benchmark suite, frequently used in papers.
search for MiBench in google
