Thanks to those reply my email.

The simplest solution for you is ADPCM (can be as low as 2-bit per sample)
To get better compression you can use time scale modification like TDHS.
I'm not sure if the 33MHz ARM can run recent codecs with performance requirements.
Also most recent codecs use analysis-by- sinthesis method,
so the encoder and decoder performances are quite the same.
