how do you mean that? 28.8kbps is no bandwidth, though it may use one...

have you tried that? without a good compression/decompression algorithm?
simple 8bit sampling at, say, 4ksps (which gives an upper limit of 2kHz)
makes for 32kbps. so in order to understand something with only 8kbps, you
have to employ some serious compression (which in a short term average has
a min. 4:1 ratio). not impossible, but maybe not so easy either (for a PIC
in a handheld=low power device).
