I have some need to Covert an 8 Bit PCM Wave Sound (Mono) into a Compressed
GSM Sound. I am Reading from Microphone as above Wave Format, and want to
convert this sound into GSM. I know that If I use "GSM610WAVEFORMAT" to
Read, the device itself will return GSM compressed sound. But, I don't know
how to convert it after recording as wave.
