Description: implent raw sound record/play
run: ./SndKit [-h] [-d device] [-c channel] [-b bits] [-f hz] [-l len] <-r|-p file>
e.g.:
./SndKit -h show help information
./SndKit -r record.wav record audio from microphone(/dev/dsp)
./SndKit -d /dev/dsp -p record.wav playback record.wav via /dev/dsp
./SndKit -b 8 -f 22 -r reacord.wav record audio in 8 bit & 22k hz
./SndKit -d /dev/dsp -c 2 -r record.wav record audio in /dev/dsp and stereo
./SndKit -r -l 40 record.wav record 40k audio data
