SoX recording audio and trimming silence

Records audio from your mic in FLAC (Free Lossless Audio Codec) format, starts only after it detects at least 0.1 seconds of noise and stops after 1 second of silence. You can adjust the percent values (sensitivity) to best fit your microphone and voice (0.1% if you have a great quality mic, higher if you don't, 0% does not trim anything).

Useful for speech recognition in conjunction with my previous command titled 'Google voice recognition "API"' (http://www.commandlinefu.com/commands/view/8043/google-voice-recognition-api).

What others think

Hello, this works perfectly for actually recording the audio, although the recorded flac does not end up being readable by the Google Voice recognition API. I did have to change "alsa" with "waveaudio". Any ideas would be much appreciated. I tried going through the SOX documentation and trying various things, but nothing worked.

Thank you.
