SYNOPSIS

-resolution int: Set the sample resolution. Must be 16 or 32, but not all values are supported by all sound srivers.
-device string: Sets the audio device. This also automatically select the sound driver. Devices names starting with "/dev/" use the OSS driver and names starting with "plughw:" use the ALSA 0.9 driver. Some drivers may not be available on your system.
-soundcard: Select the soundcard as input.
-diskfile: Select a diskfile as input. Use the option filename to specify the name of the file.
