Use 8-bit mode instead of the default 16-bit mode.
-a [card_num:]dev_num
The card and device number to record from.
-b size
The sample size; one of 8, 16, or 32.
-c hw_channel_bitmask[,hw_channel_bitmask...]
Voice matrix configuration. The first argument is the hardware channel bitmask for application voice 1, the second is that for application voice 2, and so on, up to four voices.
-f frag_size
The requested fragment size.
Record in mono instead of in stereo.
-n num_voices
The number of voices to record. The default is 2 (stereo).
-r rate
The rate at which to record; one of 48000, 44100 (the default), 22050, or 11025.
-t sec
The number of seconds to record (5 seconds default).
Be verbose.
Use the mmap plugins.
Note: If you specify both the -m and -n options, the one specified later is used.


The waverec utility captures (i.e., records) audio data.
