I have just started: arecord -B 1000000 -F 500000 -c 1 -r 44100 -f S16 -M -D hw:0,0 -v arec.wav
It gave a file size of 258822944 bytes. Almost 50 min: echo "258822944/(2*60*44100)" | bc -ql 48.90
This is the longest recording I have made on this hardware.
I have this running now: + arecord -B 200000 -F 100000 -c 1 -r 44100 -f S16 -M -D hw:0,0 -v arec.wav Recording WAVE 'arec.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono Hardware PCM card 0 'SiS7019' device 0 subdevice 0 Its setup is: stream : CAPTURE access : MMAP_INTERLEAVED format : S16_LE subformat : STD channels : 1 rate : 44100 exact rate : 44100 (44100/1) msbits : 16 buffer_size : 8820 period_size : 4410 period_time : 100000 tick_time : 0 tstamp_mode : NONE period_step : 1 sleep_min : 0 avail_min : 4410 xfer_align : 4410 start_threshold : 1 stop_threshold : 8820 silence_threshold: 0 silence_size : 0 boundary : 1244678400
