qarecord 0.5.0-0ubuntu8 (i386 binary) in ubuntu focal

 QARecord is a simple but solid recording tool. It works well with stereo
 and multichannel recordings, supporting ALSA and JACK interfaces and in
 both 16 bit and 32 bit mode. By using a large ringbuffer for the captured
 data, buffer overruns are avoided. It has a Qt based GUI with graphical
 peak meters.
