- Recording sound output of a program:
- Many onboard card offer a 'vol' mixer control. If this is used as a recording source, than the current sound output will be recorded. Note that this is the mixed total of all sound played, not of a single program.
- ossrecord -ivol blah.wav
- vmix loopback driver can record the output of a program. Set vmix_numloops to 1 (or more) in vmix.conf, and make the program output to the newly created /dev/oss/vmix0/loop0 device. Than record from that device. e.g.
- ossplay test.wav -d/dev/oss/vmix0/loop0 &
- ossrecord test2.wav -d/dev/oss/vmix0/loop0
- OSS wrappers can be used to record the output of a program. vsound is one such wrapper. (vsound can't handle output to /dev/oss/* device nodes).
- vsound ossplay test.wav
