Infrasound and ultrasonic are not important for music recordings. AFIK bats produce sound up to 200 KHz, so 192 KHz anyway can't do the job. A former girl friend did bat research :), but we never talked about bat audio, just about bat behaviour :), so I only have "Wiki" knowledge about bat's audio abilities and this might be wrong. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
