Hi Alsa Experts! I use a software package called Kaleidoscope Lite to analyse bat calls. Part of the fun is using their audio playback feature to replay sounds from a .WAV file at frequencies humans can hear. This typically involves division of (say) a factor of 10 as the bat call is in the range 20kHz up to 100kHz (very roughly). I would like to save these snippets of sound [as they are played after frequency reduction] to separate files for audio playback and have submitted a feature request. But it struck me that it might be possible to capture the sound in some other way. Hence this post. I am running Kaleidoscope Lite 5.6.3 (latest stable) on Linux (Ubuntu 22.04.3) using the aoss script to wrap the call to the product.
