We have a screening set up to record from singing male songbirds and need a way to continuously record their cages 24/7 but only save files when sound is detected (we have a post-processing step that can then detect song from that set of wav files after). We had been using Sound Analysis Pro 2011 (SAP) for this but it has seemingly spontaneously stopped working on most of our computers so I was wondering if there was any other free software with the same functionality. I saw there was another similar thread but I think they were looking for something to replace different/more complex features of SAP.
Alternatively, if anyone else has had issues (that they were able to resolve) with the SAP recorder suddenly not being able to recognize mic channels on a Dell OptiPlex 7090 please let me know.
But in short what I'm looking for is: Free software that can record from ~8 audio channels simultaneously 24/7, only saving files when sound is detected.
