Hi everyone,

I'm a neuroscientist working in language and speech. I work in songbirds, and I am trying to adapt a Pi to recognize birdsong and activate the delivery of food reward in response to song. I purchased your stereo soundcard, and while I could get to record sound properly on the Pi with alsa, I encountered issues with the script found at this page: https://www.bishoph.org/

It's a sound recognition script. When setting it up, it indicates to run 

python sopare.py -u
python test/test_audio.py

this should return a threshold that is based on the ambient noise. It should be around 100-300. I get 32000. I tried troubleshooting, I purchased another USB microphone that has a crappy background noise, and still the threshold is about 1000 and I get the bishoph script to run properly (not all the way through though, as it lacks specificity, and I am afraid that it's due to the crappy recording conditions). Your soundcard's microphone records very well, and therefore I would like to use that one with the script. 
I am writing to you to ask for "product support" for your stereo soundcard, as I am afraid there is something obvious that I am missing due to my noob-ness with programming and Pis. What could be the source of this super-high threshold?
I tried decreasing the microphone input volume, no change.
I tried setting the threshold at a lower level despite the indications, but the script reads a continuous input of sound through the microphone even if there is no sound (consistent with the idea that I set the threshold lower than what the bishoph script suggested)
I tried setting the threshold at the indicated level, but even if I shout in the microphone it doesn't pick up anything, as the threshold is so high.
However, I can record with alsa and I get great recordings! It's just something at the level of the cross-talk between the sound card and the script. I tried asking the script admin, but he said that it appears that it's a problem with the sound card.

Can anyone please help me?

Thanks!

Massimo
