I'm trying to find a way of automatically identifying birdsong in phone-recorded sound files (1min long). Currently the algorithm I'm using doesn't label all of the events I want it to. (it is designed for non noisy audio files).
I don't have much experience in DSP. I'm hoping that upon looking at my wave-forms someone may have an idea of how to pick out these 'birdsong events'! I've shown one of the waveforms. The rest can be seen here: imgur.com
Any method would be appreciated!
I've thought about applying a noise reduction algorithm but I suspect this could just interfere with things. Here is a link to the algorithm I'm using in case you're interested: Github/kylemcdonald
Thanks in advance for taking the time to look at this!
