What are some good learning resources on audio processing, detection and anomaly detection using machine learning or deep learning? I am interested in machine predictive maintenance using audio anomaly detection

See this book and the sources it links to: https://musicinformationretrieval.com/ Also google for pitch and onset detection. If you want more specific help, you have to ask a more specific question.

Here's a resource that breaks down the various audio processing tasks and provides case studies: https://www.analyticsvidhya.com/blog/2018/01/10-audio-proces...

It's slightly academic so here's a more practical resource: https://towardsdatascience.com/audio-classification-using-fa...

Just found this thread on the fast.ai forum yesterday that may help: https://forums.fast.ai/t/deep-learning-with-audio-thread/381...

There's a good class at UIUC regarding signal processing:

Course is led by Paris Smaragdis, one of top researchers in the field of audio processing.

It sounds as if he's looking for tools that can be used to monitor the sounds coming from machinery to detect or predict impending failures. I found your link interesting since I'm interested in musical applications of machine learning, but I don't think it's what he's looking for.

aubio and librosa are two excellent MIR (music information retrieval) tools I can recommend from personal use. They can both be implemented for real-time audio using pyaudio or similar.
