Ask HN: Audio analysis models, how to train to learn sound patters?

Hello all, I'm looking to for sound models that understand sound patters that can be used locally. Hoping I can use them on device like iOS CoreML. Before I get started it doesn't hurt to ask to see if anyone has done this before or has a sound model that detects patters, Anger, excitement, Arousal, laughing, crying, laughing, human emotions in general. I found this :https://medium.com/@narner/classification-of-sound-files-on-ios-with-the-soundanalysis-framework-and-esc-10-coreml-model-3a5154db903f https://medium.com/@narner/classification-of-sound-files-on-... But maybe there is a better way or something already exists. Thanks
