-        "[YAMNet](https://github.com/tensorflow/models/tree/master/research/audioset/yamnet) is a pre-trained neural network that employs the [MobileNetV1](https://arxiv.org/abs/1704.04861) depthwise-separable convolution architecture. It can use an audio waveform as input and make independent predictions for each of the 521 audio events from the [AudioSet](http://g.co/audioset) corpus.\n",
