A deep learning model that classifies sounds in 10-second audio clips into 527 categories from the AudioSet ontology.
IBM MAX Audio Classifier is a deep learning model that identifies and classifies sounds within 10-second audio clips. It uses a multi-attention classifier trained on the Google AudioSet dataset to predict the top five sound categories from a vocabulary of 527 labels, such as music, speech, rain, or thunder. The model solves the problem of automated audio event detection, converting raw audio into structured semantic labels.
Developers and researchers building applications that require automated sound recognition, such as content moderation systems, multimedia indexing tools, smart home devices, or audio analysis pipelines.
Developers choose this model because it provides a production-ready, pre-trained audio classifier that can be easily deployed via Docker, eliminating the need to collect massive datasets or train complex models from scratch. Its integration into the IBM MAX ecosystem ensures reliable performance and straightforward API access.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Comes fully trained on the extensive Google AudioSet dataset, ready for deployment without additional training, as mentioned in the README under Model Metadata.
Packaged as a Docker container with a REST API and Swagger UI, making it easy to deploy locally, on cloud, or Kubernetes, as outlined in the Deployment options section.
Recognizes 527 distinct sound classes from the AudioSet ontology, covering music, speech, and environmental noises, providing versatility for various audio analysis tasks.
Uses a multi-level attention mechanism for weakly supervised audio classification, improving accuracy as described in the referenced papers and model description.
Only processes 10-second audio clips; longer files are clipped, and shorter ones are repeated, which can distort context for sounds that develop over time, as noted in the Use the Model section.
The README admits the model performs best for Music/Speech categories due to bias in the training data (90% of AudioSet), reducing accuracy for less common sounds like environmental noises.
Requires 8GB Memory, 4 CPUs, and AVX support, making it unsuitable for lightweight deployments or older hardware, as stated in the Pre-requisites.
Lacks built-in mechanisms for fine-tuning or adding custom sound categories; users are limited to the pre-trained 527 classes without extensive retraining efforts.
