Transformers.js/Audio Classification
Hugging Face Machine Learning Directly in the Browser
Transformers.js enables running Hugging Face state-of-the-art pretrained transformer models (BERT, Whisper, CLIP, ResNet, DistilBART) natively in browser using ONNX Runtime Web.
Audio Classification
Classify acoustic events, environmental sounds, and speech emotion categories using AST (Audio Spectrogram Transformer).
Audio Classification implementation using Transformers.js.
Provides instant interactive Audio Classification capability directly inside browser.
In: Audio Track or File
Out: Transcribed Text / Audio Tensor
Implement browser-side Audio Classification without cloud API latency.
Interactive Laboratory: Audio Classification
Target Engine: Transformers.js
Upload audio file (WAV, MP3, OGG, FLAC)

Code Used for this Demonstration
Actual code pattern that will be invoked when running this capability in production with Transformers.js:
import { pipeline } from '@huggingface/transformers';
const classifier = await pipeline('audio-classification', 'Xenova/ast-finetuned-audioset-10-10-0.4593');
const results = await classifier(audioSource, { topk: 5 });
console.log(results);How It Works: Processing Pipeline
