Audio classification answers "what is this noise?" rather than "what words were said". Audio Spectrogram Transformer models tagged on AudioSet recognise hundreds of everyday sound events — speech, music, engines, alarms, animals — while Wav2Vec2 keyword-spotting models handle short spoken commands. Record or upload a clip and you get ranked labels with confidence scores, computed locally.
No. These models recognise categories of sound, not individual recordings — they will tell you "music, guitar, singing", not the track title. Audio fingerprinting is a different technology.
What audio format should I use?
Anything your browser can decode: WAV, MP3, M4A, OGG, FLAC. The page resamples to the 16 kHz mono the models expect.
