Définition
Audio signal processing underlies speech recognition, noise reduction, sound classification, music generation, recording enhancement, and audio analytics. AI models use sound cues, frequencies, spectrograms, pauses, rhythm and timbre to understand or modify audio.
Exemple
The podcast service removes background noise, equalizes volume, and improves voice intelligibility.
Pourquoi c'est important
The term is important for users who are looking for tools for audio: transcription, recording cleaning, editing, music or call analysis.

The sound is converted into a digital signal, split into fragments, frequencies and features are analyzed, and then filters, models or transformations are applied.
Où c'est utilisé
- noise reduction
- transcription
- call and music analysis
Limites
A bad recording limits the results. High noise, echo, aliasing and low sampling rates can degrade the quality of even a good model.
