Decrackle

Upload audio or video to Decrackle and you get back cleaned-up sound, a transcript, and analysis of what was said.

Decrackle is an AI audio enhancer and transcription platform for audio-visual content creation and conversation intelligence, and it also covers captions, summaries and sentiment analysis.

It is listed under AI API as well, so developers can look at it as a building block and not only a web app.
