Audio restoration is cleaning up a poor-quality audio recording through noise, distortion, or imperfections removal. It is a necessary process widely applied across many industries, from music production to filmmaking and broadcasting. The process traditionally required several expert sound engineers with unique skills and appropriate software. Therefore, this was a time-consuming and labor-intensive process. However, with the involvement of artificial intelligence, this field has a different twist: powerful tools presently automate most of the audio restoration tasks, which are much faster and more available.
Starting in 2024, AI-powered audio restoration has developed greatly by leading machine learning algorithms. The latter allows enhancement and cleaning of audio recordings with unthinkable earlier accuracy.
Such tools also save time and provide an opportunity for professionals and hobbyists alike to create professional results with minimal technical expertise. The following article will outline the most popular AI tools for audio restoration in 2024 by considering their features, use cases, and benefits.
