The video introduces four groundbreaking AI audio tools that are available for free and can be run locally on a computer without an internet connection. The first tool, Audacity, offers AI plugins for audio enhancement, including transcription, noise suppression, and stem separation. The transcription plugin uses OpenAI’s Whisper model to transcribe audio files accurately and quickly. The noise suppression tool effectively removes background noise, and the stem separation feature allows users to isolate vocals and instruments from music tracks. Additionally, the video showcases AI-powered music generation, which can remix existing tracks or create new music based on text prompts. The presenter demonstrates the installation and use of these tools, highlighting their potential for audio editing and creation.
