🎵 Text to Audio Generation with AI

In this video segment, Barry from Music Tech Info introduces a text-to-audio AI project called 'All Audio LDM' on Hugging Face. This project focuses on generating audio from text, including sound effects. Barry demonstrates the process by submitting a description of 'a hammer hitting a wooden surface' and waits for the AI to process and generate the sound, which takes about 36 seconds. He also mentions that the project has a paper and a project page for further exploration. Barry then tries generating other sounds, such as a 'metal cage being thrown about', and discusses community sharing and enhancement tips like using adjectives and random seeds. He explores the potential of the AI for music generation with a description of 'a man singing over a catchy synthwave trap', but finds the result unsatisfactory. He then tries a simpler description, 'Electro pop music', and is pleased with the generated drum beat, suggesting its usability in music production. The video also touches on the technical aspects of the AI, mentioning encoders, diffusion models, and vocoders, and credits Imperial College London and the University of Surrey Guildford for the technology.
