Meta's open-source MusicGen AI uses text to create song genre mashups

Meta's Audiocraft research team has just released MusicGen, an open source deep learning language model that can generate new music based on text prompts and even be aligned to an existing song, The Decoder reported. It's much like ChatGPT for audio, letting you describe the style of music you want, drop in an existing tune (optionally) and then clicking "Generate." After a good chunk of time (around 160 seconds in my case), it spits out a short piece of all-new music based on your text prompts and melody. The demo on Facebook's Hugging Face AI site lets you describe your music, providing a handful of examples like "an 80s driving pop song with heavy drums and synth pads in the background." You can then "condition" that on a given song up top 30 seconds long, with controls letting select a specific portion of that.
