If you mean to give a source of melody of 30sec and extend that melody into a full song, yes MusicGen can do that. There are two ways to extend a song based on a melody: 1) give a sample, and continue the song from that sample as close as possible, and 2) give a melody as an inspiration. They both work in varying degrees of success. Audiocraft on github, issues or discussion sections have a lot of questions answered.

Evidence? None of the demos suggest that is true.

  Did they change the base model? If not, then the audiocraft_plus, is based on audiocraft, and it creates music of length close to 5 minutes. I don't know if audiocraft_plus incorporates all three modalities of the release, MusicGen, AudioGen, and EnCodec. It uses MusicGen for sure, all four models, small, medium, large and melody. https://github.com/GrandaddyShmax/audiocraft_plus https://github.com/GrandaddyShmax/audiocraft_plus

    Bit is that "extension" to 5mkns more than just the repeat of e.g. 15secs heard in the demos?

      Yes, of course it is more than that. You can create full songs of several minutes. I have published 20 songs on youtube of 2-3 minutes each. Listen to that song, the best i have made so far [1]. It doesn't repeat at all! I haven't looked closely to this release, is the audiocraft page on github different than facebookresearch/audiocraft? The other two modalities may be new, AudioGen, and EnCodec, but i was under the impression that they changed the license to full open source, and that was that. https://www.youtube.com/watch?v=UL1KmrHMjcM https://www.youtube.com/watch?v=UL1KmrHMjcM

        Thanks. What I hear there is 19s of material on repeat, with the parallel parts variously brought in and out, and no other variation except in decorative detail. So yes not a literal repeat, but no not enough to rate as a "full song", IMO. Plus it is not actually song at all, note. Singing would particularly expose its repeat-and-vary trick.
