I’m on iOS too. From experience it’s usually because the video container, codec, or options, you are using for the video is not supported by iOS. In your case I see you are using a webm container. iOS prior to version 15 does not support webm natively. Then earlier this year they started adding support for parts of webm in iOS 15. https://9to5mac.com/2021/08/10/apple-adding-webm-audio-codec... I recommend converting…

I’m on the latest version of iOS (15.1.1) and it doesn’t load for me either. Perhaps the server hosting the video file is overloaded?

My comment originally only said that webm was not supported prior to iOS 15. But webm videos are not fully supported in iOS 15 either afaik, so I updated the comment to specify that they started adding support for parts of it. You may have seen an earlier version of my comment without that qualifier, in which case I apologize for any confusion.

The demo here is underwhelming compared to old-school winamp visualizers. But I think that with deep learning, there is now a real opportunity to make a kickass visualizer. Take a GAN and set the latent vector according to the DFT of the audio stream -- it would be super trippy. You could even use WaveNet and CLIP to make the visuals match the lyrics.

Yeah, I can understand that.

I had a lot of fun listening to music in winamp when I was younger with milkdrop. But I think my tastes have changed now to where I prefer visualizations with more concrete imagery and variety instead of the usual variations of abstract effects (they are still dope as hell though).

I tried to design this app with that in mind, but I definitely see why some people don't find them this style of visualization to be interesting. Maybe someday someone will put some serious effort into bringing the demoscene-style visualizations into the modern era?

I do have a twitter video available (no youtube unfortunately, sorry!) https://twitter.com/hyperchroma/status/1464656712544174083 I'm not sure if the trailer loading is an issue on the site - could you check the console for me and see what it says?

Ah, thank you very much!

Just gave this a whirl and it's pretty neat! Some feedback:

- App looks very pretty. Highlights are the subtle animations when scrolling long lists in the Library, and using album art in individual rows.

- I like the output of the visualizer. The glitch transition between tracks looks great.

- Having the visualizer in the background while browsing music is a bit distracting.

- Definitely needs some default imagery for the visualizer, I expected it to work out of the box.

- Took a really long time to index my music collection (about 20 minutes for metadata and another 5 minutes to generate thumbnails). This is for 81,000 songs w/ a high-end desktop computer.

- Under library > artist, `Unknown Artist` has almost all albums attributed to it. Most of my collection is MP3 with ID3v2.4 tags (artist field always populated, album artist populated when applicable). In Hyperchroma, most artists are listed with the correct number of songs, but 0 albums.

Probably not what you're after, but I think this could be very successful as a free/cheap alternative to After Effects specifically to generate the music videos. (rather than a music player)

The trailer contains footage of the music videos produced (the part with the fancy effects and transitions synchronized with the music). It's basically a real-time video that plays within the app alongside your music - it doesn't output videos as files. I need to probably make that part clearer somehow.

> it doesn't output videos as files Er, might I ask why not? Be a lot cooler if it did...

Yeah, it would be pretty cool.

I think the main reason is that the visualizations are driven by audio analysis, which is often inferior to actual videos edited by hand. This isn't designed to compete with videos made by people, only to provide a good-enough substitute.

I could implement a video editor to let people have more control over the visualizations, but people can already use existing video editors to do that instead if they really wanted to. So I decided that it wasn't worth the effort.

Thank you for the detailed feedback!

Some of the stuff you mentioned are definitely bugs. Do you mind submitting them to the issue tracker?

Hey,

Just wanted to let you know that the issue should be resolved now. Apologies for the inconvenience.

Are you talking about the anime girl? If so, does it do other things or just anime girls?

You can use whatever images you want. You load your images into the app along with your audio and it uses those images. There's a bunch of effects like filters, transitions, particles, etc. that you can customize to adjust the visualizations.

I guess what I'd really like to see is a demo of the different effects and filters and whatnot. Nothing extreme, but show how they can make the same pictures into a different experience.
