If you go to export and choose | audiogram, it will convert the audio/video you uploaded to text | and create an audiogram. | nmstoker wrote: | I had ended up using ffmpeg a few times for this (i think | inspired by the link you gave there) because it's often easier | to share video than just audio on mainstream social media | | A few details of what worked for me and the output shown here: | | https://discourse.mozilla.org/t/tts-audio-to-video-trick-usi... | | But Astrofox looks much cooler and massively more | sophisticated. | kebman wrote: | Slightly reminiscent of old school demo scene stuff.

I'd love to | find a piece of software that could be selected as the sole | output for either a system's audio or a specific application, | keep a buffer of the audio stream for processing, create an AV | output, and then allow that to either be captured or streamed to | something like OBS or VLC. Realistically, I can see latency being | a bit of an issue of course. Audio fidelity may also take a hit | if you exceed the buffer's capacity, but trying to implement a | direct passthrough for the audio may desync the it from the | visualizer. | | Maybe it's just a pipe dream, but has anyone created/worked with | a project like that before? I'd be interested in seeing what's | out there. | Cyberdog wrote: | Streams, a pipe dream? I see what you did there. | | Unfortunately this appears to be an Electron app, so expecting | behavior which would probably be quite simple for a real | application does in fact seem unlikely. | | Too bad, too, since this does indeed look like a cool app. | jalino23 wrote: | I love this so much! I've always wanted to build one. but | struggle with the math to turn music frequency into something | beautiful visually | nikolay wrote: | The latest version seems broken. It's not available on Homebrew | either. | BizarroLand wrote: | Could be a useful tool to generate snippets for a larger project. | TedDoesntTalk wrote: | Is there a package like this that renders real-time rather than | to a video for sharing? (like winamp visualizations used to do) ___________________________________________________________________ (page generated 2022-07-07 23:00 UTC)
