It sure does.

thx!

Hi HN,

You know those YouTube channels with millions of views that are just popular songs, but chipmunk? They sound awful because they pitch-shift the entire track.

I fixed it.

The pipeline: Upload an MP3 -> Demucs isolates the vocals -> Rubber Band pitch-shifts them into the rodent register -> FFmpeg glues it back together. Hosted on Modal.

Guardrails protecting my $5/month Modal budget and net worth:

* 10MB max upload

* First 30 seconds only (Demucs is computationally brutal)

* 3 requests/IP/day

I delete your files immediately out of principle, but also because I genuinely cannot afford to store them.

If the site throws an error, you've assassinated my budget and I will pour one out.

Try it out and let me know what you think. I suggest using a song that you love!

This is great, thanks for sharing.

I like the concept! What tools did you use to build it?

Not surprised. It takes obsessive focus to make a startup successful, especially in an industry so saturated with talent.

Leave every place you visit better than you found it. Example: pick up trash in public spaces such as parks and restrooms.

Neato!
