Nice use of local AI!

It sure does.

thx!

A fun project I'm working on: Chipmunkify. You upload a song and it isolates the vocals to give you a 'chipmunk' version while keeping the instrumentals untouched.

Have fun trying it and let me know what you think!

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?

stack was mainly vite (react) + typescript pretty much (canvas 2d for the visuals)

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.

Chipmunk'd versions of songs on Youtube: https://www.youtube.com/@ChipmunkEstudio Taking song requests!

Reminds me of the classic Sludgefest [0]. (For the uninitiated it's a collection of Chipmunks records slowed until the voices sound roughly human.)

Neato!
