straycat-rs

A Rust port of straycat, a WORLD-based UTAU resampler

How to use

Download the latest version of straycat-rs and use it like a regular UTAU resampler.

How to compile

Note: By the nature of an UTAU resampler, it is only ideal to build this program in Windows.

1. Install rustup.
2. Decide whether you want to build with the icon.
   • Build with icon:
     1. Install Windows SDK.
     2. Locate rc.exe. It is usually in C:\Program Files (x86)\Windows Kits\10\bin\<version number>\x64\rc.exe
     3. Replace the location for rc.exe in the build script build.rs.
     4. Build with cargo build -r
   • Build without icon:
     1. Delete the build script build.rs.
     2. Build with cargo build -r

I highly encourage building in the other platforms as those builds can be used in OpenUtau. Build steps for Mac/Linux should be similar, just follow build without icon skipping step 1.

Remarks

This resampler will not be an exact copy of straycat, but a variation of it. It may not do the exact same things as straycat, but my goal with this resampler is to match or surpass the quality of straycat.

I am also not obliged to transfer the flags from straycat to straycat-rs, but if I do, I will most likely add improvements to it to give the users a better experience.

Overall, this resampler serves to be a new and improved version of the older Python-based straycat, not a faithful translation of straycat to a compiled language.
