The files you're trying to replace should be sound/ui/hitsound.wav and sound/ui/killsound.wav if you're using the default hitsound and killsound. If you don't see any error messages then you got the file path wrong. On 07-Jul-21 12:28, davidak wrote: Here is an Audacity fork that adds support for building 64-bit Windows binaries. Make sure that the project rate in the lower left-hand corner of Audacity says one of those numbers before exporting (higher is better in most cases). Audacity builds fine now (after the Cmake port) in 64-bit mode the issue is more around testing and making sure there isnt some major new bug lurking out there. If you see messages in console about "invalid sample rate" then that means your sound isn't at one of the sample rates that Source uses (44100 Hz, 22050 Hz, 11025 Hz).
