introduction

snibbetracker is a fakebit tracker written in C using SDL2 that I began working on in 2014 to learn DSP programming. As I do not have time to work on it anymore, I decided to release the source so that someone could take over if they wanted.

config

buffer setting:

Use lower values to decrease latency, higher values to avoid stuttering if the buffering cannot keep up. Needs to be a power of two, for example: 256, 512, 1024, 2048, 4096, 8192.

"buffer_size":4096

Path to working directory, needs to be full. OSX example: /Users/d/Documents/snibbetracker Windows example C:\snibbetracker Make sure that the folder exists before using it and that is is accessible by the program.

  • edit cursor disconnected from player cursor. (can be toggled with modifier+F)
  • directory browsing completely disabled for saving and loading files, only uses the directory the exe is in. when loading files, just type the name without the .json and press enter, same as for saving.

build 5

  • test release.
You can’t perform that action at this time.
