A sample rate and beats-per-minute calculator for music production. It run on Windows and Linux and is written in C++. It was originally released on http://zetacentauri.com and was downloaded more than 20,000 times before being open-sourced.
A prebuilt installer for Windows is available in the installer folder:
https://github.com/Xangis/SampleRate/blob/master/installer/SampleRate1.02Setup.exe

To calculate the semitone shift from one sample rate or BPM to another, fill in the first two blanks and then click "Calc" next to the Semitone Shift text box.
To calculate the sample rate or BPM change to alter audio by a specific number of semitones, fill in the first blank, enter the semitone shift, and then click "Calc" next to the End Sample Rate/BPM text box.
Building requires that wxWidgets be installed (3.0 recommended, but older versions should also work).
There is a Makefile included for use on Linux. If your wx-config is in a different location than that in the Makefile, change the path in the Makefile.
To get the required wxWidgets development libraries on an Ubuntu or Debian-based system, run:
sudo apt-get install libwxgtk3.0-dev
To get wxWidgets for Windows, download it here:
http://wxwidgets.org/downloads/
There is a Visual Studio project included as PixelSwapper.sln. However, you'll need to edit the "Additional Library Directories" and "Additional Include Directories" paths in the project settings to point to where wxWidgets is on your system.
If it complains about not finding "wx/wx.h", then you need to set the include path.
If it complains about a bunch of "unresolved external symbols" starting with wx, then you need to set the library path.
There is an InnoSetup installer script in the installer directory. You'll need to edit it to match the paths where your project is located since they are all absolute paths.
You can get InnoSetup here:

Changes in version 1.02:
- First open-source version.
- wxWidgets libraries updated from 2.8 to 3.0.
- Visual Studio redistributable is included in the installer for users who don't have it yet.
I consider this application to be finished and it is no longer under active development.
I do still maintain it and will update it as operating systems evolve.
