From the developer:
The purpose of this little sine wave generator is to generate a clear sine wave on both channels that will be phase locked. So you can measure the phase shifts between different frequencies on your soundcard. But of course you can use it for many other purposes.
One of the biggest advantages of Little SineGen is that it can process at any sampling rate your soundcard can handle. To use Little SineGen just select your soundcard.
