These samples have been edited from Shiru's recordings.
Originals can be found here:

Original samples can edited and used separately from the Flopster VSTi under the

Installation instructions
- Currently these samples need to be manually copied to the 86box executable path under '/samples'
or to the same directory with 86box executable.
- The samples are 48kHz 16bit 1 channel PCM WAVE samples. Immersive86box code does not make any resampling,
and assumes that the host audio system is using 48kHz 16bit output.
