SoundTouch Sound Processing Library is an open-source audio processing library for changing the Tempo, Pitch and Playback Rates of audio streams or files:
- Tempo (time-stretch): Changes the sound to play at faster or slower speed than original, without affecting the sound pitch.
- Pitch (key) : Changes the sound pitch or key, without affecting the sound tempo or speed.
- Playback Rate : Changes both the sound tempo and pitch, as if an LP disc was played at wrong RPM rate.
Main features:
- Easy-to-use implementation of time-stretch, pitch-shift and sample rate transposing routines.
- High-performance object-oriented C++ implementation.
- Full source codes available for both the SoundTouch library and the example application.
- Clear and easy-to-use programming interface via a single C++ class.
- Supported audio data format : 16Bit integer or 32bit floating point PCM mono/stereo
- Capable of real-time audio stream processing:
- input/output latency max. ~ 100 ms.
- Processing 44.1kHz/16bit stereo sound in realtime requires a 133 Mhz Intel Pentium processor or better.
- Platform-independent implementation: The SoundTouch library can be compiled for any processor and OS platform supporting GNU C compiler (gcc) or Visual Studio, for example Win32, Linux, AIX.
- Additional assembler-level and Intel-MMX instruction set optimizations for Intel x86 compatible processors (Win32 & Linux platforms), offering several times increase in the processing performance.
- Compiled executable binaries available for Windows.

PayPal Wifi PrePaid integrates with Chillispot and FreeRADIUS and PayPal. PayPal Wifi PrePaid allows the customer to choose how much time they wish to purchase, processes the payment with PayPal, then creates their username and password automatically, and updates the SQL radius tables with the proper credentials and time.

This script is easy to setup, but the user must have knowledge of Chillispot, provide their own login page, have a PayPal account, and have FreeRADIUS setup to read from MySQL.

The current version contains functions for 1D, 2D, and 3D images, which may be greyscale, color, or multispectral.
Enhancements:
- A limitation in SaveData and LoadData that restricted the size of data has been fixed.
- There are assorted other minor bugfixes.
