SLab is a digital audio recording software suite for UNIX platforms. It is currently supported on most versions of Linux, and FreeBSD. SLab is a multitrack harddisk recording application, a set of tools to record music to disk on a PC platform (running Unix of course). The application is software...

CMIX is a computer music "language" designed to create and manipulate soundfiles, or files containing raw binary data which can be converted into sound on a computer equipped with an appropriate digital-to-analog convertor. It is somewhat similar to CSOUND and CMUSIC (two other popular software...

USBDM is a debugger hardware interface for a range of Freescale microcontrollers. It is designed to work with Freescale's Codewarrior software under Windows and Linux. More recently basic support for Coldfire with Codesourcery Tool chain has been added (WIN only). The attached files provide a...

The sound denoising algorithm is based on the popular spectral subtraction technique. Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1-3]...
