This project is a software tool for processing digital audio information. The software program provides a graphical user interface (GUI) to waveform manipulation through a visual waveform display window and menu system. Keyboard and mouse input devices allow the user to perform basic editing functions, such as cut, paste, trim, and mix, as well as to perform more advanced algorithms utilizing digital signal processing techniques. A radix-4 fast Fourier transform allows the efficient computation of operations such as finite impulse response filtering, and spectral analysis. Waveforms may be imported from and exported to a computer's file system in the RIFF audio file format (as ".wav" files). In addition, this program allows a workstation equipped with a supported 8- or 16-bit sound system to playback and record digital audio.
