Soundtrack is a wave (WAV) file processing and editing software package. It is available free of charge from our download page. Soundtrack can perform many of the signal processing functions offered by commercial packages. Soundtrack also incorporates the Signal Wizard filter design engine, allowing sophisticated filters to be implemented with just a few key strokes. It is an ideal package to use in a learning environment, since many key DSP operations taught at undergraduate and postgraduate level can be executed using its simple menu structure.

Features:

• Signal additions, subtraction and modulation
• Gain, root, square, half-wave and full-wave rectification
• Signal noise addition
• Signal delay
• Nonlinear scaling
• FIR filters, arbitrary
• True adaptive and single input adaptive filters
• Hilbert transform (quadrature), demodulation and frequency shifting
• Up and down sampling, baseband sampling
• Musical effects: plucked string, echo, reverb, flange, chorus, vibrato and distortion
• Multi-tone sine wave synthesis
• Noise generation and frequency shaping
• FFT lengths from 64 to 32768
• Full audio playback, with pause and stop
• Flexible plot interface for time and frequency data
• For Windows XP, Vista and 7
