Developer's Description

Spect&Gen is an audio measurement environment which combines an audio Spectrum Analyzer, four audio Wave Generators (sine, square, triangular and saw-tooth waves), a white or pink Noise Generator and an Osciloscope . The purpose of Spect&Gen is to perform Audio measurements on audio amplifiers and players: distortion, signal to noise ratio, bandwidth... . The display is very precise with a dynamic range of 130 dB (when the hardware allows such a precision). The output of the signal generator can also be recorded in a "WAV" file that can be transferred to a USB key or a CD for testing the quality of a CD or a DVD player.

To get the best of Spect&Gen you should use a dedicated sound board or an external audio box connected to a USB port. For example: the Creative Sound Blaster X-Fi Surround 5.1 Pro or X-FI HD.
