This program calculates the Vibration Response Spectrum (VRS) for a base input Power Spectral Density (PSD).The base input PSD must be in terms of acceleration.The VRS uses point-by-point multiplication of the transmissibility function times the base input PSD. It is thus more accurate than Miles...

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]...
