.Wav sound modifier

[MHutch]

Overview

This VI allows modification of the sound played from a wav file, and outputs the results to speakers.

Description

This VI gives some standard sound modification opions such as bass, treble and midtone. You can also modify the speed of the track playing and the volume on the output. Visualization of the sound can be seen in the form of the wave itself, and 1/3 octave analysis.

Bass, treble and midtone changes are acheived by use of lowpass, bandpass and highpass filters respectively. The speed of the sound is modified by altering the value of dt using the align and resample VI.

There are two versions of this, as the version with the 1/3 octave analysis requires the sound and vibration toolkit.

Included to download is a festive .wav file.
