'au_dio_equal_mod' is a simulink based "Stereo Player" . This Simulink model has got many featues.
One of the new featues is the Vocal remover that cuts the vocal in a song leaving only the background music . The vocals are not completely removed in most cases, but they are low enough that you usually can barely hear them i.e
it can supress the vocals . For certain styles of music you might end up removing more than the vocals.
The "Stereo Player" model can only play .wav files . It requies a .wav file of 44100 Hz /2 ch /16 b (stereo input). The .wav file that
you will be using must be there in your current working directory ..
The simulink model works in the backend , front end being the GUI made by using GUIDE
Apart from these the model has got many sound effects modeled as subsystems . The following effects are there in the model ::
- Equalizer (In order to use the Equalizer press activate equalizer button and then use the sliders to listen to ur kind of frequency range)
-Balance(Left and Right)
-Reverb-Flang (A combination of reverberation and Flanging)
