Hi all,

https://sourceforge.net/p/equalizera...Documentation/


I am currently using this open source app. I needed a means to get an EQ to sit in between Windows audio and my cisco softphone which I use on a daily basis
to speak with customers. Particularly calling customers who answer on cell phones / especially those from overseas. I can adjust the EQ on the fly.

Once installed you can selectively switch the audio device to integrate with, i. e, Bluetooth headset, Bluetooth headphones, Speakers/Headphones etc.
