Hi, this thread will be a repository for the correction filters for various models of headphones that I created for Viper4Android
http://forum.xda-developers.com/show....php?t=2191223

These correction filters are compiled from interpreting measurement graphs of headphones at various review sites and adjust the audio quality of the headphones towards a reference-grade sound.

These are correction filters not simulation filters<--click for more info

10+ DDC profiles available. Other headphone correction filters available in convolver (.irs) format, with same quality as DDC profiles. 97 headphone models available in total.

2. In V4A's configuration menu, select the vdc file at the end of the list of listening devices for ViPER-DDC to use one of these DDC configs.

Instructions for profiles in convolver (.irs) format
