  1. im on cmb3 (preinstalled dsp manager), geeky, and forfivo kernel, with modded theme..

    would this mean chaos if i flash this sound mod?

    i mean would there be any interference between dsp and this one?


    1. Well, you need to disable dsp manager first in setting > manage apps.

  2. which 1better between dsp manager and acid audio?

    1. For me, dsp manager is better. Acid is also among the best in providing a better audio.
      You can try both of them and decide for yourself.

  3. Thanks first for describing with this interesting talks with me…Just looking forward for something new.

  4. I like this app a lot, i have it in my phone.Features like GPS devices or portable gaming devices etc are the basic thing behind the success of smart phones but there is fact that Mobile apps are playing a major role to maintain the market value and user's interest in the product.
