Using alsa mixer (root) to boost sound in an intelligent way

Question

I'm looking for a way to boost the headphone output of my Moto X (2013). I have rooted it and installed Alsa Mixer so I should be able to run shell scripts and modify it.



The thing is.. I can't find any good guides for this.



What I'm trying to do:
- Boost the volume using a compressor (like radio stations tend to do)
- Maybe apply a limiter after that just to be sure I don't blow up my headphones.



Can somebody help me plz?

Answer

My suggestion is to install Viper4Android. You can increase output by (as I recall) 8dB, and besides that, you will get a lot of options to adapt the sound to get the best output. Using it for a couple of years and still haven't found a better alternative.
