Wavelet is a good non-root alternative to V4A and JamesDSP. Similar in several respects but more limited due to its non-root nature. Doesn't cause excessive drain in my experience.Thanks, yeah was curious about that. Could be a good alternative.
Does Wavelet work the same as Viper4android, or is it more just a non-root app that may cause excessive drain processing the audio?
(slight off-topic, but relevant given intentions of finding an efficient audio processing equaliser compatible with A13)
