hi to set effects you give id of 0 when your create a mediaplayer it gets an id such as 1141 and you can

mediaPlayer.attachAuxEffect(reverb.getId());                reverb.setPreset(PresetReverb.PRESET_SMALLROOM);
but i need to set it to system sound ie. 0 not a mediaplayer is there a way to do this?

kind regards

thanks for reply i tried that but couldint work it out

https://coderanch.com/t/781456/mobile/play-byte-array-mediaplayer

seems you have to write it to a file not sure how that would work as im trying to effect audio on device as it plays

Hi i am trying to build an equilizer for my samsung i have the equilizer done but how do you capture audio from the system for nwerer sdk there is audio capture class but it was only intrduced since android 10 so how could it be done for older phones there doeint seem to be a way to use AudioRecord and feed it into mediaplyer but there must be a way as there are many equilzers on play store that work. any help would be great thanks.

i am trying to capture audio into array and play it through mediaplayer with audio effects but am having problems setting the mediaplayer source and was wondering if it could be done
