I am trying to build a react-native audio visualisation animation. For this i need some kind of audio amplitude data of the current playing track.

The Javascript Audio API provide a "decodeAudioData" method which seems to do just that : Providing a data stream of the current playing audio amplitudes.

JS audio API seems to be browser only so i can't use it.

Is there something similar using expo-av or react-native ?

    i am not sure it’s related because i am looking for live audio amplitudes and not a pre-calculated waveform of the whole audio file – Manel Jun 18 '19 at 18:42
