Hey,

I have a recording app and want to use this as visualizer, but when receiving audio and setting into it, i am not able to find the proper blast form or any thing nicer in that..

    };

Help is really appreciate asap.

Already spent almost two for combo..

Привет,

У меня есть приложение для записи, и я хочу использовать его в качестве визуализатора, но при получении звука и настройке в нем я не могу найти правильную форму звука или что-то более приятное в этом ...
