I have audio stream in my web application. Need animate dataArray from analyser, but in Safari it is back by getByteFrequencyData() zero array. I know it is bug. But is the another way paining from analyser in Safari?

Alright so I dont know much about Web Audio API and I was just ask to fix the Code. Right now I am able to record something and after that play it. It also has reverb on it. BUT my problem is right now that when I convolve ( I thinkt thats the word for it) it while I record the Audio which plays in the Background for the scene starts lagging. If I only start start to record without convolving its fine.
