Converting while the computer is loaded causes distortions #3

Hi, Thanks for the encoder, it looks great!

When I'm trying to convert to MP3 and my computer is loaded - CPU and memory is above 90% - the output result is distorted. The sound repeat itself for a second or so and then proceeds normally. (Please find an example in the following link: https://db.tt/4RQDxfqr - navigate to second 19)

I'm working with the worker and I'm staring to convert when the recording ends. It reproduces on Chrome and Firefox

My guess is that it's related to the high CPU. I'm hoping to be able to detect the corrupted frames and encode them again. As for now I couldn't see how to do it, any suggestions?

Thanks in advance.

Hi, echoing all above points. The encoder is super easy to use, but I have the exact same problem.

Quick follow up: my distortions (skipping, repeated sounds), were actually caused by issues with the webAudio API, not this codec. Sorry for the false alarm!
