Hello to everyone,
I have a problem with perfect declipper with breakway asio. When i increase the sample rate to 4096 in perfect declipper i have a lot of cracle in my sound even if increase the buffer size in breakway to 1024. My pc is a intel dual core 3.2ghz 1155 socket and gigabyte b75m-d3h motherboard and 4g ram with hhd adata disk. Any help?

Best.

Do you use it as DSP?
Is it first in chain?
Did you put 1dB attenuator before it or even better 3?

Yes, i use it as dsp in first position. No i haven't use attenator at all (i will try it). Let me say that my soundcard is mariantrace alpha with old driver (2.02) on win7 32bit.

Best.

One more thing. My processor running at 30% of power, is that ok? If i disable declipper with natural Dynamics soun ok (no cracle), or oposite, disable natural Dynamics and enable declipper. Also if i disable clip output and the natural Dynamics and declipper is on the sound goes better but still have some cracle. Some cracles appear if the buffer is on 1280!

Best

The declipper and Natural Dynamics start calculating when there's enough data available - at latency 4096 that's every time it has received 2048 samples. This calculation takes some time (almost none on modern CPU's, but it can be a lot on older ones). If this time is too long it might block Breakaway which could cause this type of effects.

Possible solutions:
- Increase the latency in Breakaway
- Choose a lower latency in the declipper (standard is 4096, but you could try 2048).
- Get a faster pc...

I don't know how the latency in Breakaway works, you might want to ask that one on the Breakaway forum.

Hello,
...so i change the processor to i5 3470. The computer power runs at 12%, but still have the crarcles below 1024 asio buffer. It can run and sound good 4096 declipper latency only at 1280 asio buffer in breakaway asio control panel through phase linear and not low latency. Thanks.

Best.

Weird. But all I can tell you is to ask how the buffers in Breakaway are built up. 1024 (and a lot less too) should really be more than enough if the CPU load is low.
