Crackling in Reaper when SD3 track is armed

[Jerry Scheff- 1-2]

Hello,  I have Windows 10 64    Reaper latest version and SD3.

I have created midi drum tracks in reaper.  When I arm the master  SD3 track very loud crackling starts and I cannot record.  I have been to the Reaper forums but no joy.

Any help would be appreciated.

I also use SD3 and Reaper.  I believe the cracking sound you are experiencing is being caused by a too small buffer and too small  sampling rate in the ASIO configuration for your Focusrite interface.

In Reaper select Options, Preferences, Audio , Device.  Click the ASIO configuration button.  From the ASIO control panel open the Buffer Settings tab.  Increase the ASIO buffer size and  the other option.  For my ASIO device the other option is named “USB Streaming Mode” but with the Focusrite interface I believe it may be called “Sample Rate” or something like that.

That should fix your problem.

Thank you, GV,

I had to fool around with asio config buttons and the request rates but I got rid of the noise. Scarlet device settings: sample rate 44100, Buffer size 1024

Now I have a very bad Latency problem. Request sample rate:  44100.  Request Block size: 160.

 

What do you think?

Buffer sounds high.  I keep mine at about 64 or 128 when I record, to avoid latency.

If the sample rate isn’t the same on all devices, then crackling can occur.

It’s just a big mess GV and Drum Dude. There has to be something else going on.  This noise only happens when I arm SD3. I have other big programs like Omnisphere and it doesn’t happen on them.

Thanks for your help. I will keep trying, get the latency down and use a workaround . Very frustrating. I have had a little crackling in the past but it’s just recently got this bad.

With a relatively inexpensive interface like the Scarlett it not uncommon to have to adjust the sample size and rate to optimize it for recording (low latency) and mastering/rendering (Large sample size).

http://Im having the same issue.. im recording in 48000..i read sd3 samples are 44100? Can this be an issue?
