Audacity Forum

Just to follow on from my last.....

I have switched machines and 135 works like a dream on the other machine.

Both of my machines only use onboard audio processing and I had been looking to get a sound card for the Samson C03U that I am using to see if that would make a difference. As it is a usb microphone and I could not find a sound card which would let me connect directly to it with the USB interface to test if the motherboard was the source of the interference.

Anyway I decided to test 135 on the other machine and as I said it works like a dream. The difference is the onboard audio processing capability so far as I can make out.

The Realtek AC97 Audio works just fine for what I am doing. The NVidia nForec Audio codec interface doesn't.

So anybody having problems with regular pops and crumples varied by changes in scan and bit rates ought to take a look at hardware profiles early on in the diagnosis process. i think this was mentioned earlier on in this discussion.!!!!

Hope that helps others get quickly to the bottom of some very disheartening interference issues.

PJB - it sounds like your old computer was struggling to keep up. There are lots of things that can affect this:
Not enough RAM
Too many background processes
Other programs hogging resources
Fragmented hard drive
Short of space on hard drive
Ant-virus interfering and slowing down file writes

Many other optimization tips are scattered around the forum.

Glad it works ok with the new computer.
