No Noise 2 is a user interface-less software application that operates in the background suppressing the particular noise
generated by some PCs on their audio output. This noise intensifies when the pointing device or HDD is active. The noise is generated internally
by the computer and routed directly to the audio output(s). Replacing the sound card, hard drive(s), pointing device and all related
cables does not make any difference. The noise is exasperating and very irritating. Some users completely disable the computer
audio in order to continue to work. No Noise is a software application that suppresses that particular noise to negligible levels. The
development of No Noise was undertaken on a PC built with motherboard VIA® KT 133(VT 8368) 663AS/663AS PRO where the noise was observed.
NOTE: No Noise is designed to reduce ONLY the specific noise observed on VIA® KT 133(VT 8368) 663AS/663AS PRO motherboard based computers. For any other noise this application might not be useful. |
| The following diagram shows the "pure noise" produced on the PC speakers output - no audio is playing and No Noise is not running: |

| If a computer experiences this problem, then No Noise might be the easy solution for it. |
| No Noise uses Fourier Transformations, extensively performing enormous numbers of calculations. It runs in the background at the lowest priority level facilitating all unused processor cycles without disrupting the performance of the foreground applications running at higher priority levels (usually about 15 levels above). For this reason when No Noise is in operation the processor is used 100% or thereabout which can be seen from the Task Manager. |
