SDR# now with IF Stage Noise Reduction Algorithm

SDR# has recently been updated to include an IF stage digital noise reduction algorithm. Previously digital noise reduction could be done at the audio output stage, but now it can be done to the IF signal as well. Performing digital noise reduction on the IF stage appears to work much better than at the audio stage. Update SDR# by running the install.bat file again.

Here are some comparison audio files tested on a noisy NFM voice signal for listening.

Original Signal

IF Noise Reduction (set to -12 dB)

Audio Noise Reduction (set to -80 dB)

    Strange, but “waterfall display splitter bug” still not yet fixed :(
    I’ve re-compiled the SDR#.exe (build 1186), that fixes situation (just added panSplitContainer.FixedPanel = System.Windows.Forms.FixedPanel.Panel1;) – replace the original exe with this one: http://yadi.sk/d/weTP92ZdKoqSP

    Its working great!!! Awsome, now its possible to dig in voice SSB and more over noise!!!

    Note of advise:

    If you update, you will lose configurations plugins like orbiton and so. You will have to config again , but no big deal :)
