AI Noise Reduction

I am sure anyone who suffers with unwanted noise on receive and is a little tech-savvy, will be interested in this. The video was based at ham users, but I see no reason why CB or other users can't try it out, as long as you can get an audio out to your PC via an extension speaker or headphone jack.

The filtered audio in the demo is comparable to my BHI DSP NES10-2 MK4 speaker output. Some might not like the slightly artificial sound at the highest processing level, but if you're chasing weak DX, DSP processing can make the difference between hearing a station or not. So worth a try, no?

The Station Master platform mentioned in the video is not required, but if you want to use that too it is free to join up and open to CB users and Hams.

Interesting stuff there Neal and thanks for posting up.  
(Something I haven't come across before.)

I shall investigate further and maybe have a play later.

I do now have a radio with DSP features and try as I might I still find the old ear & brain seems to work better especially if the signal is buried in the noise. DSP seems great for those signals above the noise but when in the noise tends to become a garbled mess unless I run the minimum of DSP. Will be interesting to see if this software works any better.

Do you know if there is a big latency/delay involved with this?

Either way, worth a play and as you say it could help the CB DX'ers out there whose radios are bereft of such functionality.

In the video Stu says there is a 200ms delay, which isn't bad compared to some web SDRs. Whether the delay will worsen with more traffic, I have no idea.

I downloaded and installed the software yesterday and mailed the creator to obtain login details. I thought it might take a long while to hear back seeing as it was a weekend and the product having some publicity, but he mailed back the same day.

Once I've worked out the correct setting on the radio to get SSB audio into the PC, I'll give this a go and check out the latency myself.

Left it running for a while last night just using the filter as it is, which no recording to learn from by me. The audio was very good, did a great job. I would say just as good as my BHI speaker. A good thing about it is that it has a sliding control, where as the BHI speaker just has 8 pre-sets.

The worst delay I saw was 0.483ms. Averaged between 0.150 and 0.250ms. I've just seen another video HERE by M7BCN which a trial by him. His delay is a lot less than mine was, I guess better internet than me, but audio seemed a bit over processed to me in the vid and I struggled to make out everything that was said even though the noise was very much cleared up. Maybe he'll get better results when he has fed the AI with his noise so it can learn.
