Removing Noise with AI - RM Noise

Hi Randy, You're right, looking more carefully at the full range from 100 Hz to 2500 Hz the rolloff is more than what I measured between just 500-2500 Hz. Fair point. The deterministic high-frequency boost approach sounds very promising. Option (b) — boosting the neural network's output above ~1.5 k...

Hi Randy, I compared the pure speech spectrum (from your example) with my received SSB audio (RMNoise OFF): Pure speech: 500 Hz = -47 dB, 2500 Hz = -73 dB → rolloff = ~26 dB Received SSB: 500 Hz = -65 dB, 2500 Hz = -67 dB → rolloff = ~2 dB The received SSB spectrum is essentially flat across 300-280...

Hi all, I've done some controlled spectral analysis of the RMNoise "Phone web client version 824e959" model. I wanted to quantify a subjective impression that the denoised audio sounds "dull" compared to the original — and the data confirms it. The same behavior is observed both ...

Yes, that is pretty messy in Windows. It can be space or comma-delimited, depending on the tool/process used to write the DNS entries in the registry. The comma-separated form is most common when the value was written via the Control Panel, PowerShell, or netsh. The space-delimited format is often s...

I just did a quick test on Windows nslookup -type=TXT servers.rmnoise.com 8.8.8.8 Server: dns.google Address: 8.8.8.8 Non-authoritative answer: servers.rmnoise.com text = "rmnoise1.rmnoise.com:11109,rmnoise2.rmnoise.com:11109,rmnoise3.rmnoise.com:11109,rmnoise4.rmnoise.com:11109" I see tha...

Microsoft's documentation says the entries should be "space delimited", but sometimes I am seeing that they are comma delimited

Randy can you clarify? Where do you see comma delimiters, and why sometimes?

It would be nice if the filter settings were retained between restarts of the RMN client.

Short Demo RM Noise web-client on Ubuntu

I have also tested it on Ubuntu with Chromium and Firefox, all working ok. I am piping the Audio from a web-based SDR to RMN web client (in another browser tab) with the help of PulseAudio.

Works great on Windows 10, tested with Chrome, Edge, and Firefox. Trying Linux now.
