Soniqware SG-1 spectral noise gate

Recently, I posted a video showing how @LondonShortwave uses the GarageBand plugin, SoniqWare SG-1, for noise reduction. Since GarageBand is an Apple application, I didn’t believe SoniqWare SG-1 would work on a Windows PC, but SWLing Post reader Jeff Benedict (KB7AIL) writes:

“I run Mac OSX and GarageBand so it’s not really a concern of mine but, according to the documentation, SG-1 is compatible with Windows sound processing applications.
Here’s the documentation from SoniqWare:

p. 17

System Requirements
• Microsoft Windows XP/Vista,
• Mac OS X 10.5/10.6,
• 512 MB RAM,
• VST, VST3, or AU compatible host software

An explanation of the VST and a list of applications for Windows which are compatable with VST plug-ins:

Of course, this comes with the caveat that I do not run any version of Windows or any of these sound processing applications so YMMV.

A short explanation of the different formats for sound processing plug-ins:

Many thanks, Jeff, for the tip!

Many thanks to @LondonShortwave, on Twitter, who made a video showing how to use a GarageBand plugin to filter noise out of shortwave audio in real time. He describes this on his YouTube channel:

“I recently discovered a Mac AudioUnit plugin called Soniqware SG-1 that allows real-time noise filtering based on a brief noise sample (sometimes referred to as the “noise profile” or the “noise fingerprint”). This video shows it being applied to shortwave radio signals, which I believe is a first, as I have been unable to find anyone else who has already done it. In a number of cases, it turns laborious DXing into armchair listening.

The antenna used in these experiments is a Wellbrook ALA1530SP-1 and is positioned indoors. More information is contained in the first few seconds of the video.”

Note that GarageBand is an application only available on the Mac OS X platform. Fortunately, it comes free with every new Apple computer purchase. You can find the Soniqware SG-1 spectral noise gate plugin by clicking here.
