Well, it’s simple.

We make noise.

FiDef employs a highly specialized, patented process to create a custom noise profile that is tightly correlated to the source audio. The noise layer is sub-audible, but FiDef makes use of a phenomena that exploits the brain’s ability to make use of sub-audible noise to enhance the interpretation of sound.

The noise layer also survives the encoding process to lossy formats, ensuring mixes uploaded to popular streaming services retain the sonic characteristics of the full resolution source.

How does FiDef Work?

FiDef employs a highly specialized, patented process to create a custom noise profile that is tightly correlated to the source audio. The noise layer is sub-audible, but FiDef makes use of a phenomena that exploits the brain’s ability to make use of sub-audible noise to enhance the interpretation of sound.

What workstations are supported?

The plugin supports Win/Mac VST workstations and AAX for Pro Tools 10.3.5 or higher using Pace iLok.

Once I turn it on in my session, what should I expect?

The first thing most engineers hear is a decongestion of the overall mix. Each element in your mix will seem to sit better alongside other elements, brining the entire mix into a more musical, balanced focus. Here are common experiences from engineers using FiDef.

FiDef Enhancements

Are there parameters I can control in the plugin?

The plugin is provided with several profiles to choose from, but the parameters we use to build those profiles are extremely complex, using over 300 individual decision steps to analyze and create the perfect complimentary noise signal.

How is FiDef different from dither?

Dither is a process that recovers some of the resolution that is lost when you convert from one bit depth to another. FiDef does not work on the audio data but rather is something that rides along with the audio to signal/activate the brain.

How does our brain detect sub-audible signals?

We’ve all heard of subliminal advertising. A picture of popcorn or a message that says “eat popcorn” is put into one frame of a movie film. Nobody in the audience can see the message that appears for only 1/24th of a second on the screen, but their brains pick up on it easily. Popcorn sales suddenly increase at the concession stand. Sub-audible signals work in a similar way. The listener cannot consciously hear the sub-audible signal, but the brain picks up on it clearly.

Can the plugin support multichannel audio?

Yes, the FiDef plugin sits happily on any bus configuration that your DAW supports, such as 5.1, 7.1. etc. If you find a channel config that we don’t support, please contact us at techsupport@fidef.com.

Will my AAC/MP3’s files sound better if I FiDef them first?

Yes, because the noise layer survives the encoding process to lossy formats, ensuring mixes uploaded to popular streaming services retain the sonic characteristics of the full resolution source.

If FiDef a format?

No. We are a processing algorithm that works with all files at any resolution.
