This sonic tweak comes courtesy of Sonarworks, and it’s an enhancement of the brand’s app called True-Fi.

For an outlay of €79 you can install this app on a Mac OS or Windows device and have a 'virtual soundcard’ to use as software that processes an audio output signal to 24 bit/96kHz.

Choosing the True-Fi app from a drop-down menu and you get access to a way of ensuring your headphone’s sound conforms to what Sonarworks says is a ‘flat studio reference curve’.

The app is said to improve your headphone’s frequency response and by using filters, corrects for any humps or dips to provide an even response.

True-Fi can also be used to personalise your headphone’s sound to compensate for aging hearing by boosting bass and treble frequencies.

Sonarworks has measured a huge number of models from an equally large number of brands and has now expanded the apps compatibility with 27 new headphone profiles.

It now supports 157 models including Bose QuietComfort 35 II and Sony’s WH1000XM2.

Sonarworks says the uptake of the app has been huge. In fact, over 20,000 professional recording studios are reported to be using it.

While it sounds like a good thing, the True-Fi app can’t compensate for badly designed headphones. The model may have a flat frequency response, but the crappy sound is down to a cruddy design or cheap materials.

As the old saying goes, "you can’t make a silk headphone carry pouch from a sow’s bladder".

Plenty of headphones ranging from the bottom feeders and stretching to high-end models with eye-watering price tags have a faultless frequency response but still sound like two alley cats mauling each other in a trash can.

Conversely, other models measure poorly but sound sublime.

Of the brands supported by the True-Fi app, some have a larger presence than others. Brands that feature heavily are Beyerdynamic, Audio-Technica, Shure, Sony and Sennheiser.    

Helmut Bems, CEO and co-founder of Sonarworks says the future is bright for his app, telling StereoNET:

We are proud to support an increasing number of headphones, and at no incremental cost to the consumer. We are also pleased that we now cover the entire Focal professional range, with the addition of the much requested Clear Professional and Listen Professional models.

Sonarworks offers a 10-day free trial, after which time you can purchase the software for €79.00.
