GT Analyser

High resolution spectrum analyser.

Redirects to PayPal
Inspect every detail of your frequency domain with our free spectrum analyser plug-in, GT Analyser.

Featuring a high resolution, multichannel frequency analyser, precision level meters, and a simple correlation meter, GT Analyser shows you a great overview of the frequency content of your sound.

The analyser can be fully customised through its many parameters allowing it to be fine-tuned for any application.

GT Analyser now allows you to save snapshots which can later be used as a reference which is ideal for frequency matching.

With a clever and unique algorithm, GT Analyser gives far more low-end precision than other leading spectrum analysers and it’s available entirely for free.

GT Analyser is donationware.
