TrueRTA Audio Spectrum Analyzer Software

TrueRTA is offered in four levels of performance. The four screen shots below show the resolution for the four levels of operation. Once you download TrueRTA and experience the FREE Level 1 sound analyzer you will likely want to upgrade to a higher level with increased resolution. To purchase an upgrade, just click the catalog link at the top right of any page, select the level you want and submit the order. We will email you a Registration Code. After you receive the code, look under the Help menu and locate User Registration. Enter the code in the appropriate level field. Upon successful entry of the code you will have an immediate upgrade to the level you ordered. Menu items will be activated, providing greater power. There is no need to download the file again. You can always upgrade between levels. If you purchase Level 2 for example, you can upgrade to a higher level later for the price difference plus $5.00. The higher levels can always display data at any lower level of resolution.

Besides the RTA resolution there are other differences that distinguish the four levels of TrueRTA. The table below specifies the detailed features for the four levels of performance.
