- Acoustic measurement software
- Cables
What's more when you buy the XTZ Room Analyzer from Acoustic Frontiers you get free post purchase email and phone support to help you get started with acoustic measurement, and answer all your ''how do I use it to...' questions.
Choosing between the Standard and Pro versions
Our advice is to choose the Standard version if you want to use XTZ Room Analyzer for:
- Home theater calibration - set levels with the sound pressure level (SPL) meter and dial in distance settings with the unique 'delay alignment' tool. We've put together a detailed process for using XTZ Room Analyzer to setup the audio side of a home theater system.
- Subwoofer integration - with the high resolution 16Hz-300Hz frequency response and real time analyzer (RTA) modes. Read our blog post on how to integrate a subwoofer in a stereo system using XTZ Room Analyzer.
And choose the Pro version if you want to do the above plus:
- Room acoustic analysis - the software has capability to do high resolution 16-300Hz frequency response and low frequency decay spectogram measurements as well as full range 20Hz-20kHz frequency response and 2D/3D waterfalls to analyze reflections and check for flutter echo. You can compare the measurements taken with XTZ Room Analyzer to those in our acoustical measurements white paper.
- Room correction - the software automatically generates correction filters for room modes which you can then further optimize using the unique parametric software emulation mode
A full list of software differences is shown in the 'Features' Tab. The hardware in the Pro version is improved over the Standard with a higher quality microphone (accurate to +/-1dB) and soundcard which make it much more suitable for full range acoustic measurements.

Runs on Windows only
A computer (PC) running Windows XP, Vista or 7 is required to operate the software package. It will also run on a Mac with Bootcamp or Fusion (not on OSX!). One USB port is required to connect up the measurement microphone and external soundcard. The software must be downloaded using the provided serial number found on the packaging from the XTZ support page. The software can be re-downloaded at anytime if needed.
