Some TEF EZTUNE Features

1. Set Reference Levels. A large SPL display shows the C weighted SPL. A colored background starts out blue, changes to Green as you approach the home theater reference level of 75dB and then turns red if you go above 76dB SPL.
2. Measure Real Time Analysis. A powerful RTA module allows you to choose resolutions from 1 octave to 1/24th of an octave. Select various decay speeds, or use the THX recommended 20 second time averaging for best accuracy with pink noise. Display NC values in octave band mode.
3. Measure Reflections. While some of our competitors make pretty pictures and claim that they have time domain capability, EZTune utilizes TDS to resolve events down to 26 microseconds. Clicking on the Reflections button automatically finds the time of arrival for the direct energy, then shows you which peaks are significant specular reflections. Easy to read graphics show the time of arrival for each reflection along with its path length. An overlay mode makes it easy to see when acoustical treatments have successfully absorbed a reflection.
4. Measure Frequency Response. By pressing the Frequency Response button, the system will automatically identify the location of the microphone in the room, and then calculate the frequency response, phase and comb filters caused by specific reflections.
5. Predict Optimal EQ. By combining powerful aspects of our TEF Precision Equalization software (PEQ) with the automation in EZTune, we have developed the fastest, easiest way to measure a sound system and then to choose optimal settings for equalization. The display shows both the frequency response, and a list of center frequencies for filters, filter Q and the recommended amount of cut or boost at each frequency.
6. McSquared Modal Calculator. Our good friends at McSquared Consulting have provided us with the use of their powerful room mode calculator, which allows the user to quickly visualize the effects of room modes based on the room dimensions.
7. Custom Report Generator. A recent addition to the EZtune package is the ability to create a customized summary report for the home theater owner. This summary allows for the inclusion of a photograph of the system, showing seats, speakers, etc. Important data is included on the report such as a record of the measured SPL levels for each of the speakers, NC data for up to four seat locations and up to six ETC points indicating distance and type of signal measured (Echo, Reflection, Image Shift, etc.). This data is transferred during the course of making your measurements by hitting the Report button on the data window.
