Once you have the tilt filter set for the flattest response curve in the RTA, return to your reference material to see how it sounds. If the spectrum analyzer shows a greater degree of high frequencies, set the tilt filter to dark (D) and check the results. If you notice excessive levels in the low frequencies, try setting the Sound Balance filter to Bright (B) and check the results. In the RTA display, the reading should be as level and even as possible. Pink noise is a balanced level of noise across the entire spectrum. Change the Sound Balance filter to see how the response changes the response curve in the RTA. Play the pink noise through one speaker at a time at a reasonable level (~80-85dBA) and place the iPhone or iPad at the listening position.
If you wish to play pink noise from your computer workstation, a WAV file containing pink noise is available at the bottom of this page. Play the pink noise from the Dynaudio Meter and adjust the level for a reasonable playback volume. You can connect the device directly to the speakers using a conventional headphone to RCA adapter. In the Apple App Store, search for “Dynaudio Meter” to locate and download this free app.
We have created an iOS app with these tools built in so you can quickly test and calibrate your LYD speakers using your iPhone, iPad or iPod touch.
