The sound will be low in levela precautionso adjust the gain control up, but no higher than ≣dB to keep a little headroom. The Dirac Processor can store eight filters, which invites experimentation.Įach time you exit Dirac Live 3 (after saving), you end up back at the Dirac Processor screen, where you see and hear your newest filter in operation. You can then return to "Filter Design" to design customized filters, adjusting the frequency range of the correction, applying different target curves, or adjusting the corrections to what you like. Now be sure to save your project before exiting.Īt this point, you can exit and listen to music with your new correction or with Dirac Live bypassed. Choose one and name it, and it will be exported. In addition to the on-screen and drop-down assistance, Dirac provides an online guide for these operations.įig.4 Target curve with measured and corrected frequency response for L/R speakers.įilter Export: This screen displays the eight slots in your Dirac Processer where you can store correction filters. Using the gain sliders associated with each speaker, the microphone, and a master gain control, adjust the levels so that the test signals for all channels are sufficiently above the ambient noise level to allow accurate measurements but not so high as to overload the program, your speakers, or your ears. The objective here is to set the volume to the appropriate levels for testing. My system has five main speakers and three subs (as shown). If you have a sub, it will appear to the right of those. For stereo, there will only be Left and Right. Volume Calibration: This screen (fig.1) displays icons for all your active speakers across the top. You can also use an analog measurement microphone, but you'll need to supply the necessary hardware, including, for most such microphones, a mike pre with phantom power. The most common and inexpensive is the miniDSP UMIK-1. Any USB measurement mike will do as long as it comes with a correction curve file, preferably for a vertical (90°) orientation. Select Recording Device: Select a microphone and load its correction file. Click on itmost users will have only oneand proceed to the subsequent menu options. The software then verifies your Dirac account (with account information you provided at purchase) and scans the system for your Dirac Processor. Start the Dirac Live program, and it opens with a big Dirac Live 3 logo (yeah, I know).
Select some music and, while it is playing, download and install Dirac Live.
