Product Information
Specifications:
- Brand: Dirac Live
- Manufacturer: Dirac Research AB
- Functionality: Audio calibration software
Product Usage Instructions
Getting Started:
- Launch Dirac Live software and enter your account details.
- Select your Dirac Live-enabled device from the list.
Calibration Guide:
Volume Calibration:
- Position the microphone at ear height and pointing upward at
the main listening position (sweet spot). - Leave Master output at a low volume and Mic gain at +0dB.
- Adjust volume levels of each speaker until playing back at a
normal listening level.
Measurement:
- Ensure clear line of sight between microphone and speakers and
limit background noise. - Press ‘Measure’ with the microphone at ear level in the sweet
spot for the first measurement. - Move the microphone to indicated positions, measure, and repeat
for all points across the listening area.
Filter Design:
- View average frequency response of each speaker before and
after applying Dirac Live. - Modify sound character by adjusting bass and treble
handles. - Export the filter with desired name and save project before
closing application.
Frequently Asked Questions (FAQ):
Q: What should I do if a measurement cannot be completed due to
Clipping or Low Signal-to-Noise Ratio?
A: You can try adjusting the Volume Calibration and/or
decreasing the microphone gain to address these issues before
proceeding to the filter design page.
Q: Where can I find additional help?
A: You can watch the Official calibration guide or visit the
Support page on the Dirac Research AB website at dirac.com.

Quick start guide
Disclaimer: Dirac Research AB is not responsible for improper use or configuration of Dirac Live software, which may result in damage. Exercise caution, especially when adjusting output gains or boost.
Getting started
· Install the latest version of Dirac Live from www.dirac.com/live/downloads/
· Use an omnidirectional calibration microphone with a calibration file such as the miniDSP UMIK-1 that we recommend for Dirac Live.
· Connect the microphone to your computer.
· Ensure the Dirac Live app has microphone access enabled. You can find the settings in the privacy settings in Windows or macOS.
· Make sure that your Dirac Live-enabled device and computer are both connected to the same local network and have internet access.

VOLUME CALIBRATION At the main listening position, usually called the “sweet spot,” position the microphone at ear height and pointing upward.
Leave “Master output” at a low volume and “Mic gain” at +0dB.
Press play beneath each speaker and adjust volume levels until each speaker is visible and playing back at a normal listening level. Speakers do not need to be equalized to the same volume.
SELECT ARRANGEMENT Choose an arrangement from the menu to match the listening area:
· Tightly focused imaging (9 meausurement positions) · Focused imaging (13 meausurement positions) · Wide imaging (19 meausurement positions)

MEASUREMENT
Make sure that you have a clear line of sight between the microphone and speakers. Limit any background noise.
With the microphone at ear level in the sweet spot, press “Measure” to take the first measurement.
Move the microphone to the next indicated position and measure, repeating the process for all measurement points. Use a roughly even distribution of measurement points across the listening area.
The software might alert you that a given measurement could not be completed due to Clipping or Low Signalto-Noise Ratio. Here are two quick fixes:
· Clipping: Adjust the speaker gain downward in Volume Calibration. · Low Signal-to-Noise Ratio: Increase the speaker gain upward in
Volume Calibration and/or decrease mic gain.
Proceed to the filter design page.

FILTER DESIGN
View each speaker’s average frequency response before and after applying Dirac Live.
Modify the desired sound character by dragging the handles for low-end (bass) and high-end (treble). Alternatively, use classic filter design to draw your own target curve.
