Questions & Answers

What is the difference between Dirac Live and DLCT 1.x?

New Dirac Live includes an enhanced phase correction algorithm for improved imaging. Additionally, where the previous version of Dirac Live individually measured the phase of each speaker, this new version also analyzes speakers in pairs. The measurement process is improved as well (and consequently the results) with the possibility of up to 17 measurements and two options for sofa setting (focused or wide imaging).

The new software is designed to be easily modified. The first such update is the bass management addon for Dirac Live, to be released in 2019.

Which OS platforms do you currently support?

We support platforms from Windows 10 to 11, MacOS 10.14+, iOS, and Android.

Can I load projects made with previous versions?

Projects created with DLCT 1.x are not compatible with the newest software.

You can load projects created with 2.x and 3.x in the latest software version. However, you will need a Dirac account. If you do not have an account, please click here:

Can I load a target curve made with previous versions?

Yes, Dirac Live supports formats .targetcurve and .txt.

Why does my speaker appear as “Fullrange” when it is set to “Small” on the unit itself?

This information discriminates between subwoofers and regular speakers, and does not correlate to the small/large setting typically used in AVRs to indicate whether a speaker will be bass managed.

Why is there a red lock on the Master volume in the Volume Calibration page?

This is a safety measure to prevent damage to your speakers and hearing! If you are positive you want to push the volume past this point, you can increase the volume by clicking on the lock (red state). This will then become unlocked (green state) and accessible.

Why is it not possible to change the hardware gain for my microphone?

Some microphones have fixed mic gain and rely on adjustments to the master volume and each channel level to get to an acceptable recording level.

Why is there only one channel to calibrate in the mobile application?

For the mobile application we use channel zero to do the calibration (typically front left channel) and will assume that this value is reasonable for the complete system. For more detailed control over the calibration process we recommend the desktop version.

In which order should I measure the positions?

You may measure the positions in any order, though it is recommended to start with the main position.

How many positions do I have to measure?

In the desktop version you are at liberty to choose how many positions to measure in order to proceed to the next step, however more measurements are better and we recommend to go through all the measurement positions before proceeding to Filter design.

In the mobile application all positions (how many depends on selected setting) must be measured before proceeding to Filter design.

Why am I only seeing up to 500Hz in Filter design?

If you have a license for full bandwidth, please use your account to log into the application as you will then be able to use additional features.

Why am I getting ”Failed to register proxy” when trying to connect to my Arcam unit with Dirac Live?

Please check that the communication settings are correct, it should be set to IP.

I would like to report a problem, how do I contact you?
