As input data we need 6 to 9 room transfer function measurements (RTF) for each channel. One measurement position should correspond to the sweet spot. The other ones can be spread randomly around the sweet spot in order to spatially cover your usual listening area (typical distance between sweet spot & other measurements = 30 to 100 cm)
You can use our own solution by downloading the following package (inc. instructions) Measurement tool
The other alternative we recommend is REW. Here are some guidelines for performing the measurements when using REW:
We offer 3 different options for crosstalk reduction.
The required input data for each level are:
When using crosstalk reduction it is recommended to lower the span angle between loudspeakers compared to the traditional stereo configuration. This helps keep a stable image despite head movements. If your room configuration allows it you can go down to 20 degrees angle.
Our correction method requires a specific filters topology putting a specific demand on the convolution capacity of the audio player.
Here is a list of players compatible with our technology: Roon, HQplayer, JRiver, Foobar (together with the VSTconvolver plugin) and any other player with VST plug-in format compatibility or using Brutefir convolution engine (like Volumio).
Filters can be implemented in Audirvana using our dedicated plugin.
With the filters we deliver an installation instruction for your audio player.
For audio players having only a classic stereo convolution we can generate "downgraded" versions of the correction (no cross talk for instance) Such filters can also be used with hardware solutions like the ones from miniDSP.
