Hi Thierry,

Just wanted to say thanks for this thread. Lots of helpful tips and tricks. I put together a system with the miniDSP USBStreamer that has 8 channels on I2S output together with 4 Curryman DACs. Using JRivers internal convolution engine. For measurement, I use the ASIO loopback that works without stutters. More details here:

after a first look: very impressive! But one question: How (or where) can a time delay be set? I mean time-alignment-difference between LP and HP (position of speakers on x-axis) in example?

Default Hello,

In the convolver file (.txt)

each delay for each channel can be set manually

see the convolver site.
Config file

and some examples
Config examples

in the 2nd and third line,delay is setting in ms for input channel,
and for output channel in the third line.

44100 2 2 0
0 0 (=no delay in ms for the two input)
0 0 (=no delay in ms for the two output)

44.1khz, stereo in and out, no speaker mapping
No delay on any input channel (feature introduced in version 3.1)
No delay on any output channel (feature introduced in version 3.0)

Take the first (and in this case only) channel from Left.wav
Apply Left.wav to the first input channel
... and output the result to first output channel

Thank you very much!

Is there a description about the measurement-import format from any hardware-measurement-equipment? Would it be possible to upload such a demo-file (for coding an interface)?

Is there any basic-experience how to avoid audible preringing (i.e. no sharper filters than ...)? Over-all (room-) corrections only with minimum-phase-filters?
