On the Dutch Hauptwerk forum we had a very interesting discussion about time alignment of the front with the rear speakers. Jan Wim regarded as the audio specialist on the Dutch forum convinced us that time alignment improves the sound of a Hauptwerk surround setup. JW himself uses a hardware sollution, the Bheringer Ultracurve pro deq 2496 (x3) to correct for the roomacoustics and time alignment of the front with the rears.
Other possibilities to time align your setup is Dirac room correction software, see the topic Don Vlasny wrote about Dirac.
However if you use Hauptwerk with Reaper you can use the JS delay VST.
In a normal setup the rears are located in the back of the room. If the distance from the rears are further away then the front speakers then your setup is not time alligned. To compensate this you have te delay the fronts to allign with the rears. Just measure the distance from the front to your ears and the rears to your ears and subtract these distances to calculate the correct delay. use a delay of 2,91 ms/meter to compensate.
So i calculated the distance to compensate (2 meter so the delay had to be 5,82 ms) Then i put the JS delay VST in the front track and set the correct delay.
The result was AMAZING. Not only the sound itself was more pristine but also the impression of being in the real space amazed me much.
Time alignment improves the sound a lot!!
You have to perform some measurments and calculation but once installed the improvement will reward.
May be something to integrate in new Hauptwerk versions?
