Hey everyone, I’m having a bit of trouble setting up a SPAT Revolution session for an irregular speaker array.
1. I am working with an irregular array of speakers for an installation (see attached, speakers numbered 1-12). The speakers are in a long hallway and are irregularly placed in the x, y, and z planed though always overhead. I would like to have sound move with each walker as they pass through the hallway by automating sound to move at average human walking speed. I am using Speaker 7 as an origin point (0, 0, 0). A. Which is the correct pan law to use? I have tried DBAP and KNN but the diagram of each speaker seems to be pointing in the wrong direction, esp. at the origin. I would like the speakers to point down towards the floor. B. Is it advised to select a single speaker as the origin point? 2. I have taken surround impulse responses from an array of 7 speakers in a surround setup approx 19m from the origin. The microphone array was 7+4 (height) at 1m from the origin. If spatializing in SPAT, would I make the convolved signal 19m from the origin (where the speakers played the sweep) or 1m (where the microphone array was). 3. In either case, would I compute speaker alignment or normalize? 4. Are you aware of any products that can calculate multichannel irregular speaker distances/correction curves from a test signal? Something like sonarworks or genelec SAM but not proprietary and with the ability to calculate actual speaker positions from test signals rather than having to scan the room (which I currently do using matterport) or measure by hand.
