    1) I use DVE to do my 6.1 audio calibration and have a question: should I use the band limited pink noise or full bandwidth pink noise for the 75 dB SPL calibration? During the explanation on how to do it, the narrator says "band limited" but the video shows a demonstration with the full bandwidth pink noise. I'm using the band limited pink noise, but I'm still confused whether I'm doing the right thing.

    2) Also, the primer on this forum says to place the SPL meter at a 40 degree angle, but DVE says to point it vertically up towards the ceiling. What's the right way to do it?

    1. Band limited - the reason is that full range may give false results due to the way low frequencies behave in your room.

    2. Depends who you ask. I favor pointing it straight up, but in reality, you will likely get very little difference if you angle forward a bit.
