  • If it helps for a future purchase, Focusrite’s external interfaces have been amazing for Linux support.

    To the point where I didn’t even notice; It just worked perfectly out of the box.

    I’m assuming you’ve already checked this, but is your interface set to the same frequency/bit depth between Linux and windows? Or if it uses optical, whether it’s set to the same word clock source.



  • Where I live, there is no restriction (other than the standard policed ones) on using amps etc.
    This means on a 500m pedestrianised high-street, every Saturday is 6+ separate people making noise.
    It gets unbearable, because while one in ten is actually half decent, the other nine are cranking the backing track up as loud as possible to get some people paying attention.

    I don’t live in London, but am I correct in thinking that TFL made people do auditions for busking spots on the tube?
    That seemed to be a neat way to improve the quality. And did make me laugh the one time I had to wait just outside a station, then realised that the busker was playing the most well known 30 seconds from Wonderwall over and over.













  • Maybe the best way to think about it is not dark, but the absence of more light.
    On a DMD projector, we use tiny micromirrors for each pixel which flash thousands of times per frame of video.
    The flash/no-flash ratio decides how much light makes it out of the projector. This gives us over a thousand light levels per colour channel, from near dark, to full light.
    When the mirrors are not in position, the light output is very low. (1/1000th of the full output, on a projector with a static 1000:1 contrast ratio)

    The screen is designed to reflect light well, which means in a non-perfect room, it will have a light floor of the reflected ambient light, plus whatever still makes it through the projector (as Cygnus mentioned, room treatment).

    If you do treat a room well enough that the small amount of light that makes it through the projector at all-off is a problem, you can do things like fitting an ND filter to the lens (reducing the full light output, while also reducing the minimum).
    Or you can use the dynamic iris fitted to some projectors (which reduces the amount of light being put out based on the overall scene illumination, similar to the way LCD TVs lower the backlight level to “reach” contrast ratios of 100000:1).
