  1. Thank you for uploading these videos! I can’t believe that I can learn something like that on the internet for free!

  2. Awesome. I’m a huge fan of your videos. Thank you for your great videos!

  3. Great videos! Could you maybe cover some more of the synthesis part? Sound design and such? Really like your videos!

  4. Hello. Just a question. When I convert 24bit lossless files to 16bit lossless files (to listen in the car for example) is good to enable "Dither"? Or should i let it set to "Never"? From what i’ve learned from this video i think it’s ok to let "Dither" enabled. I am right ? I know that "car environment" is very noisy anyway (but theoretically).
    Thanks in advice!!!

  5. Yes, you’re right – it’s considered best practice to leave dither on.

    That way, there’s no chance of any quantization distortion on the fade-outs and other quiet parts – most people agree that quantization distortion sounds a heckuva lot uglier than dither noise.

    As far as my own work, the only time I ever turn dither off is when using certain test signals where I know I want total digital black (all 0 samples) during silent parts.

  6. So rips from vinyls to 24bit lossless files are useless because vinyls have aproximately 50dB dynamic range?
    And last question. When recording in 24bit mode (let’s say we have expensive recording tools) we don’t have to add an -143dB noise because electrical circuitry of our analog tools have a maximum dynamic range of -100to-112 dB so they add noise anyway. Enginers uses Diether (when exporting to16bit) because today analog circuits have a little bit more dynamic range than -96dB is that true?

  7. Yes. Different equipment will have different numbers, so those will not always be exactly the case, but in most situations, that’s true.

    Lossless rips are still a good idea, since different people have different hearing and some might hear data compression that others don’t, but 24 bits is usually overkill for vinyl. It won’t hurt anything, but in that case the information 24 bits hold that 16 bits don’t will just be noise.
