Dither is a low level noise that is added to the program in order to trim a large digital word into a smaller one.…Since the word length for an audio CD must be 16 bits, a program with a longer word length…like the usual 24-bits used in a DAW must eventually be decreased. Just lobbing off the…last 8 bits degrades the audio, so a Dither signal is used to gently accomplish this task.…An undithered master will have the K-trail stop abruptly or have a low-level buzzing…type of distortion at the end of a fade out. All Dither is not created equally.…
There are currently many different algorithms to accomplish this task.…Each DAW manufacture has either their own version, or one supplied by a third-party.…Sometimes noise shaping, which is a way to increase the signal-to-noise ratio of the…signal is used in conjunction with dithering.…The bottom line undithered is that each type can have a different effect on not only the…music, but song to song on the same genre of music.…It's worth it to try whatever selections are available before settling on a choice.…
First, discover how to configure your monitoring setup, optimize your listening environment, and prepare and print alternative mixes that will allow you to make quick fixes during mastering. Bobby then reviews a selection of dedicated mastering tools that give you precise control over select signal parameters, from compressors to de-essers. He'll discuss the differences between mastering for CD, online distribution, and specifically for iTunes, and how to achieve the best results for each medium. The course wraps with lessons on mastering for high-resolution formats like Blu-ray, as well as delivering and archiving the master recording once the project is complete.
