A Limiter is a compressor with a very high compression ratio and a very fast attack time,…so it's able to catch the fast peaks of an audio signal.…In order to understand how a Limiter works in mastering, we have to understand the composition…of a typical music program first.…In general, the highest peak of the source program, a song in this case, determines the maximum…level that can be achieved in a digital signal.…Because many of these upper peaks are very short duration, they can usually be reduced…in level by several dB with minimal audible side effects.…
By controlling these peaks the entire level of the program can be raised several dB resulting…in a higher average signal level, that's what we use a Limiter for.…Most digital Limiters used in mastering or brick wall limiters, this means that no matter…what happens the signal will not exceed a certain predetermined level, and there'll be no digital overs.…A brick wall limiter is usually set anywhere from -1 dB to as high as -0.1 dB, and once…set the level will never go beyond.…
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.
