Mastering audio is the final stage in music production, where the final set of mixed songs are turned into a cohesive album through a variety of processes that make the music sound the best it can, wherever it's played. Join author and producer Bobby Owsinski in this course, as he teaches essential mastering concepts and techniques used by experienced audio engineers. Follow along as he works at Oasis Mastering, a real-world mastering facility, and learn how to apply these techniques to your home or studio setup and make your projects sound better than ever.
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.
Sibilance is a short burst of high-frequency energy where the esses are over emphasized. This requires a special type of compressor called a De-esser to suppress it. Here is an example of a song with a fair amount of sibilance that doesn't yet have the De-esser applied. (music playing) In order to use a De-esser, do the following, after you've inserted the De-esser, raise the Threshold Control until the sibilance is decreased, but you can still hear the esses.
If you can't hear them then you've raised the Threshold too far. In this case the Threshold is called the Range Control. (music playing) Span the available frequencies with the frequency control until you find the exact spot where it's offensive, then adjust the Threshold Control until the esses sound more natural. (music playing) Use the LISTEN feature to determine the exact sibilance frequency.
When using the LISTEN feature, remember that the audio you are hearing isn't in the signal path just the slide chain. (music playing) Don't forget to disengage LISTEN when you found the correct frequencies. Here is what it sounds like with the De-esser applied. (music playing)
