This is why limiters are such a crucial tool in loudness. Matthew has mixed for a host of star musicians including Akon, SisQo, Ozuna, Sonny Digital, Uri Caine, Dizzee Rascal, Arrested Development and 9th Wonder. Distortion adds harmonic energy to a sound. For decades, musicians and engineers alike have been drawn to the warmth, low-end punch, cohesion, drive, and overall presence of various types of harmonic distortion effects. Playback loudness is an ever-persistent issue in the world of mixing and mastering. We can put a compressor on the guitar buss and set the sidechain input to be fed by the output of the snare. Not only can you measure loudness in decibels, but you can also measure it in perceived loudness. A digital file has a hard ceiling called 0 dbFS, and any signal that exceeds this level turns into harmonic distortion, not playback amplitude.

We don’t really want to make sacrifices to how the end listener will experience the record in order to make the playback level louder … and if for whatever reason we need to, we want to do so sparingly. This is true in the overall mix as well. It won’t. Of course, this can come with serious drawbacks. Let’s say we have a snare and some electric guitars. This will not affect your course history, your reports, or your certificates of completion for this course. Please try again. The loudness standard designed to measure perceived loudness is LKFS (loudness, K-weighted, relative to full scale). It means that if we emphasize our 1 to 4 kHz range, we can get an overall louder playback level. Use up and down keys to navigate. Loudness is our perception of sonic energy. In the world where we have an amplitude ceiling, this is not the case. Of course, there’s a point in which distortion just becomes noise and gets in the way of the song. Awesome. Type in the entry box, then click Enter to save your note. This is particularly true once we add drums to the equation, which I will explain a little more about later. I'd like to receive the free email course. If we’re going for loudness we want to have a minimalistic approach to our, Not all frequencies are created equal. Learn the science behind some of the most essential digital audio terms that pop up in the post-production process. Because this movement happens quickly and subtly, we don’t really hear it as the guitars being turned down. And since commercial records sound so loud — well … everyone wants their music loud as can be. Loudness isn’t just about how we perceive the amplitude of a sound, it’s also about how long we perceive that level. This is done using the Sidechain input of a compressor. Sometimes we want that extra stuff because there’s vibe or emotion there. It’s about dynamics as well. A 3kHz sine wave will sound much louder than a 80Hz sine wave when played at the same volume. Applying harmoni… However, “loudness” is not the same as amplitude. As creators, mixing, and mastering engineers, we really have very little control over how casual listeners will perceive the loudness of the music we work on.

The other big aspect of how the Fletcher-Munson curve may influence our mix is how we handle the bass. Therefore when we’re mixing with the intention of the final playback level being very loud, we can customize the way the sounds are heard and cater to that idea. Join audio post-production engineer Cheryl Ottenritter as she dives into an array of key concepts, explaining how each one plays into the creation of high-quality audio. Because each instrument takes up some of the total amplitude we can actually have, the more instruments we add the less loud they can actually be. The drawback is while the drums can appear basically as loud, they will lose impact because those highest peaks have been cut short.
