Har-Bal™ is a New and Novel way to an existing puzzle.
What is the noisy Compensation Technology?
When you fulfill EQ on a typical equalizer or mixing desk you can't make a level judgment about whether an individual EQ setting is a very good or not because it is a commonly not noisy compensated. By that we mean for an A/B test of with and without EQ to be unbiased, the observe noisy of the each case must be the equal! If you boost to the midrange on your EQ you will have boosted the overall noise so any in/out test will be biased via your boosted case easily because it is noisy. The only way you can do this on a blend desk is to cut the output level on the EQ’d case but by how many will you cut it?
Dislike blend and EQ’ing on a comfort, Har-Bal is loudness compensated to maintain the equal perceived noisy between filter in and filter out. What you hear in an A/B identification with Har-Bal is truly due to EQ only and not a bias preface by the fact that the perceived Noisy is higher in one.
Without compensating for noisy it is very simple to make EQ mistakes. With the entrance, Har-Bal takes it is very less likely.
What is a Harmonic Balancing?
It is lovely well documented that extended session of listening to improperly mastered recordings as usually leads to hearing weakness that finally takes the desire out of the listening experience. Harmonic Balancing provides a reliable means of correcting and dismiss the tonal imbalances inherent in any song, thus build a more generally pleasing and agreeable sound to the hearing ears. Users of the software detail that this new process has demonstrated itself time after time in producing a harmonically balanced sound from one of that was wanting. When a song is harmonically balanced they declare that the effect can be phenomenal. The goal of Har-Bal is to improve existing frequencies that are in conflict with the natural sound spectrum.
So why is Har-Bal safe than conventional approaches?
To clarify this question let’s reflect upon and clarify conventional approaches. The current habit for mastering of popular music will typically involve a combination of processes including mix-down, dynamic range compression, equalization, and normalization or limiting. Har-Bal principally addresses the issue of equalization in a modern way. After the mix-down, the final blend will more oftentimes than not have some level of active range compression applied to it, either through a conventional compressor or a multi-band compressor like that open in the Finalizer. After compression some degree of equalization may be needed to recompense for the shift in the spectral balance that compression often make, or worse still, to compensate for a poor mix-down. Either way, this is achieved by a studio engineer of depart skill adjusting the controls on a graphic, or more usually a parametric, equalizer while observe the resultant sound through speakers to obtain the desired effect.
“You Won’t accept Your Ears”
The entire process of mastering is gradually reliant upon the experience of the engineer. In particular, the degree to which he or she can decide the music and its deficiencies, or in other words, how well he or she can analyze the recording done listening. Even for the most proficient of operators, this task can be particularly difficult to do well and this, in turn, is a result of the way in which we perceive sound. broker such as masking, poor monitoring acoustics, and poor speakers play a significant part but most importantly the issue of human noisy perception makes the task very hard to do well. Of course this wouldn’t be an issue if we all had extensive funds. An FIR Digital EQ Designed Expressly for Mastering, with a Musician-Friend Interface.
At low volumes we discover it hard to hear low and high wavelength but as the volume increases the spectrum extremes become progressively easier to hear as is illuminate in the equal loudness shape for human hearing display in Figure 1. So enough so that you might discover that if you were to simply turn up the volume you may find that your blend sounds significantly better. So when you combine the effect of noisy sensitivity and equalization changes, how do you tell how much of the change was due to the equalization and how enough was due to the overall increase in observe loudness? For example, you force raise the mid-range by 6dB since it sounds better but do you know if this improvement is really due to the equalization or just merely the in fact that the effective loudness has increased by something less than 6dB? To accurately judge a process that involves changes in frightful balance requires that you account for the change in effective loudness. In the above example, to carefully judge the effect of the EQ change would order that you reduce the overall volume while boosting the mid-range but by how many?

So how does Har-Bal balancing handle this puzzle?
Har-Bal is actually composed of two parts: a spectrum analysis engine and a high-resolution narrow phase digital filter. We handle the puzzle by first analyzing the entire recording. This gives us a measure of the average and peak spectrum comfortable (displayed graphically) from which we can quickly and easily judge the spectral scales of a given recording. Then through a novel user interface, our software allows you to design a matching digital filter that produces the spectral scales that you need and without question. The create filter can be tested by listening to the effect it has on the recording and comparing it with the unbalanced version in real time.
How is this different from the conventional approach?
Firstly, you do not need golden ears to judge where the puzzle areas of a particular recording lie as the spectrum measurement gives you an perfect indication of this. If you find this hard to believe try this for a challenge. Find what you lieve to be your best sounding CD and your worst sounding CD and analyze each in turn. You will find the differences obvious. Figure 2 is an illustrative case in point of two recordings in the same genre but with hugely differing listenability. Can you see why? With experience, you will come to a better understanding of the relationship between a particular spectral shape and the overall sound quality.

Secondly, a typical equalization clean, like those found in other systems, will have only a limited degree of plasticity (i.e. limited boost & cut, Q etc.) and are dislikely to be linear phase filters. Har-Bal, on the other hand, uses an 8192 point extended phase FIR filter whose characteristics are designed to match and compensate for the average spectrum as nearly as possible and the degree to which you can boost and cut a singular region is essentially unlimited.
