Breezer 2013 Series - The harmonics analyzer

Hi guys, I'm Michael Shlepp and I'm part of the Breezer development team.

I have the honor to introduce a series of (bi-weekly) posts. A series which has only one goal: explain what you'll find in the next version of Breezer codenamed 'White fox' (seriously, we're using that name internally).

Those posts are also the right place where you can partecipate to the development process by sharing your comments and suggestion! And trust me, we listen, we listen a lot to our user base, so that your feedback will count!

For the grand opening I want to talk about one feature: the harmonics-anlyzer.

The harmonics analyzer: why and for what?

Well the why part of the question is quite easy to explain: because it's useful and when you get used to you cannot come back! How many times you listen to a sample, but you didn't know how it will blend with the others? Sure you have the layered player which helps a lot, but it cannot tell you what are the predominant notes in a sample.

That's the job of the harmonics anlyzer: represent graphically the frequency distribution inside the sample you're playing, and it goes a step forward: it guesses (with an extraordinary precision) the two strongest note in the sample. So you could drop it into your DAW software, and you can be sure, it will mix good.

Obviously is a quite expensive task for the cpu so do not expect that a pc from 2004 will shine, it will be usable but less precise. Also we see that under Windows XP the performaces (not only of the harmonics analyzer) drops by a 25% or even 30% on the same hardware configuration.

Now that we introduced it, let's take a look.

The harmonics analyzer window

Cool eh? As you can see the window is dominated by the spectrum anlyzer which shows the various frequencies that make up the sample. We add an exageration filter which emphasizes only the most dominant frequencies. Also the peaks are a little bit lazy so your eye has the time to follow the frequency shifts (very common with voice and wind instruments).

But we go even deeper and directly in the spectrum view we add two small labels that shown the exact note that falls in the two peaks. Internally it uses a table of known notes and frequencies to speed up the note lookup, and even better, it makes the guess much more precise.

In the command bar (the bottom of the window) you can control the input-sensibility and frequency/intensity scaling algorithm. For your convenience the analyzer can stay above every other window.

How much I have to wait?

To be honest the first condition imposed to me, when I proposed a new post about Breezer 2013 was quite clear "Do not talk about any release date". Why? because we are quite far from even the first beta. In my opinion we will see Breezer 2013 only next year... but it's quite hard to predict.

I hope that you enjoyed that article and I'll wait you for my next article where I will explore the new user interface of Breezer 2013.

Revel Software blog now open!

Come in we're open

Hi guys,

we're proud to announce that (finally) we have a blog! Updated bi-weekly.

We decided to create one because we want to share more information about our products, their development and get even more feedback from you!

So we choose to drop the forum idea (which is much more complex and less intuitive) and go to a more friendly blog format.

Here's also the place where we will post news and updates about our products, and where you can interact with us via Facebook or Twitter.

Best regards,
Suzy Rossi - Revel Software Relations
