The standard ISO for a 31 band Eq is as follows HZ:20/25/31.5/40/50/63/80/100/125/160/200/250/315/400/500/630/800/1K/1.25K/1.6K/ 2K/ 2.5K/3.15K/4K/5K/6.3K/8K/10K/12.5K/16K/20K. But I think that this wasn’t the question, the question was how to calculate it, right? First, every octave doubles or divides per two a chosen frequency. Let’s take as a ...

Here, is there any common low-end level that every song should has? No or Does it just set by ear? Yes. In fact, it should be set by ear, not by eyes. Don't bother with what the spectrum analyzer tells you, it is dumb and doesn't know or say very much. You have to listen for the right sounds. or Does it depend on the music genres? Definitely. Hip-...

Multiband Compression is not something Standard.Most of the time it's a complex procedure but you have to keep in mind that you are doing this to a whole mix which means your dB reduction should be very careful or you might kill it. That's a general guideline though , there are techniques that use aggressive/heavy compression. I would recommend reading the ...

When splitting signals into bands most of the coloring comes from the phase changes that filters induce. If you want to be 100% transparent, you need 0% change in the phase, for starters. To achieve this you can use linear phase EQs/Filters to split the signal in bands, as they can filter without affecting the phase (and as far as I know, those are the only ...

for 1/3 octave steps, multiply the previous band by 2^(1/3) (that's 2 to the power of 1/3 = 1.259921049895). Starting with 20Hz, you'll get 20,25.198,31.748,40,50.397,etc, up to 20480. The 'standard' frequency bands for a 1/3 octave (20,25,31.5,40,50,63,etc) are essentially just for labelling - any practical application would use the calculated ...

Hi Guys I just Found this tutorial where it shows how you can split a signal in 3,4,5 or 6 bands with no loss of quality at all, and i am amazed about this. So i decided to post this video here , so to let everyone know about this technique! It is way more transparent than waves c6 or anything else. In fact is the perfect splitter! He shows how you can ...

You can use some FFT eq's on send tracks, isolating different bands. This will split your bands very accurately. It's is the most accurate (transparent, if you like), as if you mix them back together it will sound exactly the same. That's not to say it will be the nicest sounding option. Imperfections are interesting in themselves sometimes.

For a 31-band equalizer, the formula for the nth band appears to be 10^((n+12)/10) Hz. If you take these numbers, and round the 3rd digit from the left to 0 or 5, the first few frequencies you get are: 1 - 20 Hz 2 - 25 Hz 3 - 31.5 Hz 4 - 40 Hz 5 - 50 Hz 6 - 63 Hz 7 - 79.5 Hz 8 - 100 Hz 9 - 125 Hz 10 - 160 Hz 11 - 200 Hz 12 - 250 Hz These frequencies ...

This is some code that I wrote for GNU Octave that calculates the lower cutoff, center frequency, and upper cutoff. From what I understand it should be close or identical to code that would run in MATLAB. Basically a notes perceived pitch is directly proportional to the logarithm of it's frequency. The idea is to pick frequencies so that the difference of ...

I know it's an older question, but this site provides a guaranteed answer for those sorts of questions: http://www.sengpielaudio.com/calculator-octave.htm As its index is rather chaotic, the best I found way to actually find the information you're looking for is to google for the term you want to know more about, and add "sengpiel" to the search terms. So ...
