Following on from the previous quiz on Percussion Frequencies, we’re opening up a new quiz today: covering Frequency Bands and Harmonics.

Once you’ve got to grips with the starting material in the Frequency Fundamentals course, you should find you’re getting a good sense of where different frequencies lie in your hearing range. The second half of the course then introduces the 10 standard bands of frequencies used when analysing audio and making adjustments to the frequency balance:

Today we’re taking a quick breather in the Frequency Fundamentals series, for an introduction to two important topics for audio engineers: EQ Feathering and Spectrum Analyzers. Once you’re familiar with both of these, you’ll be ready for the final part in the series, on harmonics of sounds.

…Here is the answer to the mystery bonus question at the end of the last article. If you’ll remember, I asked:

What is EQ feathering?

Answer: EQ feathering is a way of applying, or rather spreading equalization through adjacent and tangential frequencies on both sides of the main frequency that you are trying to adjust, thus resulting in a smoother tone curve.

Confusing?

Don’t go away just yet. Let’s look at a working example….it will be a much clearer answer! Click to read the rest…

We now continue our discussion of the 10 audible octaves. We left off at Octave 5 in Part 1. Onward….

Characteristic Sounds: Bands 6-10

Octave 6 (640-1280Hz)

This is midrange land again. Remember Octave 5, and now 6 are referred to as the projection octaves.

Specifically, here in Octave 6 rests the difference between Click to read the rest…
