Active and Passive Monitors

Often I get asked the same question about which to get; active monitors or passive monitors with a separate amplifier? To answer this, I need to first explain the differences between the two. It is commonly understood that active monitors simply have a built-in amp and therefore need no external amp to drive them, and […]

Fixed and Floating Points

If you consider the dynamic range of varying bit depths, 1 bit being roughly equivalent to 6dB of dynamic range, then it makes sense that the higher the bit depth the higher the dynamic range. With 24 bit depth the dynamic range (theoretically) is 144dB. Bearing in mind that our hearing does not even come […]

Signal to Noise Ratio – S/N or SNR

This is the level difference between the signal level and noise floor. The best way to describe this is by using an example that always works for me. Imagine you are singing with just a drummer. You are the signal and the drummer is the noise (ha.ha). The louder you sing or the quieter the […]

RIAA Amps and Standards

Most turntables that are stand alone will require a preamp to boost the signal so that you can record an acceptable level. Some turntables, particularly those that are housed in hi-fi units, will have an amp built in, but for the more pro decks, or DJ turntables, a preamp is required. The choice of preamp […]

Sound Waves – What is Sound and how does travel in a given space?

Understanding how sound travels in a given space is critical when setting up speakers in your studio. Sound Waves   Let us have a very brief look at how sound travels, and how we measure it’s effectiveness.   Sound travels at approximately 1130 feet per second (about 1 foot per ms). By the way, this figure is […]

Sampling Tools and Procedures

This month’s tutorial is going to concentrate on the basic and general tools available for the sampling process and will not focus on the more detailed or esoteric tools that are adopted to further hone the sample. So, let’s start right at the input stage of the sampler or sound card. We have already covered […]

Sampling Techniques and Best Practices

I find that the most common hurdles that beginners face is that of understanding how to use their samplers, how to hook all the devices up to each other, and how to then manage the samples. The best way of tackling these sub topics is to give you some pointers and guides, and from there, […]

Sinusodial Creation and Simple Harmonic Motion

The first premise to understand is that simple harmonic motion through time generates sinusoidal motion. The following diagram will display the amplitude of the harmonic motion and for this we need to use the term A in our formula. We will also be using θ. I have used the equation A sin θ where θ completes one cycle (degrees). […]

The Pan Law

So, what is Panning Law and does anyone really care? Hell yeah! In fact, I can state that many producers/engineers that I meet have little or no clue about the panning law. As far as they are concerned, you turn the knob and the sound moves from one side of the stereo field to the […]

Synthesis and Sound Design – Various Types

ADDITIVE Does what it says on the tin. By adding one or more basic and simple waveforms together and their harmonics you create a complex waveform. However, you need to add an enormous amount of harmonics to create the simplest of sounds and this type of synthesis can be complicated to create in the form […]
