Dynamic Mics

Image
A bit of information about Dynamic mics; All dynamic mics have a limited Bandwidth/Frequency Range. The Frequency Response in dynamic mics is known as the contour. It is used to makeup any deficiency in the frequency range. This basically means that it will boost or try to boost any of the lower signals within that frequency Range.This varies on the range of the dynamic mic in question as they all have slightly different frequency ranges. The Polar Pattern is the direction in which the mic picks up the signal. All Dynamic mics are Cardioid or "heart-shaped" in their polar pattern. They are good at picking up signals at the front of the mic but have a bad rear rejection which means they can't pick up signals from the back of the mic that well and they can pick up a bit of signal from the sides of the mic as they have a slight rear rejection. They are suitable for close miking as they can pick up close signals really well due to their polar pattern. The further aw...

Types of Synthesizers and Oscillators

There are 4 commonly used synthesizer waveforms within oscillators; Sine waves, Triangle waves, Sawtooth waves and Square waves also known as Pulse waves. There is a 5th waveform which is known as Noise waves but it is not used as much as the other 4. Sine waves are the pure tone of a single frequency and is also known as the fundamental waveform. The other waves have added harmonics and overtones differentiating them from the fundamental waveform which has no harmonics. Sawtooth waves have harmonics every integer above the fundamental waveform and every right harmonic decreases in half in volume/amplitude which makes the second part of the sawtooth wave shape. Both Triangle and Pulse waves have the same harmonics but they decrease in amplitude differently.  In a Square/Pulse wave the harmonics are a third as low in amplitude but the Triangle waves are a tenth as low. For example if both of these were waves at 100Hz their harmonics would increase to 300Hz, 500Hz etc. Going up b...

What A Compressor Is And What It Does

What is a Compressor ? A compressor can either be a software or hard What Is Compression ? Compression is the procedure of shortening the dynamic range between the louder and quieter parts of a sound or signal. This is by increasing the quieter sounds/signals and decreasing the louder sounds/signals.
