Sounds that energize the brain
“Some sounds work just as well as a couple of cups of coffee,” says Alfred Tomatis, a distinguished French hearing expert. This means that we can use music as a…

What is maximizer and why
Maximizer (digital peak limiter) is a dynamic processing device that increases the level of the audio signal during mastering. Sometimes other types of devices are called maximizers, for example, psychoacoustic…

Sound Perception and Compression
Traditional lossless compression methods (Huffman, LZW, etc.) are usually poorly applied to compressing audio information (for the same reasons as when compressing visual information). Some lossy compression methods are listed…

Why do you need compression

Of all the processes used in the production of modern music, signal compression is perhaps the most difficult to perceive. This is primarily due to the fact that often the result of processing the sound by the compressor is barely audible – especially for beginners. Another difficulty lies in the number of variable compressor parameters: they are not as few as it might seem, and besides, changing each of them does not always lead to obvious results. The fact that these parameters are interconnected only significantly complicates the situation. And finally, an ordinary sound engineer can simply bewilder the amazing variety of types and models of compressors – he will have to rack his brains about choosing the right device before proceeding with his direct duties. Here is the trivial example for you: suppose you need to compress the record to hell. Which is better to choose? A compressor based on VCA (Voltage Control Amplifier), or based on an optoelectrical element? Transistor or tube (or maybe a hybrid of both)? Analogue or digital? A hardware compressor, or limited to a program that performs its functions? And so on and so forth. With so many options available, it is not surprising that compressors and compression are still a mystery to many users. However, if you decide to achieve some success in recording and Continue reading

Frequencies to Remember
Classically, the sound spectrum is divided into three parts: low, medium and high frequencies. The frequency limits, although not everyone agrees with this, can be defined as follows: low from…
