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…

Sound effects

Let’s dwell on the consideration of those manipulations with sound that allow you to achieve the appearance of effects such as, for example, echo, reverb, etc. There are various ways of transforming sound (amplitude, frequency, etc.). Based on these transformations, sound effects are realized. Basically, the goal of sound processing is to give the existing sound some new qualities or eliminate undesirable ones. Sound effects refer to those sound transformations that give the sound new forms or completely change the sound information.

The hardware implementation of sound effects is found in digital signal processors (DSPs). Any more or less decent MIDI synthesizer has a built-in effect processor of one or another complexity (the effect processor is one or more DSPs). Complex effect processors “know how” to apply several different effects to the sound signal at once, moreover, separately for each channel, allowing you to adjust the parameters of the effects in real time. However, the cost of such effect processors is extremely high (like the cost of any other high-performance microprocessor), so professional DSPs are installed only on high-quality musical equipment. On more or less cheap sound cards, DSP is often installed with a simplified set of features: applying one or more effects to all Continue reading

Why do I need an arrangement

There are several interpretations of the word “arrangement”. In the Soviet methodology, it meant transferring finished music to another performing staff, for example, from a piano to a four-voice choir, from a vocal duet to a trombone duet with balalaika. When the subject of instrumentation begins at a music school, students begin to get confused – how is the arrangement different from instrumentation. Another interpretation is variation, i.e. approximately the same changes as when composing variations: changes in tempo, rhythm, size, style. At the same time, significant changes are often made to the author’s melody.

The arrangement can go so far that it completely replaces the original music with another one that is not Continue reading

Vocoders: practice and assortment

Vocoder (English voice coder – voice encoder) – a speech synthesis device based on an arbitrary signal with a rich spectrum. Initially, vocoders were developed in order to save the frequency resources of the radio link of a communication system for transmitting voice messages. Savings are achieved due to the fact that instead of the actual speech signal only the values ​​of its certain parameters are transmitted, which on the receiving side control the speech synthesizer. The speech synthesizer is based on three elements: a tone generator for forming vowels, a noise generator for forming consonants, and a system of formant filters to recreate the individual characteristics of the voice. After all the transformations, the human voice becomes like the voice of a robot, which is quite tolerable for communications and interesting for the music industry.

Vocoder as an unusual effect was adopted by electronic musicians and subsequently became a full- Continue reading
