Цифровият звук
Излезе от печат книгата “Цифровият звук – митове и решения” от моя милост – Христо Карагьозов. Надявам се тя да е от полза на всички занимаващи се със звук без значение от специализация и ниво на обучение. В нея са засегнати много важни и неизяснени до момента в българската литература проблеми на дигиталното аудио – дитер, джитер, синхронизация между цифровите аудио устройства, файлови формати, stand-alone рекордери, кодиране на звук, цифрови звукови интерфейси и много други незасегнати до … Read entire article »

Lecture1 – Sound, Characteristics of sound
So, the important points: What is necessary to have a sound, respectively, the feeling for such phenomenon? 1. vibrating unit; 2. Environment in which these vibrations spread; 3. Someone perceiving the vibrations. Definition for sound: Sound – it’s the feeling, caused by the vibration of a flexible body in versatile medium. Next, the characteristics of sound: The main characteristics are four. 1.The first characteristic is the frequency of vibrations. This is the number of vibrations per second. It is measured in Herz (Hz). the range between … Read entire article »

Lecture 3 Part 1 – Analog recording
We use electro-acoustic transducers to capture the sound from the field of the recording. Then we use the opposite type of transducers to play the captured sound through the speakers. Thus we transform the acoustic signal into electricity to be able to operate with it. This is important because we can not capture the sound vibrations, so we need a medium. And this medium is the electricity. But the electricity preserves only … Read entire article »
Lecture 3 part 2 – Digital representation of the sound
In the 80’s a significant step in the improvement of the recording and reproducing of sound was made. The digital technology was born. The principle of the digital sound representation can be different, but the most common is the PCM (Pulse Code Modulation). In it the sound wave, which is continuous, is divided to frames, or, in the digital audio world, SAMPLES. This process is called quantisation. The number of samples per second can be different, but usually it … Read entire article »

Lecture 6 – Dynamic processors
The dynamic processors are processors, which are sensitive to the dynamic range. Usually we can say that they don’t care about the frequency range and frequency bands, like the eq (there are exceptions, but we will not talk about them now). All the dynamic processor is detecting and working on, is the dynamic range. The 4 major types of dynamic processing are: Compressor; Limiter; Expander: Gate. The compressor and the limiter are devices, which are reducing the dynamic range. This is how … Read entire article »

Lecture 6 – Reverberation
REVERBERATION When we have a sound emitted in an enclosed space, upon arrival to the listener it comes with many discrete reflections from the surfaces of the room. These multiple reflections cause auditory impression of “prolongation” of the sound until the reverberation process died down. The amount of reverberation generated by the surfaces of the hall is directly proportional to the magnitude and and inversely proportional to the sound absorption, which is carried out from its surface. The acoustic … Read entire article »
