Audio encoding.<\/strong><\/p>\n

\"AUDIO<\/p>\n

Digital audio is an analog audio signal represented by discrete numerical values \u200b\u200bof its amplitude.<\/p>\n

\"audio<\/p>\n

Sound digitization is a technology with a divided time step and subsequent recording of the values \u200b\u200bobtained in numerical form.<\/p>\n

Another name for digitizing audio is analog to digital audio conversion.<\/p>\n

Sound digitization involves two processes:<\/p>\n

sample (sample) a signal over time
\namplitude quantification process.
\nMeanwhile, there is no need to worry about it. ”<\/p>\n

Discretization of time.<\/p>\n

Meanwhile, there is no need to worry about it. ”<\/p>\n

The time sampling process is the process of obtaining the values \u200b\u200bof the signal that is being converted, with a certain time step: the sampling step. The number of measurements of the magnitude of the signal, carried out in one second, is called the sampling frequency or the sampling rate, or sampling frequency (from the English “sampling” – “sampling”). The lower the sampling step, the higher the sampling frequency and the more accurate representation of the signal that we will obtain.<\/p>\n

This is confirmed by Kotelnikov’s theorem (in foreign literature it is found as Shannon’s theorem, Shannon). According to him, an analog signal with a limited spectrum can be accurately described by a discrete sequence of values \u200b\u200bof its amplitude, if these values \u200b\u200bare taken with a frequency that is at least twice the highest frequency in the spectrum of the signal. That is, an analog signal in which the highest spectrum frequency is F m can be accurately represented by a sequence of discrete amplitude values \u200b\u200bif F d> 2F m is satisfied for the sampling frequency F d.<\/p>\n

In practice, this means that for the digitized signal to contain information on the full audible frequency range of the original analog signal (0 – 20 kHz), it is necessary that the selected sample rate be at least 40 kHz. The number of amplitude measurements per second is called the sampling rate (if the sampling step is constant).<\/p>\n

The main difficulty of digitization is the inability to record the measured signal values \u200b\u200bwith perfect precision.<\/p>\n

Analog to digital converters (ADC).<\/p>\n

Meanwhile, there is no need to worry about it. ”<\/p>\n

The above process of digitizing sound is done using analog-to-digital converters (ADCs).<\/p>\n

This transformation includes the following operations:<\/p>\n

Bandwidth limiting is done by a low pass filter to suppress spectral components that are more than half the sample rate.
\nDiscretization in time, that is, substitution of a continuous analog signal with a sequence of its values \u200b\u200bat discrete moments in time: samples. This problem is solved by using a special circuit at the input of the ADC – a sample and hold device.
\nLevel quantization is the replacement of the signal’s reference value with the closest value of a set of fixed values: quantization levels.
\nEncoding or digitization, as a result of which the value of each quantized sample is represented as a number corresponding to the ordinal number of the quantization level.
\nThis is done as follows: a continuous analog signal is “cut” into sections with a sample rate, a discrete digital signal is obtained, which goes through a quantization process with a certain bit depth, and is then encoded, that is, it is replaced by a sequence of code symbols. To record sound in a frequency band of 20-20,000 Hz, a sampling frequency of 44.1 and higher is required (today there are ADCs and DACs with a sampling frequency of 192 and even 384 kHz). To obtain a high-quality recording, 16 bits are sufficient, however, to expand the dynamic range and improve the quality of sound recording, 24 (less often 32) bits are used.<\/p>\n

Meanwhile, there is no need to worry about it. ”<\/p>\n

Encoding methods.<\/p>\n

Frequency modulation.<\/p>\n

Sound coding methods (of course we mean the electrical signal coming from the microphone) are based on the fact that, in theory, any complex sound can be broken down into a sequence of the simplest harmonic signals of different frequencies, each one of which is a sinusoid, called the original signal spectrum. The task of encoding sound, like any other analog signal, is to represent it in the form of another analog or digital signal, more convenient for its transmission or storage in each specific case.<\/p>\n","protected":false},"excerpt":{"rendered":"
