The quality of digital sound reproduction.<\/strong><\/p>\n

Audio coding. Before converting music to another format, you must “unzip” it to WAV.<\/p>\n

\"SOUND<\/p>\n

Sound information. Sound is a wave that travels through air, water, or other medium with a continuously changing intensity and frequency.<\/p>\n

A person perceives sound waves (air vibrations) with the help of hearing in the form of sound of varying volume and pitch. The greater the intensity of the sound wave, the louder the sound, the higher the frequency of the wave, the higher the pitch of the sound (Fig. 1.1).<\/p>\n

Dependence of the volume and pitch of the sound on the intensity and frequency of the sound wave.<\/p>\n

The human ear perceives sound at a frequency of 20 vibrations per second (low sound) to 20,000 vibrations per second (high sound).<\/p>\n

A person can perceive sound in a wide range of intensities, in which the maximum intensity is 1014 times greater than the minimum (one hundred thousand billion times). To measure the volume of sound, a special unit “decibel” (dbl) is used (Table 5.1). Decreasing or increasing the sound volume by 10 dB corresponds to a decrease or increase in sound intensity by 10 times.<\/p>\n

The sound volume the volume of the

Provisional discretization sound. In order for a computer to process sound, a continuous audio signal must be converted to a discrete digital form using time sampling. A continuous sound wave is divided into separate small time sections, for each section a certain value of sound intensity is set.<\/p>\n

Therefore, the continuous dependence of the loudness of the sound at time A (t) is replaced by a discrete sequence of loudness levels. On the graph, this appears to replace a smooth curve with a sequence of “steps” (Fig. 1.2).<\/p>\n

Sync Audio Sampling<\/p>\n

Sampling frequency. A microphone connected to the sound card is used to record analog sound and convert it to digital format. The quality of the digital sound obtained depends on the number of measurements of the sound volume level per unit of time, that is, the sampling frequency. The more measurements that are made in 1 second (the higher the sampling frequency), the more accurately the “ladder” of the digital audio signal repeats the curve of the dialogue signal.<\/p>\n

The audio sample rate is the number of sound volume measurements in one second.<\/p>\n

The audio sample rate can vary between 8000 and 48000 sound volume measurements per second.<\/p>\n

Audio encoding depth. Each “step” is assigned a specific value for the sound volume level. Loudness levels of sound can be viewed as a set of possible states N, for which a certain amount of information I is required, which is called audio coding depth.<\/p>\n

Audio encoding depth is the amount of information required to encode the discrete volume levels of digital audio.<\/p>\n

If the encoding depth is known, then the number of digital audio loudness levels can be calculated using the formula N = 2I. Let the audio encoding depth be 16 bit, then the number of sound volume levels is:<\/p>\n

N = 2I = 216 = 65536.<\/p>\n

During the encoding process, each sound volume level is assigned its own 16-bit binary code, the lowest sound level will correspond to the code 0000000000000000 and the highest – 1111111111111111.<\/p>\n","protected":false},"excerpt":{"rendered":"
