Those interested in the Analog sound category often ask the following questions:

☑️ What is analog sound and example of analog sound?

analog audioRefers to recording audio in a format of continuous vibrations that are analogous to the original sound waves. Before audio recording became digital, sounds were "carved" into vinyl records or written to tape as magnetic waveforms. Contrast with digital audio

☑️ How are analog sound waves converted to digital sound?

  • Digital audio. An analog audio system converts physical waveforms of sound into electrical representations of those waveforms by use of a transducer, such as a microphone. The sounds are then stored on an analog medium such as magnetic tape, or transmitted through an analog medium such as a telephone line or radio.

☑️ What makes a sound wave an analog signal?

  • A sound wave is an analog signal. Sound waves are created by vibrations, and sound can be recorded on vinyl records with grooves that cause the needle on a record player to vibrate. Those vibrations are then amplified to play back the sound that was originally recorded. The pitch, or frequency, of that sound can take on a wide range of values.

☑️ How does an analog lp record sound like?

  • Analog - LP Records. The old LP record format is totally analog. The sound signal is recorded as little hills and valleys in the plastic groove that runs around the record. For playback, a needle sits in the groove, the record spins, and the hills and valleys make tiny up and down movements of the needle.

☑️ How are sound signals recorded in an analog format?

  • The signals in the different domains are in 1-1 correspondence -- one goes up, the other goes up. The old LP record format is totally analog. The sound signal is recorded as little hills and valleys in the plastic groove that runs around the record.

Is a square wave an analog or digital wave?

This question has become the point of much heated debate here on WikiAnswers, and I will attempt to pare down the answers to its simplest form while keeping all valid viewpoints intact. Any further debate should be put in the "Discussion" area.The Case For Digital: With a few exceptions, a square wave in it's theoretical form will most likely be used in digital applications.A square wave may be "analog" during the time it is in transition from one stable state to another, and "digital" when it is in one state or the opposite state (i.e., voltage level), according to the type of digital inputs stimulated, but a transition is not an analog state function in the context of computers or digital logic. A square wave has two states hi and low and the transition from hi to low can be switched up to gigahertz (GHz) frequencies. Test equipment manufacturers are able to generate square wave signals well above 100GHz. Function generators have the square wave signal where the transition can be controlled. Practically all digital circuits utilize these states as "1" and "0" (or true and false) that computers use to make decision at the machine language level. Furthermore all modern computer uses this signalling scheme. But digital signals (1's and 0's) are not necessarily "square" waves, strictly speaking. A clock circuit generates a square wave that is used as a timing reference for the address, data, and control circuits.The Case For Analog: All theoretical waveforms look great on paper, but it is impossible to produce any perfect waveform. Therefore, all waveforms (including square waves) are inherently analog.By Fourier Analysis, a square wave is actually an infinite series of the summation of sine waves, in this case the odd harmonics divided by N. As a result, a square wave can actually be considered an analog signal. Looking at this another way, no pulse driver, conductor, or transmission line is perfect, so the rise and fall time of a square wave are not instantaneous, meaning that the series is not really infinite so, again, the square wave is analog, although quite complicated, but still analog. We call it digital because we sense it with discriminators that decide the "value" of the wave based on some thresholds with appropriate hysteresis.The Case For Sanity: A wave form is not inherently digital or analog. "Digital" and "analog" are arbitrary words used to describe an application of waveforms. In other words, all digital signals are square waves, but not all square waves are digital.A square wave is usually used in digital applications, but is also used in audio applications for a "distorted" guitar or vocal effect. A sine wave can become a square wave if the input signal on an amplifier is too great for the power of the circuit to amplify, "clipping" the high and low portions of the sine wave.A square wave can be considered an analog or a digital signal. A perfect square wave (not possible to generate based on Fourier Analysis) would not in general be considered an analog signal because it only has two values, defeating the point of analog (in many cases, but not all). One can make a square wave oscillator to use as an alarm - different frequencies were used to convey different information. A square wave was simple to create, thus my reason for using as opposed to a sine wave (this is an example of an analog use of square waves - the information is not stored in the two values of the wave, but in the "infinite frequency range made available by the extra circuitry to change frequencies."This point is moot, really, because it is the nature of the data (being analog or digital) that truly is important, and defines whether the wave should be catagorized as "analog" or "digital".Oh-So-Clever Analogy: A wrench is the perfect tool for fixing trucks, but if I use the wrench to fix a desk, that doesn't make the desk a truck. In short, the application defines the state, but does not limit the tool.

What makes a sound a sound?

Sound is vibration of (mostly air) molecules. Humans hear sounds from about 20 Hz (=20 vibrations per second, deepest bass) to about 20.000 Hz (20.000 vibrations per sec., very high sizzling) The vibration is tranmitted from the air to your ear and your brain interprets it as a sound. So actually YOU make a sound a sound :-)

How does sound affect the perception of sound?

  • Hearing. Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude, or height, of sound waves. The greater the amplitude, the louder the sound perceived.

  • Sound is detected when a sound wave causes the eardrum to vibrate. Typically, the diameter of the eardrum is about 8.4mm in humans. When someone speaks to you in a normal tone of voice, the sound intensity at your ear is approximately 1 * 10^-6 W/m^2.

What sound wave phase makes the loudest sound?

Why are some sound waves louder than others?

  • Sounds travel as waves of vibrations. The bigger the waves, the more energy they carry, and the louder they sound. When they arrive at your ears, louder sounds push harder against your eardrums. From rustling leaves to jet engines, the human ear can detect an amazing range of loud and quiet sounds.

What is sound and how is sound produced?

Sound is a physical entity, unlike noise which is the perception of sound. Sound is an high pressure wave front through a medium (such as air, or a liquid such as water, or a solid), wherein the wave front is followed by a reciprocal pressure differential behind it. Sound is produced when something disturbs the medium and sets in motion the molecules in the medium. Frequently, (no pun intended) the wave front/reciprocal entity occurs as an oscillating wave, wherein there are a series of wave fronts (peaks in pressure), followed by wave valleys (lower pressure). The relative height of the peak translates to how much energy is in the wave (how great is the pressure), and the closeness of peak to peak (spatially and temporally) indicates the pitch. Noise, is not a physical entity, but is the mental perception of the physiological response to sound. A wave front is converted from mechanical energy in our ear into an electrical impulse in the brain that analyzes the wave information. The interpretation of the wave front is subjective and the brain may interpret the wave signature as speech, music, clapping, gunshot, hum, etc.

How does a sound amplifier improve sound quality?

  • To put it simply, in the case of a sound amplifier, for example, the amplifier takes sound at its input end and produces a louder sound at its output end while aiming to reduce distortions as much as possible.
