The first step is amplification of the sound that is picked up by a microphone. This usually consists of a basic 'pre-amp' section which brings the audio signal up to workable levels, and a secondary amplification which makes the signal strong enough to be processed by the recoding circuit.

Are the waves created in step 6 transverse or longitudinal?
The waves created in step 6 are transverse waves. Transverse waves are created when particles in the medium move perpendicular to the direction of energy propagation. In this case, the particles of the medium move up and down while the energy of the wave moves horizontally.
What happens when two waves that are in step meet?
When two waves that are in step meet, they combine together to form a wave with greater amplitude. This is called constructive interference, where the peaks of the two waves align and reinforce each other. The resulting wave will have a higher intensity and energy.
What magnet is used to convert sound into electrical signals?
Microphones are used to convert sound into electrical signals.A microphone has 3 parts to it. A diaphragm, a magnet, and an inductor (a coil of wire). The diaphragm and the magnet are attached to each other, while the inductor is coiled around the magnet. Since sound is a pressure wave, the pressure wave moves the diaphragm back and forth. The magnet which is attached to it also moves back and forth in and out of the inductor coil. The motion of the magnet through the coil changes the strength of the magnetic field at the inductor and this causes an electrical current to flow in the inductor.So it is not the magnet itself that converts the sound into electrical signals, it is a 3 step process.Diaphragm turns pressure waves into motionMagnet turns the motion into a changing magnetic fieldInductor turns the changing magnetic field into an electric current.
When were radio waves first discovered?
Radio waves were first discovered by German physicist Heinrich Hertz in 1888 during experiments with oscillating electrical circuits. He demonstrated the existence of electromagnetic waves and their properties, laying the foundation for the development of wireless communication.
How are light and sound alike how are they different?
They are alike in that both are waves. In physical mathematics, they can be described with partial differential equations that have a particular form, called a "wave equation." There are many particular wave equations, but they all have repeating patterns in space and time, and don't lose much energy in each cycle. The difference between light and sound is the medium in which their waves travel. Sound is a mechanical vibration. Atoms move, and the associated chemical bonds or molecules transmit the physical movement to other atoms. The motion is fastest in very rigid crystals such as diamond or steel (e.g. welded train rails). It is somewhat slower in liquids, like water, and slowest in gases, like air. In sea-level room-temperature air, sound moves at about 344 meters per second. In vacuum, with no air, sound cannot be transmitted. In each medium, there is a maximum "cutoff frequency." Beyond that number of cycles per second, the medium doesn't spring back fast enough to transmit the wave. It's about 100,000 cycles per second in air, and 12 million cycles per second in water. Sound waves can be bent by reflecting from rigid surfaces, or by arrays of tubes that slow the edges of the waves. Lower frequency sound waves can move larger, more rigid structures, so they reflect less easily from them. Frequencies below 10 cycles per second can move thin concrete walls. Light is alternating magnetic and electrical waves at right angles (90 degrees) to each other. It is made when electric charges move rapidly. When the electrical wave grows it makes the magnetic wave. When the magnetic wave moves it makes the electrical wave. Different wavelengths are different spectral colors. Light is a very short wave, from 300 nanometers (hard ultraviolet) to 2000 nanometers (far infrared). The waves move at the speed of light, about 300 million meters per second in vacuum. It moves slower when the electric fields have to move the electrons of atoms. Lenses bend the waves by slowing the edge of a wave, bending the fields. The longer (red) waves bend less easily, causing colors around the images in simple lenses. Rainbows form when light is bent by water drops. Light can also be reflected by electrical conductors (like aluminum, mercury or silver) that short-out the electric fields with moving electrons. This causes the magnetic fields to reform as mirror images going in a mirror direction. In very intense magnetic fields, conductors become transparent because the electrons can no longer move to short out the electric fields of light. In light from a hot place, like the sun or a filament light bulb, the waves are scrambled. Polarized light has the electric and magnetic components of the waves moving in the same direction. Lasers send polarized waves in lock-step (they are "coherent"), so that the electricity and magnetic fields reinforce each other. Radio waves are much longer coherent waves from a few millimeters up to thousands of meters long. x-ray and gamma rays are much shorter waves, usually more like thermal light. As the waves get shorter, more intense electric fields are needed to reflect them. x-rays cannot be reflected by ordinary metals. They are reflected by the nuclei of heavy atoms, at angles of a few degrees. All these "electromagnetic" waves are formed by moving electric charges: radio moves electrons in antennas, light moves electrons in atoms, x-rays and gamma rays are from moving particles in atomic nuclei. A human can make very long, weak radio waves just by getting a static electric charge on a comb, and waving it with their arm. Radio waves were first proven to exist with spark-gaps. Light, and gamma rays were proven to be electromagnetic because they are changed by strong electric and magnetic fields.
What is the first step in recording an impression?

How do you play superstition on guitar?
This recording is in the key of E=flat so unless you tune your guitar down a half step, it will be hard to recreate the sound. The recording also has no guitar on it, it is a clavinet keyboard.
How do you save a sound as a file on your computer?
You needa microphone (external or built in)a sound card (with microphone input if external microphone)a recording program (Windows comes with a Sound Recorder program, Mac OS X comes with a program called GarageBand)See related link for step by step instructions for Windows
How do you convert thermal into sound energy?
Two step process: First convert heat to electrical and then cpnvert electrical to sound....
When did the digital revolution begin?
in the 1950s, when government agencies began using large computers. (;
Is step a short vowel?
Yes. The E has a short E sound as in stem and pep.
Why does quick step sound effect not work sometimes in sonic generations?
its a small bug that can be fixed very easily. you have to play a classic sonic level first then when you play modern sonic level the quick step sound effect will return
What is the first step in the analyzing and recording process is to analyze each transaction and event from source documents?
The first step in the analyzing and recording process is to examine each transaction and event as documented in source documents, such as invoices, receipts, and contracts. This involves identifying the accounts affected, determining the nature of the transaction, and assessing its impact on the financial statements. Accurate analysis ensures that the subsequent recording of transactions in the accounting system reflects the true financial position of the entity. Proper analysis lays the groundwork for accurate bookkeeping and financial reporting.
What is third step in searching a detainee?
The first step is to restrain the detainee, handcuffs, leg straps, etc. The second step is to search the pockets of the detainee, in case of weapons or needles. The third step is to ensure that the detainee is safe and sound in a police cell overnight.
How do I set the recording time on my TiVo DVR?
