Sound is one of the key elements to the success of most interactive media products such as DVD’s, Video games, without the use of sound within such products, the quality and purpose of them would fail to perform well with its audience. There are many different techniques, purposes and methods to creating and using sound in these different products.

THEORY OF SOUND Waveform (sound wave)We measure sound using decibles (dB), the amplitude is expressed by the height of the waves, when the sound is louder, the sound wave will be higher, and thus the quietest sound would be rated as zero dB. There are four main parts to a sound wave; these are frequency, wavelengths, amplitude and period. The horizontal lines within sound waves are referred to as wavelengths. Wavelengths are measured from consecutive and equal points within the sound wave. The period is the amount of time it would take for the first equivalent point to reach the second one. They call number of cycles per unit of time, frequency. Frequency is measured in hertz a.k.a Hz, as hertz display the number of cycles per second from a certain point.

They call number of cycles per unit of time, frequency. Frequency is measured in hertz a.k.a Hz, as hertz display the number of cycles per second from a certain point. If there is an increase of air pressure, the pressure within a cycle can be altered. Pitch is related to understanding the frequency, in which the brain works out, vibrations (which are used in sound) mobilize through the wavelengths, you measure these by figuring out that fast vibrations have a high frequency and pitch.

Sound only possesses the ability to travel through gas, liquid and solids making it impossible or difficult for sound to travel through such materials as, glass, plastic, or walls. Loudspeakers can be many different types of devices such as, radios and headphones, (as long as it transfers electrical energy to motorised energy, it will be considered a sound generator).

BASICS OF SOUND RECORDING SNR OR S/N (Signals to noise ratio), this is the equations that is used to find the power of signals and noise. Noise is the enemy to every recording studio, as it unwanted sound. Analogue is a signal that is continuous. Compared to digital, that
