  1. 1. Hi, I am Guillermo Delgado from Mexico City, first excuse me for my mistakes translating to english and my unknowledge in flash or Html5 to make a spectacular presentation, but i hope the info here could be interesting for you. In my experience i have found this four topics as elemental to know because around them we can make our productions to sound good and profesional, in this way we can improve the industry, offering to music fans the best audio quality and better music ideas, enjoy and: Thanx for reading!
  2. 2. Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there are additional modes of propagation). During their propagation, waves can be reflected, refracted, or attenuated by the medium.
  3. 3. Sound waves are often characterized by four basic qualities: Frequency Amplitude Wave Forms Phase
  4. 4. The number of cycles per unit of time is called the frequency. For convenience, frequency is most often measured in cycles per second (cps) or the interchangeable Hertz (Hz) (60 cps = 60 Hz). 1000 Hz is often referred to as 1 kHz (kilohertz) or simply '1k' in studio parlance.
  5. 5. Frequencies above and below the range of human hearing are also commonly used in computer music studios. We refer to these ranges as:
  6. 6. Amplitude is associated with the height of a sound wave and is related to volume. Amplitude is measured in decibels (dB). Most people can recognize about a 3 dB change in amplitude. An increase in amplitude is usually expressed as a “boost” and a decrease in amplitude is often expressed as a “cut ”.
  7. 7. Waveform defines the size and shape of a sound wave. Sound can come in different waveforms, other than a sine wave. Other common waveforms include triangle, square, and saw tooth waves. Each waveform has its own sound and characteristics and each may be used for different applications.
  8. 8. Phase designates a point in a sound wave's cycle and is also related to frequency. It is measured in degrees and is used to measure the time relationship between two or more sine waves. when two sound waves are in phase, the result is increased amplitude. When they are 180 degrees out of phase, they can completely cancel each other resulting in little or no sound.
