Sound File Formats
Sound File Formats:
While recording sounds for multimedia, projects you must balance the quality of sound desired with the storage space i.e. the amount of RAM available and the capability of the sound delivery equipment. The term sampling of an analog sound signal is often is used in this context. It is a measure of the rate at which a analog sound signal is quantized to its nearest discrete value. Depending on how often these samples are taken determines the sampling rate. Sampling rate is important for reconstruction of the original signal. Closer the samples are, better is the similarity between the source and the digitized sound. Another important aspect often used is the recording resolution. The resolution determines the accuracy with which a sound can be digitized. The more bits you use in a recording, the more realistic this sound playback will be.
As far as the previous link relating to multimedia sounds are concerned, there are 2 major categories: 1: Content Sound 2: Ambient Sound
Content sound provides information to the audience, it is like a dialog in theater or films. Content sound mainly consists of : Speeches, Description of certain information like in educational packages for young children barking of a dog etc. Voice overs, these should not be confused with narrations. This type of content sound is used in instances where short guidance/ instructions are necessary to be provided for the user to maneuver through the application.
Ambient Sound preferentially implies a wide range of background and sound effects used for multimedia applications. This sound does not provide content information but creates a mood. Ambient sound is also provided to relax, calm, make a cheerful experience for the user. The following are various file formats which are popular today:
1: WAV
2: WMA
3: MP3 and its variants
4: Real Audio format
