Sampling and Bitrate

In Songs and How It Changes Size and Quality

What is Sampling?

Sample rate refers to the number of samples taken each second. In music, sampling is the act of taking a portion, or sample, of one sound recording. It does this with sample rate, the higher the sample rate the higher the quality of the sound file and the bigger the size of the sound file. The sound rate samples in hertz, like clock speed, the more hertz better the sound and the bigger the file. If the sound wave is sampled at a lower rate, this can lower the quality of the sound file but this means the file will be smaller. This effects the speed of download, upload and sharing because the file is more Mb. Sound is stored in computers by taking samples of the sound waves at regular intervals, converting those into binary numbers. Computers play the sound by reversing the process.

What is Bitrate?

the bitrate refers to the amount of bits used to store the different levels of sound at each sampling interval. In computing, bitrate is the number of bits that are conveyed or processed per unit of time. Bitrate is also measured in hertz, like clock speed. The higher the bitrate the higher the quality of the sound file and the bigger the file is eg 8bit instead of 16bit. This effects the speed of download, upload and sharing because the file is more Mb. The more bits, the greater range of levels that can be distinguished.
