Sound quality is the quality of the audio output from various electronic devices within your system. Sound quality can be defined as the degree of accuracy with which various audio components emits the original sound waves. Sound quality is also the physical pleasure or fatigue experienced by a listener.
In any mobile audio set-up the tonal quality of your gear, and the physical traits of the vehicle, determine SQ.
SQ is also affected by the recording techniques and equipment used, from the microphones at the session, through the pressing at the compact disc factory,
MP3's are a common audio format for consumer audio storage.The MP3 file is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11th the size of the audio file created from the original audio source. An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality. The compression works by reducing accuracy of certain parts of sound that are deemed beyond the auditory resolution ability of most people.
