An explanation of MP3 and WAV
MP3 is a compressed, lossy*, digital audio format that was designed to greatly reduce the amount of data required to represent an
audio signal. When compressing the audio signal, it discards portions that are considered less important to the human ear. Through
this process, compressed audio can be stored at 1/10 the size of uncompressed audio. Since the introduction of the MP3 audio format,
it has become widely popular, especially on the internet. Users can easily store high-quality MP3s on their computers without sacrificing
lots of disk space. Also, with modern software capabilities, these files can be easily burned onto blank CD media.
WAV is a high-quality lossless* digital audio format. Although WAV is a popular format, it isn’t the most convenient for computer-to-computer
transfer as their high quality results in very large files, depending on the length of the audio signal recorded. This format is commonly
used by professionals or audio experts who demand the highest quality audio for their purposes.
*In lossless compression formats, all the samples from the audio signal is preserved in order to create the highest quality reproduction
possible. In lossy compression formats, only the portion of the audio signal is sampled. In many cases, the difference between lossless
and lossy formats can’t be detected by the human ear, making lossy compression acceptable to the average listener. For those concerned
with the highest quality audio, WAV format is preferable. For those concerned with good quality audio and conservation of disk
space, MP3 is preferable.
