![]() ![]() Of course, it is possible to manually go through your music collection and add missing tags or edit those that are incorrect. The tracks you purchase online should be correctly tagged, but this is not necessary the case for those that you rip yourself. But being able to do this is dependent on having the correct information attached to files so that it can be successfully searched. The opposite of lossy compression is lossless compression, where data is compressed using algorithms that can perfectly reconstruct the original data using the compressed data.One of the great benefits of working with digital music files is that metadata makes it possible to perform advanced searches, as well as benefiting from high quality audio. The more the file is compressed, the lesser the sound quality. However, because lossy compression reconstructs only an approximation of the original data, the sound quality of the file may degrade. So, lossy compression aims to delete the frequencies that the people can’t hear anyway. ![]() The human ear is not capable of hearing all audio frequencies, they can generally only hear sound from 20Hz to 20kHz. In lossy compression, the partial deletion of data is based on psychoacoustics. It uses lossy compression to discard some parts of the data, resulting in a significant reduction in file size. MP3 files are basically compressed audio files. ![]() DID YOU KNOW?ĭid you know that MP3 stands for MPEG-1 (or MPEG-2) Audio Layer III? MPEG stands for Moving Picture Experts Group, the team that designed the MP3 format in 1993. The ID3 can be found within the MP3 file itself and takes up 128 bytes of space. “ID3” stands for “IDentify an MP3,” and it was developed in 1996 by Eric Kemp. This data is encoded in a “container” called ID3, which stores the information in a standard format. MP3 tags are metadata about the MP3 file that conveys information about the artist, track number, album, album cover, year, and genre. ![]()
