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. 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. added "Set This Image as a Folder Cover Art" button to "Folder cover art" panel (visible only when "Show first existing image in "Folder cover art" if folder.jpg does not exists" enabled and current image file is not a folder.MP3 tags are metadata about the MP3 file that conveys information about the artist, track number, album, album cover, year, and genre.added "Set tag image as folder cover art" button to "File cover art" panel.added "Tags cover art resizing" options to program options -> Tags.added "Delete folder cover art" button to "Folder cover art" panel. added "Resize Files Cover Art" and "Resize Folders Cover Art" function to "Tools" menu. This is a must have software for any mp3 or mp4 player owner. Tag&Rename supports many files and tags standards in an easy and intuitive way, so you can work with music metadata and not have to think about files codecs and tags versions - Tag&Rename does it all.
