MP3äänitiedostot

MP3äänitiedostot refer to audio files encoded using the MP3 (MPEG-1 Audio Layer III) compression format. This format is a widely adopted standard for digital audio compression, known for its ability to reduce the size of audio files significantly while maintaining a relatively high level of perceived audio quality. The compression process works by intelligently removing parts of the audio signal that are less audible to the human ear, a technique known as perceptual coding.

The MP3 format was developed by the Moving Picture Experts Group (MPEG) and became popular in the late 1990s and early 2000s with the rise of the internet and portable digital music players. Its widespread adoption led to a revolution in how music was distributed and consumed. MP3 files are characterized by their `.mp3` file extension. The quality of an MP3 file is often determined by its bitrate, which is measured in kilobits per second (kbps). Higher bitrates generally result in larger file sizes but also better audio fidelity. Common bitrates range from 128 kbps to 320 kbps. While more advanced audio codecs exist today, MP3 remains a prevalent format due to its legacy support across a vast array of devices and software.
