In order to listen to MP3 files, you had to have a program that could play them. People built and maintained large personal music libraries that would have required entire rooms to house during the vinyl era.īut the MP3 was not free for anyone to use, however. The compression algorithm allowed music lovers to store tens of thousands of songs on devices that previously could only hold a few hundred. This algorithm became the MP3 file format. The result is an efficient algorithm that produces much smaller audio files though with some loss in quality in the process. Their algorithm identifies parts of the audio that are beyond the range of normal human hearing and removes those parts. ![]() The engineers at the Fraunhofer Institute hit on the solution: a type of compression algorithm that could make audio files smaller without losing sound quality.
