MP3

Was ist MP3?

MP3 (MPEG-1 Audio Layer III) ist ein verlustbehaftetes Audio-Komprimierungsformat, das die Dateigröße reduziert, indem es Geräusche entfernt, die das menschliche Ohr am wenigsten wahrnimmt, und dabei Kompressionsverhältnisse von 10:1 mit nahezu CD-Qualität erreicht.

What is it?

MP3 (MPEG-1 Audio Layer III) ist ein Audio-Codierungsformat, das von der Fraunhofer-Gesellschaft entwickelt und 1993 standardisiert wurde. Es verwendet psychoakustische Kompression - das Entfernen von Audiofrequenzen, auf die das menschliche Gehör am wenigsten empfindlich reagiert - um dramatische Dateigrößenreduzierungen zu erreichen.

MP3 ist das am weitesten verbreitete Audioformat in der Geschichte. Eine 128 kbps MP3-Datei ist ungefähr 10 Mal kleiner als die entsprechende unkomprimierte WAV-Datei, mit einer Qualität, die die meisten Hörer im beiläufigen Hören nicht vom Original unterscheiden können.
