Warum sind MP3-Bitraten oft Vielfache von 32? (Potenz von 2)<\/h2>\n

\"MP3<\/p>\n

Manche Leute sagen:<\/p>\n

\"MP3<\/p>\n

Ich verstehe, warum Vielfache von 2 h\u00e4ufig auf Computern angezeigt werden, da sie bin\u00e4r sind, aber ich kann nicht herausfinden, wie die g\u00e4ngigsten MP3-Bitraten (64 kbps, 128 kbps, 160 kbps, 192 kbps, 256 kbps, 320 kbps usw.) auch dazu neigen, dem zu folgen Regel.<\/p>\n

Da MP3 nur eine sequentielle Kodierung von Schallwellen ist, warum ist es wichtig, jede Sekunde in Kilobit darzustellen, die durch 2 teilbar sind?
\nLiest ein Musikplayer wie iTunes die Datei weiter und spielt den codierten Ton unabh\u00e4ngig vom Sekundenlimit ab, oder liest er die Datei jede Sekunde?
\nIm letzteren Fall erfordert das Lesen einer 256-kbps-Datei das Lesen von etwas weniger Speicherseiten als eine 257-kbps-Datei, aber der Player kann unabh\u00e4ngig von ihrer Bitrate immer 256-KB-Bl\u00f6cke lesen und sie einfach automatisch verarbeiten.
\nSind 128-kbps-MP3-Songs beliebt, nur weil es eine allgemein akzeptierte Bitrate ist, oder haben sie wirklich irgendwelche Vorteile gegen\u00fcber 126-kbps- und 131-kbps-Dateien, abgesehen von einem sehr geringen Unterschied in Qualit\u00e4t\/Dateigr\u00f6\u00dfe?<\/p>\n

F\u00fcr die Codierung mit konstanter Bitrate (CBR) spezifiziert der Standard MPEG-1 Audio Layer III Standardbitraten von 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 und 320 kbit \/zweite. Es gibt ein paar andere, die im MPEG-2-Standard definiert sind, aber sie sind auch Vielfache von 2 (eigentlich alle Vielfachen von 8 im Bereich von 8 bis 160 – siehe die Tabelle “Bitrate Index” im obigen Link).<\/p>\n

Technisch gesehen gibt es nichts, was die MP3-Bitrate auf ein Vielfaches von 2 begrenzt, da eine Codierung mit variabler Bitrate verwendet werden kann oder eine benutzerdefinierte Bitrate erreicht werden kann, indem einige Flags verwendet werden, die nicht in der MPEG-Spezifikation verwendet werden (obwohl dies manuell implementiert werden muss). . Damit MP3 MPEG-kompatibel und daher mit den meisten MP3-Decodern kompatibel ist, muss es eine durch die Spezifikation definierte Bitrate haben, sodass alle CBR-codierten MP3-Dateien eine Bitrate von zwei haben.<\/p>\n","protected":false},"excerpt":{"rendered":"
