MP3-Abtastrate und Bitrate<\/h2>\n

\"Bit<\/p>\n

Wenn wir mp3 h\u00f6ren und Filme ansehen, werden wir zwei Parameter bemerken.<\/p>\n

\"BIT<\/p>\n

Die gebr\u00e4uchlichsten sind eine Abtastrate von 44,1 KHz und eine Bitrate von 192 Kbps.Was ist also die Abtastrate und was ist die Bitrate? Was ist die Beziehung zwischen ihnen? Erkl\u00e4ren:<\/p>\n

Der Prozess der Umwandlung eines analogen Audiosignals in ein digitales Audiosignal wird als Sampling bezeichnet. Kurz gesagt, wie viele Datenpunkte braucht man, um einen 1 Sekunde langen Ton per Wellenform-Sampling aufzunehmen. Beispiel: Die Tonabtastrate von 44,1 KHz entspricht dem Verbrauch von 44.000 Datenpunkten, um die Tonwellenform f\u00fcr 1 Sekunde zu beschreiben. Grunds\u00e4tzlich gilt: Je h\u00f6her die Abtastrate, desto besser die Klangqualit\u00e4t; Die Abtastfrequenz wird im Allgemeinen in drei Stufen unterteilt: 22,05 kHz, 44,1 kHz und 48 kHz; 22,05 KHz k\u00f6nnen nur FM-Radio-Klangqualit\u00e4t erreichen, und 44,1 KHz ist die theoretische Grenze der CD-Klangqualit\u00e4t, 48 KHz hat DVD-Qualit\u00e4t erreicht.<\/p>\n

Die Abtastrate bezieht sich auf die Abtastfrequenz bei der Umwandlung von Ton (analoges Signal) in mp3 (digitales Signal), dh wie viele Datenpunkte pro Zeiteinheit abgetastet werden. (Die Daten f\u00fcr einen Abtastpunkt sind 8 (oder sogar mehr) Bits lang.)<\/p>\n

Die Bitrate bezieht sich auf die Anzahl der Bits (Bits), die pro Sekunde \u00fcbertragen werden. Die Einheit ist bps (Bit pro Sekunde). Je h\u00f6her die Bitrate, desto mehr Daten werden \u00fcbertragen und desto besser ist die Tonqualit\u00e4t.<\/p>\n

Man kann sagen, dass die Abtastrate und die Bitrate wie die horizontalen und vertikalen Koordinaten auf der Koordinatenachse sind. Die Abtastfrequenz auf der Abszisse repr\u00e4sentiert die pro Sekunde abgetasteten Datenpunkte. Die Bitrate auf der Ordinate repr\u00e4sentiert die Genauigkeit bei der Quantisierung analoger Gr\u00f6\u00dfen mit digitalen Gr\u00f6\u00dfen.<\/p>\n

Die Abtastrate ist \u00e4hnlich wie die Anzahl der Frames von bewegten Bildern. Beispielsweise betr\u00e4gt die Abtastrate von Filmen 24 Hz, die Abtastrate des PAL-Formats 25 Hz und die Abtastrate des NTSC-Formats 30 Hz. Wenn wir Standbilder wiedergeben, die mit der gleichen Rate wie die Abtastfrequenz abgetastet wurden, wir sehen ein kontinuierliches Bild. Wenn eine mit einer Abtastrate von 44,1 kHz aufgenommene CD mit der gleichen Rate wiedergegeben wird, ist auf die gleiche Weise ein kontinuierlicher Ton zu h\u00f6ren. Je h\u00f6her die Abtastrate, desto koh\u00e4renter wird nat\u00fcrlich der Ton geh\u00f6rt und das Bild gesehen. [Nat\u00fcrlich ist die Abtastrate, die menschliche H\u00f6r- und Sehorgane unterscheiden k\u00f6nnen, begrenzt, die im Grunde h\u00f6her ist als bei 44,1 kHz abgetasteter Ton, und die meisten Menschen haben den Unterschied nicht bemerkt. ]<\/p>\n","protected":false},"excerpt":{"rendered":"
