Abtastrate und Bitrate von MP3 Teil 2<\/h2>\n

\"BIT<\/p>\n

Die Anzahl der Ziffern im Sound entspricht der Anzahl der Farben auf dem Bildschirm und gibt die Datenmenge pro Sample an.<\/p>\n

\"bit<\/p>\n

Je gr\u00f6\u00dfer die Datenmenge ist, desto genauer ist nat\u00fcrlich der Wiedergabeton, um den Ton nicht zu verwirren. der Teekanne mit der Zugpfeife. Ebenso ist es klarer und pr\u00e4ziser f\u00fcr das Bild, um Blut und Ketchup nicht zu verwechseln. [Begrenzt durch die Funktion menschlicher Organe sind 16-Bit-Ton und 24-Bit-Bild jedoch im Grunde die Grenzen gew\u00f6hnlicher Menschen, und die h\u00f6heren Ziffern k\u00f6nnen nur von Instrumenten unterschieden werden. Das Telefon hat beispielsweise 7-Bit-Sound, der mit 3 kHz gesampelt wurde, und die CD hat 16-Bit-Sound, der mit 44,1 kHz gesampelt ist, sodass die CD klarer ist als das Telefon. ]<\/p>\n

Wenn Sie die beiden oben genannten Konzepte verstehen, ist die Bitrate leicht zu verstehen. Nehmen Sie das Telefon als Beispiel, 3000 Samples pro Sekunde, jedes Sample hat 7 Bit, dann betr\u00e4gt die Bitrate des Telefons 21000. Und die CD hat 44100 Samples pro Sekunde, zwei Kan\u00e4le, jedes Sample ist 13-Bit-PCM-codiert, also das CD-Bit betr\u00e4gt 44100*2*13=1146600, was bedeutet, dass das CD-Datenvolumen pro Sekunde etwa 144 KB betr\u00e4gt. Die Kapazit\u00e4t einer CD betr\u00e4gt 74 Minuten gleich 4440 Sekunden, was 639360 KB = 640 MB entspricht.<\/p>\n

Schall ist eigentlich eine Art Energiewelle, also hat er auch die Eigenschaften von Frequenz und Amplitude, wobei die Frequenz der Zeitachse und die Amplitude der Pegelachse entspricht. Die Welle ist unendlich glatt, und die Saite kann als aus unz\u00e4hligen Punkten bestehend betrachtet werden. Da der Speicherplatz relativ begrenzt ist, m\u00fcssen beim Prozess der digitalen Codierung die Punkte der Zeichenfolge abgetastet werden. Der Abtastprozess besteht darin, den Frequenzwert eines bestimmten Punktes zu extrahieren. Je mehr Punkte in einer Sekunde extrahiert werden, desto umfangreichere Frequenzinformationen k\u00f6nnen nat\u00fcrlich erhalten werden. Um die Wellenform wiederherzustellen, m\u00fcssen zwei Abtastpunkte in einer Schwingung vorhanden sein.Die h\u00f6chste wahrnehmbare Frequenz betr\u00e4gt 20 kHz, um also die H\u00f6ranforderungen des menschlichen Ohrs zu erf\u00fcllen, mindestens 40.000 Abtastungen pro Sekunde, ausgedr\u00fcckt bei 40 kHz, und diese 40 kHz ist die Abtastrate. Unsere gemeinsame CD hat eine Abtastrate von 44,1 kHz. Es reicht nicht aus, nur Frequenzinformationen zu haben, wir m\u00fcssen auch den Energiewert dieser Frequenz erhalten und quantifizieren, um die St\u00e4rke des Signals darzustellen. Die Anzahl der Quantisierungsstufen ist eine ganzzahlige Potenz von 2, und die Sample-Gr\u00f6\u00dfe unseres gemeinsamen CD-Bits betr\u00e4gt 16 Bit, also 2 hoch 16. Sample-Gr\u00f6\u00dfe ist schwerer zu verstehen als Bitrate es scheint abstrakt.Ein einfaches Beispiel: Angenommen, eine Welle wird 8-mal abgetastet, und die Energiewerte, die den Abtastpunkten entsprechen, sind A1-A8, aber wir verwenden nur eine 2-Bit-Abtastgr\u00f6\u00dfe, daher k\u00f6nnen wir nur beibehalten die 4-Punkt-Werte in A1-A8 und verwerfen die anderen 4. Wenn wir die 3-Bit-Abtastgr\u00f6\u00dfe verwenden, werden alle 8-Punkt-Informationen aufgezeichnet. Je h\u00f6her die Werte f\u00fcr Abtastrate und Abtastgr\u00f6\u00dfe, desto n\u00e4her kommt die aufgezeichnete Wellenform dem Originalsignal.<\/p>\n","protected":false},"excerpt":{"rendered":"
