Ist die Klangqualit\u00e4t der Bluetooth-Kopfh\u00f6rer nicht gut? Teil 4<\/strong><\/p>\n

\"Bluetooth\"<\/p>\n

Was ist ein Bluetooth-Codec von geringer Qualit\u00e4t?<\/p>\n

\"Bluetooth\"<\/p>\n

 <\/p>\n

SBC (Sub Band Codec) ist ein Codec, der im Gegensatz zu Codecs mit hoher Klangqualit\u00e4t wie AAC, aptX, aptX HD und LDAC eine niedrige Klangqualit\u00e4t haben soll.<\/p>\n

Im Allgemeinen, laut einer drahtlosen Verbindung (Radio) offenbar in Richtung der geringen Klangqualit\u00e4t Bluetooth-Verbindung mit einer kabelgebundenen Verbindung, die das AUX-Verbindungskabel oder \u00e4hnliches Bluetooth verbindet, verloren auch flacher Klang und die Verl\u00e4ngerung der H\u00f6hen den stereoskopischen Realismus unterdr\u00fcckt, was gr\u00f6\u00dftenteils auf diesen SBC zur\u00fcckzuf\u00fchren ist.<\/p>\n

SBC, ein Codec, der als Standardunterst\u00fctzung in A2DP f\u00fcr Musikstreaming spezifiziert ist, ist zu einer Spezifikation geworden, die die Klangqualit\u00e4t aus Gr\u00fcnden wie der Reduzierung der Hardwarelast des Computers unter der damaligen Pr\u00e4misse erheblich einb\u00fc\u00dft.<\/p>\n

Obwohl die Klangqualit\u00e4t gering ist, gibt es auf der Ger\u00e4teseite nur wenige Einschr\u00e4nkungen und es wurde in verschiedene Ger\u00e4te \u00fcbernommen, so dass man sagen kann, dass es der Motor war, der die weit verbreitete Verwendung von Bluetooth vorangetrieben hat.<\/p>\n

Liste der Bluetooth A2DP-Codecs
\nVerwenden Sie die Bitrate als Index, der die Klangqualit\u00e4t bestimmt, wenn Sie die Bluetooth A2DP-Codecs in einer Liste neu anordnen,<\/p>\n

[Referenz] UKW-Radio: ca. 96 kbps
\nSBC: Da es sich um einen Standard-A2DP-Codec handelt, kann er mit allen Ger\u00e4ten verwendet werden, die Bluetooth A2DP unterst\u00fctzen. Praktisch 64 bis etwa 200 kbps.
\nAAC – Urspr\u00fcnglich das vom iTunes Store \u00fcbernommene Format. Weit verbreitet in Apple Bluetooth-Ger\u00e4ten wie iPhone und iPod. Effektiv bis zu 320 kbps.
\naptX – Derzeit von CSR Limited entwickelt, das von Qualcomm \u00fcbernommen wurde. Wirklich bis zu 384 kbps.
\naptX HD – Wie aptX, entwickelt von CSR Limited. Tats\u00e4chlich bis zu 576 kbps h\u00f6her als aptX.
\nLDAC: von Sony entwickelt. Es wird haupts\u00e4chlich verwendet, um hochwertige Tonquellen, wie beispielsweise hohe Aufl\u00f6sung, anzuschlie\u00dfen. Wirklich bis zu 990 kbps.
\n[Referenz] Medien, die komprimierte Tonquellen wie mp3 \/ AAC aufzeichnen: Fast 64 bis 320 kbps
\n[Referenz] CD (-DA): 1.411 kbps
\nWird sein. Je h\u00f6her die Zahl, desto gr\u00f6\u00dfer die Datenmenge pro Sekunde, sodass die Tonqualit\u00e4t als h\u00f6her angesehen wird. Die Bluetooth-Verbindung \u00fcber SBC betr\u00e4gt selbst unter besten Kommunikationsbedingungen ca. 200 kbps. Wenn die Kommunikationsbedingungen schlecht sind, wird die Daten\u00fcbertragungsmenge auf das \u00c4quivalent von 64 kbps reduziert und die Tonqualit\u00e4t ist niedriger als die von UKW-Radio.<\/p>\n

Beispielsweise werden im Allgemeinen gut komprimierte Tonquellendaten wie mp3 oder AAC verwendet, eine Datenmenge von etwa 256 kbps, bei Auswahl des SBC als Codec die Bluetooth-Verbindung, der Teil der Bluetooth-Verbindung aufgrund der geringen SBC-Qualit\u00e4t , es wird ein Flaschenhals.<\/p>\n

SBC hat seine Rolle bei der Popularisierung von Bluetooth bereits einigerma\u00dfen beendet. In Zukunft, wenn man bedenkt, dass die maximale Bitrate, die von allgemeinen komprimierten Tonquellen wie mp3 und AAC unterst\u00fctzt wird, 320 kbps betr\u00e4gt, AAC, aptX, aptX HD und LDAC, die qualitativ hochwertige Sound-Codecs mit einem Standard von 320 kbps oder h\u00f6her sind. , es wird m\u00f6glich sein. Ich denke, Sie sollten es so oft wie m\u00f6glich verwenden, um eine Bluetooth-Verbindung herzustellen.<\/p>\n

4 Punkte, die bei der Verwendung eines hochwertigen Bluetooth-Soundcodecs (AAC, aptX, LDAC) zu beachten sind
\nAls n\u00e4chstes m\u00f6chte ich \u00fcber die Vorsichtsma\u00dfnahmen bei der Verwendung hochwertiger Sound-Codecs beim Verbinden mit Bluetooth A2DP schreiben: AAC, aptX, aptX HD und LDAC.<\/p>\n

Generell gilt es beim Anschluss eines hochwertigen Bluetooth A2DP Soundcodecs vier Punkte zu beachten.<\/p>\n

Beide verbundenen Ger\u00e4te m\u00fcssen denselben hochwertigen Codec unterst\u00fctzen
\nAchten Sie auf andere drahtlose Verbindungsumgebungen als Bluetooth, wie z. B. WLAN und Funkwelleninterferenzen
\nAAC-Codec-Unterst\u00fctzung wie Bluetooth A2DP ist anstelle der AAC-Dateiunterst\u00fctzung erforderlich
\nBest\u00e4tigen Sie die A2DP-Codec-Auswahleinstellungen f\u00fcr die Bluetooth-Verbindung erneut<\/p>\n","protected":false},"excerpt":{"rendered":"
