Wie funktionieren MP3-Player?<\/h2>\n

\"Mp3<\/p>\n

Projekt: MP3-Player<\/p>\n

\"Mp3<\/p>\n

Der vollst\u00e4ndige Name von MP3 lautet MPEG Audio Layer 3. Das MPEG-Komprimierungsformat ist eine Reihe von Standards f\u00fcr Bilder und T\u00f6ne, die von der Motion Picture Experts Group formuliert wurden.<\/p>\n

MP3 ist ein Audioformat zum Komprimieren von Tonsignalen. Signalkomprimierungsformatstandard. Die Abtastfrequenz der CD betr\u00e4gt 44,1 MHz, 16 Bit und das Datenvolumen 1,4 Mbit \/ s, w\u00e4hrend das entsprechende MP3-Datenvolumen nur 112 kbps oder 128 kbps betr\u00e4gt, was 1\/12 des urspr\u00fcnglichen Datenvolumens entspricht.<\/p>\n

Das hei\u00dft, es gibt eine sehr wichtige Variation in der Bitrate zwischen einer CD und einer mp3. Mit einem Verh\u00e4ltnis von 1\/12, was mehr oder weniger dem Verh\u00e4ltnis zwischen seiner Gr\u00f6\u00dfe entspricht. Hass nimmt diesen Unterschied aber bekanntlich nicht wahr, solange das mp3 eine Bitrate von 128 kbps oder h\u00f6her verwendet.<\/p>\n

Eine herk\u00f6mmliche CD kann jetzt die 10-fache oder mehr Kapazit\u00e4t von Musik speichern, aber im menschlichen Ohr ist die Wirkung von Musik nicht anders.<\/p>\n

Das Funktionsprinzip des MP3 Walkman ist wirklich sehr einfach: Er verwendet den Steuerchip (CPU) zur Steuerung des Decoder-Chips und des LCD-Bildschirms, und der Decoder-Chip decodiert die MP3-Datei oder Datei im WMA-Format im eingebauten oder externen Flash-Speicher Flash-Speicherkarte, dann die Digital-Analog-Wandlung und schlie\u00dflich die Ausgabe \u00fcber die Kopfh\u00f6rer.
\nMP3-Player verwenden den digitalen Signalprozessor DSP (Digital Signal Processor), um die Aufgabe der Streaming-Verarbeitung und Dekodierung von MP3-Dateien zu erf\u00fcllen. DSP ist f\u00fcr die Walkman-Daten\u00fcbertragung, die Ger\u00e4teschnittstellensteuerung, die Dateidecodierung und -wiedergabe sowie andere Aktivit\u00e4ten zust\u00e4ndig. Der DSP kann eine Vielzahl von Verarbeitungsaufgaben in sehr kurzer Zeit erledigen und dieser Prozess verbraucht sehr wenig Strom (dies ist auch ein Unterscheidungsmerkmal f\u00fcr seine Eignung f\u00fcr tragbare Player).
\nExtrahieren Sie zuerst die MP3-Songdatei aus dem Speicher und lesen Sie das Signal im Speicher aus \u2192 dekodieren Sie das Signal im Dekodierchip \u2192 wandeln Sie das dekodierte digitale Signal durch den Digital-Analog-Wandler in ein analoges Signal um \u2192 und verst\u00e4rken Sie dann das konvertierte analoge Audiosignal \u2192 Nachher Tiefpassfilterung, es geht zum Kopfh\u00f6rerausgang und der Ausgang ist die Musik, die wir h\u00f6ren.<\/p>\n","protected":false},"excerpt":{"rendered":"
