\"MP3\"<\/p>\n

Die drei Bytes, die bei 1397H beginnen, sind 54 41 47, die das “TAG”-Zeichen speichern, das anzeigt, dass diese Datei ID3 V1.0-Informationen enth\u00e4lt.<\/p>\n

\"MP3\"<\/p>\n

Die 30 Bytes, die bei 139AH beginnen, speichern den Namen des Songs, die ersten 4 Bytes, die nicht 00 sind, sind 54 45 53 54, was “TEST” bedeutet;
\ndie 4 Bytes beginnend bei 13F4H sind 04 19 14 03 und das Jahr der Speicherung ist “04\/25\/2003” \u201d;
\ndas letzte Byte ist 4E, was die Musikkategorie darstellt, und der Codename ist 78, also \u201eRock&Roll\u201c; das
\nandere Bytes sind alle 00 und es werden keine Informationen gespeichert.<\/p>\n

4. Schlussfolgerung
\nAls wichtiger Multimedia-Datentyp suchen die Menschen immer nach effizienteren Komprimierungsmethoden und neuen Audiodateiformaten. In der MP3-Datei wird die MDCT-Transformation verwendet, bei der es sich um eine quasi-optimale Transformation mit einfacher Struktur und einfacher Programmierung handelt, die das Problem vermeidet, dass die optimale Transformation (KL) f\u00fcr die Eigenwerte und Eigenvektoren der schwer aufzul\u00f6sen ist Kovarianz. Matrix.<\/p>\n

Durch die Analyse des MP3-Dateiformats ist es nicht schwierig, seine M\u00e4ngel zu finden. Jeder Frame einer MP3-Datei hat den gleichen 4-Byte-Frame-Header, was f\u00fcr eine MP3-Datei mit einer gro\u00dfen Anzahl von Frames etwas Speicherplatz erfordert. ID3 speichert die Musikbeschreibungsinformationen. Die Eigentums-, Copyright- und andere Informationen im Frame-Header sind ebenfalls Beschreibungsinformationen. Die Musikbeschreibungsinformationen sind etwas chaotisch.<\/p>\n

Die Entwicklung von MP3 ist jedenfalls nicht aufzuhalten. MP3 ist zu einem anerkannten Tondatenformat geworden. MP3 entwickelt sich neben JPEG-Bildern und PDF-Dokumenten zu einem Hot Spot im Bereich der multimedialen Informationsverarbeitung.<\/p>\n","protected":false},"excerpt":{"rendered":"
