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

De drie bytes die beginnen bij 1397H zijn 54 41 47, waarin het “TAG”-teken is opgeslagen, wat aangeeft dat dit bestand ID3 V1.0-informatie bevat.<\/p>\n

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

De 30 bytes die beginnen bij 139AH slaan de naam van het nummer op, de eerste 4 bytes die geen 00 zijn, zijn 54 45 53 54, wat “TEST” betekent;
\nde 4 bytes beginnend bij 13F4H zijn 04 19 14 03 en het jaar van opslag is “25-04-2003” \u201d;
\nde laatste byte is 4E, die de muziekcategorie vertegenwoordigt, en de codenaam is 78, dat wil zeggen “Rock&Roll”; de
\nandere bytes zijn allemaal 00 en er wordt geen informatie opgeslagen.<\/p>\n

4. Conclusies
\nAls belangrijk multimedia-gegevenstype zijn mensen altijd op zoek naar effici\u00ebntere compressiemethoden en nieuwe geluidsbestandsindelingen. In het MP3-bestand wordt de MDCT-transformatie gebruikt, wat een quasi-optimale transformatie is met een eenvoudige structuur en eenvoudige programmering, waardoor het probleem wordt vermeden dat de optimale transformatie (KL) moeilijk op te lossen is voor de eigenwaarden en eigenvectoren van de covariantie. Matrix.<\/p>\n

Door de analyse van het MP3-bestandsformaat is het niet moeilijk om de tekortkomingen ervan te vinden. Elk frame van een MP3-bestand heeft dezelfde 4-byte frameheader, wat wat extra ruimte vereist voor een MP3-bestand met een groot aantal frames. ID3 slaat de muziekbeschrijvingsinformatie op. De eigendoms-, copyright- en andere informatie in de framekop is ook beschrijvingsinformatie. De informatie over de muziekbeschrijving is een beetje rommelig.<\/p>\n

De ontwikkeling van MP3 is in ieder geval niet te stoppen. MP3 is een erkend formaat voor geluidsgegevens geworden. MP3 wordt een hotspot op het gebied van multimedia-informatieverwerking, samen met JPEG-afbeeldingen en PDF-documenten.<\/p>\n","protected":false},"excerpt":{"rendered":"
