MP3-samplefrequentie en bitsnelheid<\/h2>\n

\"Bit<\/p>\n

Wanneer we naar mp3 luisteren en films kijken, zullen we twee parameters opmerken.<\/p>\n

\"BIT<\/p>\n

De meest voorkomende zijn 44,1 KHz sample rate en 192 Kbps bit rate. Dus wat is de sample rate en wat is de bitrate? Wat is de relatie tussen hen? Uitleggen:<\/p>\n

Het proces van het omzetten van een analoog audiosignaal naar een digitaal audiosignaal wordt sampling genoemd. In een notendop, hoeveel datapunten zijn er nodig om een \u200b\u200bgeluid van 1 seconde op te nemen via golfvormsampling. Bijvoorbeeld: de geluidssamplefrequentie van 44,1 KHz komt overeen met het besteden van 44.000 datapunten om de geluidsgolfvorm gedurende 1 seconde te beschrijven. In principe geldt: hoe hoger de samplefrequentie, hoe beter de geluidskwaliteit; bemonsteringsfrequentie is over het algemeen verdeeld in drie niveaus: 22,05 KHz, 44,1 KHz en 48 KHz; 22,05 KHz kan alleen de geluidskwaliteit van FM-radio bereiken, en 44,1 KHz is de theoretische limiet van de geluidskwaliteit van cd’s, 48 \u200b\u200bKHz heeft de dvd-kwaliteit bereikt.<\/p>\n

Bemonsteringsfrequentie verwijst naar de bemonsteringsfrequentie bij het converteren van geluid (analoog signaal) naar mp3 (digitaal signaal), d.w.z. hoeveel datapunten worden gesampled per tijdseenheid. (De gegevens voor een bemonsteringspunt zijn 8 (of zelfs meer) bits lang.)<\/p>\n

Bitsnelheid verwijst naar het aantal bits (bits) dat per seconde wordt verzonden. De eenheid is bps (bits per seconde). Hoe hoger de bitrate, hoe meer gegevens worden verzonden en hoe beter de geluidskwaliteit.<\/p>\n

Het kan worden gezegd dat de bemonsteringssnelheid en bitsnelheid vergelijkbaar zijn met de horizontale en verticale co\u00f6rdinaten op de co\u00f6rdinatenas. De bemonsteringsfrequentie op de abscis vertegenwoordigt de gegevenspunten die per seconde worden bemonsterd. De bitsnelheid op de ordinaat vertegenwoordigt de precisie bij het kwantificeren van analoge grootheden met digitale grootheden.<\/p>\n

De samplefrequentie is vergelijkbaar met het aantal frames van bewegende beelden. De bemonsteringsfrequentie van films is bijvoorbeeld 24 Hz, de bemonsteringsfrequentie van het PAL-formaat is 25 Hz en de bemonsteringsfrequentie van het NTSC-formaat is 30 Hz. Wanneer we stilstaande beelden afspelen die zijn gesampled met dezelfde snelheid als de bemonsteringsfrequentie, we zien een doorlopend beeld. Op dezelfde manier is er een continu geluid hoorbaar wanneer een CD die is opgenomen met een bemonsteringsfrequentie van 44,1 kHz met dezelfde snelheid wordt afgespeeld. Het is duidelijk dat hoe hoger de samplefrequentie, hoe coherenter het geluid zal worden gehoord en het beeld zal worden gezien. [Natuurlijk is de bemonsteringssnelheid die menselijke auditieve en visuele organen kunnen onderscheiden beperkt, wat in wezen hoger is dan geluid gesampled op 44,1 kHz, en de meeste mensen hebben het verschil niet opgemerkt. ]<\/p>\n","protected":false},"excerpt":{"rendered":"
