Gwiritsani ntchito WAV Mafunso Ofala
Kodi Gwiritsani ntchito WAV imasintha bwanji kuchuluka kwa kusewera?
+
Concretely, nthawi-kutalika ndi kuchitidwa kwa PCM mogwirizana ndi analemba m'mbuyo losslessly, amene ndi chifukwa chake lossless chiyambi ndi lamulo lowonjezera kwa chilichonse pamwamba pa za 1.5x pamene artefacts ayamba kusonyeza. Choose a multiplier — 0.5x for half speed, 2x for double — and the whole file is retimed.
Sichoncho. Time-m'mphepete amateteza mtunda, kotero 1.5x mawu track amawoneka ngati munthu ameneyo akulankhula mofulumira kuposa monga chipmunk. Izi ndi kusiyana pakati pa bwino time-m'mphepete ndi kungosewera samples mofulumira.
Kodi mtundu woyamba amakhudza zotsatira?

Ichi ndicho. WAV ndi PCM uncompressed: bit-exact ndi editable, pa pafupifupi 10 MB pa stereo mphindi. Izi zimatsimikizira ngati zotsatira zosinthidwa zitha kusindikizidwanso mofulumira kapena kuti ziyenera kusinthidwanso mokwanira.
Pali china chilichonse chokhudza WAV apa?

Yes — WAV ndi PCM raw, kotero kusintha ndi sample-kuyenera ndi nthawi yomweyo, koma fayilo ndi za 10 MB pa stereo mphindi ndi uploads kuchititsa nthawi. Kuyenera kudziwa kuti musanayambe kusintha kwamphamvu kwakukulu.
Kutalika kwa 0.75x mpaka 2x ndi kokwanira kuti mawu azimvetsera. Kupitilira 2.5x, ma artefacts a stretch amawoneka pa chilichonse, ndipo pansi pa 0.5x, kubwezeretsedwanso kumafunika kuyambitsa zinthu zambiri. Mzimu umatha kukana zinthu zambiri kuposa mawu.
Mfupi, yeah, ndi m'madera ofanana - mphindi imodzi ya audio pa 1.5x ndi mphindi makumi awiri. Fayilo amakula ndi pafupifupi m'madera ofanana chifukwa pali zinthu zochepa kuti encode. The bitrate, the sample rate ndi channel layout onse ali kumbuyo mofananamo monga iwo anali.
Kodi ndingapeze chiyani pa Gwiritsani ntchito WAV?
+
WAV, FLAC ndi AIFF, pa iliyonse bit m'lifupi ndi sampling mtengo mpaka ndi kuphatikizapo 24-bit / 192 kHz. Lossy owona ntchito mu chimodzimodzi batani ngati inu ndinu kuphatikizira zigawo.
Kodi pali malire a kukula kwa fayilo pa Gwiritsani ntchito WAV?
+
Yesani: maakaunti aulere amapanga ma audio mpaka ku 200 MB pa fayilo - kwa PCM yosasinthika yomwe ndi pafupifupi maola makumi awiri a stereo ya CD-quality, chifukwa chake ndi chida chabwino kwambiri panjira yomwe siyingakhale ya MP3.Ngati muli pamwamba pa izi, kusintha kwa WAV kupita ku FLAC koyamba ndi kotetezeka - sichiwononga ndipo chimachepetsa kukula kwake.
