Ihele AMR lisebenzisa i-bitrate enjani?

I-lossy AMR ikhodwe ku-192 kbps ngokuzenzakalela. Uhlelo lwekhwalithi yomsindo lunikeza futhi 320 kbps ukuqinisekisa ukhwalithi enhle kanye ne-128 kbps ukuqinisekisa ifayela elincane. I-lossless AMR (WAV, FLAC) i ignore i-bitrate futhi igcine yonke isampula.

Ingabe i-AMR izogcina isilinganiso esifanayo sesampula njenge-WMA?

Ngokuzenzakalela yebo (48 kHz WMA → 48 kHz AMR). Uma ufuna uku-downsample ukuhambisana (isibonelo 96 kHz → 44.1 kHz yokushaya i-CD) isinqumo esiphezulu sesampula-rate sikwenza lokhu ngekhwalithi ephezulu yoku-resamply.

Ingabe ngizolungisa umsindo ku-WMA kuya ku-AMR?

Akunalokhu kulesi simo. Umguquli awunaso isilungiselelo sokulungiswa kokulungiswa futhi ushiya izinga njengelikhona. Ukwenza umsindo ulinganise, sebenzisa i-AMR eqediwe ngethuluzi lokujwayelekile kule ndawo.

Ingabe i-AMR izodlala ku-stereo yemoto yami / iPod / Sonos?

MP3 idlala cishe kuwo wonke indawo. AAC idlala ku Apple amadivayisi, Android amafoni amaningi kanye Sonos. FLAC idlala ku Sonos ne Android kodwa hhayi ku iPods older, futhi WAV idlala ku cishe konke kodwa yenza amafayela amakhulu.

Ukulayishwa kanye nokuguqulwa kwe AMR kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukuphoqa okuphelele.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-WMA libe AMR?

I-codec efanayo iphinde i-mux: imizuzwana engu-10-30. Yenza kabusha i-codec ehlukile: ngokuvamile 10-20% yesikhathi somthombo, ngakho-ke ihora WMA → AMR liphele ngemizuzu engu-6-12.
