Kodi kusinthidwa kwa WMA ku AMR ndi gawo lachiwiri la kutsitsa kwa lossy?

Yes, and it's worth planning around. Both formats are lossy, so the AMR encoder is working from audio that has already been through one psychoacoustic pass, and its own decisions compound the first set. At 192 kbps or above the result is still transparent for most listening. If you have a lossless master anywhere, encoding the AMR from that instead avoids the double pass entirely. WMA ndi lossy mwa default, mu ASF chidebe, ndi lossless ndi mawu-optimised mitundu yomwe ndi yosadziwika anakumana. AMR ndi narrowband mawu codec kuyendetsa pakati pa 4.75 ndi 12.2 kbps, modeling munthu woimba m'mimba kuposa wonse audio spectrum.
