Is there any conversion loss when converting from one format to another? I know both mp3 and ogg are lossy formats, in that some inaudible(?) detail is removed to reduce file size, so I've already lost some audio quality in the original conversion from CD. Am I losing more in converting from ogg to mp3?
Incidentally, I used ogg for most of the CDs, as I heard it was supposed to be superior to mp3. However, I have a Yamaha receiver that will only play mp3. My tablet and phone both play ogg as well as mp3.
Every conversion from one lossy format to another will result in further degradation to some extent, because the re-encoding will continue to make use of the new codec's ways of cutting out elements it considers less important. In that sense it's a bit like the digital equivalent to audio cassette tape dubbing. I'm not sure if some algorithms mitigate this effect when doing lossy -> lossy. Also there are many different settings and bitrates you can select for ogg, mp3 and some other codecs, so it depends on any options or parameters you set in the command. If you don't set any presumably it will use defaults. You should investigate what those are and try to ensure the new codec is at least as high quality as the old. gumb -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
