I just started experimenting with ffmpeg and was wondering if the sound quality is maintained during conversion. I converted an ogg file to mp3 and see the mp3 is smaller. Did I lose audio quality in the process?
tnx jk
Almost certainly you lost quality. Any conversion to a lossy encoding will lose quality, but I suspect you knew that. The key is to maintain at least as high a quality setting in the target format as you had in the source. Since MP3 is usually larger than the same quality Ogg, and since your mp3 is smaller, I suspect you lost even more quality than normal. You may or may not be able to here the difference, depending on the age of your ears, but still the loss is there. Google Music has standardized on 320k bps for mp3 music because it is scientifically known to exceed the range of human hearing (by at least half again), and therefore nobody can complain about quality. However the debate rages on about different encodings. Google 320 kbps vs ____ and you get a lot of hits. In general Ogg/Vorbis fairs decidedly better regarding the quality/bitrate ratio, allowing lower bit-rates. But jeeze, disk is cheap these days, so why bother chasing smaller files?
