Is it possible to compress a mp3 to an ogg file?
It is possible to
convert a MPEG Layer-III encoded Wave to an OGG Vorbis encoded Wave with certain utilities, but I wouldn't reccomend it. Â All said utilities essentially decompress the MP3-encoded file back to the Wave format, and then re-encodes that wave as an OGG Vorbis-encoded file. Â However, since both MP3 and OGG are lossy formats you lose quality of the wave (1) with the original MP3 and (2) again with the new OGG. Â While OGGs are smaller than MP3s at comparable bitrates, and have lightly better quality at the same rates, you
will lose sound quality from the original MP3 with this method. Â That is the nature of lossy compression.
or to compress a mp3 back to a wav file and then to compress it with mo3 ?
First, to clear up the vocabulary a little. Â Converting an MP3-encoded file back to the Wave format is called
decompressing or
decoding. Â Secondly, MO3s are not simply compressed Waves. Â MO3s are music
modules in which the
samples have been encoded using MP3, OGG, or lossless compression. Â MO3 is not a stream compression, like MP3 and OGG.
