MP3/OGG to MO3 or better
« on: 16 Mar '03 - 09:42 »
Hi.
Is it possible to compress a MP3/OGG to MO3?
Or do you know to which format I could compress a MP3/OGG to get a lower space but still a quality about 128kb?

Please reply.

Thanks

MO3 is the compression of module format songs and NOT the compression of MP3/OGG.  Module formats hold samples in WAV format, these are what MO3 compresses with OGG or MP3 algorithms.  MP3 and OGG are already a (lossy) compression, You can't really get lower than that.  If you need 128kbitps, then you'll get the size of files you get, live with it.

Thanks for your reply.

or to compress a mp3 back to a wav file and then to compress it with mo3 ?

Thanks

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.  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.  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.  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.  That is the nature of lossy compression.

First, to clear up the vocabulary a little.  Converting an MP3-encoded file back to the Wave format is called decompressing or decoding.  Secondly, MO3s are not simply compressed Waves.  MO3s are music modules in which the samples have been encoded using MP3, OGG, or lossless compression.  MO3 is not a stream compression, like MP3 and OGG.

No, Bass cannot.  If you want the de-/encoders, go to http://lame.sourceforge.net/ and http://www.vorbis.com/ for LAME (MP3) and the Vorbis info (OGG) respectively.

Actually, BASS can decode MP3 and OGG :)

maybe there will be also encoding in the next version ;D

I'm not certain, but I think MP3 encoding will be unlikely because you have to pay a licence to enode above a certain bitrate (I think).
