mp3 compression (lossless)

jvonsteenburg

i have the new sirius S-50 portable w/50 hrs. storage, the problem is i can only use 512 mgs for personal storage. how can i compress my mp3 files w/out losing quality? anyone?

With Mp3 you don't have the option of lossless because the format was designed to reproduce lossy audio. Currently Flac, APE and WMA have lossless codecs however Mp3 does and never be lossless. Those formats won't play on a Sirius, though.

If you still wish to use Mp3, the closest you can get to lossless is "Alt Preset Insane" which is 320 kbps with a 44,000 KhZ sampling rate. This option will usually produce pretty good quality audio however each standard three minute track you rip or encode will be 10 Megabytes and there would be no way in hell of you getting all 50 hours of the advertised hours if you encode music in this way.

The simple fact of the matter is that if you want to listen to music on a portable player through headphones, it would be highly likely that you wouldn't be able to tell the difference between lossless audio or not. Encoding to 320 kbps Mp3 (or even lossless if it existed for Mp3) in that case is just a poor economy.

I would seriously recommend, for your case, using somewhere in the field of 96-192 kbps Mp3 encoding or VBR with those values.

Ok, well, if you're ripping from CD's you should use Express Rip, it has a very similar interface to Switch and is just as easy to use, you can download it from here.

Or use Switch to convert from a previously ripped file Mp3 and while using one of the afforementioned applications to make the Mp3 Encoder settings look like this:

Then click "Ok" and you're all good to start ripping or encoding.

As for your car dock, I can't really say how good the quality would be through there, however I guarantee with the settings above won't sound terrible. If you like, you can always try experimenting with higher bitrates or levels of encoding to Mp3 that work best for you, apart from that, I can't really advise you with that, sorry.

Any more questions feel free to post back here again.
