Interesting issue with MP3 encoder in Sonar

Okay I am creating separate mp3 parts for backing tracks (I use Cantabile live so can actually play multiple MP3s at the same time)..
So here's the thing...each part created as an MP3 is exactly the same size?? Some tracks only have about 6 bars of audio total...How can this then equate to an 8mb mp3 file for this single part? And indeed each other part is also an 8mb file size..
 
Any ideas?

This helps to line up tracks actually. 
 
Still, turning on VBR should create smaller files for those that have a lot of silence in them.

Yeah but VBR has inherent issues in Sonar - like leaving a file that is like, 23 minutes long when it is really only 4 haha!

yeah, running Lexington at present...however that reply scook, does not really address the OP hahaha!
There must be a better way to only save the actual data from a track with creating these humungous tracks - or is it an inherent isse with the mp3 codec?

It was not in reply to the OP was it.
 
The OP does not provide much information. There is a difference between exporting a track and exporting a clip. If that the issue see http://forum.cakewalk.com/FindPost/3146261
 

hahaha! I AM the op .. thanks for the link interesting read..so it seems my assumption is correct, if I don't export the track, the component parts will end up all at 0 start point. I have experimented in Audacity to remove the time between audio content in the MP3 and it does reduce the size somewhat, but with, sometimes, up to 8 tracks to do per song this will get very passe very quickly hahaha!  So it's either be stuck with huge mp3 files or give up the idea altogether.
 
Maybe just run sonar live via playlist , but that has issues as it doesn't close down CWP's when a new one is loaded...I can see issues with that once there are about 20-30 CWP's sitting in the background!
 
Oh well, back to the drawing board..
 
Thanks

on the contrary Scook - but there seems to be NO solution...I cannot export a track that only has say 4 bars of audio data to anything less than the size of the biggest track. That seems to be the upshot, so yes, not solution possible in regard to the OP.
 
Sorry to see you taking that attitude! It is not like you.

Thanks John, yes that was the solution I came up with - as I wrote earlier - in fact I can do this with an MP3 of the data as well as wav (using Audacity) and it does reduce the sized somewhat, however it is not ideal and is labour intensive when dealing with multiple parts to edit. But it is a solution haha!
 
And yes I totally agree, it is the desired behaviour it was a method of running live dynamically mixable MP3 parts that got me along this path - it is the one thing I miss about MIDI, that ability for live control.
 
I am also looking at using Sonar itself as the live tool, however I have not come across any way to remove projects after they are finished, using the Playlist option. As I wrote earlier, when one has say 30-40 CWP's stacked in the background, then I can see possible issues coming from that.
 
Still there may even be a work-around for that too Unfortunately Scook did not comprehend my posts, and simply took the view I was not looking for a solution...I did try to keep it light, hence the laughs etc...he must have been having a bad day hahaha!
 
Thanks for your post!
