I just started working with FMOD in VC++ and I was using the FSOUND_SAMPLE to stream from memory, I noticed it was taking up about 46mb to play a mp3 file. Is this average or did I do something incorrect?
edit : This is a song that is about 6mb in size.

It looks quite ok to me.
As a rule of thumb, I consider the disk space of the mp3 and I multiply by 10x or 12x. This is not really accurate but in my experience, it is the average MP3 compression ratio.
So, if your file takes 4-5MB on disk and it grows up to 46MB on memory, [b:3a0hxveh]I guess it’s right.[/b:3a0hxveh]
Now your file takes 6MB on disk… well, maybe the compression ratio is not the best I ever seen but it looks quite reasonable to me.
Think at the following:
CD audio = 80min of music
CD full of mp3 = DAYS of music

Not to nitpick, but a 700MB CD only holds around 160-200 MP3s… about 10-12 hours of music. A DVD, however (4.7GB) [b:3swhnbwt]would[/b:3swhnbwt] hold “days of music.” I actually have a full DVD’s worth of MP3s on my harddrive, btw… over 86 hours of music.

Well, of curse the bitrate decides (I have lots of old mp3 with very low bitrate around), however 6 hours a day it actually make two days.
However, this is not really important. For me, it actually takes some days to listen a whole MP3 CD. If you are able to do it in a single day… woah.
