Comparative file sizes wav & mp3

[isabel95]

I'm puzzled.

If I record a music track from an audio cd and convert it to mp3 using CDex, the mp3 file is much smaller, yet last night I made a short recording with my digital camera of cicadas and when I converted the wav file to mp3 the resulting file was about 100kb larger than the original wav file.

Can anyone explain why?

Isabel

think you are going to have to supply more information for anybody to give you more help

file sizes

compression

bit rate of both tunes

are just a few things that you are going to have to supply

in the interim see

you will see what we take for granted is really not that simple - there is a whole lot of things going in the background:)

Bonjour Isabel,

I used 4 years ago a tool which made Wave file with compression, and I succeeded to open these files with other tools which where unable to read other format as Wav. I haven't to day this tool because it doesn't do better than ogg or mp3 and is not really a standard file. I just keep a wav file that I used in one of my shows. It is 2908 Kb for 7' 05" length (compression rate = 12/1).

Probably your camera use such a file

NB I you want I can send you the wave file.
