Can anybody please show me how to calculate the filesize of a given audio file's data?
In proper maths...
For Example:
Windows Media Audio 9
128 kbps, 44 kHz, stereo 1-pass CBR
Length: 04:29 (269 seconds)
How can we determine the file size mathemtically? I have got only slight idea on how. I know the know the maths to do it
but not how to use the kHz data for it.
So what I did was:
128kb/s * 269s = 34432kb
34432kb / 8b = 4304kB
4304kB / 1024 = 4.203125 MB =
4.2MB
But the actual file size is
4.14MB
Is that right? But I didn't use the fact 44.1kHz
Will that affect the file size? Please help..
