One Interesting Question

[Lakshmipathi]

Hi all,
Here an interesting question :

I'm having an mp3 file of size 4MB -is it possible to calculate the time duration
of this song?

My problem is I need to compute time duration for a vodcasting site

Any idea

You would have to know the bitrate at which the track was encoded. A higher bitrate will mean a larger file, even if the track itself is short. For instance (these are just guesses; I don't know the exact conversion):

Standard 3 minute song at 128kb : approximately 4MB
Standard 3 minute song at 256kb: approximately 8MB

Short 30 second track encoded at 495kb : approximately 4MB

It all depends on the bitrate.

Thanks techieMoe
Do you have any docs or links regarding how the conversion works ?
I tried google but not getting any useful links
