Ken, A megabyte to a minute of play time generally is close for a 128 bit fixed rate encoded MP3. A 256 bit fixed rate would be double, etc. However, many files are encoded in Variable bit rate which is not quite as easy to predict. In Winamp you can use Alt+3 during playback to obtain information about the file including bit rates. --- HTH --- ----- Original Message ----- From: Kenlawrence124@xxxxxxx To: jfw@xxxxxxxxxxxxx Sent: Friday, July 23, 2010 1:57 PM Subject: bit rate and file size? Hi list members ken here with a question about the bit rate and running time of songs downloaded. Today I downloaded a runaways song from 4shared.com the file is the whole song but it only shows about 1.6 MB. I had heard somewhere that a meggabite is about a minute of running time listening to a song. How does the bit rate of a file impact the listening time? Also is there a way to find out the bit rate of a song using the Jaws cursor while listening to it? I know you can do it with a stream such as an Online radio station. Thanks ken.
