BitrateCompressionCalculator for Python
A simple Python utility to calculate file size from bitrate.
BitrateCompressionCalculator for Python (BCCpy) is a very simple application for calculating a file size from length and bitrate. BCCpy came about as the result of my beginning to learn Python and recreating the basic functionality of a simple VB program I wrote back in 1999. Since I was never very proficient with Visual Basic (or Applesoft BASIC for that matter); this application is very basic and could use lots of improvements. I'll implement them as I learn them. As of October 6, 2018; I have "abandoned" the project. I have actually forgotten everything I know about Python since writing this and other than adding error handlers; I really don't know how much further I could take it. I wanted to build a simple calculator, and I did. -
