is it normal?

[Rudransh]

I exported around 5 minute long mix in .wav format with highest sample rate possible in cbB and it's size is around 500MB! , is it normal?  even I need to use .wav format?

Wav file size is easy to compute. The formula is

sampleRate X bitDepth X numberOfChannels X runtime = fileSize

 

Here is a decent web-based calculator

depends on the sample rate and bit depth.

File size is covered in the documentation http://www.cakewalk.com/Documentation?product=Cakewalk&language=3&help=AudioPerformance.16.html

But they don't both to document sample rates above 96kHz.
