I managed to download the audio of 12 hours of white noise from into a mp3 file. The file is 661 MB. I wonder if it is possible to reduce its size without losing its sound quality noticeably?

My OS is Ubuntu 12.04. So I prefer software that works under it.

Do you know the current bitrate? The size of the file doesn't tell that it's 320kbps or just 128, it just says that it's large. – nerdwaller Nov 28 '12 at 22:54
@nerdwaller: how can I check that bitrate? I will do it once I finish downloading it. How is the bitrate help me reduce the file size? – Ethan Nov 28 '12 at 23:00
I think exiftool does it, try exiftool -AudioBitrate nameOfFile.mp3 this article from SuperUser agrees (and provides other options). – nerdwaller Nov 28 '12 at 23:04

What exactly would be a noticeable loss of quality for white noise? – terdon Nov 29 '12 at 13:19

Since it's white noise, why don't you just grab 10 seconds of it and loop that in your favourite media playing software?

+1 for being awesome. – nerdwaller Nov 28 '12 at 22:55

what about this site; this goes on forever. (assuming web connection and power are in place forever) and there's (presumably) no compression. and; gives instructions for a command line noise generator. (so you could control it, for sleeping etc.)
