I managed to download the audio of 12 hours of white noise from http://www.youtube.com/watch?v=1KaOrSuWZeM 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
  • Use MediaInfo...mediainfo.sourceforge.net/en – Moab Nov 29 '12 at 3:55

    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?


what about this site; http://simplynoise.com/ this goes on forever. (assuming web connection and power are in place forever) and there's (presumably) no compression. and; http://dirk.net/2009/07/14/white-noise-generator-for-linux/ gives instructions for a command line noise generator. (so you could control it, for sleeping etc.)
