If a file is mono, it has 1 channel only. Sure, you could convert it to a stereo audio file, but it would sound the same and you'd simply be inflating the file size.
There are effects which can add a pseudo-stereo field to mono audio, but in the end you'll still have one channel stretched across the stereo spectrum, rather than true 2-channel sound. -- James Scholes http://twitter.com/JamesScholes To unsubscribe from this list, send a blank email to: pc-audio-unsubscr...@pc-audio.org
