Saving A Selection
Assuming it sounds good and it doesn't start going all muffled after 30 seconds because your Sound Recording turned all that crap off, then:
Left-click at the 'start' of the waveform.
Hold down SHIFT then left-click at the 'end' of the waveform.
Now left-click the 'File' menu and choose 'Save Selection...'.
This will remove and save just the Colour Genie waveform from the entire recording (and will make the final conversion faster!) You need to save it as a '.voc' file. The .voc format was a very popular file format in 1997 when the Colour Genie Conversion Tools were written and they expect .voc format files!
Important Note: Keep your filename shorter than eight characters (i.e. "Maths.voc" rather than "Maths_Magic.voc"). You'll have to use an old version of MS-DOS in the next part and MS-DOS was restricted to eight characters back in 1997 too.
Give your new waveform a name and, for sake of ease, create a new directory on your hard drive called 'tools' (C:\tools\). You'll see why this is easiest in a few moments. Click 'Save' to save it.
The first time you do this, you will get a warning box stating that you are saving to a 'lossy' format. Click 'Don't display this message in the future' then 'OK'.
You can then 'Close' (Ctrl-W) the original waveform as you no longer need it.
