Is there any difference in Audacity, Reaper, WavePad?
Last I checked, Audacity was a 2-track editor for single stereo files (2 tracks in one stereo file)...along the same lines as Wavelab and SoundForge.
Reaper is a multi-track DAW environment. There's no rule saying you can't use a multi-track application for 2-track editing - it's just generally accepted that 2-track editors allow one to do that job more efficiently - they have tools, hotkeys, etc. laid out for quick editing of
one file.
What do the high end products (I don't know what they are for editing Wav. files really, Pro-tools, Cubase? ) offer that these don't for this kind of situation?
Zuul
Pro-tools and Cubase are "high end" multi-track DAW products (although many reputable users of Reaper report consistently that it is not inferior in any way to these much-more-expensive products...). Again, this is not really what you need right now.
The "high end" 2-track editors were Wavelab and SoundForge the last time I looked into them - they offer the same basic functionality as Audacity. The main difference is the support system, which you can call 24 hours a day, whereas with Audacity you get help from the user community on the forums, mailing lists... things like that. To a casual user/hobbyist, this is fine. You can generally get excellent help on forums and mailing lists, but you may have to wait a few hours, days or even weeks on rare occasions. People who rely on this software to pay their bills sometimes feel that a 24 hour support line is worth shelling out money for.
If you want to know the difference beyond that basic info, download the demo versions of Wavelab and Soundforge and check them out side-by-side with Audacity for yourself... A lot of people feel the "High End" software is better laid out, easier to use, easier on the eyes, and an endless list of other subjective opinions. As far as I know, they are not superior in any objective, technical way. Believe it or not, well-established open-source projects (like Audacity) are very often of extremely high-quality - often performing even better than their proprietary counterparts in benchmark tests. They're also often perceived as ugly/plain, hard to use, and non-professional (although professional results can be attained, this is just the perception I have seen over and over again...)
