I came across an announcement about an audio editor called “Ocenaudio” available for free which is cross-platform. It sounded good. I looked at the web site and found out that they don’t mention a license. Most open-source/Free Software programs are proud of their use of the GPL or any of the other open licenses.
Ocenaudio does not have an open license according to this forum post.
Just because it is “free” as in gratis, no required payment does not qualify it as Free Software (also often called “open source”). With “Free” as in libre, the issue isn’t cost at all, but your liberty/freedom use without limits, to study it, to adapt the work to your needs and to redistribute your version as long as you don’t try to limit others from those same four freedoms.
For somebody just looking for cheap, I guess there’s no difference. But for those who care to build a strong, community supported software commons, Libre matters way more than Gratis.
I’ll keep recommending Audacity instead of ocenaudio, too.
