The audio library irrKlang
is out now in version 0.9.1, including some new features and - as announced
- there is a license change making it free for non-commercial use. Here is the background:
In the beginning of this month, a new version of irrKlang was released but some of the new features were only available when purchasing a license. This license model has been chosen because irrKlang was originally intended to be free, also for commercial use. Unfortunately, a lot of users - especially people with an Irrlicht background - are using irrKlang in free or open source 3D projects and need those features which were only available in the commercial version of irrKlang, and began to send mails to me, asking for a license change. I recieved a huge amount of mails like this and because it made sense, the license has been changed now
: irrKlang can now be used with all those features completely free for non-commercial use. If you are using irrKlang in a commercial product and making money with it anyway, you have to pay a small license fee.
I think that license model is more fair and widely accepted, a lot of other programming libraries are doing it this way. I hope everybody is ok with this now, happy programming. :)
Assuming there's no startlingly innovative algorithms that you don't want to reveal it might be worth considering what the practical difference for you actually is between GPL'ing and this.
