I recorded this little song with Ardour, mixed it using LADSPA plugins and mastered it with Jamin. Overall it was a great experience and I learned a lot. I used exclusively Free Software and I'm somewhat proud of it ;)
Check it out!
Italians (if there are any) can check the lyrics and additional info here
After this positive experience, I'm going to record more complex songs in the future.
Thanks to Ardour devs for such a great tool!
