1 - Install Audacity and have a look to
the user guide for some basic tasks.
2 - Open the individual tracks previously
recorded and apply some filters as fade in,
fade out, normalizing, reverb, and cut the
long silences. Repeat for every track.
3 - Export the track as an mp3 and share it
with the group by dropbox. Repeat for
every track. If it is ok go to next step.
4 - Post the resulting shared folder with
the mp3 files in Twinspace.
