I have now uploaded my "recaller" widget to the autobuilder, it built OK and should show up in extras-devel during the next hours (IF the servers work again - I have 0.2.0 of sleeper still not showing up in the package interface after 2 hours in the queue). The widget is encoding in AAC stereo right now at 128 kBit - this takes about 1 MB per minute in very good quality. Probably overkill, but the 27 GB in MyDcos give you 460h of recording time, so everything has become a bit relative on a monster like the N900 :-)
And yes, the widget can also be used as a simple recorder/dictaphone. Best regards -Tom > Just one thought on this: > > Most people are going to do playback on the device.
