Nama
Easy multitrack recording with Ecasound
Future developments
Most people will go to an application like Ardour for professional-level audio production needs, so Nama's development will be driven by user needs, and by any developer contributions.
Nama could potentially do a lot more. Here are some ideas I have floating around.
Latency compensation
MIDI integration
Time-based effects processing
Ecasound already has some envelope processing. It would be nice to add the ability to record (and playback) realtime changes in effect parameters sent by MIDI, GUI and command inputs.
Graphic waveform display
An interesting project, though a bit more than I personally want to take on at the moment. And not strictly necessary. After all, audio production is first and foremost about listening.
Better-looking GUI library
Learning about GTK or WxWidget would be fun. Recoding Nama's GUI will be a pretty big job, or perhaps a fun summer project.
