Hi Lars,
Glad you've sorted out the basics of your audio system.
Suppose have a .wav recording of a classical concert you did on
your Zoom recorder, and want to break it up into individual
movements, processing each separately.
Probably the first thing to do would be to import the .wav file,
nama> create_project concert_foo
nama> add_track entire # becomes current track
nama> import_audio /some/path/to/a/wav/file.wav
Like many other Nama commands, import_audio relates to
the current track, which is "entire".
Nama will copy file.wav to $HOME/nama/concert_foo/.wav/entire.wav
(or possibly entire_1.wav) performing resampling if
necessary.
You can also do it from the shell (without resampling)
$ mv file.wav ~/nama/concert_foo/.wav/entire.wav
or
$ ln -s file.wav ~/nama/concert_foo/.wav/entire.wav
One way to work would be to deal with each movement as
one track.
First you would drop marks
(move playhead)
nama> mark first_movement_start
(move playhead)
nama> mark first_movement_end
nama> help new_region
Create a region for the current track using an auxiliary track
Parameters: <s_start_mark_name> <s_end_mark_name> [<s_region_name>]
nama> new_region first_movement_start first_movement_end first_movement
This creates a new track called "first_movement" that uses
the .wav file from "entire" but playing the portion
between the two marks.
While you work on first_movement,
you will have all other tracks set to OFF.
nama> entire mute
nama> first_movement
Add all the effects you want to first_movement
then, you can mixdown. Mixdown_1.wav will be
the result. You can rename that to first_movement.wav.
You can follow the same method for the other movements.
If you had a lot more complicated processing, you
might create a project for each movement. In that
case, use link_track command to tell Nama where
to get the audio.
Hope this helps,
Joel
