=head1 NAME

Nama - digital audio workstation

=head DESCRIPTION

B<Nama> is a lightweight digital audio workstation
using Kai Vehmanen's Ecasound as the audio engine.

New projects begin with a mixer, can include track, bus,
effect, send, insert, mark, region and fade objects.
Facilities are provides for mixdown, and mastering.

=head2 Command language and help system

Nama has its own command language.  Commands have full names
and shortcuts. A "for" loop allows commands to be repeated
over multiple tracks, which can be designated as a list, by
the name of their bus, or by the name of a user-defined
group. Nama has the concept of a currently selected object.
At any time, there is usually a current bus, current track
and current effect. Track commands will act on the current
track, bus commands will act on the currently selected bus.
The help system provides searchable access to documentation
for all Nama commands and shortcuts, and for LADSPA, LV2 and
Ecasound effects.

=head2 Backend

Nama creates signal processing graphs for the Ecasound
engine; applies fades, effects and edits to the audio
streams; and manages successive configure-run cycles.  If
jackd is running, Nama will automatically map soundcard IO
via JACK. 

When a user command causes a major configuration change,
Nama reconfigure the Ecasound engine then manages the
engine's realtime operation. While the engine is running it
allows live effect controller inputs from MIDI devices, GUI
effect sliders, and text commands, as well as preprogrammed
envelopes.

=head2 User environment

In addition to executing its own commands, Nama will pass
commands to Ecasound, Midish, the Perl interpreter or the
shell. 

Nama's optional Tk-based GUI can coexist with the
terminal. It does not display a waveform, however Nama can
spawn an Audacity or MHWaveedit instance to view/edit a
waveform. Nama uses Git to manage project state, which is
serialized as JSON files.


=head2 Project reuse

Three types of templates are available to reuse project
components: effect chains, effect profiles, and project
templates. Applying an effect profile creates named tracks,
each with a list of effects and inserts.  (Nama's mastering
network is stored as an effect profile.) 

=head1 INSTALLATION

=head2 Installing Nama and its Perl Dependencies from CPAN

The following command will install Nama, automatically
pulling in all Perl modules required to run Nama in text mode:

		cpanm Audio::Nama

However if you don't have cpanm, this should still work:

		PERL_MM_USE_DEFAULT=1 cpan Audio::Nama

To use the GUI, you will need to install Tk:

		cpanm Tk

You may optionally install Audio::Ecasound to run Ecasound
via libecasoundc:

		cpanm Audio::Ecasound

You can browse the sources or download a tarball via:

		http://search.cpan.org/dist/Audio-Nama

=head2 Installing Nama from your distribution's package manager

=head3 Debian (testing, unstable) 

You can install Nama from Debian by typing:

		apt-get install nama

or

		aptitude nama

To use Nama's GUI, you will also need to install Tk:

		apt-get install perl-tk

=head3 Ubuntu (lucid, maverick)

Use Ubuntu's package Add/Remove tool.

=head3 Arch Linux
	
=head2 Build from Source

If you want to inspect or modify Nama's internals,
you can pull the source code as follows: 

		git clone git://github.com/bolangi/nama.git

Consult the F<BUILD> file for build instructions.

=head2 Non-Perl Dependencies

(These dependencies are pulled in automatically if you
install Nama in a Debian system.)

The Ecasound audio processing libraries should be installed.
Ecasound should be compiled with support for LADSPA, libsndfile,
libsamplerate and JACK. Ecasound may be obtained from
http://ecasound.seul.org/ecasound/ or as precompiled binary
package for your Un*x distribution.

The LADSPA SDK is required to autosense LADSPA plugins and
scaling hints.  It is available at:

http://www.ladspa.org/ladspa_sdk/download.html  

In particular the utility program 'analyseplugin' must be
installed in a directory in your execution PATH.  

Nama's mastering mode uses a number of LADSPA plugins
in a reasonably flat starting configuration.
provided that the user installs the plugins
listed in the default configuration file .namarc.

Git is required to utilize Nama's source control 
and undo features.
