NAME
Nama - multitrack recorder and digital audio workstation
SYNOPSIS
nama [options] [project-name]
DESCRIPTION
A multitrack audio application for recording, effects processing, editing, mixing,
mastering and live performance. It can also perform general-purpose audio processing, such
as 5.1 to stereo conversion. Nama uses Ecasound as the audio processing engine.
Audio projects
Projects in Nama are audio networks of tracks and buses. Tracks may contain one or more
RIFF (.wav) files, as well as effects, sends, inserts, marks, regions, fades, edits and
sequences. Tracks can host LADSPA, LV2 and Ecasound plugins. Audio regions may be
altered, duplicated, time-shifted or replaced.
Audio processing is performed in realtime when a track is played and may be cached
(frozen) to a new audio file.
Project data is serialized as JSON. The complete history is tracked by the git version
control system. As a result, projects can be managed using branches and tags, and provide
undo/redo.
Nama supports some MIDI functionality via midish.
Presets and templates
To facilitate reuse, a track's plugins and inserts can be stored as an effect chain.
Effect profiles apply effect chains to groups of tracks. Project templates are for
duplicating an entire project sans audio files.
Audio device
Nama performs Audio IO via JACK or ALSA. Soundcard IO goes via JACK, if running, with
transparent fallback to ALSA.
Nama supports Ladish Level 1 session handling.
User interfaces
Nama has fully featured terminal command prompt, a Tk GUI, and experimental OSC and
remote-command modes.
The command prompt can run Nama commands, Ecasound interactive-mode commands, commands for
the midish MIDI recorder/player, shell commands and perl code. Commands and filenames can
be autocompleted using the TAB key. Command history is available to browse with up and
down arrows.
The help system provides documentation and keyword search covering Nama commands and
effects-processing plugins.
The hotkey mode provides a convenient way to select, view, and modify effect parameters.

CONTROLLING NAMA/ECASOUND
The Ecasound audio engine is configured through use of chain setups that define the signal
processing network.
Nama serves as an intermediary, taking high-level user commands, generating chain setups
for user tasks such as recording, playback, mixing, etc., and running the audio engine.
Configuration Commands
Configuration commands affect future runs of the audio engine. For example, rec, play,
mon and off determine whether the current track will get its audio stream from an external
(e.g. live) source, whether an existing audio file will be played back, and whether a new
audio file will be recorded. Nama responds to these commands by reconfiguring the engine
and displaying the updated track status. See 'man ::ChainSetup' for details on how the
chain setup created.
Realtime Commands
Once a chain setup is loaded and the engine is launched, commands can be issued to control
the realtime behavior of the audio processing engine. These commands include transport
"start" and "stop", playback head repositioning commands such "forward", "rewind" and
"setpos". Effects may be added, modified or removed while the engine is running.
Configuration
General configuration of sound devices and program options is performed by editing the
.namarc file, which is formatted as YAML. On Nama's first run, a default version of
.namarc is placed in the user's home directory.
Tk GRAPHICAL UI
Invoked by default if Tk is installed, this interface provides a subset of Nama's
functionality on two windows:
Main Window
The top section has buttons for creating, loading and saving projects, adding tracks,
adding effects to tracks. In short, for setup.
Below are buttons for controlling the transport (start, stop and friends) and for setting
marks.
The GUI project name bar and time display change color to indicate whether the upcoming
operation will include live recording (red), mixdown (yellow) or playback (green).
Effects Window
The effects window provides sliders for each effect parameter of each track. Parameter
range, defaults, and log/linear scaling hints are automatically detected. Text-entry
widgets are used to enter parameters values for plugins without hinted ranges. Any
parameter label can be clicked to add a parameter controller.
Waveform Window
Provides a conventional view with waveform and playback head.
Terminal Window
The command prompt is available the terminal window and provides access to all of Nama's
functions.
TEXT USER INTERFACE
Press the Enter key if necessary to get the command prompt, which will look something like
this:
"nama untitled sax ('h' for help)>"
In this instance, 'sax' is the current track in the 'untitled' default project.
When using buses, the bus is indicated before the track:
"nama untitled Strings/violin ('h' for help)>"
At the prompt, you can enter Nama and Ecasound commands, Perl code preceded by "eval" or
shell code preceded by "!".
Multiple commands on a single line are allowed if delimited by semicolons. Usually the
lines are split on semicolons and the parts are executed sequentially, however if the line
begins with "eval" or "!" the entire line (up to double semicolons ';;' if present) will
be given to the corresponding interpreter.
You can access command history using up-arrow/down-arrow.
Type "help" for general help, "help command" for help with "command", "help foo" for help
with commands containing the string "foo". "help-effect foo bar" lists all
plugins/presets/controller containing both foo and bar. Tab-completion is provided for
Nama commands, Ecasound-iam commands, plugin/preset/controller names, and project names.
Most commands have abbreviations, such as 'afx' for 'add-effect'. These are shown in the
help listings.
TRACKS
Each track has a descriptive name (i.e. vocal) and an integer track-number assigned when
the track is created. New user tracks initially belong to the Main bus.
Track output signals are usually mixed and pass through the Main track on the way to
soundcard for monitoring.
The following sections describes track attributes and their effects.
Width
Specifying 'mono' means the track has one input channel, which will be recorded as a mono
WAV file. Mono track signals are automatically duplicated to stereo and a pan effect is
provided.
Specifying 'stereo' for a track means that two channels of audio input will be recorded as
an interleaved stereo WAV file. You can also use a 'stereo' declaration to avoid the
automatic channel copy usually applied to single-channel sources.
Specifying N channels for a track ('set width N') means N successive input channels will
be recorded as an N-channel interleaved WAV file.
REC/PLAY/MON/OFF
Basic signal routing for each track is controlled by its setting to REC, MON, PLAY or OFF.
The MON setting prepares to connect the live track source.
The REC setting prepares to connect the live track source and record it to an audio file.
The PLAY setting enqueues an audio file for playback from disk as the track source.
The OFF setting tells Nama to remove the track from the audio network. OFF status may
result for a track when no audio source is available. For example, a track with no
recorded audio files will show OFF status when set to PLAY.
Track output
By default a track belongs to the Main bus and is routed to the Main track. This track
provides a final fader before the signal goes via ALSA or JACK to the audio device.
Bus setting
Buses can force the status of their member tracks to OFF. Nama provides MON and OFF
settings for buses. OFF (set by "bus-off") removes all member tracks from the chain
setup, MON (set by "bus-mon" restores them.
The mixplay command sets the Mixdown track to PLAY and the Main bus to OFF.
Version Numbers
Multiple audio files ("takes") can be recorded for each track. These are distinguished by
a version number that increments with each recording run, i.e. sax_1.wav, sax_2.wav, etc.
All audio files recorded in the same run have the same version number.
The version numbers for track playback can be selected at the bus or track level. By
setting the bus version to 5, you can play back version 5 of several tracks at once.
Version 5 could signify the fifth take of a song, or the fifth song of a live recording
session.
The track version setting, if present, overrides the bus version setting. Setting the
track version to zero restores control of the version number to the bus.
The Main bus version setting does not propagate to other buses.
Marks
Marks in Nama are similar to those in other audio editing software. One limitation is that
mark positions are relative to the beginning of an Ecasound chain setup. If your project
involves a single track, and you will be shortening the stream by setting a region to
play, set any marks you need after defining the region.
Regions
The "region" command allows you to define endpoints for a portion of an audio file. You
can then use the "shift" command to move the region to the desired time position.
If you use named marks as endpoints, the region will change if the mark's position is
adjusted.
Each track can have one region definition. To create multiple regions, the "new-region"
command takes a pair of marks to create a read-only copy of the current track with the
specified region definition.
You can control this region as you would any other other track, shifting the start time,
applying effects, adjusting volume, etc.
Using Tracks from Other Projects
The "link-track" clones a read-only track from another track, which may belong to a
different project.
Effects
Each track gets volume and pan effects by default. New effects added using "add-effect"
are applied before pan volume controls. You can position effects anywhere you choose
using "insert_effect" or "position-effect".
Fades
Fades can be placed on any track. They defined by mark position and duration. An
additional volume operator, -eadb, is applied to each track to host the envelope
controller that implements fades.
Sends and Inserts
The "send" command can route a track's post-fader output to a soundcard channel or JACK
client in addition to the normal mixer input. Nama currently allows one aux send per
track.
The "add-insert" command configures a pre- or post-fader send-and-return to soundcard
channels or JACK clients. Wet and dry signal paths are provided, with a default setting
of 100% wet.
Each track can have one pre-fader and one post-fader insert.
Bunches
A bunch is just a list of track names. Using the "for" keyword with the name of a bunch
will apply the commands that follow to all of the tracks in the bunch. A bunch can be
created with the "new-bunch" command. A bus name can also be treated as a bunch.
Buses
Buses enable multiple tracks to be routed through a single mix track before feeding the
Main mixer bus (or possibly, another bus.)
The following commands create a bus and assign three tracks to it. The mix track takes the
name of the bus and is stereo by default.
# create a bus named Strings with a same-named mix track
add-bus Strings
# create tracks for the bus
add-tracks violin cello bass
# move the tracks from the Main bus (default) to the Strings bus
for violin cello bass; move-to-bus Strings
# use the mix track to control bus output volume
Strings vol - 10
Submixes
Submixes are a type of bus used to provide instrument monitors, or to send the outputs
from multiple user tracks to an external program such as jconverter.
ROUTING
General Notes
While Nama can address tracks by either name and track number, Ecasound chain setups use
the track number exclusively.
The Main track (mixer output) is always chain 1, the Mixdown track is always chain 2.
Nama uses Ecasound loop devices where necessary to connect two tracks, or to allow one
track to have multiple inputs or outputs. Each loop device adds one buffer, which
increases latency.
Flow Diagrams
Let's examine the signal flow from track 3, the first available user track. Assume track 3
is named "sax".
We will divide the signal flow into track and mixer sections. Parentheses show the chain
id.
The stereo outputs of each user track terminate at Main_in, a loop device at the mixer
input.
Track, REC status
Sound device --+---(3)----> Main_in
/JACK client |
+---(R3)---> sax_1.wav
REC status indicates that the source of the signal is the soundcard or JACK client. The
input signal will be written directly to a file except in the special preview and doodle
modes.
Track, PLAY status
sax_1.wav ------(3)----> Main_in
Mixer, with mixdown enabled
In the second part of the flow graph, the mixed signal is delivered to an output device
through the Main chain, which can host effects. Usually the Main track provides final
control before audio output or mixdown.
Main_in --(1)--> Main_out --+--------> Sound device
|
+-->(2)--> Mixdown_1.wav
Mastering Mode
In mastering mode (invoked by "master-on" and released "master-off") the following network
receives the Main track signal as input and provides an output to the soundcard or WAV
file.
+- Low -+
| |
Main_in --- Eq --+- Mid -+--- Boost -> soundcard/wav_out
| |
+- High +
The Eq track hosts an equalizer.
The Low, Mid and High tracks each apply a bandpass filter, a compressor and a spatialiser.
The Boost track applies gain and a limiter.
These effects and their default parameters are defined in the configuration file .namarc.
Mixdown
The "mixdown" command configures Nama for mixdown. The Mixdown track is set to REC
(equivalent to "Mixdown rec") and the audio monitoring output is turned off (equivalent to
"Main off").
Mixdown proceeds after you start the transport.
As a convenience, Mixdown_nn.wav will be symlinked to <project-name_nn.wav> or
<branch_name_nn.wav> in the project directory. The latter format is used branches other
than the default master branch.) Corresponding encoded files are created if the
mixdown_encodings option is set in .namarc. Acceptable values are a space-separated list.
The default is "mixdown_encodings: ogg mp3".
Preview, Doodle and Eager Modes
These non-recording modes, invoked by "preview" and "doodle" commands tweak the routing
rules for special purposes. Preview mode disables recording of WAV files to disk. Doodle
mode disables PLAY inputs while excluding any tracks with the same source as a currently
routed track. The "arm" command releases both preview and doodle modes.
The eager setting causes the engine to start immediately following a reconfiguration.
Saving Projects
If git is available, projects are saved automatically after each command and it is not
necessary to explicitly save your work.
When you type "save", Settings related to the state of the project are saved in the file
State.json in the project directory. State.json is tracked by git.
"save" updates several other data files as well:
Aux.json, also in the project directory, contains data that is part of the project (such
as command history, track comments, and current operating modes) but with no direct effect
on the project audio.
global_effect_chains.json, in the project root directory (usually ~/nama) contains system
and user defined effect chains.
Save without Git
"save somename.json" will save project state to a file of that name. Similarly "get
somename.json" will load the corresponding file. The .json suffix may be omitted if
"use_git: 0" is set in .namarc.
Save with Git
If git is available, Nama uses it to store snapshots of every step in the history of your
project.
When you type "save initial-mix", the latest snapshot is tagged with the name "initial-
mix", which you can recall later with the command "get initial-mix".
You can include a comment with the snapshot:
"save initial-mix "sounds good enough to send to the front office""
Nama lets you create new branches, starting at any snapshot.
To start a new branch called compressed-mix starting at a snapshot called initial-mix you
would say:
"new-branch compressed-mix initial-mix"
If you want to go back to working on the master branch, use "branch master".
You can also issue native git commands at the Nama prompt.
Git history example
All projects begin on the "master" branch. Because this is the default branch, it is not
displayed in the prompt. Otherwise "master" is not special in any way.
In the graphs below, the letters indicate named snapshots.
create test-project
...
save a
...
save b
...
save c
---a---b---c (master)
get a
...
save d
...
save e
...
save f
d---e---f (a-branch)
/
-----a----b---c (master)
Now, you want to go back to try something different at "c":
get c
...
save g
d---e---f (a-branch)
/
----a----b---c (master)
\
g (c-branch CURRENT HEAD)
You could also go back to master, and restart from there:
get master
...
save h
...
save i
d---e---f (a-branch)
/
----a----b---c---h---i (master CURRENT HEAD)
\
g (c-branch)
Merging of branches is not supported.
Exiting
When you type "quit" Nama will automatically save your work to State.json. If you don't
want this behavior, use Ctrl-C to exit Nama.
Jack ports list file
Use source filename.ports to ask Nama to connect multiple JACK ports listed in a file
filename.ports to the input port(s) of that track.
If the track is stereo, ports from the list are alternately connected to left and right
channels.
Track edits
An edit consists of audio clips and data structures associated with a particular track and
version. The edit replaces part of the original audio file, allowing you to fix wrong
notes, or substitute one phrase for another. Behind the scenes, the host track becomes
the mix track to a bus. Sources for the bus are the original audio track, and zero or more
edits, each represented by a hidden track.
Each track can host multiple edits. Edits are non-destructive; they are achieved by using
Ecasound's ability to crossfade and sequence.
Before creating the edit, select the track and version to be edited. You will now need to
create three marks:
• play start point =item * rec start point =item * rec end point
The edit will replace the audio between the rec start and rec end points.
There are two ways to set these points.
set-edit-points command
Position the playback head a few seconds before the edit. Enter the set-edit-points
command. This will start the engine. Hit the P key three times to designate the playback
start, punch-in and punch-out positions.
Specify points individually
Position the playback head at the position you want playback for the edit to start. Enter
the set-play-start-mark command.
Use the same procedure to set the rec start and rec end positions using the set-rec-start-
mark and set-rec-end-mark commands.
Create the edit
Enter the new-edit command to create the necessary tracks and data structures.
Use preview-edit to confirm the edit positions. The engine will run and you will hear the
host track with the target region removed. Playback will be restricted to the edit region.
You may use preview_out to hear the clip to be removed.
Use list-marks to see the edit marks and modify-mark to nudge them into perfect position.
Once you are satisfied with the mark positions, you are ready to record your edit.
Enter start-edit. Playback will begin at first mark. The replacement clip will be recorded
from the source specified in the original track.
Each start-edit command will record an additional version on the edit track. redo-edit
will delete (destructively) the most recent audio clip and begin recording anew.
destroy-edit deletes (destructively) the current edit.
You may specify another range for editing and use the editing procedure again as many
times as you like. Edits on one track may not overlap.
Merging edits
merge-edits will recursively merge all edits applied to the current track and version,
creating a new version for the track. This will freeze your edits against an accidental
change in mark, region or version settings.
list-edits will label the edits by index and time.
end-edit-mode will restore normal playback mode
REMOTE CONTROL
You can send commands to Nama from a remote process, and retrieve the result. Understand
that this code opens a remote execution hole.
In .namarc you need something like:
remote_control_port: 57000
Then Nama will set up a listener for remote commands.
The usual return value will be a single newline.
However, if you send an 'eval' command followed by perl code, the return value will be the
result of the perl code executed with a newline appended. If the result is a list, the
items will be joined by spaces into a single string.
For example, if you send this string:
eval $this_track->name
The return value will be the name of the current track.
If the result is an object or data structure, it will be returned in a serialized form.

REALTIME OPERATION
Nama selects realtime or nonrealtime parameters based on the realtime_profile,
ecasound_buffersize and ecasound_globals fields in .namarc. You can optionally specify the
buffersizes as a multiple of the JACK period size. Note that for best realtime operation
under JACK you will have to configure jackd appropriately as well.
The realtime and auto profiles are useful when using Nama/Ecasound for live fx processing
or live monitoring.
The realtime profile sets a small buffersize and other low latency settings whenever a
soundcard or JACK client is connected.
The nonrealtime profile uses a bigger buffer, providing extended margins for stable
operation. It is suitable for post-processing, or for recording without live monitoring
responsibilities.
The auto profile defaults to nonrealtime settings. It switches to realtime, low-latency
settings when a track has a live input.
DIAGNOSTICS
On any change in setup, the GUI display updates and "show-tracks" command is executed
automatically showing what to expect the next time the engine is started.
You can use the "chains" command to verify the Ecasound chain setup. (The Ecasound command
"cs-save-as mysetup.ecs" will additionally store all engine data, effects as well as
routing.)
The "dump" command displays data for the current track. The "dumpall" command shows all
state that would be saved.
This is the same output that is written to the State.yml file when you issue the "save"
command.
BUGS AND LIMITATIONS
No latency compensation across signal paths is provided at present. This feature is under
development.
SECURITY CONCERNS
If you are using Nama with the NetECI interface (i.e. if Audio::Ecasound is not installed)
you should block TCP port 2868 if your computer is exposed to the Internet.
INSTALLATION
The following commands, available on Unixlike systems with Perl installed, will pull in
Nama and other Perl libraries required for text mode operation:
"cpanm Audio::Nama" -or- "PERL_MM_USE_DEFAULT=1 cpan Audio::Nama"
To use the GUI, you will need to install Tk:
"cpanm Tk"
You may want to install Audio::Ecasound if you prefer not to run Ecasound in server mode:
"cpanm Audio::Ecasound"
You can pull the source code as follows:
"git clone git://github.com/bolangi/nama.git"
Consult the BUILD file for build instructions.
SUPPORT
The Nama mailing list is a suitable forum for questions regarding Nama installation,
usage, bugs, feature requests, etc.
