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.
