Nama - digital audio workstation
nama [options] [project_name]
Nama performs multitrack recording, effects processing, editing, mixing, mastering, live performance and general-purpose audio processing, using the Ecasound realtime audio engine. Audio Functionality Audio projects may be developed using tracks, buses, effects, sends, inserts, marks, regions, fades, sequences and edits. Each track may contain one or more WAV files, which may be recorded or imported. Effects processing by LADSPA, LV2 and Ecasound plugins may be performed in realtime, or cached (e.g. frozen) to a file. The user may toggle between cached and dynamic processing for a track. Audio regions may be altered, duplicated, time-shifted or replaced. Nama supports 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 and project templates provide templating for groups of tracks and entire projects, respectively. Audio framework Audio IO is via JACK or ALSA. Soundcard IO is normally routed to JACK with transparent fallback to ALSA. Persistence Project data parameters related to audio configuration are serialized as JSON and tracked using Git when available. The entire project history is retained and may be managed using branches and tags. 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 accepts Nama commands, Ecasound interactive-mode commands, shell commands and perl code. It has command history and autocompletion. The help system provides documentation and keyword search covering Nama commands and effects. The hotkey mode provides a convenient way to select, view, and modify effect parameters. By default, Nama displays a graphic user interface while the command processor runs in a terminal window.

The Ecasound audio engine is configured through use of chain setups that specify the signal processing network. Nama serves as an intermediary, taking high-level commands from the user, generating appropriate 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 WAV file will be played back, and whether a new WAV 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 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. On Nama's first run, a default version of .namarc is usually 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. Terminal Window The command prompt is available in the terminal window during GUI operation. Text commands are used to access Nama's more advanced functions.
TEXT USER INTERFACE
Press the Enter key if necessary to get the command prompt, which will look something like this: "nama sax ('h' for help)>" In this instance, 'sax' is the current track. When using buses, the bus is indicated before the track: "nama 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. Many effects have abbreviations, such as 'afx' for 'add_effect'.
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 Master 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 Each track, including Master and Mixdown, has its own REC/MON/PLAY/OFF setting. The MON setting means that the track source is connected to the track input, and the track output is supplied for monitoring by the Main bus and other submixes if any. The REC setting prepares the track is ready to record a WAV file. The PLAY setting enqueues an audio file for playback from disk as the track source. REC and PLAY settings also create the monitoring routes associated with MON status. OFF setting tells Nama to remove the track from the audio network. OFF status also results when no audio source is available. A track with no recorded WAV files will show OFF status, even if set to PLAY. 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 WAV 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 WAV files recorded in the same run have the same version numbers. The version numbers of files for 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 setting. Setting the track version to zero restores control of the version number to the bus. The Main bus version setting does not currently 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. 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, applying effects, adjusting volume, etc. Currently, regions are not clipped out of their host track. This feature may be implemented in future. 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 Nama allows you to place fades on any track. Fades are 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. Bunch names are used with the keyword "for" to apply one or more commands to several tracks at once. A bunch can be created with the "new_bunch" command. Any bus name can also be treated as a bunch. Finally, several system defined bunches are available: rec, mon, off All tracks with the corresponding setting in the current bus Buses Sub 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.
General Notes While Nama can address tracks by either name and track number, the chain setups use the track number exclusively. The Master track (mixer output control) is always chain 1, the Mixdown track is always chain 2. In single-engine mode, 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. In dual-engine mode, JACK ports are used for interconnections instead of loop devices. Flow Diagrams The following diagrams apply to Nama's single-engine, mode. (The same topology is used in dual-engine mode.) 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 track number/name. The stereo outputs of each user track terminate at Master_in, a loop device at the mixer input. Track, REC status Sound device --+---(3)----> Master_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, or if "rec_disable" is issued. Track, MON status sax_1.wav ------(3)----> Master_in Mixer, with mixdown enabled In the second part of the flow graph, the mixed signal is delivered to an output device through the Master chain, which can host effects. Usually the Master track provides final control before audio output or mixdown. Master_in --(1)--> Master_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 Master track signal as input and provides an output to the soundcard or WAV file. +- Low -+ | | Master_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 "Master off"). Mixdown proceeds after you start the transport. As a convenience, Mixdown_nn.wav will be symlinked to <branch_name_nn.wav> in the project directory. (If git is disabled or not available <project_name_nn.wav> is used instead.) Corresponding encoded files are created if the "mixdown_encodings" option is set. Acceptable values are a space-separated list. The default is "mixdown_encodings: ogg mp3". The Preview and Doodle Modes, and the Eager Setting 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. These modes are unnecessary in Nama's dual-engine mode. Saving Projects The "save" command is the usual way to preserve your work. When you type "save", Settings related to the state of the project are saved in the file State.json in the current project directory. State.json is tracked by git. "save" updates several other data files as well: Aux.json, in the current 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, 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 When git is installed, Nama uses it to store snapshots of every step in the history of your project. While you can continue using the same "save" and "get" with snapshots, the underlying version control gives them huge advantages over files: (1) they can sprout branches, (2) they retain their history and (3) they are never overwritten. 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) While the merging of branches may be possible, the function has not been tested. 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 WAV file, allowing you to fix wrong notes, or substitute one phrase for another. Each track can host multiple edits. Edits are non-destructive; they are achieved by using Ecasound's ability to crossfade and sequence. Select the track to be edited and the correct version. Before creating the edit, 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. Provide marks as arguments to new_edit (not implemented) Type new_edit play_start_mark rec_start_mark rec_end_mark.) 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. You may specify another range for editing and use the editing procedure again as many times as you like. Edits may not overlap. Merging edits merge_edits will recursively merge all edits applied to the current track and version, creating a new version. I recommend that you merge edits when you are satisfied, with the results to protect your edits against an accidental change in mark, region or version settings. restore_edits acts on a merged version of the current track, selecting the prior unmerged version with all edits and region definitions in "live" form. You may continue to create new edits. TO BE IMPLEMENTED list_edits will label the edits by index and time. end_edit_mode will restore normal playback mode destroy_edit 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 one track object.
You can send now send commands from a remote process, and also get information back. 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. If the result is an object or data structure, it will be returned in a serialized form. For example, if you send this string: eval $this_track->name The return value will be the name of the current track.

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.
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.
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.
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.
The Nama mailing list is a suitable forum for questions regarding Nama installation, usage, bugs, feature requests, etc. http://www.freelists.org/list/nama For questions and discussion related to Ecasound https://lists.sourceforge.net/lists/listinfo/ecasound-list
The modules that make up this application are the preprocessed output from several source files. Patches against these source files are preferred.
