Quick Start Guide

This is a short introduction into the basic concepts of The LAMA Audio Measurement Application.

Audio Settings

First you might want to setup your audio-interface. The Audio Settings window can be opened in the View menu or with the keyboard shortcut Command-Return.

In this window you can change the device being used and some of it's properties like sample-rate and clock source and launch the configuration application for the current device.

Further it is possible to

Most of these functions can also be accessed with the Audio Settings Toolbar Menu in the Main Window.

Audio Settings Window

The Main Window

The Main Window mainly shows two tables: the upper one holds all currently active instruments, the lower one those which have been used recently and are no longer active.

Current Instruments

The "Current Instruments" table shows a little checkbox next to the name of the instrument - it is here to hide instruments.
An instrument's title can be renamed by double clicking it's name in the instruments table - this changes the window title and can be useful to achieve a better overview when a lot of instruments of the same type are being used. There is also a little arrow in this table, click it to make this window the frontmost window of all instruments.

Recent Instruments

The lower table in the main window holds those instruments which have been used recently and are no longer active. These instruments can be restored with a double click in the "recent instruments table".

Closing vs. hiding Instruments

Usually when an instrument window is closed, the instrument is removed from the signal processing chain and will no longer consume CPU power. Sometimes it can be necessary to hide an instrument - moving it off screen but keeping it "alive", e.g a recorder that should record but should not appear on the screen.


Basic Concepts

Instruments in LAMA have one or more audio-inputs and analyze the signal that is fed into them. Although every type of instrument is different, they share some common approaches which should be discussed here.

Settings Window and View

Every instrument has some different settings and there are two different places where to adjust them:

  • Settings View: The settings view holds the more important parameters of an instrument. It appears automatically when you move the mouse into the lower area of an instrument window.
  • Settings Window: The more detailed settings appear in the settings window, which is shown when clicking the gear icon in either the settings view or window title-bar, or pressing Command-I on your keyboard.

The auto-appearance of the settings view

If someone is not happy with settings-views appearing automatically when moving the mouse in the window, it is possible to change LAMA's behavior in the Preferences window by checking the show settings view only with double click setting. When it is on, it is necessary to double-click into the instrument view to show or hide the settings view.

It should be noted, that not all instruments do have a dedicated settings window and that the Transfer Analyzer makes a little exception, as it's settings appear in the instrument window's sidebar.

Workspaces, Saving & loading Sessions


A set of instruments can be saved in a workspace, which can be recalled (also with a assignable key-command) Especially with smaller screens this can improve your workflow.

Excluding Instruments from Workspace recalls

Instruments can be put in a sticky mode, which excludes them from workspace recalls. This is achieved with the lock icon in the instruments's window title bar.


LAMA's state (and the state of all instruments) can be saved in a session to disk (filenames have the extension .lama). These sessions can be loaded with the File - Open command.

Last Session File

When LAMA quits, the current state is automatically saved into a file in the Application Support folder. When launched again, LAMA will load this file and appear exactly in the same state how you left it. Note that these auto-saved session files are audio-device dependent: this means LAMA will restore the state it has been with the audio-device currently in use.

Session loading when changing Audio Device

As mentioned above, there is a file on disk that represents a session specific to an audio hardware device. When the audio-device s is changed in the Audio Settings window, LAMA will prompt a dialog asking if the file corresponding to the new audio-device should be loaded.
