Symetrix has released the latest version of its free Composer programming software for Edge, Radius NX, Prism and Solus NX DSPs – Composer 8.0 for Windows expands the Symetrix ecosystem with new features including Lua Scripting, Radius NX AEC Enhancement, Audio Playback and Media Manager.

Symetrix Composer 8.0Composer 8.0 has been enhanced with Lua scripting, allowing users to create custom Intelligent Modules for Composer. These Intelligent Modules allow the software to control and monitor any device that can be controlled by a third-party control system or provide system logic functionality which previously required large and complex logic programming. Implementing the same functionality with Lua scripting is a simple task that can be programmed and tested in a few hours.

Intelligent Modules created using Lua Scripting in Composer 8.0 are identical to the native Intelligent Modules delivered with Composer, and work with both new and existing Symetrix devices compatible with Composer. There is no activation or licencing fee for creating or using Lua scripted Intelligent Modules in Composer.

The Acoustic Echo Cancellation (AEC) cards for the Radius NX have a new configuration option that increases the total number of AEC channels when using discrete AEC references. When processing AEC, the AEC channels in each room need to receive an AEC reference signal specific to that room which presents an increased processing load for the DSP chip.

With Composer 8.0 the Radius NX with AEC-2 card is now capable of up to 12 channels of simultaneous AEC. This enables a single Radius NX to powerfully manage as many as 12 different rooms. The increase in AEC capability may also be realized in existing installations where Radius NX DSPs with AEC cards have been installed, requiring only a firmware update. The Radius NX with AEC-1 card is now capable of processing 6 discreet AEC references.

Audio recording functionality in the Radius NX is now joined by audio playback. Audio systems often include a message playback device for audio cues such as classroom bells, airport parking messages, retail store closing announcements, or background music. The Radius NX can play up to 8 audio tracks simultaneously from a local USB drive.

Each audio playback module in the Radius NX can include up to eight channels of audio up to a combined total of eight tracks per Radius NX. Playback modules are individually controlled for manual or automatic playback, track/playlist selection, loop, shuffle, repeat, and auto start. Support is provided for multi-channel audio files including LCR, 3.1, 5.1, and 7.1 recordings.

Total audio playback time for the Radius NX is dependent on the size of the USB drive being used. A 512GB drive can provide more than 1,600 hours of CD-quality playback for less than US$75, and there are no fees to activate or enable playback functionality.

The Radius NX Media Manager is a browser-based feature providing upload, download, playlist, and organization functions for recordings on the USB drive of the Radius NX. Whether a Radius NX is playing background music, announcement messages, or timing chimes, audio files need to be uploaded to the Radius NX before they can be played and organised on the drive.

As with audio recording, audio files on the Radius NX can be accessed with an FTP client connected to the Radius NX, but Radius NX Media Manager also provides full control of all media files on the device using any web browser. By accessing the Radius NX with a web browser, a user can upload files from a computer to the Radius NX, organize those files into folders for easy access, create and organise playlists as needed, and move audio files individually or in groups to simplify building or maintaining an audio library for the Radius NX. The Radius NX Media Manager is available for free on any Radius NX by updating to Composer 8.0 and connecting a USB drive.
