CMRC SoundScape is a simple to use sound management system that has been designed primarily to allow the playing of sounds on an Android tablet while operating a model railway layout. Having said that it can be used for playing any types of sound or music tracks. For best effect the tablet should be connected to an externally powered speaker either via Bluetooth or via the 3.5mm jack socket. It was created using MIT App Inventor 2 and tested and developed on a Nexus 7 2013 running Android 5 Lollipop. Up to 30 'background' sounds can be played at intervals or in a continuous loop with each sound having its own volume control. While these 'background' sounds are playing up to 30 more manually selected sounds can be played. Of these 30 manually selectable sounds up to 10 sound sequences can be defined with up to 6 sounds per sequence. Up to 10 Public Announcements (PA) can be predefined with one extra ad-hoc PA available for 'on the fly' announcements. These PAs can be prefixed with a chime sound if required. From version 11 there are two playing modes. The default mode is Master which operates in the same way as previous versions in that all sounds are played on the local device. If CMRC SoundScape has been installed on another Bluetooth paired Android device and has been setup to run as the Slave then the sounds can be played on that device.
