The aim of Economy level audio object is to detect the absolute peak level in the input signal. The audio object algorithm is primarily used for reducing the level of the background music track during announcement. The EconomyLevel block is a control source generator for the Ducker object. It should be inserted separately into the signal path that is supposed to control the Ducker object and connected to the main Ducker object via control routing.
The word ‘Economy’ in the block names reflects the original names used within Studer OnAir Micro console firmware. These blocks are optimized for performance and are suitable for using with mixer consoles and performance-constrained embedded devices.
Economy level Control output depends on block length selected and input audio frequency.
Since economy level works on the data from one block of data presented to it, for lower block length and lower frequencies control output may not be static.
The basic features for the Economy level Object are:
- Integration with the xAF.
- Accessibility from the Signal Flow Designer Software. This allows the user to add the object within an audio pipeline.
- Fixed number of channels from within SFD. The number of input channels are always equal to the number of output channels
- The object has one control output channel
- Implementation on generic code.
- In-place computation support.
