Compute a running average of the magnitude squared of the the input. The level and indication as to whether the level exceeds threshold can be retrieved with the 'level' and 'unmuted' accessors.
Use with the function probe block. Available functions to probe: level(), unmuted()
If the type is set to Complex->Float, the block will also output the values computed.
Parameters
(R): Run-time adjustable
- Threshold (dB) (R)
- Threshold for muting.
- Alpha (R)
- Gain parameter for the running average filter.
Example Flowgraph
Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
