Create a log_{10}(|fft|²) stream chain, with real or complex input.

## Parameters[edit]

(*R*): *Run-time adjustable*

- FFT Size
- Number of FFT bins

- Reference Scale
- Sets 0 dB value input amplitude

- Frame Rate
- Output frame rate

- Average (
*R*) - Whether to average [True, False]

- Average Alpha (
*R*) - FFT averaging (over time) constant [0.0-1.0]

## Example Flowgraph[edit]

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.
