Log Power FFT

Create a log10(abs(fft)) stream chain, with real or complex input.

Parameters

(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

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.
