a558565886 Further template BlockDecimator by element type, use for audio buffer.
Appropriating for use as a buffer accumulator that will save up enough audio samples to put into an audio DMA buffer.

d821afc60d Spectrum streaming control, spectrum attributes back in each frame.
TODO: This feels kinda complex, and there's some repeated Processor code that needs to be refactored into a base class.

d9017530c6 Moved baseband temporary buffers back into class member variables.
Significant performance hit when declaring on stack. C++ wants to initialize std::array or even raw array with element constructors, was resulting in ~7% CPU utilization, for a buffer that was immediately written over anyway.

It's temporary, after all...

0962343190 Use decimation variable, not hard-coded value.
Break in form from NBFM code.

7de80edcd3 Move baseband FIR filter defs to common file.
They will likely be shared with multiple decimators/demodulators.
Also added normalized filter pass/stop values to each set of taps.

bbfcca8ec0 Rebake of AM, NFM demodulators -- more flexible filtering/configuration.
Also make SpectrumCollector dynamically configurable.
Add deemphasis filter to NFM.
