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.

1aa391bac8 Whoops. Revert to baseband -O3 compiler flag.

58e6d26910 Move AudioOutput back to inside audio processor classes.
Was wasting precious RAM making it static. I lose 400 bytes of .text, not sure why, but I think the trade is worth it.

731cea1b96 Move event.* code into event_m[04].*.
Slightly more duplication of code now. Need a base class...

Jared Boone
1f3c182b7f Add missing message handler for wideband spectrum.
Spectrum processing was not enabled, and hence wideband spectrum was not being displayed.

64966d4539 Fix NaNs coming out of angle_approx_0deg27().
Used in FM demodulator, was causing downstream problems when using the floating point values directly.

497adda390 IIR default constructor passes no audio.
Debugging mechanism -- filter must be configured to pass audio.

Jared Boone
4ea84301c6 For non-audio modes, don't bother muting audio.
It's assumed base class will start with audio muted.

d6f797540d Remove baseband message from queue after it is processed.
Application code can now wait on queue empty and know the baseband's state.

136ba895ef Clear spectrum FIFO when streaming is stopped. 2016-01-10 11:00:09 -08:00

62e5ec1dbb Postpone clearing channel_spectrum_request_update until finished with data in array.
There was potential for new samples to be copied into array as the FFT and post-processing were occuring.
