denny	f0dc9452c8	Resolves issue with correct display and scaling of decibel values in ... both the spectral and waterfall displays. Resolves issue with gain loss in HilbertTransform.	2015-11-08 08:17:34 -05:00
denny	70e62ebb35	Adds airspy USB tuner support and updates the spectral display ... component. -Airspy supported with 10 and 2.5 MSps sample rates. Additional decimation may be added later. -Spectral display updated to include smoothing and filtering options. Note: the decimated output of a tuner channel from the airspy is 48,076.9 samples per second, versus the normal 48 kHz decimated rate. This is 1.0015 times the normal rate and doesn't appear to impact the decoders or audio processing. Therefore, no fractional resampling has been added.	2015-11-07 08:18:41 -05:00
dennis.sheirer	4e0fd9b7b0	Channel Spectral Display ... - Adds Channel Spectrum tab to display FFT of the audio output of the currently selected channel - Upgrades to JTransforms 3.0 FFT library - Adds three new context menus to main and channel spectral displays: -- Baseline - affects the vertical rendering baseline of the FFT -- Amplification - affects the vertical height of each FFT bin -- Averaging - affects how many FFTs are averaged to produce the display	2014-09-06 14:58:05 +00:00
