- Update to version 2.16
* New:
+ plot mode, which displays average of FFT bins.
+ "Fill" plot mode, which displays both maximum & average of
FFT bins.
+ "Histogram" plot mode, which displays distribution of FFT
bins.
+ Selectable plot scaling: dBFS, dBV/RBW, dbV/√Hz, dBm/RBW, dBm/Hz.
+ Min hold line in plot.
+ A/B measurement markers on plot.
+ Plot tooltip displays delta from demod frequency.
+ Dropped frames are indicated by red background in
FFT Settigns panel.
+ "Avg" waterfall mode, which displays average of FFT bins.
+ "Sync" waterfall mode, which mirrors averaged data from plot.
+ Support for RTL-SDR Blog V4 in AppImage and DMG releases.
+ Save FFT plot center frequency in settings.
* Improved:
+ Peak detection algorithm.
+ Peak detection uses peak hold data when available.
+ Maximum FFT size increased to 4M.
+ Maximum frame rate increased to 500.
+ Averaging slider is consistent across frame rates.
+ Visibility of text in axes.
+ Full support for high-DPI screens in plot & waterfall.
+ Plot & waterfall performance.
+ Plot can be zoomed & resized while DSP is stopped.
+ FFT window setting is stored as a string.
+ Waterfall span setting is stored in milliseconds.
+ Added 6 dB attenuation to WAV file recordings to prevent
clipping.
+ Use logarithmic scale for frequency zoom slider.
+ Reduced CPU utilization of demodulators.
+ Properly handle smooth scrolling.
+ Shorten band names to fit in narrow spaces.
+ Delay plot & waterfall drawing until samples arrive from
hardware.
* Changed:
+ Frequency zoom slider zooms around center of display.
+ Disallow scrolling beyond the FFT frequency limits.
+ Default narrow FM deviation increased to 5 kHz.
* Fixed:
+ Time on waterfall is calculated correctly.
+ Frequency is correctly rounded in I/Q filenames.
+ Crash in AFSK1200 decoder.
+ Hang when setting a very narrow filter width.
+ Inconsistent 1-2-5 scaling of amplitude axis.
* Removed: "Save waterfall" feature.
