* start bandpass filter in new process and make it abortable
* hardcode esc key, as QKeySequence.Cancel not avail on older Qts
* Default to Esc if QKeySequence.Cancel not available
* add missing space
* make filter methods static
* move multiprocessing method to top level for multiprocessing
* make coverage multiprocessing agnostic
* update coveragerc
* add test for filter abort
* show getting start hint in interpretation
* add test for creating spectrogram
* add spectrogram page to signal frame
remove parent frame property from epic graphic view
* prototype for spectrogram drawing (has performance issues)
* enable yscale for spectrogram
* regen file
* enhance spectrogram performance by using QImage
* enable y scale for spectrogram
* add initial legend to spectrogram
* fix colormap location
* remove colormap legend
* add more colormaps
* make colormap configurable via ini
* make colormap configurable in settings
* make fft window size configurable
* rescale Y on signal frame resize
* adapt unittest to new api
* allow y move with drag for spectrogram view
* refactor painting backend
* enable vertical selection in spectrogram graphic view
* spectrum: fix order of y values
* use fliplr for compat
* add bandpass filter function
* add narrowband iir filter
* set lower bandwidth for test
* add windowed sinc to filter class and adapt unittest
* change default of hold shift to drag
This way making a selection does not require a key modifier by default
* add fft convolution
* add performance test for fft convolution
* speed up performance test
* fix error for small data sets
* add test for filtering channels
* use astype for compatibility with old numpy versions
* refactor context menu of graphic views
* remove fft convolve performance test to avoid random fails on CI
* fix spectrogram calculation
* fix spectrogram calculation
* improve stft performance
* show samples in view for spectrogram and allow deeper zoom
* enable zoom to selection for spectrogram
* enable start end and selection infos for spectrogram selection
* enable bandpass filtering from spectrogram
* fix selection start end behavior for spectrogram
* update spectrogram infos in start end edited
* add unittest for channel separation
* enhance architecture of spectrogram management
* add class SpectrogramSceneManager
* cache spectrogram
* fix x axis orientation
* move scene managers to painting
* redraw on fft size update
* add lod slider for spectrogram
* remove unused stuff
* add tooltip for lod slider
* update selected bandwidth on sample rate changed
* add update for gv signal on resize
* fix fftshift parameter
* remove xflip as this is corrected by fftshift now
* remove lod slider as it leads to confusion and low lods are hard to see
* clip f_low and f_high
* update spectrogram images on colormap change
* set loading cursor right before bandpass filtering signal
* add select all action with ctrl+a to graphic views
* use parameters from original signal for newly created signals
* fix noise level in unittest
* improve spectrogram performance by splitting image into segments
* avoid division by zero
* fix unittest
* improve signal redraw on resize
* add created signal right under original signal
* adapt unittest to filtered frame created under original signal
* add dialog for configure bandwidth and display default values
* make bandwidth configurable
* fix spectrogram scene rect for small signals
* make data min and data max for spectrogram configurable
* use object names for indexing settings as texts are not reliable
Some OSes insert & before texts probably for shortcuts
* use heuristic to choose normal or FFT convolution
* suggest a filename for unsaved signals based on their name
* fix subpath range calculation
* use window for subpath drawing to avoid flickering colors
