Roadmap

architecture

upgrade to C++ v11
upgrade to Qt 5.5/5.6
change data buffers to QVector
Signal class (events: ColorChanged, NameChanged, PositionChanged, GetFFTValues)
MVC: Signal, HistogramView, WaveformView, HistogramRuler, WaveformRuler, etc.
signal colors:
- make them consistent (same in waveform viewer and power spectrum)
- save and load RGB values in the montage file (with backward compatibility)
- create new palette for them and verify if they all look good on our background
merge drawWidget and drawWidgetToPrinter
rename the PowerSpectrum (signalcurve) to HistogramView
rename the Waveform (viewsignal) to WaveformView
merge the dockable and non-dockable power spectrums
draw histogram and waveform views on separate threads
open stream directly from a device or TCP port (not an EDF file)
common interface for file converters
let the controls access the not-visible part of the data
allow only two themes: one for screen and one for printing (and remove all the “print ifs”)
move files into folders based on their function (models, views, controllers, file converters, etc.)
make it compilable with MSVC and Visual Studio

always display the high and low of the vertical and horizontal axis
end value as clickables to change the range of an axis
linear value to be formatted (to show thousands)
cursor: display unit
doubleclick to reset zoom and position
vertical axis mouse wheel zoom
- change w,h,bordersize to QRect chartArea
vertical text on the vertical axis,
new text format: linear/logarithmic name (unit)
vertical axis name: intensity
support for “signal not available” at certain points
right click: dropdown menu (print, save as png, cursor)
automatic and dynamic fft size calculation
multi-signal power spectrum
- same signal, same color
- colorful signal selector (on the left)
cursor redesign
- follow mouse
- display crosshair
- values in color boxes
signal averages
- detach fft sample size from the displayed data in the waveform viewer
- sample timescale selection (3 sec/30 sec/3 min)
sample and compare
fix the FFT calculation bug
right-click+mouse move: zoom the axes
double-click: reset zoom
indicate peaks with a cursor
make sound if condition is present
limit the framerate
left click: add new cursor or remove existing
always display the crosshair if the mouse is close to a curve
Bezier-curve

real-time playback
add audio/video recording (on Windows too)
update third party libraries (fidlib and kiss_fft)
create a new change value dialog
new splash screen picture (EDFBrowser Pro)
fft theoretical limits: 1sec sample: 1hz, 3sec sample 0.3333hz. max hz: sample rate/2
statistical data, user feedback collection (rating, bug report, feature request)
automatic update notification
