- Rewrite graph code taking advantage of the y axis data.
- Add save function to oscilloscope and spectrum.
- Use time instead of samples in oscilloscope.
2023-10-24
----------
- Add simple moving average in spectrum view.

- Remember selected device in configuration window.
Code was contributed by user Johannes.
2023-04-09
----------
- Add mono channel support as requested by users.
- Refactor several files.
- Drop frequency measurement in oscilloscope - spectrum does it now
and can be run in parallel. Gives better resolution and magnitude.
2022-10-09
----------
- Update README with binaries installation and Visual Studio instructions
- Fix frequency response export in Windows
- Add Visual Studio and MSVC support
- Update RtAudio to 5.2.0
- Increase font size in legend
2022-04-20
----------
- Display base frequency, magnitude and THD in spectrum.
- Add Blackman-Harris window function.
- Increase resolution (> 16 bit) using floating point audio data.
- Catch more errors to avoid crash.
- Compile in DirectSound and WASAPI on Windows.
- Use timer loop instead of sleep for frequency response.
2021-11-04
----------
- Reformat README.md and fix instructions.
- Update to latest RtAudio.
- Switch to WASAPI on Windows.
- Add package creation with CMake.
- Set CMake build type to Release as default.
- Add build instructions for MacOSX.
- Fix Blackman window function.
- Display RtAUdio info in About popup.
- Compile Linux with Alsa and Pulseaudio support.
- Avoid crash when sound card channels are mono or missing.
2021-03-14
----------
- Use pulseaudio on Linux up to 192000 samples/s.
- Catch sound card issues and show message in initialization.
- Optimize screen repaint.
- Improve graph and legend display.
- Add Debian package support in CMake.
- Add compiling instructions for Linux and Windows 10.
- Add white noise to generator.
- Use RMS level in frequency response instead of peak.
2020-09-24
----------
- Improve FFT interpolation.
- Add second channel to frequency response.
2020-07-01
----------
- Migrate to CMake.
- Migrate README to markdown and move change list to NEWS.
- Migrated project from subversion to git.
2019-09-25
----------
- add FFT window functions Hanning and Blackman.
- add spectrum scaling according to sample rate.
- modify spectrum view 10 Hz - 100kHz, 0 - -100 dB.
- fix sound card dialog (available frequencies).
2019-09-22
----------
- update RtAudio to version 5.1.0
2018-??-??
----------
- Updated code to compile with current compilers on Linux.
- Updated code to compile with recent versions of rtaudio and
wxWidgets.
- Documented the choice of GNU GPL v2+ as source license.

2008-08-27
----------
- sound card switching works; but problems when using different sound cards
for input and output
2008-08-26
----------
- changed colors for numbers in scopes
- OSC - L channel measures frequency - FFT

- wxTextCtrls do not react to ENTERs
- SA - variable FFT length
- SA - right channel is added
- SA - averaging of FFT values introduced
2008-08-22
----------
