Spectrum Analyzer

By: pqyt

New: Implemented a first version of a Constant-Q transform (CQT). Default is still FFT.
New: A custom FFT size can be specified in the configuration dialog.
New: A sample rate-based FFT size can be specified in the configuration dialog. The FFT size will be calculated based on the duration specified and the sample rate of the track being played.
New: Implemented Mel scale mapping of the FFT coefficients.
New: X-axis and Y-axis can hidden by selecting the "None" mode of each of the axes.
Improved: Added a versioning mechanism to the settings of the component. Unfortunate side-effect: Any configuration will be reset.
Improved: Tweaked the layout and the size of the configuration dialog a little bit.
Improved: Removed the client edge of the window for a cleaner look.
Fixed: The configuration dialog disabled the decibel settings when selecting a logarithmic Y-axis scale.
Fixed: Opening the visualization when a track was already playing did not show the spectrum.

Supported systems: Windows 32-bit, Windows 64-bit.
