im currently totally into sound creation and signal analysis using fourier-transform
i try to make an animated screensaver for audio-files
UPDATE: I moved the project to GitHub, so just download the whole thing as zip, dont know how big
I compiled it on Windows 7 x64 Home Premium dont know if it runs on 32-bit, but i guess not.
If u like to compile it yourself on Windows get msys, mingw_w64 4.8.2 sjlj, codeblocks and extract all libraries found in BenniSDK/lib folder, which are
compiled with mingw_w64 sjlj ( i chose sjlj due to better compatibility with linux )
It still runs with SFML, but i happened to compile PortAudio with all major Windows sound APIs ( ASIO, Wasapi, DSound, WMME, WMPKS ), so much better times are coming and hopefully in the near future one can choose the soundcard himself ( will start to work on a SoundOptionDialog )
Project Binaries ( bin + media ) https://github.com/benjaminhampe/BenniSDK-demos-x64/
Whole Project ( bin + media + src + libs) https://github.com/benjaminhampe/BenniSDK/
There are lots of improvements, the speed is more than doubled ( due to less drivercalls and less allocations )
+ I added some GUI to manipulate the most important parameters ( Matrix size, dB scale, fft-size )
+ U can now switch between linear and logarithmic display-mode
+ I added fltk -> use the fltk exe which is more uptodate
+ main classes are FourierTransformRtoC, IAudioPlayer, CAudioPlayerSFML, CGUIAudioPlayer, CMatrix, CMatrixSceneNode and AudioAnimator3d_App
- I dont get the previewtex (waveform) working on program start, u have to load a file to make it work ( dont know why, if somebody knows, tell me )
Have fun
