Choose the right value to trade off between accuracy / speed. The larger the numvalues, the more CPU the FFT will take. See FMOD_DSP_FFT_WINDOW for different types of fft window techniques possible and for a more detailed explanation. This filters the PCM data before entering the spectrum analyzer to reduce transient frequency error for more accurate results. If the signal is multichannel (such as a stereo output), then this value represents which channel to analyze.

Max = 8192.Ĭhannel of the signal to analyze. Size of array in floating point values being passed to the function. Decibels = 10.0f * (float)log10(val) * 2.0f See remarks for what the data represents. This is an array of floating point values. Retrieves the spectrum from the currently playing output signal.Īddress of a variable that receives the spectrum data. There is FMOD function to do this, I need something similar: In my version I am using getSpectrum function, taking from it amplification of low frequencies and doing some arithmetics to use it to setPosition of cam. Now I want to use irrKlang, but I don't know how to get sound spectrum. I know only msvc on windows, but my game will be released as FreeSoftware, so I don't want use any propertiary tools. So there is two ways to fix this problem: use C interface or use other compilator. I googled some and found that this is impossible to compile under mingw, I can't use C++ interface, because linker throwing tons of undefined references. The problem is, that library that I used (FMOD) have one problem in Windows. (camera is waving some in same ways, but I will repair it). I needed to make a waving camera to the sound that is playing.Įverything is good, you can watch results here: Some time ago I was writing and testing some code for my game.
