opengl - How to start writing a music visualizer in C++? -


I'm interested in using OpenGL and I had the idea of ​​writing a music visualizer. Can anybody tell me some elements that I need an element and how should I go about learning about doing this?

If you use C ++ / CLI, then that is WPF Four (Fourier Joe ;;) uses the display. / P>

She has enough information about you in those references that ask you, is a line from a specific page here;

How do we split sound in frequencies? Our ears do it in a mechanical way, mathematicians use it fourier transforms, and computers use FFT.

  1. Sound physics 1.2. Harmonic Oscillator
  2. Sampling Sample
  3. Fourier Analysis
  4. Complex Number
  5. Digital Fourier Conversion
  6. FFT

Ah, I got it after a few minutes, it is a basic C ++ analyzer. The code is included, which you should stop and walk.

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName (). ToUtf8 (). ConstData () & lt; & Lt; Std :: endl; QAudioInput * default_device = new QAudioInput (device_info, format); QIODevice * default_io_device = default_device-> Start (); a QAudioInput.setVolume () method is not you I ...
