Audio / Re: Audio output only on one channel

« on: July 08, 2020, 10:35:35 pm »

I tryed it with two cards now (USB audio card and direct), but on the same pc - same effect.
I will try on an other pc tomorrow.

btw: you can also hear it, if you are running two different frequences on each ear. example: a sinus wave with 60 and 70 HZ. Only if you have both ears on the headphone, you should hear a 10HZ benaural wave. Otherwise not. In this test, jou can hear this 10HZ wave on each single ear - which should not be the case.
If this works fine in your setup, it must be an problem of my hardware.
best and thanks so far.

Not a big change, but this has the same effect / error.
Still a little bit of sound in the other channel as well.

  sf::SoundBuffer buffl;
   vector<sf::Int16> samplesl;
   for (int i = 0; i < 44100; i++)
   {   
      samplesl.push_back(SineWave(i, 324, 1));
   }
   buffl.loadFromSamples(&samplesl[0], samplesl.size(), 1, 44100);
   sf::Sound soundl;
   soundl.setBuffer(buffl);
   soundl.setLoop(true);
   soundl.setPosition(-1, 0, 0);
   soundl.play();

Audio driver sounds reasonable. It is not stereo, but somhow quiet on the other ear. room correction is deactivated.

   sf::SoundBuffer buffl;
   vector<sf::Int16> samplesl;
   for (int i = 0; i < 44100; i++)
   {   
      samplesl.push_back(SineWave(i, 324, 1));
      samplesl.push_back(0);
   }
   buffl.loadFromSamples(&samplesl[0], samplesl.size(), 2, 44100);
   sf::Sound soundl;
   soundl.setBuffer(buffl);
   soundl.setLoop(true);
   //soundl.setPosition(-1, 0, 0);
   soundl.play();

Audio / Audio output only on one channel

« on: July 07, 2020, 03:31:02 pm »

Hey,
I try to bring a SoundBuffer to only one channel (stereo left/right).
I tryed the following:

• create it wich two channels, only fill in every second value. -> sound is still on both ears.
• using setPosition(-1, 0, 0); to move the sound to left. -> still some sound (but more quiet) on the right ear

Is there any possibillity to split Buffers to different channels without impacting the other channel? Some low level functionality?
Thanks
