SoundTest

This is basically what the core of the program is:

ioctl(fd, KIOCSOUND, static_cast<int>(CLOCK_RATE / frequency));
std::this_thread::sleep_for(std::chrono::milliseconds(duration));
ioctl(fd, KIOCSOUND, 0);

Where fd is the file descriptor of the audio device, CLOCK_RATE is the clock rate of the PC speaker, frequency is the frequency of the sound, and duration is the duration of the sound.

The KIOCSOUND constant is set in linux/kd.h.

Notes

  • For SoundCloud importing, you need an OAuth token from SoundCloud. You can get one here. Set the SOUNDCLOUD_API_KEY environment variable to that OAuth token.
  • A workaround is to play a track on SoundCloud in your browser, then open developer tools and copy the value of the oauth_token cookie. This is your OAuth token as well.
