* @GST_AUDIO_TEST_SRC_WAVE_TICKS: periodic ticks
* @GST_AUDIO_TEST_SRC_WAVE_GAUSSIAN_WHITE_NOISE: white (zero mean) Gaussian noise; volume sets the standard deviation of the noise in units of the range of values of the sample type, e.g. volume=0.1 produces noise with a standard deviation of 0.1*32767=3277 with 16-bit integer samples, or 0.1*1.0=0.1 with floating-point samples.
* @GST_AUDIO_TEST_SRC_WAVE_RED_NOISE: red (brownian) noise
+ * @GST_AUDIO_TEST_SRC_WAVE_BLUE_NOISE: spectraly inverted pink noise
+ * @GST_AUDIO_TEST_SRC_WAVE_VIOLET_NOISE: spectraly inverted red (brownian) noise
*
* Different types of supported sound waves.
