Parameters

float_samples	A buffer containing normalized (from -1 to 1) float audio samples
num_samples	Number of audio samples
sample_rate	Audio sampling rate in Hz
thresholds	Quality checking thresholds that will be applied to the output quality check metrics

Returns

Quality check result

Exceptions

std::runtime_error	if runtime error occurred
voicesdk::LicenseException	if license error occurred
