FalseStereoDetector
streaming mode | Audio Problems category
Inputs
- audio (stereosample) - the input audio
Outputs
- isFalseStereo (integer) - a flag indicating if the frame channes are simmilar
- correlation (real) - correlation betweeen the input channels
Parameters
- correlationThreshold (real ∈ [-1, 1], default = 0.9995) :
- silence threshold. Silent frames will be skkiped.
- frameSize (integer ∈ (0, ∞), default = 512) :
- desired frame size for the analysis.
- silenceThreshold (integer ∈ (-∞, 0), default = -70) :
- correation computation can be skipped if not required.
Description
This algorithm detects if a stereo track has duplicated channels (false stereo).It is based on the Pearson linear correlation coefficient and thus it is robust scaling and shifting between channels.
