FalseStereoDetector
standard mode | Audio Problems category
Inputs
- frame (vector_stereosample) - the input frame (must be non-empty)
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) :
- threshold to activate the isFalseStereo flag
- silenceThreshold (integer ∈ (-∞, 0), default = -70) :
- Silent frames will be skkiped.
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.
