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.
