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.
