FalseStereoDetector¶

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.

Source code¶

• C++ source code

• C++ header file
