In some examples, the invention refers to improved stereo coding. An encoder provides an encoded representation of an audio signal. The encoder applies a spectral whitening to a separate-channel representation of the input audio signal, to obtain a whitened separate-channel representation of the signal. The audio encoder applies a spectral whitening to a mid-side representation of the signal, to obtain a whitened mid-side representation of the signal. The audio encoder decides whether to encode the whitened separate-channel representation of the signal, to obtain the encoded representation of the signal, or to encode the whitened mid-side representation of the signal, to obtain the encoded representation of the signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"MDCT M/S stereo","description":"The invention refers to audio encoders, audio decoders, and audio encoding methods and audio decoding methods.
