A method of point cloud attribute coding performed by at least one processor, including obtaining an encoded bitstream corresponding to a point cloud; determining whether the encoded bitstream was encoded using an inter-channel tool for inter-channel decorrelation; based on determining that the encoded bitstream was encoded using the inter-channel tool, decoding the encoded bitstream using the inter-channel tool to reconstruct an attribute signal corresponding to the point cloud; and reconstructing the point cloud using the reconstructed attribute signal.
