+/**
+ * @file cook.c
+ * Cook compatible decoder.
+ * This decoder handles RealNetworks, RealAudio G2 data.
+ * Cook is identified by the codec name cook in RM files.
+ *
+ * To use this decoder, a calling application must supply the extradata
+ * bytes provided from the RM container; 8+ bytes for mono streams and
+ * 16+ for stereo streams (maybe more).
+ *
+ * Codec technicalities (all this assume a buffer length of 1024):
+ * Cook works with several different techniques to achieve its compression.
+ * In the timedomain the buffer is divided into 8 pieces and quantized. If
+ * two neighboring pieces have different quantization index a smooth
+ * quantization curve is used to get a smooth overlap between the different
+ * pieces.
+ * To get to the transformdomain Cook uses a modulated lapped transform.
+ * The transform domain has 50 subbands with 20 elements each. This
+ * means only a maximum of 50*20=1000 coefficients are used out of the 1024
+ * available.
