    Abstract: PROBLEM TO BE SOLVED: To decide at least one encoding related parameter which is suitable for the optimum encoding of a specified type of audio material by analyzing the audio track of the specified type of audio material or another part. SOLUTION: When the given part of the specified type of audio material is encoded for transmission in the perceptual audio coder of a communication system, the value of an encoding related parameter is identified and, then, it is utilized with the encoding of the given part. The decided value of the encoding related parameter can be at least a part of an acoustic and psychological model which is utilized for the purpose of encoding the given part of the specified type of audio material in the perceptual audio coder. In another example, the value of the encoding related parameter can be the setting of an audio processor to be utilized for the purpose of processing the given part of the specified type of audio material before encoding the given part in the perceptual audio coder.

    Abstract: Audio tracks or other portions of a particular type of audio material to be encoded are analyzed to determine a value of at least one coding-related parameter suitable for providing optimal encoding of the particular type of audio material. When a given portion of the audio material is to be encoded for transmission in a perceptual audio coder of a communication system, the value of the coding-related parameter is identified and then utilized in conjunction with the encoding of the given portion. The determined value of the coding-related parameter may be at least a portion of a psychoacoustic model utilized in encoding the given portion of the particular type of audio material in the perceptual audio coder. As another example, the value of the coding-related parameter may be a setting of an audio processor utilized to process the given portion of the particular type of audio material prior to encoding the given portion in the perceptual audio coder.
