Abstract
A method of analysing an audio signal is disclosed. A digital representation of an audio signal is received and a first output function is generated based on a response of a physiological model to the digital representation. At least one property of the first output function may be determined. One or more values are determined for use in analysing the audio signal, based on the determined property of the first output function.
Claims13
A method of analysing an audio signal, the method comprising the steps of:
- (a) receiving a digital representation of an audio signal;
- (b) generating a first output function based on a response of a physiological model to the digital representation;
- (c) determining at least one property of the first output function;
- and
- (d) determining one or more values for use in analysing the audio signal, based on the determined property of the first output function.
An apparatus for analysing an audio signal, the apparatus comprising:
- means for receiving a digital representation of an audio signal;
- means for generating a first output function based on a response of a physiological model to the digital representation;
- means for determining at least one property of the first output function;
- and means for determining one or more values for use in analysing the audio signal, based on the determined property of the first output function.
A system for analysing an audio signal, the system comprising:
- a memory comprising data and a computer program;
- a processor coupled to the memory for executing the computer program, the computer program comprising instructions for:
- (a) receiving a digital representation of an audio signal;
- (b) generating a first output function based on a response of a physiological model to the digital representation;
- (c) determining at least one property of the first output function;
- and
- (d) determining one or more values for use in analysing the audio signal, based on the determined property of the first output function.
