1. An apparatus implementing a method of obtaining a signature for audio data, the method comprising:
- receiving at the apparatus audio data to be analyzed;
determining at the apparatus a plurality of time domain features in said audio data;
selecting at the apparatus a subset of said time domain features according to their position in the order of the magnitude or strength of the respective features; and
generating at the apparatus a signature being descriptive, representative or characteristic for said audio data,wherein said signature is exclusively based on temporal positions of said subset of said time domain features.

Abstract
A method for analyzing audio data (AD) is provided wherein a signature (SAD) is generated based on a feature set (FS) comprising a plurality of time domain related features (TDFk). The signature (SAD) is formed in order to represent a plurality of temporal positions or ranges of a plurality of characteristics of time domain related features (TDFk) within said audio data (AD).

24. An apparatus implementing a method of analyzing audio data for obtaining a comparison result for the audio data, the method comprising:
-
receiving at the apparatus first audio data to be analyzed; determining at the apparatus a plurality of time domain features in said first audio data; selecting at the apparatus a subset of said time domain features according to their position in the order of the magnitude or strength of the respective features; and generating at the apparatus a signature being descriptive, representative or characteristic for said first audio data, wherein said signature is exclusively based on temporal positions or temporal ranges of said subset of said time domain features; providing at the apparatus a comparison signature, said comparison signature being descriptive, representative or characteristic for second audio data; and determining at the apparatus a comparison result based on comparing said signature with said comparison signature. - View Dependent Claims (25)
