Class SHSignature

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class SHSignature
extends NSObject
implements NSSecureCoding, NSCopying
    The @c SHSignature class is an opaque data container that can be used to store recognition data. Signatures are a compact lossy representation of the original audio. The original audio cannot be recreated from a Signature, there exists only enough data to confirm that the signature matches a certain piece of audio when it is also converted into a Signature. It is similar in utility to a hashing function. Signatures can be matched against any type of audio not just music. The only requirement for a match is that the reference and query Signatures both contain the exact same pre recorded audio e.g. a live rendition of a song will not match against a studio recorded performance of the same piece. There are exceptions to the requirement for exactly matching audio, a signature is robust against slight changes in frequency and speed. [@note] @c SHSignature is not intended to be subclassed API-Since: 15.0
