TLDR
In this article, the authors proposed a method for recognizing audio samples that locates an audio file that most closely matches the audio sample from a database indexing a large set of original recordings, where each indexed audio file is represented in the database index by a set of landmark timepoints and associated fingerprints.Abstract:
A method for recognizing an audio sample locates an audio file that most closely matches the audio sample from a database indexing a large set of original recordings. Each indexed audio file is represented in the database index by a set of landmark timepoints and associated fingerprints. Landmarks occur at reproducible locations within the file, while fingerprints represent features of the signal at or near the landmark timepoints. To perform recognition, landmarks and fingerprints are computed for the unknown sample and used to retrieve matching fingerprints from the database. For each file containing matching fingerprints, the landmarks are compared with landmarks of the sample at which the same fingerprints were computed. If a large number of corresponding landmarks are linearly related, i.e., if equivalent fingerprints of the sample and retrieved file have the same time evolution, then the file is identified with the sample. The method can be used for any type of sound or music, and is particularly effective for audio signals subject to linear and nonlinear distortion such as background noise, compression artifacts, or transmission dropouts. The sample can be identified in a time proportional to the logarithm of the number of entries in the database; given sufficient computational power, recognition can be performed in nearly real time as the sound is being sampled.read more

Method for user context recognition using sound signatures
TL;DR: In this paper, a method for user micro context recognition using sound signatures was proposed, which includes: recording an environment sound sample from a microphone into a mobile device by a trigger stimulus; simultaneous to recording a sound sample, collecting hardware and software macro context data from available mobile devices; extracting a sound signature from the recorded sound sample based on sound features and spectrograms; comparing for similar patterns the recorded signature with reference sound signatures stored in a sound database; updating the sound database, checking if the recorded sounds was recognized; performing a logical association between the sound label and the available

Content-based classification, search, and retrieval of audio
TL;DR: The audio analysis, search, and classification engine described here reduces sounds to perceptual and acoustical features, which lets users search or retrieve sounds by any one feature or a combination of them, by specifying previously learned classes based on these features.

Content-based retrieval of music and audio
TL;DR: In this article, a supervised vector quantizer is used to learn audio features from a corpus of simple sounds and musical excerpts, and the similarity measure is based on statistics derived from a supervised quantizer, rather than matching simple pitch or spectral characteristics.
