Vehicle Sounds and Recognition

1978
The acoustic waveform that is of interest in the processing described in this chapter is obtained by recording the noise from a vehicle under normal operating conditions; it is a complex signal in which the characteristics of the engine, the exhaust system, the bodywork, and the environment are all intermingled.

Musical sound recognition

2009
In this paper, two different methods to implement one particular aspect of music transcription – musical note recognition – are presented. Both methods make use of existing algorithms in the form of the Constant-Q Transform (CQT) and the Discrete Wavelet Transform (DWT). Each existing algorithm is modified or extended so that a musical note recognition

Musical Sound Recognition by Active Learning PNN

2006
In this work an active learning PNN was used to recognize instru-mental sounds. LPC and MFCC coefficients with different orders were used as features. The best analysis orders were found by using passive PNNs and these sets were used with active learning PNNs. By realizing some experiments, it was shown that the entire performance was improved by using

System and method for sound recognition

The Journal of the Acoustical Society of America, 1986
Sounds produced by human or mechanical sources are recognized by comparison of certain waveform characteristic ratios with prestored ratios. Transitions and transition glides of characteristics are used to select certain stored groups of ratios for comparing.
