—Compilation of musical instrument sample s requires careful elimination of badly recorded samples and validation of sample classification into correct categories. This paper introduces algorithms for automatic removal of bad instrument samples using Automatic Musical Instrument Recognition and Outlier Detection techniques.

基于FCM的改进遗传算法步骤以及程序，内容清晰，过程详细而明确，结果清楚，很不错。(FCM based on improved genetic algorithm steps, and procedures, clarity, detail and clear process, the results clearly, very good.)

SPECTRAL_ANALYSIS M-file for spectral_analysis.fig SPECTRAL_ANALYSIS, by itself, creates a new SPECTRAL_ANALYSIS or raises the existing singleton*. H = SPECTRAL_ANALYSIS returns the handle to a new SPECTRAL_ANALYSIS or the handle to the existing singleton*. SPECTRAL_ANALYSIS( CALLBACK ,hObject,eventData,handles,...) calls the local function named CALLBACK in SPECTRAL_ANALYSIS.M with the given input arguments. SPECTRAL_ANALYSIS( Property , Value ,...) creates a new SPECTRAL_ANALYSIS or raises the existing singleton*. Starting from the left, property value pairs are applied to the GUI before spectral_analysis_OpeningFcn gets called. An unrecognized property name or invalid value makes property application stop. All inputs are passed to spectral_analysis_OpeningFcn via varargin.
