Constant Q transform(CQ) ( CQT ) has advantages in pitch analysis of music signals, due to its exponentially spaced center frequencies. 由于采用指数分布的频域采样点,常数Q变换(CQ)(ConstantQTransform&CQT)在音乐信号的音调分析中有着独特的优点。
The Study of Multi-Dimension Music Melody Model Based on Constant Q Transform 基于CQT的多维音乐旋律模型的研究
The feature of subband energy distribution for ship-radiated noise is extracted by discrete wavelet transform, since wavelet analysis has constant Q. 以离散小波变换入手,利用小波分析的恒Q特性,提取了舰船噪声信号的子带能量分布特征。
