    • Processor-implemented methods and systems for polyphonic note detection are disclosed. The method includes converting a portion of a polyphonic audio signal from a time domain to a frequency domain. The method includes detecting a fundamental frequency peak in the frequency domain. The method then detects a defined number of integer-interval harmonic partials. If a defined number of integer-interval harmonic partials relative to the fundamental frequency peak are detected the fundamental frequency is recorded as a detected note. This process is repeated for each fundamental frequency until each note in the polyphonic audio signal has been detected. For example, this method allows detection of each note in a strummed guitar chord to provide feedback on the tuning of each string in a strummed chord or allows detection and feedback of the timing and pitch errors for guitar chords played along with a reference track.
    • 公开了用于复音音符检测的处理器实现的方法和系统。 该方法包括将来自时域的多音音频信号的一部分转换为频域。 该方法包括检测频域中的基频峰值。 该方法然后检测定义数量的整数间隔谐波分量。 如果检测到相对于基频峰值的定义数量的整数间隔谐波部分,则将基频记录为检测到的音符。 对于每个基本频率重复该过程,直到已经检测到复音音频信号中的每个音符。 例如,该方法允许检测吉他弦中的每个音符,以提供对弦弦中的每个弦的调谐的反馈,或允许检测和反馈与参考轨道一起播放的吉他和弦的定时和俯仰误差。

    • A disposable contraceptive cervical barrier includes a bowl-shaped thin flexible member and a substantially thicker circular rim unitary with the flexible member. The rim provides a spring tension effect for helping to maintain the barrier in position. A plurality of cavities are formed in the rim and are equidistantly spaced therearound. The cavities are open so as to be capable of receiving and holding a quantity of a spermicide. Alternatively, the flexible member itself can be provided with a plurality of grooves for holding the spermicide. Preferably, the barrier is made from a mixture of a hydrophilic foam polymer and a more conventional polyurethane polyether prepolymer-catalyst system. The mixture is molded in a closed mold having a volume of about ten percent of the volume which the material would occupy if allowed to foam freely. The finished product is similar to an elastomer except that internally it has a dense cellular structure and is bounded by an impermeable skin.
    • 一次性避孕宫颈屏障包括碗形薄柔性构件和与柔性构件整体形成的基本上较厚的圆形边缘。 轮辋提供弹簧张力效果,有助于保持屏障的位置。 在轮辋中形成多个空腔,并在其周围等间距分布。 空腔是敞开的,以便能够接收和保持一定数量的杀精子剂。 或者,柔性构件本身可以设置有用于保持杀精剂的多个凹槽。 优选地,阻挡层由亲水性泡沫聚合物和更常规的聚氨酯聚醚预聚物 - 催化剂体系的混合物制成。 将该混合物模塑在一个封闭的模具中,该容器的体积大约为容纳泡沫的体积的10%。 成品类似于弹性体,只是内部具有致密的细胞结构并且被不透水的皮肤所限制。
