这是这个系列的第一篇,介绍在国内几乎不为人知却特点鲜明的Amplitude——app用户行为分析与用户增长分析工具。 你可能没有听说过Amplitude,但你可能听说过Mixpanel(没有听说过的朋友也没关系,不久的未来我们会有一个专门的文章介绍这家同样很牛的公司),没错,Amplitude是Mixpanel的有力挑战者 在美国,很多用户因为种种原因(后面会说到),从Mixpanel转投到了Amplitude。 公司简介 Amplitude是这家公司的名字,也是产品的名字。 Amplitude可以说是一个很聚焦的产品。 ? 这是这个工具的旧界面 ? 这是这个工具的新界面 下图是Amplitude的用户留存Cohort分析的界面。 ? ,这些附加功能虽然Amplitude没有直接包含,但他们宣称可以通过与第三方的无缝整合获得。

Control: Easy to adjust amplitude and period by changing constants. Customizing the Pattern You can easily change the period and amplitude of the zigzag by introducing variables : functionzigzag(t, period = 4, amplitude = 1) { return amplitude * (Math.abs((t % period) - period / period / 4) / (period / 4); } period controls how many time units it takes to complete a full cycle. amplitude adjusting constants or wrapping this into a reusable function, you can easily customize period and amplitude

其中最核心、也最易混淆的,便是音高(Pitch) 与音量(Loudness),以及构成音量感知的三个层次——振幅(Amplitude)、均方根值(RMS)与响度(Loudness)。 它关乎声音的强弱,但这一感知背后,其实有三层递进的概念:最原始的振幅(Amplitude)、统计意义上的均方根值(Root Mean Square, RMS),以及最终主观的响度(Loudness)。 它包含三个层次:第一层:振幅(Amplitude)- 声音的“瞬时身高”振幅描述的是声波在某一瞬间偏离静默状态的距离。它是声音最原始的物理形态,直接对应音频文件中的采样值(Sample Value)。 三、 概念辨析与应用场景概念本质关键特点典型应用振幅(Amplitude)客观物理量瞬时值,波动快,有正负防止录音削波(Clipping),绘制波形图(Waveform)均方根值(RMS)客观统计量短期平均能量 音高(Pitch) 定义了声音的本体,而音量的旅程则从原始的振幅(Amplitude) 出发,经均方根值(RMS) 进行能量平均,最终在响度(Loudness) 层面抵达我们的内心。
