本文探讨了音乐信号处理中的节奏与节拍跟踪方法，重点介绍了一种基于能量的起始检测方法。通过使用类似FIR滤波的时间窗口，文章详细阐述了从波形到新颖函数ΔEnergyLog的一系列数学技巧，包括对数变换等，以增强节拍位置的识别。
Tempo and Beat Tracking
if you are reading this paper .please do not go on !!! it's not for you.
methods:
1.Onset Detection
do something different
energy-base
use time window like fir filter!
look,do a little math trick we will get more!
(a) Waveform.
(b) Local
energy function.
(c) Discrete derivative.
(d) Novelty
function ΔEnergy obtained after half-wave rectification.
(e) Novelty function ΔEnergy Log
based on a logarithmic energy
function.
(f) Annotated note
onsets (the four beat positions
are marked by thick lines).
we clould use more math trick like log and so on .
