In dejavu/dejavu/init.py, line 202
nseconds = round(float(offset) / DEFAULT_FS DEFAULT_WINDOW_SIZE DEFAULT_OVERLAP_RATIO, 5)
I believe that the code above should be ... (1 - DEFAULT_OVERLAP_RATIO) ...
for DEFAULT_WINDOW_SIZE DEFAULT_OVERLAP_RATIO gets Overlap Length
and DEFAULT_WINDOW_SIZE (1 - DEFAULT_OVERLAP_RATIO) gets Hop Length
It won't casue any problem if DEFAULT_OVERLAP_RATIO is set to 0.5, however, I changed it to another value and it returns wrong offset seconds.
dejavu/dejavu/init.py, 第202行是否应该修正为... (1 - DEFAULT_OVERLAP_RATIO) ...
因为DEFAULT_WINDOW_SIZE DEFAULT_OVERLAP_RATIO计算的是STFT中重叠部分的长度
而DEFAULT_WINDOW_SIZE (1 - DEFAULT_OVERLAP_RATIO)才是一跳的长度
因为DEFAULT_OVERLAP_RATIO的默认值是0.5，所以一般不会造成任何问题，但是当DEFAULT_OVERLAP_RATIO被设置为其他值时，会导致返回的偏移秒数有误
