这篇博客主要介绍了在使用pyAudioAnalysis库时遇到的三个TypeError错误：mfccInitFilterBanks函数传参过多、浮点数不能作为整数解释、numpy浮点数无法用作索引。解决方案包括删除多余参数、将浮点数转换为整数以及类型转换。

1. TypeError: mfccInitFilterBanks() takes 2 positional arguments but 7 were given

The issue

In the function stFeatureSpeed()from audioFeatureExtraction.py make a call: [fbank, freqs] = mfccInitFilterBanks(Fs, nfft, lowfreq, linsc, logsc, nlinfil, nlogfil), but this function is only able to receive two arguments. It has the following signature: def mfccInitFilterBanks(fs, nfft)

The "extra" arguments are: lowfreq, linsc, logsc, nlinfil, nlogfil

These are all defined in the mfccInitFilterBanks function itself wit exactly the same values.

Note that there is a comment in the source code (audioFeatureExtraction.py) that says that the stFeatureSpeed() function is work in progress. so there could be many (non obvious) bug
