When using mfcc, the `window` parameter can use `numpy.hamming`, but `numpy.hamming` is a funtion, and it can take an `int` input as number of points in the output window.
See [numpy.hamming Doc](ht…

**MFCCs** are commonly derived as follows:
- Take the Fourier transform of (a windowed excerpt of) a signal.
- Map the powers of the spectrum obtained above onto the mel scale, using triangular …

Im trying to extract mfcc features from audio of a video file.
I tried FFMPEG:
```
def extractAudioFromVideo(video, audio_out="out.wav"):
cmd="ffmpeg -i {} -acodec pcm_s16le -ac 1 -ar 16000 {…

發現
- tri1前還有個mono
- 由 train_mono.sh 伴 train_cmd即run.pl, data/train, data/lang_train 輸出至 exp/mono
- mono align_si, train_deltas 產生 tri1接著tri2 tri3 tri4
- 看都有tri5 前面exit0
- STAGE 16的 train_cle…

Right now, we only have Hann window in there, but we could add all of the scipy window functions.
Side note: the value currently recorded is half width half max. Would it be clearer to change this to…
