上傳音訊檔案(*.wav)，調整參數並顯示其時域波形圖和時頻圖
Upload audio wav file, then show its samples and spectrogram.

Step 1, Upload Audio file

Only support *.wav

Step 2, Parameters

Select these for the spectrogram.

FrameSize (Number of samples): 256 512 1024 2048
Overlap (Number of samples): 128 256 512 1024
FFT length (Number of samples): 256 512 1024 2048

Must follow [ Overlap < FrameSize <= FFT length ]
Recommend (When sampling rate = 8k)
FrameSize: 256, Overlap: 128, FFT length: 512
Recommend (When sampling rate = 16k)
FrameSize: 512, Overlap: 256, FFT length: 1024
