Feb, 2018
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
