Mel frecuency filterbank

If I put 300hz in low frequency parameter and 0hz in high frequency parameter. The high frequency parameter is samplerate/2=8000Hz (16kHz/2). So, it would be like in this photo, wouldn´t it?


Hi @Txomin,

That image has 10 filters and a low cutoff of 0 Hz.

If you are using the Edge Impulse defaults, then your filterbank would have 13 filters, a low cutoff of 300 Hz and a high cutoff of 8000 Hz (assuming your sample rate is 16kHz).
