Hi,
In the Edge Impulse’s page (Responding to your voice - Edge Impulse Documentation), in the MFCC block’s parameters, the low frequency is defined as 300, and the high frequency is defined as 0. How can the low frequency be higher than the high frequency?
So, if i put low frequency in 300 and high frequency in 0 (sample rate is 16kHz), the Mel filterbank is like in this photo??
The filterbank begins in 300Hz more o less, and it ends in 8000Hz.
