I have been looking at comparing using 8KHz vs 16KHz sampling rate for audio. It seems to be a pretty good bang for the buck for sound classification. I have the same audio, in 2 different projects that have the same configs. The only difference is the sample rate of the audio.
The weird thing is that the On-Device Performance predictions on the MFCC are greater for the 8KHz audio than the 16KHz. For 8KHz, the latency is 424ms and for 16KHz it is 352ms.
Are there some adjustments to the default parameters of MFCC that I should make when using 8KHz?
