Witryna30 paź 2024 · The steps for computing pitch using EMD-AMDF (Zong et al. 2013) is described in detail as follows: i. Use a bandpass filter to eliminate the signal having a frequency beyond the range 50–500 Hz. ii. Divide the speech into frames. iii. Make the voiced/unvoiced decision. iv. Compute the AMDF for voiced speech frame as given by WitrynaMost of pitch detection methods (e. g. based on autocorrelation function, AMDF) uses only information about frequencies of first peaks in harmonic series.

One thing I want to improve is early detection on or immediately before onsets. Sometimes, there’s a very short “glitch” when the pitch detector does not have a good estimate yet. It is barely perceptible and can just be taken as part of the attack.
