I have a Audiofile "03 Black Smoke.wav", this Audiofile i have to downsample to 500 Hz. After that, i have to cut the Audiofile to the max length of 3 min. Ist the code doing the downsampling correctly? And can someone give me a hint, how i could extract the envelope from the input_cut.wav File for each sample point? % Downsampling of the audio ...
audio - Downsampling in MATLAB - why scaling filter ...
https://dsp.stackexchange.com/questions/47950/downsampling-in-matlab-why-scaling-filter-coefficients
This is the part where (downsampling) filter coefficients are calculated: fc = 1/2/pqmax; L = 2*N*pqmax + 1; h = firls ( L-1, [0 2*fc 2*fc 1], [1 1 0 0]).*kaiser (L,bta)' ; h = p*h/sum (h); (In this case pqmax and p both represent downsampling ratio.) Not sure what is the purpose of last line where all filter coefficients are scaled by downsampling ratio over coeffs sum, …

Downsampling consists of running the data through a low-pass filter followed by discarding samples, while upsampling consists of inserting samples then running the data through a low pass filter (also known as a reconstruction filter or interpolating filter). Aliasing occurs when the filtering steps are skipped or poorly done.

The signal is the labels for a dataset, and it needs to be downsampled because the features for the dataset was calculated using a running window. (So if the original dataset had 500 labels, the feature matrix has only 10 rows. I was told to train by downsampling the given labels; then, I need up upsample the predictions back up to 500.) $\endgroup$
