In signal processing, downsampling is the process of throwing away samples without applying any low-pass filtering. Mathematically, downsampling by a factor of implies, starting from the very first sample we throw away every $M …

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 ...
Decrease sample rate by integer factor - MATLAB …
https://www.mathworks.com/help/signal/ref/downsample.html
Description example y = downsample (x,n) decreases the sample rate of x by keeping the first sample and then every n th sample after the first. If x is a matrix, the function treats each column as a separate sequence. y = downsample (x,n,phase) specifies the number of samples by which to offset the downsampled sequence. Examples collapse all

Use the downsample () function in MATLAB to down-sample the audio signal by a factor of 2. Also reduce your sampling frequency (fs) by the same amount (fsnew=fs/2). Again use soundsc () to listen to this new undersampled audio signal. Repeat this downsampling process until the aliasing effect becomes very noticeable.

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.

https://dsp.stackexchange.com/questions/20303/trying-to-down-sample-audio
First you need to interpolate between samples rather than just retaining and discarding samples (which introduces horrible jitter noise during non-integer downsampling). Then, if the original audio data contained spectrum around or above 4000 Hz (half the sample rate), you will need to low-pass filter before or in conjunction with the ...
