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 $M-1$ samples (i.e, keep every -th sample. For example, if is a vector of input samples, downsampling by implies

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.

Show activity on this post. I have a question to the Code below, because i'm not sure if i programmed everything right and that the Code really does what i want him to do. 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.

Downsampling - Aliasing - MATLAB & Simulink
https://www.mathworks.com/help/signal/ug/downsampling-aliasing.html
Downsample the signal by a factor of 2 and plot the spectrum of the original and downsampled signals. The downsampled signal is full band. The spectrum of the downsampled signal is a stretched and scaled version of the original spectrum, but the shape is preserved because the spectral copies do not overlap. There is no aliasing.

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.
