python - Downsampling wav audio file - Stack Overflow
https://stackoverflow.com/questions/30619740/downsampling-wav-audio-file
I have to downsample a wav file from 44100Hz to 16000Hz without using any external Python libraries, so preferably wave and/or audioop.I tried just changing the wav files framerate to 16000 by using setframerate function but that just slows down the entire recording. How can I just downsample the audio file to 16kHz and maintain the same length of the audio?

Here is an example of how to downsample an audio file called sound.wav to 16kHz (that’s the rate 16k) and also to reduce to a 16 bit recording (that’s the -b 16 ), to an output file named sound-down.wav: sox sound.wav -b 16 sound-down.wav rate 16k. Some more on sox’s resampling algorithm here. ← Quick and easy calories. Some resources ...
Q. What’s the best way to downsample? - Sound on Sound

I have no problem understanding dithering 24-bit audio to 16-bit, but am less clear about downsampling. Before attempting to master (once the mix is done and in stereo format) I take the file and downsample from 96kHz to 44.1kHz, but there is a definitely noticeable degrading of the high end when I’ve done this.

Can someone suggest the correct way to downsample please? I’m guessing someone must have solved this but couldn’t find anything conclusive on the forums. This is my workflow: pretrained model is 0.5.0; extract audio files from the video file using ffmpeg. ffmpeg -i original.avi -ab 160k -ac 1 -ar 16000 -vn audio.wav. The clips are at 44 ...

Going back to the previous example of ‘gong’ audio vector loaded in the Matlab variable space, the downsampling operation can be coded as follows. >>M=2 % downsample by 2 >>y_down = y (1:M:end); % keep every M-th sample. Note: Downsampling↗ is not same as decimation. Decimation↗ implies reducing the sampling rate of a signal by applying ...

Hence, when downsampling a 192 kHz audio, the target sampling rate should be 96 kHz (2:1 decimation) or 48 kHz (4:1 decimation). When downsampling a 176 kHz (176.4 kHz, actually) audio, the target sampling rate should be 88.2 kHz or 44.1 kHz (2:1 and 4:1 decimation, respectively). # Downsample with SoX
