resampling audio with linear interpolation

https://www.mathworks.com/matlabcentral/answers/156604-resampling-audio-with-linear-interpolation

hi guys, i need your help, i made a program that reduce the sampling from 44100 to 8000 but i need that the audio has the same time with the resampling im aware that the audio its gonna sound different but thats the point the method that i have to use is linear interpolation i made this code that works with the resampling but the sound is weird :c someone help me …

To resample an audio waveform from one freqeuncy to another, you can use transforms.Resample or functional.resample . transforms.Resample precomputes and caches the kernel used for resampling, while functional.resample computes it on the fly, so using transforms.Resample will result in a speedup when resampling multiple waveforms using the …

audioresample resamples raw audio buffers to different sample rates using a configurable windowing function to enhance quality. By default, the resampler uses a reduced sinc table, with cubic interpolation filling in the gaps. This ensures that the table does not become too big. However, the interpolation increases the CPU usage considerably.

interpolation - How to Resample Audio Using FFT or DFT ...

https://dsp.stackexchange.com/questions/2962/how-to-resample-audio-using-fft-or-dft

The previous steps have to be done no matter how you want to resample the data. Now let's talk about how to do it with FFT's. The trick to resampling with FFT's is to pick FFT lengths that make everything work out nicely. That means picking an FFT length that is a multiple of the decimation rate (441, in this case).

resampling or interpolation? - Stack Overflow

https://stackoverflow.com/questions/17852639/resampling-or-interpolation

In the case of audio, these are the amplitude values sampled at each time point. Resampling is used to either increase the sample rate (make the image larger) or decrease it (make the image smaller). Interpolation is the process of calculating values between sample points. So, if you resample an image you can use interpolation to do it.

4.1.3 What is the “resampling factor”? The interpolation factor is simply the ratio of the output rate to the input rate. Given that the interpolation factor is L and the decimation factor is M, the resampling factor is L / M. In the above example, the resampling factor is 147 / 160 = 0.91875.
