WebNov 18, 2015 · So, for the 44100->8000 conversion, you'd insert 79 zeros between each neighbouring original samples to get to the sampling rate of 3528000. Then, you'd lowpass filter this signal to only preserve frequencies up to 4000 Hz. Then, you'd pick out every 441th sample and be done. Web1 Answer Sorted by: 1 Breaking down the conversion into an upsampling and a downsampling step as explained in mbaz's answer is not necessary - band-limited interpolation achieves the same result in one single process, for any conversion ratio, and its quality is easy to fine-tune (through various approximations of the band-limited pulse).
