I tried to write a re-sampling algorithm, which is not perfect yet. The current program is not applicable to all sampling rates. Currently, only the conversion between the 44.1khz and 48 kHz frequencies is supported. The preliminary results are satisfactory. Currently, only the spectrum and language spectrum are used as analysis tools. If you want to quantify the SNR and thd of the analysis, there is no suitable tool. You only need to wait for the company to use a professional audio analyzer.

 

A Conversion from 48 khz to 44.1khz was initially made, with no obvious quantization noise and no obvious harmonic. The waveform chart and the spectrum chart are as follows.

 

Currently, the source code is very imperfect. To avoid jokes, the code will not be published for the moment.
