GitHub - djeedai/libfar: C/C++ fast audio resampling library
https://github.com/djeedai/libfar
libfar. Fast audio resampling library for C and C++. This library focuses on speed at the expense of audio quality, for scenarios where correct audio processing is not needed. For that it takes many shortcuts to reduce processing and latency.

The spectrograms below show the frequency representation of the signal, where the x-axis corresponds to the frequency of the original waveform (in log scale), y-axis the frequency of the plotted waveform, and color intensity the amplitude. sample_rate = 48000 resample_rate = 32000 waveform = get_sine_sweep(sample_rate) plot_sweep(waveform, sample_rate, title="Original …
Free Resampling Software - Stanford University
https://ccrma.stanford.edu/~jos/resample/Free_Resampling_Software.html
The free Open Source Audio Library Project (OSALP) contains a C++ class based on resample. The Speex speech coder/decoder (based on CELP) contains a variation of the resample algorithm in the file resample.c , is free and open-source , and is released under a BSD-style license ( i.e. , free for both commercial and noncommercial uses).

Upsampling C code | AVS Forum
https://www.avsforum.com/threads/upsampling-c-code.2127874/
I had thought writing C code for upsampling from 8kHz to 16 kHz is easy. Just insert zeros between the samples. So, I wrote: for(i=buffer_size/2 - 1; i >= 0; i--) {buffer[i*2] = buffer; buffer[i*2 + 1] = 0;} where half of buffer has samples belonging to 8kHz, rest of buffer is empty, and full buffer would hold 16kHz samples at the end of loop. Am I right?

How to Resample Audio with NAudio - Sound Code
https://www.markheath.net/post/how-to-resample-audio-with-naudio
Or if you’re playing audio through an API like WASAPI, which doesn’t resample for you, you need to do this yourself (actually WasapiOut in NAudio does include a resampling step on your behalf if needed). There are also some gotchas you need to be aware of when resampling. In particular there is the danger of “aliasing”.
Fully Managed Input Driven Resampling with NAudio in C#
https://www.markheath.net/post/fully-managed-input-driven-resampling-wdl
So that’s how you can perform input driven resampling in fully managed C#. Admittedly it is a little more cumbersome than the equivalent output driven code: int outRate = 16000 ; var inFile = @"E:\some input file.mp3" ; var outFile = @"E:\resampled wdl.wav" ; using ( var reader = new AudioFileReader (inFile)) { var resampler = new WdlResamplingSampleProvider (reader, …
