https://stackoverflow.com/questions/4009737/library-for-audio-resampling
The resample software package contains free sampling-rate conversion and filter design utilities written in C. Older Version for NeXT Computers. Original 1983+ source for the PDP KL-10. Erik de Castro Lopo's "SecretRabbitCode" libsamplerate libresample based on `resample-1.7P libresample4j is a Java port of libresample.

This resampler uses cubic. interpolation instead of linear interpolation in the above paper. This. makes the table much smaller and makes it possible to compute that table. on a per-stream basis. In turn, being able to tweak the table for each. stream makes it possible to both reduce complexity on simple ratios.
