Detailed Description

$ bin "Win64/r8bfreesrc"

Test/benchmarking utility.

This is an example file which you won't be able to compile as it includes some undisclosed program code. Please consider this example as a pseudo-code demonstrating the use of the library. Here you can find an example implementation of the simplest sample rate converter utility.
