Looking for a Java developer to modify an example for reading and saving .wav files. Must have experience with .wav file handling. Clear example code provided.

This task requires a Java developer with specific experience in handling .wav audio files. The project involves modifying an existing Java example with rubberband library that currently processes a generated audio wave. The modification needed is for the example to read an actual .wav file, understanding its various attributes like sample rate, bit depth, and channels, and then save the processed audio back into a new .wav file. Clear and concise example code using the Rubberband library will be provided to guide the process. This project is ideal for someone who is proficient in Java and has experience with audio file manipulation, specifically .wav files. The code in Kotlin is appreciated.
