## Overview

`volume` is a command-line WAV volume scaler. The user supplies input and output paths plus a scaling factor; the program copies the 44-byte WAV header, scales each subsequent 16-bit sample, and writes the result. The repository is a tiny single-file utility, so its runtime behavior is represented without artificial subsystem groups.

Main entry points: [`volume.c`](https://github.com/sanishpoudel/volume/blob/main/volume.c) (Volume program)
