## Overview

Echoes is a Windows Forms audio player. The main workflow is selecting or opening audio, managing and filtering a playlist, then playing tracks with playback controls; the README also describes visualization, tag editing, hotkeys, equalization, statistics, duplicate finding, export/synchronization, and customization. Echoes.cs is the evident central UI and playlist module, but its excerpt is partial. Several feature modules are included based on the README and file tree; their internal wiring is not established by the sampled source.

Main entry points: [`Echoes.cs`](https://github.com/abraham-ny/echoes/blob/master/Echoes.cs) (Echoes player), [`Options.cs`](https://github.com/abraham-ny/echoes/blob/master/Options.cs) (Player options), [`Filter.cs`](https://github.com/abraham-ny/echoes/blob/master/Filter.cs) (Track filtering), [`Track.cs`](https://github.com/abraham-ny/echoes/blob/master/Track.cs) (Track model)
