## What it is
FDWaveformView is a Swift UIView subclass that reads audio files and renders their waveforms with support for highlighting playback progress, zooming, and gesture-based scrubbing. It is distributed via Swift Package Manager and CocoaPods for iOS apps.

## Use cases
- display audio waveform in an iOS app
- add scrubbing to an audio player UI
- show playback progress on a waveform
- let users zoom into a waveform segment
- build a voice memo preview interface
- render waveforms from audio file URLs in Swift

## When to choose
- you need an iOS UIKit waveform view with built-in gestures
- you want progressive rendering and zoom for long audio files
- you prefer a lightweight MIT-licensed Swift component with SPM support

## When to avoid
- you need cross-platform (Android/web) waveform rendering
- you are building with SwiftUI only and want a native SwiftUI API
- you need audio playback itself, not just visualization
