## What it is
A Swift library that generates waveform images from audio files on iOS, iPadOS, macOS, visionOS, and Mac Catalyst. It provides native SwiftUI and UIKit views plus a raw API for rendering waveforms to UIImage/NSImage or extracting normalized audio samples.

## Use cases
- render waveform images from audio files in swift
- show audio waveform in swiftui view
- display live waveform while recording on ios
- extract amplitude samples from an audio file
- draw circular or stereo waveforms in an ios app

## When to choose
- you need native Apple-platform waveform rendering with SwiftUI or UIKit views
- you want customizable waveform styles and renderers (linear, circular, stereo)
- you need both image rendering and raw sample analysis

## When to avoid
- you need waveform rendering on non-Apple platforms
- you need full audio playback or editing, not just visualization
- you need cross-platform (Android/web) audio visualization

## Facets
- artifact type: library
- maturity: active
- function: audio-processing, image-processing, ui-components
- domain: mobile-development, desktop-applications, graphics
- platform: cross-platform
- tags: swiftui, uikit, waveform, fft, visionos, mac-catalyst, audio-visualization, audio, ios, macos, swift
