fulldecent/FDWaveformView

This system is an iOS and visionOS library for rendering audio waveforms, designed to integrate into Swift applications. It provides asynchronous waveform visualization that separates audio data loading from rendering to maintain UI responsiveness. The library supports various audio formats and offers configurable display modes, including linear and logarithmic scaling, along with interactive controls for scrubbing and zooming.

The Example/Sources directory now includes a complete SwiftUI application that demonstrates the FDWaveformView library. This example provides a user interface for loading audio files (specifically AIFF in this instance), scrubbing, stretching, and scrolling through the waveform, adjusting zoom levels, and switching between linear and logarithmic waveform rendering modes. It also includes performance profiling capabilities to measure rendering and loading times, along with controls to randomize waveform and background colors.

Example/Sources · high confidence

The Example directory now includes a complete Xcode project (Example.xcodeproj) that serves as a demonstration application. This app integrates the FDWaveformView framework to visualize audio waveforms and includes sample audio assets (MP3, M4A, OGG, AIFF) for testing. The project is configured with Swift 5.3 compatibility and standard iOS build settings, providing a concrete reference for integrating the library into an iOS application.

Example/Example.xcodeproj · high confidence

The library has been refactored to separate audio data loading from rendering via a new \FDWaveformDataSource\ protocol and its \FDWaveformAudioDataSource\ implementation. This change makes the waveform view asynchronous, allowing audio assets to be loaded and processed in the background without blocking the main thread. Users will experience smoother UI interactions as waveform generation no longer freezes the interface, and the system now correctly aligns the rendering timescale with the audio's actual sample rate for accurate playback synchronization.

Sources · high confidence

Added a new test suite for the FDWaveformView component that verifies its initialization state, property setters and getters (including scrubbing, stretching, scrolling, and color configurations), and WaveformType enum equality.

Tests · high confidence

The project now includes a Package.swift manifest, enabling installation via Swift Package Manager. The package targets iOS 15 and visionOS 1, providing the FDWaveformView library and its associated test suite.
