AudioVisualizerKit

Provides the computational assistance for drawing the audio visualizer.

Requirements

• Development with Xcode 15.4+
• Written in Swift 5.10
• Compatible with iOS 17.0+, macOS 14.0+

Privacy Manifest

This library does not collect or track user information, so it does not include a PrivacyInfo.xcprivacy file.

Installation

AudioVisualizerKit is available through Swift Package Manager.

Xcode

1. File > Add Package Dependencies…
2. Search https://github.com/Kyome22/AudioVisualizerKit.git.
3. Add package and link AudioVisualizerKit to your application target.

CLI

1. Create Package.swift that describes dependencies.

   // swift-tools-version: 5.10
   import PackageDescription
   letpackage=Package(
   name:"SomeProduct",
   products:[.library(name:"SomeProduct", targets:["SomeProduct"])],
   dependencies:[.package(url:"https://github.com/Kyome22/AudioVisualizerKit.git", exact:"1.0.0")],
   targets:[.target(
   name:"SomeProduct",
   dependencies:[.product(name:"AudioVisualizerKit",package:"AudioVisualizerKit")])])

2. Run the following command in Terminal.

Usage

1. Get the URL of the music file.
2. Use AudioAnalyzer to play music and get magnitudes and RMS.
   • You can specify the FFT size.
   • You can specify a window function (hann or hamming or blackman).
3. Use AmplitudeSpectrumView to draw the audio visualizer.
   • You can select the shape type (straight or ring).
   • You can specify the drawing range.
   • Pass RMS to enable color linked to sound intensity.

import AudioVisualizerKit
import SwiftUI
structContentView:View{letaudioAnalyzer=AudioAnalyzer(fftSize:2048, windowType:.hannWindow)varbody:someView{AmplitudeSpectrumView(
shapeType:.straight,
magnitudes: audioAnalyzer.magnitudes,
range:0..<128,
rms: audioAnalyzer.rms
).padding().onAppear{leturl=Bundle.main.url(forResource:"example", withExtension:"mp3")!
try? audioAnalyzer.prepare(url: url)try? audioAnalyzer.play()}.onDisappear{
audioAnalyzer.stop()}}}
