XSound 4.0.9

• Fix audio signal processing for pseudo stereo effector (Moreover, fix not to use AudioWorklet).
• Update packages

XSound 4.0.8

• AudioModule can use Time Stretch
  • Add parameter (speed) for Time Stretch to Pitch Shifter and AudioModule
• Fix Marshall (Preamplifier)
  • Add connection to pre Low-Pass Filter
  • Fix middle Low-Pass Filter cutoff frequency
  • Fix Post Equalizer Quality Factor
  • Fix comments (refactor)
• Shell (Bourne shell) script for build WebAssembly Modules
• Add eslint-plugin-jest-dom and ESLint config
• Update Node.js LTS version
• Update packages

XSound 4.0.7

• Use only the first element of FrozenArray
  • OverlapAddProcessor
    • PitchShifterProcessor
• Update packages

XSound 4.0.6

• Pitch Shifter uses WebAssembly Module that contains C function for Phase Vocoder
• Fix to generate window function and remove multiplying (The caller multiplies audio data by window function)
• Refactor
  • Use nullptr instead of NULL
    • NULL is macro, but nullptr is pointer type (std::nullptr_t). Therefore, using nullptr is safer than using NULL.
  • Remove constants.hpp
• Update Node.js LTS version
• Update packages

XSound 4.0.5

• OverlapAddProcessor enables to change render quantum size virtually. Therefore, processor that requires FFT/IFFT can improve frequency resolution as needed.
  • Enhance Noise Suppressor Quality
  • Enhance Vocal Canceler (on spectrum) Quality
  • Enhance Pitch Shifter Quality
• Add package @types/audioworklet and Delete @ts-expect-error comment
• Update packages

XSound 4.0.4

• Vocal Canceler
  • Add algorithm
    • Calculate left channel audio data and right channel audio data on spectrum domain
  • Fix to delete unnecessary loop every render quantum (every 128 samples) on time domain
• Refactor
  • Define Window functions to FFT.hpp
    • Window function is FFT pre-process
    • Prevent from including math.h duplicately
  • Fix format (main.ts)
• Update playground
  • Update vocal canceler parameters
• Update packages

XSound 4.0.3

• Window functions and Use window function before FFT
  • Rectangular Window (by default)
  • Hanning Window
  • Hamming Window
• Fix comment (Noise Gate)
• Update Node.js LTS version
• Update packages and Autofix (npm audit)

XSound 4.0.2

• Uses WebAssembly Module
  • Noise Gate
  • Vocal Canceler
  • FFT / IFFT utility function
    • Add mock for WebAssembly.instantiateStreaming method
• Refactor WebAssembly Modules
  • FFT / IFFT function for C++ header
    • Use const argument
    • Use size_t type
  • Header file defines buffer size
  • Use size_t instead of int
• webpack uses node:path module instead of path module
• Fix dockerignore files
• Update packages and Autofix (npm audit)

XSound 4.0.1

• Divide npm scripts for build multiple WebAssembly Modules into build single WebAssembly Module
• Update playground
  • Fix pitch shifter the default parameters on playground
• Format Jest config file
• Add .gitattributes
  • HTML, CSS and JavaScript files are linguist-vendored
• Update Node.js LTS version
  • webpack fixed to import package.json (Node.js v22 or later)
  • Update GitHub Actions
    • Support Node.js v22
    • Not support Node.js v18
• Update README
  • Update document URL
  • Add installation by pnpm
  • typo
• Autofix package-lock.json (npm audit fix)
