lossyWAV 1.4.3i is a free command-line audio compression tool that intelligently reduces audio file sizes by up to 45% without audible quality loss.

Perfect for audiophiles and music enthusiasts who need to save disk space while maintaining pristine sound quality.

What lossyWAV Does for You

This powerful audio processor applies smart noise shaping algorithms to trim excess data from your audio files.

The result? Smaller file sizes when used with lossless codecs like WavPack, FLAC, LPAC, TAK, WMA Lossless, or MPEG-4 ALS - without compromising the audio fidelity you demand.

Latest Version Features (1.4.3i)

The newest version includes significant improvements:

• Enhanced Auto-Feedback: For low quality preset range (-10.0 ≤ quality < -5.0), auto-feedback now defaults to 3.0 with optimized rounding noise (1.75) and shaping noise (0.5) parameters.
• Smart Bit Removal: The process now detects consecutive added clips of the same sign and reduces bit removal accordingly.
• Streamlined Interface: Removed the "spread" numeric sub-parameter from weighted shaping method for simpler operation.
• Improved Limit Handling: The "--limit" parameter caps calculations at 45.35% of audio sample rate with automatic adjustment.
• New Hybrid Mode: Adaptive noise shaping mode integrates all analyses for superior performance.
  
  Important: This executable is 64-bit only.

Recommended Usage

For optimal results, scale your input by 0.25 to losslessly shift samples "down" by two bits.

This is especially recommended when using weighted shaping, as it gives the noise shaping method necessary headroom and typically produces lower bitrates overall.

System Requirements

• Platform: Windows (64-bit only).
• Optional Enhancement: Place libfftw3-3.dll (64-bit) in the same folder as lossyWAV.exe for accelerated FFT analysis.
• Interface: Command-line interface (CLI) - lightweight and efficient.

Why Choose lossyWAV?

• Space Savings: Reduce lossless file sizes significantly without quality loss.
• Format Flexibility: Works with all major lossless codecs.
• Professional Grade: Trusted by audio professionals and enthusiasts worldwide.
• Free & Open: No cost, no restrictions.
