lossyWAV 1.4.3e

lossyWAV is a useful command-line tool designed to process audio files and significantly reduce their size without a noticeable loss in quality.

By applying an intelligent noise shaping algorithm, it trims excess data from the audio signal, making it more efficient for storage and streaming.

This software is especially beneficial for users looking to optimize their music library or audio archives.

The output can be processed using different lossless codecs such as WavPack, FLAC, LPAC, Tak, WMA-Lossless or MPEG-4 ALS, thus ensuring a small size of resulting files.

The primary advantage of lossyWAV is its ability to maintain high audio fidelity while producing much smaller file sizes compared to lossless formats.

It can be particularly handy for audiophiles and music enthusiasts who have extensive collections and need to save on disk space without compromising on sound quality.

Using lossyWAV involves working through the command-line interface (CLI), which might be a new experience for some users.

However, the documentation and community support available can help guide you through the process of setting it up and using it effectively. This approach ensures that the tool remains lightweight and efficient, focusing on its core functionality without unnecessary graphical overhead.

Efficient Audio Compression with lossyWAV


This compact audio processor is available in the x86 and x64 versions and it manages to improve the compression ratio for lossless codecs significantly.

lossyWAV uses a libfftw3-3.dll (32 and 64 bit) library. Place it in the same folder as lossyWAV.exe and the FFT analysis will be accelerated.

The latest version of lossyWAV underwent the following changes:


- Modification to "-l, --limit" parameter. The upper bound for the upper calculation limit is now 45.35% of the sample-rate of audio processed. Entering a value that exceeds this will no longer give an error, however the selected limit will be reduced to the upper bound for the upper calculation limit appropriate to the sample-rate of the audio being processed. The lower bound for the upper calculation limit remains at 12.5kHz.
- Introduction of a "hybrid" adaptive noise shaping "-s h, --shaping hybrid" that takes into account the results of all analyses performed and not just those for c.1.5ms and c.20ms.
- etc.



Whether you are compressing files for personal use or preparing audio for professional projects, lossyWAV provides a robust solution for high-quality audio compression.
