About

WavPack is a completely open audio compression format providing

lossless, high-quality lossy, and a unique hybrid compression mode.

For version 5.0.0, several new file formats and lossless DSD audio

compression were added, making WavPack a universal audio archiving

solution.

In the default lossless mode WavPack acts just like a WinZip

compressor for audio files. However, unlike MP3 or WMA encoding which

can affect the sound quality, not a single bit of the original

information is lost, so there's no chance of degradation. This makes

lossless mode ideal for archiving audio material or any other

situation where quality is paramount. The compression ratio depends on

the source material, but generally is between 30% and 70%.

The hybrid mode provides all the advantages of lossless compression

with an additional bonus. Instead of creating a single file, this mode

creates both a relatively small, high-quality lossy file that can be

used all by itself, and a "correction" file that (when combined with

the lossy file) provides full lossless restoration. For some users

this means never having to choose between lossless and lossy

compression!

WavPack employs only well known, public domain techniques (i.e.,

linear prediction with LMS adaptation, Elias and Golomb codes) in its

implementation. Methods and algorithms that have ever been patented

(e.g., arithmetic coding, LZW compression) are specifically avoided.

This ensures that WavPack encoders and decoders will remain open and

royalty-free.

Features

WavPack 5.3.0 features include:

* Compatible with virtually all audio data formats including 8, 16,

24, and 32-bit integer PCM; 32-bit float PCM; DSD audio; mono, stereo,

and multichannel; sampling rates from 6 to 192 kHz (and non-standard

rates)

* Handles all modern audio file formats including Microsoft

WAV/BWF/RF64, Sony Wave64, Apple CAF, Philips DSDIFF, and Sony DSF

(all with no size limitations)

* Multiplatform support including Windows, Linux, and OS X, plus a

Flash decoder and encoder

and a Silverlight decoder

that can work virtually anywhere, and now

a web-based audio converter that can decode WavPack

files online

* DirectShow filters for Windows, plus full Unicode support on the

Windows command-line

* Easily transcode from WavPack to WavPack with a single command

(including tag copy)

* Hybrid mode operates as low as 2.25 bits/sample (or 196 kbps for

CD audio)

* Dynamic noise shaping (dns) for optimum quality at lower hybrid

bitrates

* Free and open source with easy to use C library API and

unrestrictive license (BSD)

* Intuitive command line interface (with wildcards and destination

directory)

WavPack has been tested and works well with the following quality

Windows software:

* CUSTOM WINDOWS FRONTEND (by Speek)

* DIRECTSHOW FILTER to allow WavPack playback in WMP, MPC, etc.

* WMP TAG PLUS allows WMP 11+ to read and write WavPack file tags

* CHECKWAVPACKFILES to batch verify WavPack files/folders (by

gl.tter)

Hardware

Yes! Hardware support for WavPack is starting to appear:

* ROCKBOX is an open-source replacement firmware that runs on many

past and current model portable music players including many APPLE

IPOD models; the COWON IAUDIO X5, X5V, X5L, M5, M5L, M3 AND M3L

models; the IRIVER H100, H300 AND H10 series; the OLYMPUS M:ROBE 100;

the SANDISK SANSA C200, E200 AND E200R series (and the FUZE

unofficially); and the TOSHIBA GIGABEAT X AND F series. With Rockbox

installed on these players you can play all current WavPack files in

all modes (although the _very high_ mode is not recommended) and

models that allow it can even record to lossless WavPack! My favorite

supported player is the IRIVER H120 which has the unique feature of

optical SPDIF I/O which I use to record from an HD radio for 10 hours

straight on a single charge! Click on the banner below to go to the

Rockbox site:

* Cowon was the first company to offer a PMP with native support for

WavPack. It was the A3, and Cowon followed that up with the O2PMP.

These models have both been discontinued, but currently all of the

high-end COWON PLENUE models (except the low-cost D) support WavPack

playback, like this gorgeous gold Plenue 1 (pic

). Click the banner to see more about the Plenue

1, which was selected by CNET.com as the best MP3 player of 2017:

* Another high-end portable music player that supports WavPack is

the Luxury & Precision L5 PRO. This is another great looking player

(pic ) than even comes with a leather case (pic

). The L5 PRO also plays DSD files

(although not WavPack DSD files yet) and has an S/PDIF optical output.

Click the banner below to see more about the L5 PRO:

* Moving into the home, Dune HD makes a complete line of media

players including the high-end Duo 4K (pic

) and several less expensive, but fully

functional, media players. I have not tried any of these because

they're not commonly sold in the US, but they all claim to have

WavPack support. Hopefully they are available in your country...click

the banner to find out!
