This is the README of lossyWAV for POSIX.
The README of lossyWAV (proper) was moved to README.lossyWAV.md.
This is an attempt to build lossyWAV natively in POSIX systems.
The Windows API is used in the official lossyWAV sources. But not extensively. lossyWAV is only offered as Windows binaries or source files which can't be compiled and linked to run in any non-Windows environment natively.
Luckily, I was able to replace the instances where the Windows API is used with C++11-compliant or POSIX-compliant code that provides similar functionality.
None of the changes would be enabled at the preprocessing stage if _WIN32 is
defined.
Tested platforms: GNU/Linux, OSX, FreeBSD, NetBSD, OpenBSD(needs latest eg++).
Building lossywav should be as simple as:
make

Usage : lossyWAV <input wav file> <options>
Example : lossyWAV musicfile.wav
Quality Options:
-q, --quality <t> where t is one of the following (default = standard):
I, insane highest quality output, suitable for transcoding;
E, extreme higher quality output, suitable for transcoding;
H, high high quality output, suitable for transcoding;
S, standard default quality output, considered to be transparent;
C, economic intermediate quality output, likely to be transparent;
P, portable good quality output for DAP use, may not be transparent;
X, extraportable lowest quality output, probably not transparent.
Standard Options:
-C, --correction write correction file for processed WAV file; default=off.
-f, --force forcibly over-write output file if it exists; default=off.
-h, --help display help.
-L, --longhelp display extended help.
-M, --merge merge existing lossy.wav and lwcdf.wav files.
-o, --outdir <t> destination directory for the output file(s).
-v, --version display the lossyWAV version number.
-w, --writetolog create (or add to) lossyWAV.log in the output directory.
Special thanks go to:
David Robinson for the publication of his lossyFLAC method, guidance, and
the motivation to implement his method as lossyWAV.
Horst Albrecht for ABX testing, valuable support in tuning the internal
presets, constructive criticism and all the feedback.
Sebastian Gesemann for the adaptive noise shaping method and the amount of
help received in implementing it and also for the basis of
the fixed noise shaping method.
Tyge Lovset for the C++ translation initiative.
Matteo Frigo and for libfftw3-3.dll contained in the FFTW distribution
Steven G Johnson (v3.2.1 or v3.2.2).
Mark G Beckett for the Delphi unit that provides an interface to the
(Univ. of Edinburgh) relevant fftw routines in libfftw3-3.dll.
Don Cross for the Complex-FFT algorithm originally used.
If you have a file hierachy containing your music stored in the FLAC format, you can use the following script in the directory of the library to convert the collection to LossyFLAC, at standard LossyWAV processing, and standard FLAC compression:
for i in **/*.flac; do
flac -d "$i" --stdout --silent|lossywav - --stdout --quality standard --stdinname -- |flac - -b 512 -o "${i%.*}.lossy.flac" --silent && metaflac --export-tags-to=- "$i" | metaflac --import-tags-from=- "${i%.*}.lossy.flac"
done
