SoX
---

This file contains information specific to the Win32 version of SoX.
Please refer to the README files for general information.

sox_ng.exe -- main EXE of SOX

wget.exe -- optional external program from "https://www.gnu.org/software/wget"
            used to fetch input files from the internet
	    instead of from local storage

ffmpeg.exe -- optional external program from "ffmpeg.org" used to decode
              dozens of audio (and video!) file formats not supported natively

All were compiled using the M Cross Environment MXE
See http://codeberg.org/sox_ng/sox_ng/wiki/Distro-MXE.md
and http://mxe.cc

The CMake files may or may not still work.

SoX Helper Applications
-----------------------

SoX also includes support for SOXI_NG.EXE, PLAY_NG.EXE and REC_NG.EXE and
their behaviors are documented in the included PDF's.  They have the same
install restrictions as SOX_NG.EXE.

SOXI_NG.EXE, PLAY_NG.EXE, and REC_NG.EXE are not distributed with this package
to reduce size requirements. They are, in fact, only copies of the original
SOX_NG.EXE binary which changes SOX_NG.EXE's behavior based on the
executable's filename.

If you wish to make use of these utils you can copy them or make
symbolic links to them:

    copy sox_ng.exe soxi_ng.exe
    copy sox_ng.exe play_ng.exe
    copy sox_ng.exe rec_ng.exe
or
    Powershell> new-item -ItemType SymbolicLink -Path .\play_ng.exe -Target .\sox_ng.exe
    CMD.EXE> mklink /D play_ng.exe sox_ng.exe (cmd.exe)

The play and record functionality can also be equated using the "-d" option
with SOX_NG.EXE. soxi_ng functionality can be equated using the "--info" option.
The rough syntax is:

play_ng: sox_ng [input files and options] -d [effects]
rec_ng:  sox_ng -d [output file and options] [effects]
soxi_ng: sox_ng --info [input files and options]

Building SoX_NG.EXE yourself
----------------------------

The sox_ng Windows executable is cross-compiled using MXE (http://mxe.cc)
and it's dead easy.

# Install the things it needs
sudo apt-get install \
    autoconf automake autopoint bash bison bzip2 flex g++ g++-multilib \
    gettext git gperf intltool libc6-dev-i386 libgdk-pixbuf2.0-dev \
    libltdl-dev libgl-dev libpcre3-dev libssl-dev libtool-bin \
    libxml-parser-perl lzip make openssl p7zip-full patch perl python3 \
    python3-distutils python3-mako python3-packaging python3-pkg-resources \
    python3-setuptools python-is-python3 ruby sed sqlite3 unzip wget xz-utils
# For other Unix distros, see https://mxe.cc#Requirements

# Get a copy of MXE
git clone https://github.com/mxe/mxe.git
cd mxe

# Fetch the configuration file for sox_ng
wget -P src https://codeberg.org/sox_ng/sox_ng/releases/download/sox_ng-14.6.0.1/sox_ng.mk

# Build it
make sox_ng

# Build the additional packages it can use
make wget ffmpeg

# Make the distribution zip file
zip -j sox_ng-win32.zip usr/i686-w64-mingw32.static/bin/{sox_ng,wget,ffmpeg}.exe

Appendix - wget, curl and ffmpeg Support
----------------------------------------

The SoX Windows binary can make use of the wget or curl command line utility
to load files over the internet or listen to shoutcast streams.
A configure option --with-curl says to prefer curl over wget
if both are available.

It can also use the ffmpeg utility to read four dozen more audio (and video!)
formats.

Binary copies of wget and ffmpeg are available on the sox_ng Releases page.

For SoX to make use of wget, curl or ffmpeg, they must be located either
in your PATH or in the same directory that SoX is run from and
custom configuration of wget can be made by editing the file wget.ini
contained in the same directory as wget.exe.

Appendix - MP3 and AMR-NB/AMR-WB Support
----------------------------------------

Now that the MP3 patents have expired and the opencore AMR libraries
are free, SoX contains support for reading and writing these files.

Appendix - LADSPA Plugins
-------------------------

SoX has built-in support for LADSPA Plugins; see http://www.ladspa.org

SoX will search for these plugins based on the LADSPA_PATH
environment variable.  See sox_ng.txt for further information.
