How to compile SoX

In the download area you can find the .tar.gz archives of the source code used to compile the binaries available for download on this website:

  • sox.tar.gz this version has opus support disabled because it causes some problems on macOS and FreeBSD and is therefore compatible with all O.Ss.

IMPORTANT: the GitHub repository with updated source code and more information about this project is as always at mansr/sox

Linux

Every Linux distribution has its own package manager and its own packages, the following applies to Ubuntu but it can easily tweaked to work elsewhere. Install the dependencies first:

sudo apt-get install libopencore-amrnb-dev libopencore-amrwb-dev libao-dev libflac-dev libmp3lame-dev libtwolame-dev libltdl-dev libmad0-dev libid3tag0-dev libvorbis-dev libpng-dev libsndfile1-dev libwavpack-dev

Run the following:

autoreconf -i
./configure
make

If you wish to compile a static linked binary : Coming soon …

FreeBSD

You have three choices to install the dependencies:

1- Download each tarball from its website (only the ones you need) and compile them all:

OpencoreAMR-NB/WB http://sourceforge.net/projects/opencore-amr
AMR-NB/WB http://www.penguin.cz/~utx/amr
AO http://xiph.org/ao
FLAC http://flac.sourceforge.net
LADSPA http://www.ladspa.org
Lame MP3 encoder http://lame.sourceforge.net
Twolame MP2 enc. http://www.twolame.org
libltdl http://www.gnu.org/software/libtool
MAD MP3 decoder http://www.underbit.com/products/mad
MP3 ID3 tags https://sourceforge.net/projects/mad/files/libid3tag/
Magic http://www.darwinsys.com/file
Ogg Vorbis http://www.vorbis.com
Opus http://www.opus-codec.org/
PNG http://www.libpng.org/pub/png zlib
Sndfile http://www.mega-nerd.com/libsndfile
WavPack http://www.wavpack.com

2- Use ports <- Recommended!

audio/opencore-amr
audio/libao
audio/flac
audio/ladspa
audio/lame
audio/twolame
devel/libltdl
audio/libmad
audio/libid3tag
cad/magic
audio/libvorbis
graphics/png
audio/libsndfile
audio/wavpack

3- Use packages <- Fastest

pkg install opencore-amr libao flac ladspa twolame libltdl libmad libid3tag magic libvorbis png libsndfile wavpack

P.S. lame is not included in the package list because you need to compile it from ports.

As you can see I haven’t included opus in the list above due to some issues with this audio codec in O.Ss different from Linux.

Compiling

For a standard configuration:

autoreconf -i
./configure
make

If you want a static linked binary just take all the libraries you compiled before with extension *.a and copy them to a folder ex. /ex/folder and then:

autoreconf -i
./configure CFLAGS='-static' LDFLAGS='-static -L/ex/folder' --disable-shared --with-distro='FreeBSD 11'
make

macOS

Just use Brew -> https://brew.sh/

brew install opencore-amr libao flac two-lame libtool mad libid3tag libmagic libvorbis libpng libsndfile wavpack lame

Compiling

For a standard configuration:

autoreconf -i
./configure
make

If you want a static linked binary just take all the libraries you compiled before with extension *.a and copy them to a folder ex. /ex/folder, then run:

autoreconf -i
./configure LDFLAGS='-static -L/ex/folder' --disable-shared --with-distro='macOS 10.12 Sierra'
make

Logitechmediaserver, C-3PO and PCM to DSD conversion

 

In this tutorial I’m going to illustrate how to implement and enable PCM->DSD conversion on-the-fly on Logitech Media Server. This is possible thanks to the plugin C-3PO and a modified version of SoX and Squeezelite-R2.

For a complete introduction and description of what is Logitech Media Server and how to install and use it you can read this Marco Curti’s guide -> Introduction to Squeezebox Server (translation in English will be available soon)

SOX

First of all we have to substitute the original SoX binary package in LMS with the modified one; go to the directory that contains LMS binaries:

Linux:

cd /usr/share/squeezeboxserver/Bin/ARCH

Where “ARCH” is the architecture of your operative system.

FreeBSD:

cd /usr/local/share/logitechmediaserver/Bin

macOS:

cd /Library/PreferencePanes/Squeezebox.prefPane/Contents/server/Bin/darwin

Windows:

cd C:\Program Files\Squeezebox\server\Bin\MSWin32-x86-multi-thread

Then remove the “old” sox, download the modified one and rename it in “sox”.

*nix O.S.

rm sox && wget https://audiodigitale/repo/sox-VERSION

You can find all the versions of SoX for different O.S. here -> Download SoX

The binaries in the download area are statically linked, so you don’t have to install any dependencies!

If you want to compile SoX by yourself in the download area there is the .tar.gz archive of the same version of SoX used to compile the binaries; otherwise you can also clone this github repository
-> mansr/sox

If you have any doubt follow this guide -> How to compile SoX

NOTE: There is an unresolved bug in MacOS that doesn’t allow C-3PO to recognize the modified version of SoX

C-3PO

To install C-3PO please insert this repository in the lms plugin page :
http://www.marcoc1712.it/downloads/repository.xml

If you want to read more documentation about C-3PO follow this link -> C-3PO Transcoding Helper (translation in English will be available soon)

Project with source code on github -> marcoc1712/C-3PO

Particular instruction for FreeBSD: in this O.S. the directory that contains the binary of perl is different from linux, so you have to modify this file:

/var/db/logitechmediaserver/cache/InstalledPlugins/Plugins/C3PO/Bin/C-3PO

and replace #!/usr/bin/perl with #!/usr/local/bin/perl

Squeezelite-R2

Now your server should be ready to trascode PCM files to DSD, we just need to setup the client:

Please download the correct version for you O.S. here -> Squeezelite-R2

If you don’t know how to use it please read this guide -> Squeezelite-R2 Guide (translation in English will be available soon)

If you want to compile Squeezelite-R2 by yourself in the download area there is the .tar.gz archive of the same version of squeezelite-R2 used to compile the binaries; otherwise you can also clone this github repository -> marcoc1712/squeezelite-R2

If you have any doubt follow this guide -> How to compile Squeezelite-R2

Do you want to install and setup every single option of squeezelite easily? You can do it with Falcon, a practical and user-friendly web interface to manage every aspect of squeezelite! (Only for linux, beta)

Do you already know how to use squeezelite and you just want to start it at boot time?

P.S. Please pay attention when you set the scheduler and the niceness; if you don’t know what are you doing remove “-N $NICENESS -P $SCHEDULER” from the script. If you have any question about this init script ask your questions in the comments below.
