hosts some great open source (free) DJing software-
Drawback is: the free pre compiled Linux Downloads you can get are not built to process Apple AAC/m4a audio files such as are widely used within iTunes. This is because of Apple & other patent issues-
On MACs & PCs it’s taken care of by their own pre installed Libraries.
Yet you are free to build it yourself legally and freely.
But don’t distribute the results. Such is the Law.
Also the Default will not handle my old collection of .MOD/.IT (Screamtracker) audio files from Amiga days, 1980’s era…
Not Commonly Needed. But I have some!
Also, although the site seems to suggest Windows .wma files cannot be handled. my compile seemed to read them Just Fine.. with an Exception: Microsoft code a PRO format.
“Windows Media Audio 10 Professional” reports the “medianfo” utility in Ubuntu : (
These load as a BLANK timeline with no spectrograph-
and won’t make sound. Use ffmpeg to convert them. Too Bad.
I wanted to be able to read all possible audio formats without having to convert anything. This Compile seemed to work for me in Linux using Mint ver 20 based on Ubuntu 19 & the latest ‘stable’ Branch of Mixxx, which is ver 2.4.4 as of Oct 2020
Not Kosher– But, I found it easiest to run everything as ‘root’ rather than ‘sudo’ this that & the other. Some tricky instructions are indeed here:
but I became Confused in the footsteps of those for whom this is familiar territory. For Starters:
#apt-get install cmake
Now we need to put in ‘development’ Headers and info about the Libraries that will be Used
(Don’t worry too much about ‘already installed’ warnings here)
So, in My Case, as Root, on One Line::
#apt-get install g++ git scons libportmidi-dev libopusfile-dev libshout-dev libtag1-dev libprotobuf-dev protobuf-compiler libusb-1.0-0-dev libfftw3-dev libmad0-dev portaudio19-dev libchromaprint-dev librubberband-dev libsqlite3-dev libid3tag0-dev libflac-dev libsndfile-dev libupower-glib-dev libavcodec-dev libavformat-dev libavutil-dev libswresample-dev libgl-dev liblilv-dev libjack-dev libjack0 portaudio19-dev libmp3lame-dev libebur128-dev
(lots of messages– Look For Error)
#apt-get install qt5-default qtdeclarative5-dev libqt5opengl5-dev qtscript5-dev libqt5svg5-dev libqt5x11extras5-dev libqt5sql5-sqlite libmodplug-dev
(More Blurbs– Look for Errors)
Now! Onto the Build Process: (For Current stable ver 2.2.x) #cd /usr/src #md git #cd git #git clone -b2.2 https://github.com/mixxxdj/mixxx #cd mixxx #scons
faad=1 ffmpeg=1prefix=/usr/local -j `nproc` optimize=native
nproc will execute the “nproc” command to return the number of CPUs you have to the -j parameter, so the compiler will work in parallel. Wow. Look at TOP where I have an 8 core laptop– This made the cooling fan run and took about 5 mins to compile. I get compile time Warnings in Blue, nothing in red..

This will create the following installs:
Ideally copy this last file onto your Desktop
BEFORE running mixxx
Check in ~/.mixxx
in case you have run things before, perhaps move everything out of that folder. It will be re created and store your (NON ROOT) launch of mixxx
