Hi jack team .. hope you are well and safe .. i'm so happy to have an app
like jack and i've done the setup and activation and everything is
running smoothly ..i'm running pro tools 12 and the other DAW is Mixbus 6
on windows 10 64 bit .. but i have a major problem and i can't fix it .. so
please help me in this problem .. i'm a sound engineer and i've my own
system in my home studio .. i want to route pro tools channels into another
DAW for mixing .. but all i have in pro tools for jack as a audio interface
is for mono outputs (2 stereo outputs) so now i can route only 4 channels
from pro tools .. and i have almost 60 channel in pro tools .. so how i
increase the outputs of jack in order to appear in pro tools i/o setup page
.. so i can route as many channels as i can from pro tools to any other DAW
.. please help me in this issue because i put my work on hold till i fix
this or know how to make jack with many outputs .. thanks and i really
appreciate your help .. stay safe
I am wondering if anyone is upgrading Jack Audio for Mac or tried using the
driver on a 64 bit mac.
the JackPilot binary was created in 2011 so I am thinking JackRouter might
need to be updated.
Can anyone validate this and if so is there a project tro update JackRouter
Looking for help to create a cross platform application that will listen
from speaker audio. Need help.
Open to any level of help...
- guide me
- provide me a simple utility
- engage for long term
Is it possible to use Jack Audio to capture audio from the speaker on Mac.
I want to save the audio in a file. So long as it works on Catalina or
above is fine.
thanks in advance
I believe this means capturing in the I/O Kit or AUHAL
Howdy jack-audio people.
It's good to have the list back!
I have been developing a collection of programs that work together for
radio automation. It's a port of a project I wrote and use currently
under OSX to run a radio station I own. At this point, I have all the
core stuff working on Ubuntu, less a new UI, which I have not written
yet. But that is mostly OK because my old OSX UI can control most of
the functions in the new components, and will work as I transition
So that bring me to the mostly working part. I have been testing an
testing and testing, and have come across a problem where my programs
cause jackd to crash after running as a system for a few days. The
core-mixer program is persistent. Media players are forked by, and
connect back to the core-mixer (arServer) to play their files, etc., as
needed, then quit. It appears this repeated life cycle of the media
players are the cause, because the jackd crash always occurs just after
a media player disconnects from jackd. I am running Ubuntu Studio
tools, so as soon as jackd quits, it is re-run. Crashes again one to
two more times, then runs without further disturbance, except that my
core-mixer it written to quits when it get notice that jackd shutdown.
All my core code is in straight C and can be found at
https://github.com/eafunk/audiorack. Jackd does not crash with the
core-mixer running with a single audio source connected to it, with out
the media players loading and unloading. Neither does it quick when
left alone with an audio source hard-routed to a destination without
the core-mixer running.
Can any one suggest how I could debug jackd to figure out what my
program is doing to cause the crash? Debugging my code is pointless
here, because it doesn't crashes when jackd does. Any pointers on how
I can build jackd (the dbus multi-processor version) for debugging?
Build tools give me nightmares, but I have to dig in to get this sorted
I'm in the process of building a small application that utilises Jack in
order to interface with audio hardware. Specifically, although this detail
is only partially relevant, I'm writing it in Rust (using some community
I was wondering what the thread safety guarantees of calling the processing
callback are. Specifically, I was wondering if it can be guaranteed that
the callback will only be called on a single thread at any given time?
This is primarily because it determines whether or not it is required for
the callback to be marked as "Sync" in Rust - which would indicate that the
callback's data must be thread safe, a restriction I'd prefer to avoid.
Thanks in advance.
I just tried to run JACK2 on OSX Catalina. I installed the binary and it sais that it is not supported for Catalina anymore.
The first try of compiling it on my machine failed. I couldn’t spend much time investigating the current problem but it obviously deals with the 32-Bit build.
Can anyone send me a pointer how to possibly quickly resolve the build issue ?

I've been trying to find a good way to a stream of audio from jack into opusenc (the official opus encoder tool) and then pass it to something like oggfwd to send to Icecast. However, a few different things I've tried in python haven't worked out, and I'm trying to not have to rely on an "audio file player" (like sox or pyaudio) to sit in the middle. Now I'm wondering if there's a way I can get the raw pcm data from jack. Is this possible? Is there an existing tool?
