I am using Audition 2014.0.1, nd am trying to play audio on multiple output devices simultaneously. My friend has an older audition version, where it is pretty straightforward, but I can't find how this is done in my version.
I open a multitrack session, and prepp with multiple mono signals. I now try to select playback device, but my only options are the left and right channels of my selected default device. I wish to use more than one device, to play three or more mono signals at the same time. How can I achieve this?
The only way that I'm aware of to do this is to use a composite 'transfer' driver like ASIO4ALL. This creates aggregate devices, at the cost of some latency, but you should then be able to select more output sources. Should point out that not being able to do this with ASIO isn't Audition's fault - it's a part of the ASIO spec, and what ASIO4ALL is doing is taking Audition's ASIO stream and redirecting it using a 'normal' windows driver.
I tried out ASIO4ALL, and it worked perfectly. I selected the ASIO4ALL 'Device' in audition, and could then choose from all devices selected in the ASIO4ALL interface, I could choose individually for each signal, so I could play different signals on each device. Just what I wanted! Thank you for your help
Are you on a Mac or a PC? Using multiple playback devices at once is very tricky since, ideally, all audio interfaces need somehow to have their sample clocks synchronised together. This is why normally you buy a multichannel audio interface that can play back many channels at once from the same device. Depending on your audio interfaces and what operating system you are using it may be possible to make an aggregate device using several different ones either in the Mac's Core Audio settings or by using something like ASIO4All on a PC. So please tell us which type of computer you are using and what audio interfaces you have connected?
I am on a windows 10 machine. Exact synchronization isn't critical for what I'm doing. within a few ms would be ok. I am using audition, and have only standard stuff otherwise.
I wish to use the left and right channel of the analog output, and additionally one or two USB devices, and play audio on them simultaneously.
Thank you for your tips, I will look into ASIO4All.
Ok, A little more clarification:
What I want to do is to use three or four separate mono signals, play two of them on speakers (left and right), and the others on USB devices. Windows can handle playing different sound on different devices at the same time, for instance playing from audition on a non-default device, and playing from youtube on the default, I just want to manage all the tracks from audition, so I can play them (reasonably) synchronized.
