    4 channel audio output from a video source

    by Fabioquiet » Wed Nov 06, 2019 12:08 pm

    Hello
    i need to play 4 channel audio from a video. i'm using a video source to light many strip led single pixel by artnet. I know that someone already wrote something in the forum, but i didn't understand well. So i exported a .mov Apple pro res 422 HQ with 4 channel audio. So when i play it on madmapper how can I link the 4 audio channel to 4 output of my audioboard? I thought that it could be automaticly but my audioboard still playing only LR channel.
    Thanks

    Hi,
    Are you on macOS or Windows ?
    Are you using MadMapper 3.7 ?
    You have to select the audio interface in MadMapper / Preferences / Audio / Audio Output.
    If you're on Windows, you have to choose ASIO driver to have multichannel support.
    Cheers

    You have chosen ASIO driver in preferences / Audio / Driver Type ?

    Hello
    after more than 2 years I renew the question. I'm working on a multitrack audio project again, and I can't send 4 audio tracks from madmapper. I select the sound card (focusrite 6i6) but then I can only listen to the first 2 channels, the 3-4 not. Mad-matt suggested to select ASIO from the preferences, but I think it is only for PC, while for mac it seems that it is enough to select the sound card. I am using OSX 10.15 + Madmapper 4 latest version. Suggestions? Thank you

    Indeed ASIO in only for Windows.
    Actually you havethe6 channels opened. The "Audio Analysis Channels" you can select from preferences are the one used for beat detection / general waveform and spectrum used in Materials. You should see al channels there, as in following screenshot:

    But you can use all the channels for controlling parameters:
    - Right click on a widget and choose "Add Control / Audio"
    - In Controls List, select your audio control, press the "Channel" list button and you'll see all available channels.

    If you can only see channels 1 & 2, please send a screenshot of preferences / audio tab
