Simple Router not in toolbox in SigmaStudio both 3.11 & 3.12

Hi,

I cannot find the simple router tools in the toolbox in either of the installed versions of SigmaStudio.

I am trying to build a mix matrix like this

https://wiki.analog.com/resources/tools-software/sigmastudio/toolbox/mixerssplitters/audiosignalrouterindexselectable

Am I supposed to use NxM Mixer ( non-linear ) ?

I've made an 8x8 box with NxM mixer but it looks bar bones ! where is the I2C controls for this so I can control the matrix from my

MC ?

sorry I am new to SigmaStudio so this is probably a very stupid question.. unless flexible routing is not possible with the AD1941 dsp IC ?

I'm running windows 8 64bit and both versions of the software installed without error.

any clue would be much welcomed

  • Hi Dave, thanks for you reply.

    Thanks for letting me know I can do flexible routing with the NxM mixer.

    I did notice the register values pop up when I changed numbers on the matrix in sigmastudio so I'm guessing I write to those values over I2C to control them.

    I'll read more about safeload in the data sheet and try and discover what it actually is ! I asume its not zero crossing volume changes.

    it makes sence the registers change when you re-program the device. A shame but I can see why.

    I have wired up an AD1941 i2c version and will hopefully manage to program it tommorow with the USBi programmer. Thats if I can get the clock running from external or gernerate one locally.

    I'm actially just trying to make an 8 : 2 stereo mixer for them moment with indipendant headphone volume.

    I'm doing the input Gain with other PGA's so its just main volume and panning etc..

    If there is enough power in the DSP I'll add some basic low pass filters and a limiter ( compressor ) on each channel.

    The tricky part will no dought be the 8 balance ( pans ) I was thinking of splitting the 8 channels and having 2 x 8 mixers and then panning with I2C Control with the MC.

    Eventually I'l like to add multichannel recording with 2 channel mix doen recording direct to SSD hardisk.

    I asume I'll need to move up to Sharc DSP or higher for this. shame since I'd love to stay with the snaller low power chip !

    One potential feture I really like the look of is the ability to send out level values for real time metering on each channel.

    Anyway, will try and remember to post back here if I get mix routing all working.
