6 channel mic in audio codec with DSP mode

Hello,

I am thinking of making a 6 channel shield. Could you suggest a code from Wolfson or Cirrus logic which has 6 channel input and works on DSP mode?Or could you guide me how to do it for I2S enabled codec? I am looking at this one

there are 2 ways to do 6 channels: get 3 codecs, each on their own I2s or SPI line, or use the codec you found. there are a few other 6 channel codecs out there, but that is the best one (i am planning on using it for a project soon). i havent done any work with it yet, so i cant say how best to use it. it might be best to put the codec in master mode. it looks like TDM might be compatible with SPI, otherwise you will have to use I2S
