recording mic array 2.0 with 6 channels

Post by rui.zhou » Mon Nov 19, 2018 6:47 pm

hi
wonder if how to record mic array 2.0 with 6 channels.
update firmware with 6_channels.bin

1.open audacity
2. choose device
3.choose 6 channels
4.recording
5.replaying

my question are:
1. at step 2, should I use headphone:mic0 or mic1?
2. after record stop, audacity doesn't show 'channel 0~6', instead it shows audio track 1~6, is it correct?
3.track 1 looks a mix of all sounds(include noise), the other tracks like a recording with specify location(e.g. track 2 is rear left, track3 is front left..etc)
4. I am expecting a track with noise reduction, how to do it?sounds the track 1 or track 2 can't meet my expectation.

Hi there,

If you use the windows, please select the windows wasa as below. the processed data is in channel 0, the channel1~4 are raw data, the channel 5 is playback. for the noise reduction, please refer to channel 0. thanks.
