Impulse Response Measurer audio device

Hi,

the problem concerns ImpulseResponseMeasurer that does not correctly identify the audio devices connected to my mac book.

If I run adiodevinfo:

A=audiodevinfo

ans = 

  struct with fields:

     input: [1×3 struct]
    output: [1×6 struct]
    
A.input.Name

ans =

    'USB AUDIO  CODEC (Core Audio)'


ans =

    'Microfono MacBook Pro (Core Audio)'


ans =

    'Microsoft Teams Audio (Core Audio)'

But in ImpulseResponseMeasurer the only available device is Microsoft Teams Audio

Is there a way to tell to ImpulseResponseMeasurer to use a different I/O device (i.e. USB AUDIO CODEC)?

Thanks in advance

Could you also list the output names?

Hi Jimmi

this is the result

A=audiodevinfo
A = 

  struct with fields:

     input: [1×3 struct]
    output: [1×6 struct]
    
A.output.Name

ans =

    'E4.5BT (Core Audio)'

ans =

    '216KKMR (Core Audio)'

ans =

    'USB AUDIO  CODEC (Core Audio)'

ans =

    'Cuffie esterne (Core Audio)'

ans =

    'Altoparlanti MacBook Pro (Core Audio)'

ans =

    'Microsoft Teams Audio (Core Audio)'

May I ask what the device is? Does it show up in the command window if you try this?

>> getAudioDevices(audioPlayerRecorder)'

The USB AUDIO CODEC device is an external sound card built into a small multitrack mixer that I connect to my Mac via USB to record analog instruments.

This is the result of the command:

getAudioDevices(audioPlayerRecorder)

ans =

  1×2 cell array

    {'Default'}    {'Microsoft Teams Audio'}

I'm trying to figure out if that device supports full duplex (simultaneous input and output at a common sample rate). Is the USB AUDIO CODEC showing up in the outputs a different device (ex: DAC)?
