 # How to configure a Microphone Array

 The Speech Devices SDK initially supported microphone arrays by selecting from a fixed set of configurations.

 ## Windows
-On Windows the microphone array geometry information is automatically obtained from the audio driver. So, the properties `DeviceGeometry` and `SelectedGeometry` as well as the new property `MicArrayGeometryConfigFile` are optional. We use the [JSON file](https://aka.ms/sdsdk-micarray-json) provided using `MicArrayGeometryConfigFile` for only getting the beamforming range.

-If a microphone array is specified using `AudioConfig::FromMicrophoneInput`, then we use the specified microphone. If microphone is not specified or `AudioConfig::FromDefaultMicrophoneInput` is called, then we use the default microphone which is specified in Sound settings on Windows.
-The Microsoft Audio Stack in the Speech Devices SDK only supports down sampling for sample rates that are integral multiples of 16KHz.

 ## Linux
-On Linux the microphone geometry information must be provided. The use of `DeviceGeometry` and `SelectedGeometry` remains supported. It can also be provided via the JSON file using the `MicArrayGeometryConfigFile` property. Similar to Windows, the beamforming range cane be provided by the JSON file.

 If a microphone array is specified using `AudioConfig::FromMicrophoneInput`, then we use the specified microphone. If a microphone is not specified or `AudioConfig::FromDefaultMicrophoneInput` is called, then we record from ALSA device named *default*. By default, *default* always points to card 0 device 0, but users can change it in the `asound.conf` file. 
 
-The Microsoft Audio Stack in the Speech Devices SDK only supports downsampling for sample rates that are integral multiples of 16KHz. Additionally the following formats are supported: 32-bit IEEE little endian float, 32-bit little endian signed int, 24-bit little endian signed int, 16-bit little endian signed int and 8-bit signed int.

 ## Android
-Currently only [Roobo v1](speech-devices-sdk-android-quickstart.md) is supported by te Speech Devices SDK. Behavior is same as previous releases, except now `MicArrayGeometryConfigFile` property can be used to specify JSON file containing beamforming range.
