11Purpose:
12   This Library is used to decode and reconstruct the audio signal
13   produced by ST MEMS microphone (MP45Dxxx, MP34Dxxx).
14
15Description:
16   This library, written by STMicroelectronics, is used to convert an audio
17   stream from PDM format to PCM format through a signal filtering and
18   decimation.
19
20   Library APIs:
21      - Open_PDM_Filter_Init()    /* Init the OpenPDM2PCM library */
22      - Open_PDM_Filter_64()      /* Filter and decimate stream by 64 */
23      - Open_PDM_Filter_128()     /* Filter and decimate stream by 128 */

26Dependencies:
27   This library depends by Zephyr mpxxdtyy driver and is linked statically.
28   This library will be used by a standard Zephyr microphone driver
29   (./drivers/audio/).
