We are working on one product, were we need to get microphone data with different sample rate like (8kHz, 16.5kHz, 44.1kHz).
I searched for the same and have some queries regarding the same as below:
As we need to have different sampling rate of Audio, we can't use the I2S Digital Microphone.
But there is an confusion on Analog & PDM Microphone.
I understand that Analog Microphone + Audio Codec can be implemented for configurable sample rate. But what about PDM Microphone + PDM receiver with Decimation filter to get the desired sample rate?
Does the PDM Mic+PDM Recceiver with Decimation filter will do the job of desired sample rate with good quality or i need to follow Analog Microphone + Audio Codec the approach for good performance?
Looking for valuable feedback
