we are currently working on a project where the phase of a sampled signal is important. We are planing of using ADMP441 for this purpose. We have a couple of questions:
1: Are there any number saying how accurate the signal is sampled with respect to the phase? If two microphones are locate nearby each other will the sampled signal be in phase?
2: When two microphones are coupled in I2S L/R configuration, when are the microphones sampled. Synchronous (when WS goes low) or with respect to the WS signal (WS going low = sampling left; WS going high = sampling right)?
