Any analyzer can only be as accurate as it's microphone allows. Good analyzers/DSP room correction systems come with calibrated mics. One has to wonder what the frequency curve might look like, of a telephone's mic.
Are phone app spectrum analyzers accurate?
I'm constantly amazed at the cool things a smart phone can do. There are several spec. analyzer apps available but I'm wondering if they're really accurate enough to use for system tuning? I've tried a couple of these and I like Speedy Spectrum and Spectrum Analyze (for android) the best for features and apparent accuracy.
My old Heathkit portable analyzer looks to be toast (yeah--I'm that old).
What are the thoughts from the hive?
