Octave exceeds ANSI standards for a real-time analyzer. Each sub-band is calculated with a bandpass Butterworth filter, giving constant resolution across the entire spectrum range.

All calculations are performed with Apple's proprietary Accelerate library, giving the fastest and most accurate filtering on the iPhone. All graphics are rendered with OpenGL, so you never miss a peak.

You might need to bring out the big guns from time to time, but with Octave, you'll always have an RTA in your pocket, no matter what.
