Could you build this?
Partial While the quiz logic and UI are straightforward, real-time polyphonic chord recognition and single-note pitch detection running robustly on an iPhone mic in noisy real-world conditions requires specialized DSP/audio ML models.
What it would actually take: A native iOS app in Swift using the AVAudioEngine framework for mic streaming. Single-note pitch detection can use the YIN algorithm or Crepe, but polyphonic chord detection requires specialized FFT peak analysis or a lightweight CoreML model trained on isolated/strummed guitar audio spectrograms. Expertise in digital signal processing (DSP) and CoreML audio classification is required to handle harmonic overtones, background noise, and latency.
