In this episode of Mobile Development with Fexingo, hosts Lucas and Luna explore how on-device AI is enabling real-time guitar chord detection in mobile apps. They dive into the technical challenge of identifying chords from raw audio using small neural networks like convolutional neural networks (CNNs) and CRNNs, optimized to run on phones without a cloud round-trip. With demo apps like Chord AI and Yousician as examples, they discuss how audio preprocessing, chroma features, and model distillation make sub-100-millisecond chord recognition possible. Lucas explains the trade-offs between accuracy and latency, and why training on synthetic data from tools like PyTorch's audio libraries is key. The episode also touches on the business angle: how app developers monetize these features via freemium models and subscription tiers. A concrete, technical look at a niche but growing use case for edge AI in mobile music education.
