Role Overview
This role focuses on building real-time interactive audio systems for a mobile-first music learning experience. The goal is to make singing practice fun responsive and game-like using low-latency audio and clear feedback.
You will own everything related to voice input audio processing and musical feedback. This includes pitch detection rhythm timing and turning raw voice input into meaningful encouraging responses for users.
As an early technical hire you will help shape both the technical foundation and product direction.
Key Responsibilities
Real-Time Audio Systems
- Design and build low-latency audio input and playback systems for mobile and web
-
Handle audio challenges such as:
-
Buffers and sample rates
-
Device-specific behavior
-
Latency compensation
-
Echo handling and headphone behavior
-
- Ensure smooth and reliable real-time audio performance across devices
Voice Analysis & Feedback
-
Build or integrate systems for:
-
Monophonic pitch detection for singing and simple melodies
- Rhythm timing and onset detection to evaluate singing in time
-
- Convert noisy real-world voice input into clear friendly feedback such as:
-
Slightly flat
-
Late on the beat
-
Perfect timing
Interactive Vocal Experiences
-
Build and prototype interactive practice modes including:
-
Sing-back and call-and-response exercises
