HARK is a lightweight Android app that turns your phone into a live microphone, streaming audio directly to your hearing aids (or any headset) using Bluetooth. HARK replaces the need for expensive “table microphone” hardware with a single button on your phone. It uses a C++ codebad that allows for low latency, with a Kotlin front-end.
- Captures real-time audio from the phone’s microphone
- Streams it via Bluetooth (ASHA-compatible devices preferred)
- Utilizes Google's Oboe Engine to process the audio
- Acts as a portable table mic for hearing aid users
- Simple on/off toggle
- Transcription of audio being streamed (Powered by OpenAI Whisper)
- Hearing aid users in classrooms, meetings, or noisy environments
- Anyone who wants a no-frills, instantly available hearing streamer
- Especially useful on Android devices with ASHA (Audio Streaming for Hearing Aids) support

I built HARK because I needed it — and I hope it helps others too.
