Live Audio Decoder

Listen through your microphone or external audio input, detect CW/Morse tones, and transcribe spoken audio through My Vision Media AI Labs.

Checking browser support...
Important: The Labs transcript is for spoken words. Morse/CW beeps are decoded by the browser CW decoder below.

Click Start Listening once to allow microphone access. After permission is allowed, available microphones will appear here.

Most CW sidetones are around 600–800 Hz. Adjust if dots and dashes are missed.

Default uses the legacy transcription endpoint first to avoid newer model/project restrictions.

Longer chunks use fewer requests and reduce cost.

Notes

Your developer key stays server-side. The browser sends audio chunks to /decoder/transcribe.php. That PHP file loads the saved key from your Admin OpenAI Settings and keeps it server-side.

System audio: browsers cannot hear speaker output unless your operating system exposes it as an input device.
