Streaming audio to OpenAI in your browser is cool… until you deal with PCM16.

The browser gives you Float32 audio. The API expects PCM16 at 24kHz.

That means:

Float32 → clamp → Int16 → base64 → send to realtime api

If you don’t handle the conversion properly, you’ll hear it right away — crackling, silence, or wrong pitch.
