Global settings
Go to Project -> Project Settings -> General -> Audio -> Input (Check Advance Settings).
You will see a bunch of settings there.
Microphone transcription feeds Whisper at 16000 Hz. The addon resamples captured audio from the actual runtime mix rate reported by AudioServer.get_mix_rate().
Optional: set Project Settings -> Audio -> Driver -> Mix Rate (audio/driver/mix_rate) to 16000 to avoid resampling overhead. This may reduce overall game audio quality, so only use it if speech transcription is the main audio workload. Godot may still use a different runtime mix rate on some platforms or devices; verify with AudioServer.get_mix_rate(). If the runtime mix rate is not 16000, the addon will resample.
