Importing detectAudioFormat from server/replit_integrations/audio/client.ts pulls in module-level side effects (e.g., OpenAI client initialization) just to validate uploads. Consider moving/re-exporting detectAudioFormat from a side-effect-free utility module so route initialization doesn’t depend on audio integration setup.
