मीटिंग और कॉलिंग ऐप्स में ऑडियो सेटिंग्स (Meeting Apps Audio)
Zoom, Google Meet या Discord में साफ़ आवाज़ के लिए टिप्स:
In-App Audio Hardware Selection
Do not rely on "Same as System". Explicitly pick your USB microphone or headset from the app audio settings.
ऐप की ऑडियो सेटिंग्स में जाकर अपने ईयरफ़ोन या यूएसबी माइक को सीधे चुनें, "Same as System" पर निर्भर न रहें।
Echo & Feedback Elimination
If attendees complain about hearing their own voices back, switch from laptop speakers to earphones or headphones.
यदि मीटिंग में मौजूद अन्य लोगों को अपनी ही आवाज़ गूंजती हुई सुनाई दे, तो लैपटॉप के स्पीकर बंद करके ईयरफ़ोन लगाएं।
Background Noise Suppression
Enable Noise Suppression in Zoom (Medium/High) or Krisp in Discord to filter out keyboard typing and fan noise.
ज़ूम या डिस्कॉर्ड में नॉइज़ सप्रेशन (Noise Suppression) ऑन करें जिससे पंखे की सरसराहट या कीबोर्ड की आवाज़ न जाए।
