🎙 Step 2: Record with Silence Buffer

Before speaking:

• Leave 3–4 seconds of silence at the beginning of your recording. This helps with accurate noise reduction later.
• Do the same at the end of your recording.

Press the red Record button, speak clearly, then hit Space or Stop when finished.

⚠️ Important Notes on Noise Reduction

• While Audacity’s noise reduction works well, overuse can cause artifacts—a metallic or distorted sound.
• For heavy background noise, consider professional tools like iZotope RX (paid software).

🎤 Alternate Tools for Audio Recording

While Audacity is great for post-production, if you prefer real-time filters, you can explore:
