    Hello Antony, this is Julian from the Bunny Studio Quality Check Team.

    Thanks for reaching out!

    I've heard the sample, and indeed, it presents Hiss/White noise. Next, I'll leave you a guide on how to overcome such an issue: 

    1. Use High-Quality Equipment

    • Microphone: Ensure you are using a good quality microphone that is suited to your recording environment. Condenser microphones, for instance, can be sensitive to noise, so placement and environment are key.
    • Audio Interface/Preamp: A good quality audio interface or preamp can help reduce unwanted noise. If the gain on your interface is too high, it may introduce hiss, so ensure you are adjusting the gain properly.

    2. Proper Gain Staging

    • Gain Levels: Keep your microphone gain levels at an appropriate range. If you increase the gain too much, it will amplify not only your voice but also background noise, including hiss. Aim for a strong, clear signal without over-amplifying.
    • Mic Placement: Position the microphone closer to your mouth (about 6–12 inches) without causing plosives. This allows you to lower the gain, reducing noise while maintaining clarity.

    3. Control Your Recording Environment

    • Room Treatment: Hiss may come from the ambient noise in the room (fans, air conditioners, etc.). Ensure your room is acoustically treated with soundproofing materials like foam panels, carpets, and curtains to reduce background noise.
    • Turn Off Noisy Equipment: Devices like computers, fans, or other electronics can introduce hiss. If possible, turn off or distance yourself from such equipment while recording.

    4. Microphone Placement and Settings

    • Directionality: Use a cardioid microphone that picks up sound from the front and minimizes background noise from the sides and rear. Adjusting your microphone’s directional settings can help reduce ambient noise.
    • Pop Filter/Windscreen: Use a pop filter to minimize noise from your breath hitting the microphone directly.

    5. Post-Production Techniques

    • Noise Reduction Plugin: If some hiss still gets into the recording, you can use noise reduction plugins or software like iZotope RX, Audacity, or Adobe Audition. However, use them sparingly as aggressive noise reduction can affect the quality of your voice and make it sound unnatural.
    • High-Pass Filter: Use a high-pass filter to remove low-frequency noise below 80–100 Hz, which can help reduce background hum and hiss without affecting your vocal range.
    • EQ Adjustment: Carefully adjusting the EQ to cut high-frequency noise (around 8–10 kHz) can help, but be mindful not to remove too much, as it may affect the clarity of your voice.

    6. Check Cables and Connections

    • Use Shielded Cables: Poor-quality or old cables can introduce noise into your signal. Ensure that your cables are properly shielded and that the connections are secure.
    • Avoid Long Cables: Using longer cables than necessary can increase the chances of picking up interference, which contributes to hiss.

    7. Power Supply and Electrical Interference

    • Ground Loops: Sometimes hiss can come from ground loops or electrical interference. Ensure all your equipment is plugged into the same power source to reduce interference. You can also use ground loop isolators if necessary.

    By following these steps, you should notice a significant reduction in hiss or white noise in your recordings. Remember, achieving high-quality audio is a combination of good equipment, proper setup, and careful post-production.

    Best of luck with your future recordings, and feel free to reach out if you need further assistance!
