Many creators at the start of their journey completely ignore the importance of audio in video, focusing exclusively on image resolution. This is a costly mistake.

Have you ever closed a video after a few seconds because of an annoying hiss, echo, or because the voice was too quiet? That is exactly what your clients do too. At NC Media, we have a golden rule: “People forgive a pixelated image, but they never forgive bad sound.”

Here is why you need to prioritize the microphone and how to get studio-quality sound in 3 steps.

1. Why is the Importance of Audio in Video So Critical?

The explanation is biological. Poor quality sound (with background noise or distortion) is tiring for the brain. The viewer has to make an extra cognitive effort to decipher the message, which quickly leads to frustration and abandonment.

On the other hand, a clear, warm, and present voice creates intimacy and authority. If you want to sell or persuade, your voice must be heard flawlessly.

2. Distance is the Enemy: Phone vs. Lavalier

Modern phone microphones are decent, but they have a physical limit. If you move more than 50 cm away from the phone, your voice will start to sound "hollow" or "like you're in a barrel," capturing all the ambient noise.

The Solution: Investing in a wireless lavalier. This brings the microphone close to the sound source (your mouth), eliminating distance. Whether you move around or turn your back, the sound remains constant and clear. It is a €100 investment that makes a video look like €1000.

3. Eliminating Echo and Music Mixing

Even the most expensive microphone will sound bad in an empty room.

Echo (Reverb): Sound bounces off empty walls and tiles. To fix this, you need to "soften" the room. Use rugs, thick curtains, or furniture to absorb the sound.
Music: The role of background music is to support the atmosphere, not cover the message. In editing, ensure the music volume is at a maximum of 10-15% of your voice volume.
