Unpopular microphone dry goods | The radio truth that no one tells in the whole network, avoiding all IQ taxes.

The whole network microphone tutorial is all copied: directivity, capacitance vs moving coil, noise reduction switch

It's all old words from five years ago!

Today, dry goods that have never been rotten in the streets and within the industry have been sent.

No blowing parameters, no goods, easy to understand, novices can directly save thousands of dollars on the pit after reading it.

The most expensive thing is not the microphone, but the "radio background color"
Many people wonder: There is not much difference in noise reduction between hundreds and thousands of microphones. Why is it twice as expensive?

It's not a definition gap

The core difference is the background color of the radio.

Cheap wheat: Noise reduction is violent sound cutting. When cutting off the noise, you will cut off the details of your breath, nasal sound and human voice. The sound is stuffy, mechanical and robot-like.

Professional Mai: Keep the background color of human voice, only filter out the ambient noise, and the human voice is moist and textured.

Minimalist judgment:

Listen to your inspiratory sound after the radio, natural softness = good background color.

Harsh inhalation and direct disappearance = violent noise reduction, no matter how expensive the wheat is, don't buy it.

2 90% of wheat spraying is not a pan with a wind shield!
The whole network teaches to put on sponges and wool covers to prevent wheat spraying, which is purely a temporary solution rather than a permanent cure.

Cold knowledge of the industry: wheat spraying = direct airflow, regardless of the wind.

Universal zero-cost solution (without any accessories)

Don't point the microphone at your mouth!

Move down and aim at the corner of your mouth 45 to avoid the expiratory flow in front of you.

Effect > Double windproof wool cover

Lightning protection: Thickened windproof sponge will only eat high frequency, and the voice will become mushy, and the more you set it, the worse it will be.

3 wireless disconnection, 99% is not signal difference.
Most people trample on this misunderstanding:

Outdoor radio staccato, murmur, intermittent jam

It's not too far, it's not the poor quality of wheat.

The culprit is: interference of mobile phone charging current.

Plug in the charger and use the wireless microphone to receive the radio.

The current directly disrupts the audio frequency band, and even the best flagship wheat will explode.

Remedy: unplug the charging cable during the whole shooting.

If the power is not enough to buy an external charging treasure, the noise can be cured by staying away from the body of the mobile phone.

4 Concealed by merchants: electret microphone pit
On the market, 80% of the 100-yuan fair-price wheat, headphones bring their own wheat, and conference USB wheat.

All are electret heads.

Merchants all keep their mouths shut!

Features: extremely low cost and unstable radio reception.

When the temperature is higher than 28℃ and the weather is humid, the sound quality will directly roll over.

During the day, the radio is clear, and in the evening, the noise directly explodes and the voice is distorted.

Identification method: look at the details page, not to mention the material of the sound head, which is 100% electret.

5 The biggest directional lie: Omni-directional radio is wider
Businessman's words: Choose all directions for outdoor video shooting, with wide radio range.

It is purely misleading for novices!

Real principle:

Heart-shaped pointing: closing the positive voice and shielding the noise.

Omni-directional: No distinction is made between sound sources, and human voice, wind, passerby noise and echo are all included equally.

The noisier the outdoor environment, the more disastrous the omni-directional radio is.

Universal formula:

All vocal recordings | Live, Oral, vlog→ Only choose heart-shaped pointing.

Only multi-person round-table dialogue → use all directions.

The louder the volume, the more unpleasant the voice is.
Novice common fault: the radio volume is full, and I feel louder and clearer.

Red line of audio industry: gain overload is irreversible

When the volume is full, it will produce invisible broken sound, the waveform will not be visible to the naked eye, and the ears will be dry and harsh.

Golden radio threshold:

The peak volume of speech is stuck at 70% of the volume bar.

Leave 30% margin, the voice is full and clean, and the color will be adjusted casually in the later period.

Full volume = destroy the original audio directly, and you can't save it after repairing it later

Good radio reception never depends on expensive microphones.

Avoid current interference, violent noise reduction and wrong angle.

Nuoyin's wheat can also shoot a million-level vocal texture.
