How do I choose the best lavalier mics for capturing clear audio during outdoor conversations?
Lavalier mics are also known as lapel mics, collar mics, or personal mics.
Wireless lavalier mics can transmit audio using radio frequency (RF) or Bluetooth.
RF lavalier mics generally provide better sound quality and range than Bluetooth mics.
Omnidirectional lavalier mics capture sound from all directions, while unidirectional mics (cardioid, supercardioid) pick up sound mainly from the front.
The proximity effect, more pronounced in directional mics, makes voices sound deeper and richer as the mic gets closer to the sound source.
Wind noise can be minimized using foam or furry windscreens or by adjusting mic placement.
To reduce interference between two wireless mics, use different frequencies, increase the distance between them, or use directional mics.
Lavalier mics with built-in shock mounts or foam covers can help reduce handling noise.
When connecting multiple lavalier mics to a single device, use a mixer or a recorder with multiple inputs and adjust the input levels for each mic.
Phantom power, typically 48V, is required for some professional-grade lavalier mics, which can be supplied by a mixer or an external power source.
Some smartphones and tablets can record from two lavalier mics using a USB-C adapter or a Lightning connector, but not all recording apps support multichannel input.
To record two lavalier mics on a smartphone, consider using two 3.5mm TRS lavalier mics with a 3.5mm splitter, but ensure that the phone's recording app supports multichannel input.
Lavalier mics with a locking connector can prevent accidental disconnections during use.
When using lavalier mics with wireless transmitters, be aware of the transmitter's battery life and range.
Lavalier mics with active noise cancellation or background noise reduction can improve sound quality in noisy environments.
