Narration:

For narration, the microphone should be positioned at a distance of about 12 inches to 18 inches from the mouth to capture a more natural and even tone. The microphone should be positioned slightly above the mouth to capture the richness of the voice.

Audiobooks:

For audiobooks, the microphone should be positioned at a distance of about 12 inches to 18 inches from the mouth and slightly above it to capture a clear and consistent tone. The microphone should be positioned at an angle to avoid plosives and mouth noises.

Podcasts:

For podcasts, the microphone should be positioned at a distance of about 6 inches to 8 inches from the mouth to capture a natural and conversational tone. The microphone should be positioned at an angle to avoid plosives and sibilance.

Plosives and pop filter placement for microphone use

Plosives are sharp bursts of air that occur during speech, such as the sounds “P” and “B.” These sounds can be particularly challenging for microphones to capture and can result in unwanted sounds in the recording.

To prevent plosives from being picked up by the microphone, a pop filter is used. A pop filter is a device that is placed between the microphone and the voice and helps to prevent plosives and mouth noises from being picked up by the microphone.

The placement of the pop filter is crucial for achieving optimal results. It should be positioned about 2-3 inches from the microphone and placed at a slight angle to avoid any reflections from the filter back into the microphone.

In addition to using a pop filter, there are other techniques that can be used to prevent plosives, such as adjusting the microphone’s position, using proper microphone technique, and adjusting the voice actor’s breathing.

Proximity effect and microphone positioning for vocals

The proximity effect is a phenomenon where the bass frequencies of the voice increase as the microphone gets closer to the mouth. This effect can be desirable in some cases, as it can add warmth and richness to the recording. However, it can also result in unwanted boomy or muffled sounds.

Proper microphone positioning is essential for controlling the proximity effect and achieving optimal sound quality. In general, the microphone should be positioned close enough to capture the nuances of the voice but not too close to avoid unwanted sounds.

To achieve proper microphone positioning, voice-over artists can use several techniques, such as the “thumb trick.” The thumb trick involves positioning the thumb between the mouth and the microphone and then placing the microphone at the distance of the thumb.

Additionally, the angle of the microphone can also affect the proximity effect. A microphone positioned directly in front of the mouth will produce more bass frequencies than a microphone positioned at an angle.

Microphone signage and how to speak into a microphone

Microphone signage is a technique used to help voice-over artists maintain proper microphone positioning and technique during recording. Microphone signage includes using visual markers, such as colored tape or stickers, to indicate the proper distance and angle for the microphone.
