Since our business has a voiceover record in general, I will tell you the voice-over records first.
The ideal voice-over recordings should be made in quiet, reflection-less rooms with at least 40 cubic meters of iso-booth. The voice control should stand in front of the glass between the control room (monitor room) and the iso-booth room. The glass has a reflective surface of sound waves, but the sound waves reflected by the glass will remain behind the microphone and if you use a condenser microphone, it will not create problems.

In Voice-over recording, it is very important to have a headset in the dubbing artist, but the sound of the headset should not be too light or too low. The volume of the headset should be adjusted so that the voice will hear both the natural sound and the sound from the headset.

There should never be a latency in the sound monitored by the headset. All of the computer systems have a delay in the monitored sound (signal), which is related to the hardware you are using (such as a sound card, mixer, etc.), good sound cards and now most of the digital mixers are close to 0 ms (10 ms) If you cannot prevent the delay, you can give the sound to the headset from the üzerinde aux anız output on the mixer.
