Matching dialogue is an art. Recording dialogue for film and drama usually requires two, three or more recording chains, which – when final – should sound like one balanced track.
 

Acoustic interference tubes are used to increase the directionality of microphones. Over the last decades, DPA Microphones has extensively researched and improved the interference tube technology to an unprecedented new level of performance.

This article walks through microphone specifications and explains how they are derived and how they apply to DPA Microphones.

A headset mic is practical for several reasons. You just need to choose one that is appropriate for your situation.

No matter whether you are reporting for radio or television, or creating online content, here are ten tips for any creator working in a home environment.

DPA miniature and instrument microphones are all in-phase. Thus, the user should be aware of this when using a transmitter system with reversed polarity.

The binaural recording technique builds on the principle of placing microphones on a human’s head - or an artificial head. The microphones' position is either just outside each ear canal or at the bottom of the ear canal close to the eardrum. When you reproduce the recording and listen with headphones, the image is very much similar to “being there”.

A drum kit is a focus piece in many musical performances. Unfortunately it can be difficult to mic optimally because of its size and complexity.
 

Audio formats have developed over time. Starting with narrow bandwidth mono, moving on to various versions of two-channel stereo and finally to full-band, multi-channel immersive audio. The sound is reproduced in many ways, ranging from personal headphones to multi-channel systems in cinemas or other big venues.

Immersive audio can be described as a group of recording- and reproduction formats that involve more than a basic two-channel stereo.

Stereophonic sound is, in its basic form, recorded in two channels. What defines the stereophonic recording is the fact that the sound pickup in each of the two channels differs from each other. However, merged together, the audio in the two channels creates an image that provides an additional dimension to the perceived sound, as compared to monophonic sound. Stereophonic recording techniques are based on the knowledge of how directional information is perceived by the human hearing system. When reproduced by loudspeakers in a two-channel system, the first arriving and/or the strongest sound provide this directional information to the listener.

The rest of this article explains how to create a variety of stereo set ups, depending on your preferred microphone types or your preferred stereophonic image.

Comb filtering is a well-known problem in audio engineering. When you hear it, you immediately want to get rid of it. As a trained sound engineer, even the slightest hint of comb filtering causes your neck hairs raise.
