Microphone setup

Where the microphones stand is designed before anybody records, against the room they will be standing in and the voice they will be pointed at.

Built for
room sound competing with speech, microphones placed by habit, plosives caught too late and voices that cannot be balanced separately.
Pre-production consultancy
The short version

What starts working. Sources separated enough to balance independently, a room that can be quietened without hollowing the voice, and a placement written down with its reasoning for whoever sets it up next.

Is this for you? For recordings where room sound or source overlap makes the mix difficult. We start with your files and confirm the setup with you. Not if the only question is which microphone to buy; positions are settled before any purchase.

What leaves your plate. Placement advice, a written setup and checks on the next recording, with equipment recommendations only where they help.

The voice is measured before the stand is placed

How many inputs there are, and what each one is there to give the mix, is settled on the multi-microphone setups page; this one is only about where those microphones physically stand, in the room you record in.

A recording can reveal a placement problem

On one partnership, instrument and teaching arrived too closely mixed. We listened to the files, proposed a likely placement problem and confirmed the setup with the partner before recommending a new arrangement.

Placement changes what can be repaired later

A stronger separation between the intended source and unwanted sound gives post-production more room to work. On that partnership, moving the stands made it possible to reduce the room sound with less damage to the voice.

Starting from the person in the chair

Somebody who projects and somebody who murmurs are two different acoustic problems in the same chair. A lesson that alternates between speaking and playing needs a position that survives both without a hand on a fader. So the design starts from the person and the material in front of them, and the equipment question comes last, if it arrives at all.

Two sources in one room is a geometry problem

Where an instrument and a voice share a space, the first question is never which microphone to buy. It is where each one has to stand so that each source arrives loudest where it is wanted and quietest where it is not. Distance and angle cost nothing and decide almost everything, which is why they are worth an hour of somebody's attention weeks before a shoot day.

From the files to the re-check

The sequence only. Distances belong to the room and the voice, and they are chosen per setup.

Positions somebody can rebuild

What gets decided

Distance, height and angle for every input. What the spare input is doing. Which source is allowed to bleed into which, because some bleed is useful and some is fatal. Whether the room needs something soft in it before moving a microphone is worth doing at all. All of it written down as positions somebody can rebuild next month without ringing anyone.

How a room gets advised on from another country

The files come first and the conversation follows them. Where a space needs looking at, it gets looked at on a video call: what the floor is, what the walls are, where the noise comes in, and which of those can be improved with a rug and a closed door before anything is bought. Advice given to a room nobody has stood in has to be checked, so the first batch of files after a change is listened to specifically for whether the change worked.

What a room contributes whether it is invited to or not

Hard surfaces can add reflections; appliances can add hum. Microphone position changes how much reaches the recording, but room treatment or removing a noise source may also be needed. We listen for the problem before choosing the remedy.

At the bench

The work, demonstrated

Try a decision from the craft: drag, tap or toggle, then read the trade-off.

These are illustrative models; no partner’s results are shown.

Phase. A simple phase model: one sound arriving at two microphones, drawn as two equal sine waves one delay apart, with their sum. Real recordings hold many frequencies, so the model's percentage is not a share of the music lost.

Mic distance. What the distance between a voice and its microphone, from 5 to 70 cm, does to a recording. Start with the microphone and source guidance, then listen in the actual room: distance is a starting point to test.

Still open. A voice and an instrument recorded with one, two, three or five microphones, set against three decisions a mix may want to make, each needing more microphones than the one before. The microphone plan decides how many can stay open; one microphone still allows processing.

  1. Balance the instrument against the voice
  2. Control the room-to-source balance
  3. Change the depth of the recording afterwards
  • One microphone. 0 of 3 decisions still available. Everything arrived already mixed. Whatever the room did to the voice is now part of the voice.
  • Two. 1 of 3 decisions still available. The instrument can be balanced against the speaking. The room is still baked into both.
  • Three. 2 of 3 decisions still available. Separate inputs can give more control over the balance, though each may still contain room sound.
  • Five, the way we plan it. 3 of 3 decisions still available. More control remains after the shoot, if the extra inputs capture useful, distinct signals and their phase relationships are managed.

Room noise became removable once the microphones moved, and nothing in the software had changed.

What changes for you

Sources that arrive separated enough to be balanced independently, a room that can be quietened without taking the body out of the voice, and a placement written down with its reasoning beside it, so the next person to set that room up is not guessing at somebody else's decision.
