Cell Phones in Studio ?

    Anyone have a problem with cell phones in the Mastering room?

    No sir, I don't like 'em !

    I find the beeping, ringing, and talking quite distracting.

    I ask people to step outside the room to use them.

    And more importantly, the ringing can produce odd interferences in monitoring.

    Main Question:

    Has anyone had any audible cell phone interference actually get recorded during a mastering session?


    p.s. Mikey, is it ok to post identical topics in this and Brad's forum?

    I was curious about that a while back - It seems that although amps pick up the signal post-input, even an unbalanced line only picked it up at around -85dBfs or so when it was right next to the phone.

    "Almost" a non-issue while there is audio playing... Almost... I'm sure certain situations and certain types of phones might have different results.

    Not that I keep my cell phone near my gear when I'm working... :shock:

    It's cool to post in both.

    I've had no problems in my room during mastering, even if the phone is sitting on the D/A converter. Now I've had some clients bring me mixes that had problems when the cell rang but that was to tape.

    i have had off and even (rare but it has happend) unpluged speakers ring out with my cell phone. i would expect it do the same with tape heads though i doubt that there would be any problems with the da ad converters

    It all depends on how well everything is wired and the type of gear used.

  8. Even when I was playing in a few bands, all cell phones were off when it was down to business.

    We use to suggest that our clients use their cell phones outside, away from the mastering equipment, but we no longer offer that suggestion since they were still receiving cell phone calls in the mastering room. I have a couple of clients who spend most of their mastering sessions on their cell phones and are only listening half heartily to what is going on in the mastering room. This is distracting for me and if there is a problem later on with clicks or pops then it is harder to figure out what happened or who is to blame. I personally would not use a cell phone in a recording, mixing or mastering room just to make sure that I was not causing a problem for the engineer. I would like to ban cell phones from the mastering room altogether but many of my clients seem to "need" their cell phones at arms length. I have noticed more and more signs going up in doctor's offices and hospitals about people NOT using cell phones while they are in the office or hospital because it could interfere with their communications or life saving equipment. Maybe they are on to something.

    I guess the era of the cell phone is upon us and judging from the number of people (from pre teen age kids to 80 year olds) who are hooked on cell phones I would say that in the not too distant future most everyone in the US will have a cell phone and you may see infants getting their cell phone number as part of the birthing process <grin>.

    I understand that in some circles people are giving up their POTS (Plain Old Telephone Service) completely in favor of a cell phone as their only phone and many are saying that this maybe the wave of the future. So this whole topic of discussion maybe moot in a couple of years as cell phones become the only phone available for use.

    I wish people would not drive and talk as many people do but that is a WHOLE OTHER TOPIC! and not suited to this forum. Latest sighting of a very dangerous act was my driving on I 71 next to a person with a cell phone in one hand, a map over the steering wheel and a sandwich in the other hand. Not sure what appendage he was using to steer the car. Oh well!

    phones do disturb the flow of a session, but I usually find that the clients know this and refrain from abusing them. If it's out of control, I'll tell them I can't hear what I'm doing and it's taking me longer and costing them more. They usually hang up the phone.

    I get interference from my own phone and some other peoples phones...like a clicking whirring/connecting to the internet type sound in my monitors.

    I don't know if it goes to tape as I have a strict 'no phones in recording room' policy while recording

    I have found that it does go to tape in multi-track. For the longest didn't know what was causing it.

    Cell phones will be soon inplanted in the inner ear at birth, sending the message straight to your brain.

    I've noticed that phones that connect to a "data" network such as Black Berries cause horrible interference in speakers, amps, pickups, anything with a magnetic field. It's ugly and it's loud.

    Because of this, I make cell phones are off before getting to work! C'mon, it's common courtesy!

    Wonder what that kind of interference is doing to us physiologically.

    In my country, cell phone operate at GHz freq, that's freq interact with
    plastic surface (in studio like carpet, foam, etc.), and then sound comes from speaker monitor lost the transient. U can try it. Swith off cell phone while sound playing, listen carefully, and then switch on cell phone, can you hear the different? Have the transient diminished?
