Author Topic: Crackling Sound From Speakers. Heather Gibson Film Handler Posts: 2 From: San Antonio, Texas(TX), US(United States) Registered: Jun 2019 posted 08-31-2019 01:26 AM                     Hello Friends, I am getting crackling noise from my speakers. What could be the reason behind it? Any thoughts or idea?  |  IP: Logged Frank Cox Film God Posts: 2234 From: Melville Saskatchewan Canada Registered: Apr 2011 posted 08-31-2019 01:55 AM                        What speakers? What amplifiers? Every speaker in the auditorium or just one speaker or just one (or two) channels? Continuous crackling? Only when playing a movie? Only when playing non-sync material? Loud crackling that drowns out the desired sound, or you can barely hear the crackling when it's quiet in the auditorium? Just started? Only at certain times of the day or always? Etc.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 08-31-2019 11:06 AM                     Besides a somewhat more refined problem description, it might also help to give some insight in the equipment you're using, like server/projector combination, audio processor, amps and speakers.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-31-2019 11:10 AM                     Photos of the crackling would also help...  |  IP: Logged Heather Gibson Film Handler Posts: 2 From: San Antonio, Texas(TX), US(United States) Registered: Jun 2019 posted 09-02-2019 07:20 AM                     It seems it was basically an OS issue and not directly related to the sound Hardware. Thanks a lot guys.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 09-02-2019 08:17 AM                     Heather I would not expect to receive any technical support from this forum if you don’t take some time to give users some details and, even most importantly, if you cant be bothered to give us more details on what the solution was.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 09-02-2019 10:24 AM                     Maybe Heather isn't even related to an actual cinema and only experienced the crackling on her personal computer setup only? I wouldn't know why anyone would register on film-tech to solve such issues, but maybe she googled 'crackling sound' and somehow found this forum... - Carsten  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 09-02-2019 01:36 PM                        She might be "off the grid" for the holiday weekend.  |  IP: Logged James Westbrook Phenomenal Film Handler Posts: 1133 From: Lubbock, Texas, Usa Registered: Mar 2006 posted 09-02-2019 03:59 PM                     A lot of our current jobs involve IT these days. Some of us who maintain the projection equipment also have to maintain the manager computers in the offices which are Windows 10. However Windows problems are better solved on other sites than this one. This does remind me of an odd "woosh woosh" noise that was heard on playback on the original Lego Movie which I resolved by simply rebooting the Doremi Showvault.  |  IP: Logged Jarod Reddig Jedi Master Film Handler Posts: 513 From: Hays, Ks Registered: Jun 2011 posted 09-02-2019 05:11 PM                     Probably the most vague question ive ever seen asked around these parts. It definitely helps to include as much info as possible.  |  IP: Logged Allen Arin Film Handler Posts: 9 From: New Bern/north carolina,USA Registered: Aug 2019 posted 09-03-2019 12:39 AM                     The crackling sound is mostly caused by having problem in connection,someplace between your amplifier and your speaker driver,causing interference.Connection can be bad in many places addressing the issue is very irritating and it sometimes easy to find or sometimes hard.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 09-03-2019 12:09 PM                        Uh, not necessarily.... a crackle can be caused by any number of things. That's why people are asking for more information.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 09-05-2019 07:54 AM                     Could be caused by: Bad content audio Bad AES connection Problem in the Server Problem in the Audio Processor and or crossover Improper room equalization Bad amplifier channel Bad driver, either high frequency or low frequency (Or mid if applicable) Bad wiring in the system on the channel thats crackling. I probably left out ten other things. But the above are the most common I have run into over the years.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 09-05-2019 08:06 AM                     A bag of chips on a rear seat.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 09-05-2019 11:17 AM                     quote: Carsten Kurz A bag of chips on a rear seat.  |  IP: Logged
