Author Topic: Sine wave sweep DCP Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 06-23-2016 01:58 PM                     Has anyone made a DCP test file that will do a sweep test on each audio channel? Once upon a time we had Dolby's Jiffy test that would do a decent job of showing up speaker problems as well as rattles but I don't think such a thing has been properly ported over to DCP yet.  |  IP: Logged Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 06-23-2016 02:31 PM                     Dolby has 7.1 sweeps for each channel on their site. Edit: To be clear 1 DCP that runs swweps through all channels one at a time. Can be used for 5.1 you just don't get sound on the back surrounds.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 06-23-2016 02:41 PM                     I use the "trick-17" test dcp but I don't know where one can find it now. the site I used, free-dcp.net I think, has gone dark.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 06-23-2016 04:55 PM                     There is a DCP of good old Jiffy knocking about, I don't think it's "official". It doesn't have any picture tests, purely audio. IIRC the wow and flutter section is omitted understandably.  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 06-23-2016 06:14 PM                     quote: Dolby has 7.1 sweeps for each channel on their site. ....

Dolby had both 7.1 AND 5.1 sweep DCP's on their site last time I looked.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 06-23-2016 07:25 PM                     GDC servers come with audio test clips on every server. One is just channel ID using pink noise though.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Both ID and PN as well as 1.85 and 2.39 image sizes.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 06-24-2016 09:14 AM                     Steve, did you get my pm?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!
