Question About Calibrating a Room for Surround Mixing W/STP

In the past, I calibrated my system with a home theater calbration DVD played back through VLC which supports multi-channel sound which Apple DVD player does not.
I have moved my studio to a new location and since then I have noticed that when converting a 5.1 mix to stereo that the dialog is a little low in the mix. My thinking is that the center monitor's gain might a little high. Its time to recalibrate the room which brings me to my question.
Is it acceptable to take a pink noise file and simply pan it to each of the outputs in STP and then tweak the monitor gains with my SPL meter to that they all read the same?

Yes with some caveats, depending on whether or not you have a bass managed system.

  • Question about lead in music for podcasting.

    Question about lead in music for podcasting.
    I listen to many other podcasts and there are those which play lead in music with bit of music inside their podcast. The music are songs we all know and enjoy. I have notice that they only play short small clips of these songs and are not royalty free songs.
    My Question would be is there a limit of time which you can play any song with out paying for it and use it in a podcast legally.
    Thanks Mike

    Legally you cannot use copyright music without written permission or a licence from a recognized authority, no matter how short the clip. Many people do this and get away with it (and for full tracks too) and it's debatable how much notice anyone is likely to take, or whether they would be bothered about a short clip. But the legal position is, it's not legal.

  • Question about required workshop classes for OCP

    Im working on finishing up my OCP in a few months. Quick question about the workshop class. Is there a test at the end of the week?
    Also how do most people pay for these classes? They are pretty steep and my company doesnt pay for stuff like this for me. Im paying totally out of my own pocket. Also why is the online class the same amount as the instructor lead class? Its not like im in a room at some building that Oracle has to lease for use or something.

  • Question about calibrating battery

    I have a question about step 5, +Turn off the computer or allow it to sleep for five hours or more+. First off, does it mean let the battery completely run out and turn off the computer, or are we supposed to turn it off. Second, what is the purpose of letting it wait 5 hours before turning it back on? Thanks

    I have a query regarding this, my Macbook went to sleep after draining the power last night (following its first full charge). I plugged it in to recharge at 5:30 this morning and over four hours later, it still hasn't charged, or at least the light is still orange.
    For optimum calibration, does it matter if I use the Macbook while recharging or should it remain off? Should it take over four hours to charge up again?
    Yes, it matters I would let it charge completely until the light changes to green.
    As for the length for it to charge, 4 hours is about right, could be a little longer with a complete drain. Check out [apples battery page|http://www.apple.com/batteries> for more info.

  • Exporting files for Surround mix... fairly urgent!

    hi there... I'm having an advert piece i've written mixed in surround sound which is a first for me. it was all recorded and mixed my end in stereo so I need to know how best to export them for the mix engineer. I am yet to hear from them so I was wandering if anyone could answer the following:
    - Should I send split or interleaved files (assuming 48khz 24 bit .aifs are suitable)?
    - Where there is corrective or creative compression or EQ, should I keep in bounced versions?
    - Where tracks are panned, should I bounce this information or leave centered?
    - Where a track is bussed to a reverb for example, should I send the bus as a separate track, or send the original file wet?
    - Where more than one SFX appears on a track, should I separate them onto separate tracks?
    - I'm assuming I should retain creative volume rides in the bounced information (eg. long fades).
    And is there anything I'm overlooking? I'd be VERY grateful for any input (this has to be sent by tomorrow afternoon!).
    Thanks

    Q: Should I send split or interleaved files (assuming 48khz 24 bit .aifs are suitable)?
    A: Interleaved! see down here.
    Q: Where there is corrective or creative compression or EQ, should I keep in bounced versions?
    A: depends on the media you are going to ship your production.
    Q: Where tracks are panned, should I bounce this information or leave centered?
    A: Be shure your tracks are surround at the first place. then the pans could have been converted. better check in the Automation screen if it does.
    Q: Where a track is bussed to a reverb for example, should I send the bus as a separate track, or send the original file wet?
    A: By my knowledge is this your choice. In the bounce all tracks are mixed to the 5+1 (or the 7+1) channels.
    Q: Where more than one SFX appears on a track, should I separate them onto separate tracks?
    A: Deepends on the effects you have in mind. I see no reason do split it up.
    Other thing: if you are going to bounce be shure it is a PCM 48000 (required for replay on standard dvd player) Interleaved (all channels in one file) put the button Surround on.
    checking your work on a standard video-dvd-player is only possible if you put the audio files in to a video stream with a black image as video. there is no other option unless you have a DVD-A player in your collection. such a player is hard to find these days.
    hope this helps a little,

  • Question about source system copy for BW

    Dear all,
    I have a quick question about copying a source system for BW.
    We have two clients in the source ERP:
    100 Customizing
    200 Testing
    Our BW is only linked to client 200, so when we now delete client 200 and make a copy from 100 to 200, are we then still able to restore the source system connection so that our extraction will work, or will it fail, as in client 100 I have no BW related (except the cross-client-objects like datasource) information, that can be used for a possible restore of this connection.
    What is the procedure in this case?
    Thanks,
    Andreas

    Unfortunately, you will lose your source connection and need to create a new one in R/3.  You can use the same source system name in BW, but check the source system connection after the copy (SM59).  Also, I would "Restore" the source system (in BW, right-click on Source system in RSA1, and click "Restore") to insure the datasources get replicated from R/3 to BW.
    Depending on how much you want your BW and R/3 systems to be in synch, you will need to rebuild all your data providers (cubes/ODS's) from your R/3 system.  This means deleting all the data and running the initializations from scratch.  At the very least, you will need to rebuild the delta queues.
    Curious, if 100 is just for customizing, is there any data in it?  Are you just creating a new blank client 200?

  • Some question about Toshiab reocvery disk for Satellite P300-133

    Hello guys ,
    I got some questions about unpleasant recovery surprises :
    *1)* I just made recovery DVD using Toshiba Recovery Disk Creator and it initially asked for 2 DVDs - but when the first one was done it didn`t require a second blanc DVD . Is it possible all system files of Windows Vista to be written on 1 DVD ?
    *2)* Could I reinstall Windows Vista using the HDD Recovery option ( by pressing F8 ) without using recovery DVD ?
    *3)* Which HDD partitions`ll be formatted ( just system C: or both C: and E: ) using HDD recovery ?
    *4)* What is recovery DVD - Image of the hard drives or Vista installation files ?
    Its pretty bad idea not to include OS on DVD when I have paid for it.
    Thanks for all the problems to Toshiba :(

    1. I think the recovery disk creator means 2 CDs. I have a Portege M700 with Windows Vista and one DVD too. I recovered it and after this I have a clean Vista installation with all drivers and tools from Toshiba. Nothing is missing.
    2. Yes, you can reinstall Vista using the HDD Recovery option when you press F8 at startup. You dont need the recovery DVD but you should create one when your HDD get some errors or something else. If you need a new Recovery DVD, you have pay for one.
    3. The complete HDD and partitions will be formatted, so backup your data first on a DVD, external HDD, USB stick or something else.
    After the reinstallation you have the factory settings.
    4. The recovery DVD is an image of the HDD about the factory settings. If you make a recovery, there are all drivers and tools already installed. Of course on the disk are the installations files of Vista, but you can only use this DVD on your Satellite P300. The disk can not be used on an other Satellite or on a PC.
    When you have more questions, have a look in the user manual. There are a many in formations about the recovery. Its in chapter 3.

  • Thunderbolt / USB3 questions about external backup drives for my new MacBook Pro

    I have a new MacBook Pro retina 13". It has two USB3 and two Thunderbolt2 ports.
    Until now on my iMac I've kept two backups on two WD USB2 drives. I have never had any problems with any of my WD Passport drives. One for Time Machine and one for CCC (a complete bootable clone incrementally created at 3:30 am every day).
    I'd like to get new portable drives for my MBP for these backups going forward and have a few very basic questions, since this is the first time to have a device with a USB3 port, and the first time I even heard about Thunderbolt.
    If I get a USB3 drive and need to use it to restore things on my older iMac, which just has USB2, will it generally connect and run with USB2 at a slower speed? Or would I have to get a drive with both USB2 and USB3 ports?
    Is Thunderbolt just an Apple thing? Or is it a new standard widely used by peripherals now? I just never heard of it before. Is it faster than USB3?
    Is it common for drives to have both Thunderbolt and USB2 connections?
    Are there "hubs" for Thunderbolt like there are for USB? Considering the limited number of ports, I'm wondering the best way to connect 2 external drives. My iMac has 4 USB2 ports on the back, and I connect one drive separate to each of those ports, rather than going through a hub.
    Is USB3 like USB2 in that if you have even 1 USB2 device (e.g. my Logitech headset) connected to a USB3 hub it will slow down everything on that hub to USB2?
    Any recommendations for good, portable backup drives?
    Thanks,
    Doug

    Hi Doug,
    Lets see if we can address some of these:
    If I get a USB3 drive and need to use it to restore things on my older iMac, which just has USB2, will it generally connect and run with USB2 at a slower speed? Or would I have to get a drive with both USB2 and USB3 ports?
    USB3 is "backwards compatible" with USB2 so plugging a USB3 drive into a USB2 port should work, but at USB2 speeds.
    Is it common for drives to have both Thunderbolt and USB2 connections?
    Drives sold as Thunderbolt often (not always) have USB as well, drives sold as USB never (in my experience) have Thunderbolt connections.
    Are there "hubs" for Thunderbolt like there are for USB? Considering the limited number of ports, I'm wondering the best way to connect 2 external drives. My iMac has 4 USB2 ports on the back, and I connect one drive separate to each of those ports, rather than going through a hub.
    Yes there are (but don't expect them to be comparable in price to a USB hub) e.g. see here: http://www.belkin.com/uk/p/P-F4U055/
    Is Thunderbolt just an Apple thing? Or is it a new standard widely used by peripherals now? I just never heard of it before. Is it faster than USB3?
    I'ts an Apple technology (like firewire) and is far from widely used on peripherals.  There ARE Thunderbolt drives etc by companies such as LaCie, WD etc but they are still very expensive (3 or 4x the price of an equivalent sized USB drive).  For some this was a worthwhile expense since Thunderbolt is many times faster than USB2.  But the arrival of USB3 has, in my opinion, changed the landscape.  Yes, Thunderbolt is theoretically faster than USB3 (up to twice as fast) but benchmark tests have shown that in real world situations, the speed difference varies from no difference to Thunderbolt being 25 or 30% faster.  When you take into account that USB3 drives are more common than Thunderbolt and are only a little more expensive than USB2 drives at present, then it's a "no brainer" as far as I am concerned.
    Hope this helps.

  • Question about using 1 SETID for Vendor Master

    Hello everyone,
    I work for a large healthcare system and we are currently in the PeopleSoft training classes and are about to move into the design phase. We are a multi hospital system and are moving everyone to PeopleSoft for our ERP system. My questions is for Supply Chain purposes and hope that someone can help clarify. It is our goal to use 1 vendor master SETID for our entire hospital system. Please see my question below.
    The customer account # for a vendor is currently at the set id. The customer account # is specific to an entity as it identifies where the vendor should ship. How can we have one vendor master (setid) and still allow the correct customer account # to default on the PO (the buyer needs this when calling in an order)?

    On each of these 'dumb terminals' I assume you are looking to access the complete Mac desktop from the central Mac?
    Unfortunately, this can't be done.
    In the past, the setup you describe first was used on mainframes where each end node was a dumb terminal. But it was just text.
    Next came X11 which does mostly what you are asking about, but each end node is basically a full computer in itself. You can remotely log into a central server and get a complete desktop session. This would take using a central computer that is running full X-Windows and then you'd need a PC running Linux, or running Windows and a X-Terminal package like Exceed or a Mac with X11 installed (not sure if you can make the Mac X11 do a full-blown desktop X session.) Note that as the central server, you'd need a computer running an OS with full-blown X-Windows (Linux, Solaris, HP-UX, etc.) -- OS X is UNIX but it doesn't run full X-Windows as its window manager.
    Finally, there is what are called 'thin clients' ... a good example is Sun Microsystems' SunRay... it's enough hardware on the client side to provide display, keyboard and mouse. They boot off a central Sun Solaris server and work just like X-Windows clients. The difference here is that the SunRay unit can't work on its own; it has no disk, and has to boot from the SunRay server.
    And of course there's Windows Terminal Services, which lets you do the same thing with Windows. I think that takes Windows Server edition software on the central computer, and then a regular PC as a client.
    Sounds like your only option is to use Mac minis as you suggest. But then there's no need for a central computer to share, obviously.

  • Question about three-tier architecture for MI

    Hi,
    my question is just for the right understanding. If we speak about three-tier architecture of MI is it right, that the following is meant:
    Client = Presentation Tier
    Middleware = Application Tier/Logic Tier/Business Logic Tier
    Backend = Data Tier
    Thank you and regards,
    Florian

    Hi Florian,
    ICF (Internet Communication Framework) is actually a framework provided by any WebAS. MI makes use of this to receive/send the data from/to the client. It is referred to as ABAP Sync Service in MI terminology. Data comes in the form of HTTP stream. A service is created to provide this functionality. It performs the same job as of the J2EE engine in the earlier versions. The advantage being that an intermediate component between the client & middleware is not necessary anymore, because ICF is part of the WebAS itself.
    You can have a look at this in the sicf transaction, provide the service name as MJC, under this u can see that there are 3 services which MI uses - mi_host, mi_service & mi_mds.
    You can set these parameters in the mobileengine.config file to make the client connect to ABAP Sync Service.
    MobileEngine.Sync.Gateway.Service=/sap/bc/MJC/mi_host
    MI.Sync.ProtocolVersion=251500
    I am in the process of writing a blog, please wait for it.
    Regards,

  • Question about converting to 128kbps for iphone 4

    good day. i was wondering about the 'convert higher bit rate songs to 128kbps' option. i always import my bought cd's in apple lossless, and i guess the music i buy on itunes is 256, so that said i have a few playlists on my 16gb iphone 4 and with all the other stuff on there i still have 9gb's free. would it be worth it to me to convert the songs to 128kbps? will the sound be noticeably worse? i have what are considered really good headphones as well so how will that work out as well? thanks for any help. really wondering about the sound quality in case i end up using more of my memory with pics and apps in the future.

    would it be worth it to me to convert the songs to 128kbps? will the sound be noticeably worse?
    On the iPhone while moving around, sitting in an office, doing stuff, you will likely not notice any difference.
    Perhaps if you sit in a very quiet room and really concentrate on listening, you may notice very minor differnece in quality.
    That option is to save space on the iDevice. If you have plenty, don't use it.
    Note that when you use this option on the Summary screen in iTunes, it only converts when adding to the iPhone.
    Your library is not changed at all.

  • Question about using "dumb terminals" for multiple access points

    For both home and a small busniess setting I have been trying to find info about the possibility of using some form of dumb terminal to provide multimple acces points to a single computer rather than a network of multiple computers.
    I would like to use my LCD TVs, (which have AV and PC inputs) as monitors. I am going to purchase a new mac soon, and it seems it would make sense to spend more on 1 mac with more capability rather than 5 mac-minis (yes, I am trying to have 5 access points, with one one mac).
    I have CAT5 running to all the locations I want to use, I also have airport.
    For the most part I'm expecting only one user at a time, but occasional two. OS X is multi user, but can it support simultaneous users?
    I have searched the discussions/forums and some google searching. Maybe I'm asking the wrong questions. But, I can't imagine that I am the only person who has thought of this.
    If you have any thoughts or suggesting for further searching I would appreciate it. Thanks

  • Question about purchasing apple products for government and militairy personel

    Hi everybody,
    Forgive me if this isn't the right place to start this thread and for my not perfect English language skills :$
    My name is Nick and I live in The Netherlands near Amsterdam.
    In February i'm traveling to NYC for a 7-day citytrip.
    On the internet i read some things about many discounts for militairy personel, including stories from my fellow Dutch soldiers who also got this discount because The Netherlands are allies with the US within the NATO missions in Afghanistan, Iraq and so on.
    I am an active soldier in the Dutch Army.
    In The Netherlands all Apple products are more expensive then the US products ( because of the Dutch taxes ).
    So you understand why i want to buy the Iphone 4S and Ipad 2 in the US.
    Now my question is, can I also get the militairy discount from Apple because I am a NATO allied soldier?
    Or does this rule only apply on US soldiers?
    I hope some one can help me with this issue, because I don't get enough salary to buy Apple products in The Netherlands.
    Thanks in advance,
    with kind regards,
    Nick

    Also realize that the prices in many countries appear higher than US prices because they include taxes. Because sales taxes are different in each state & town/city in the US, the price listed on the website for an iPad is less than what you'd actually be paying - and New York City taxes are not cheap (combined state and city is 8.875%) - so a $499 iPad actually costs $543.29. You might have to pay an import duty when you bring the iPad back, and if you don't you could be charged for it when bringing the iPad into an Apple Store for warranty service - I've been told this is true in the UK, for one.

  • Question about bootable USB installer for Yosemite

    After having wi-fi issues last month, I reinstalled Yosemite (clean install).  I only mention that so that it is understood that I have a pretty good understanding of how this process works. 
    But I am old school and I like physical media for various reasons......not least of which would be in the event I ever have future problems getting online to obtain the download from the app store.  So this evening, I decided to create a USB bootable installer for Yosemite.  I used the following web site, which is quite thorough in explaining the process:
    http://osxdaily.com/2014/10/16/make-os-x-yosemite-boot-install-drive/
    I followed the instructions and successfully created my bootable media using a USB drive.  But because I wanted to put this newly created bootable media to the test (without actually reinstalling anything), I just restarted the computer (command R) to ensure I could boot to the USB installer.  I then clicked on disk utilities and noticed the following folders (and subfolders): 
    Macintosh HD
    ---Macintosh HD
    31.95 GB PNY USB
    --Install OS X Yosemite
    disk 3
    --OS X Install ESD
    disk 4
    --OS X Base System
    Now for my question, does anyone know why I have these multiple folders on the USB drive?  I can understand the first set (Macintosh HD and its subfolder) being my current OS X setup.  And the second setup of folders (31.95 GB PNY USB --Install OS X Yosemite) being the actual USB installer.  But what's up with those last two sets of folders called disk 3--OS X install ESD and disk 4--OX X Base System?  Does anyone know?  Perhaps one of those folder sets under disk 3 or disk 4 would be a hidden partition?  But why both disk 3 and disk 4 folders? 
    I just want to make sure everything is correct here; and that I am good to go with the USB bootable media!  I carefully followed the instructions using the above link to create this USB drive. 

    FYI
    my process just completed:  here is what I see when it is done... (the first you saw in my earlier post.  It took about 15-20 minutes.
    To continue we need to erase the disk at /Volumes/Recovery.
    If you wish to continue type (Y) then press return: y
    Erasing Disk: 0%... 10%... 20%... 30%...100%...
