Hello
I need to get 5.1 surrond channel output outta my HP dv6140tx notebook to connect it to my Phillips HTS5520 home theater. There in no optical cable output from ny notebook so is it possible to install a internal sound card to my notebook, or will a HDMI to coax-optical conector will suffice

Does new mini offer surround sound output?

Earlier mini offered 5.1 surround sound output thru headphone jack. Does new 2014 Mac mini offer surround sound through any of its' outputs, including the headphone jack?

You can get 5.1 out the the HDMI putput.

The headphone jack also includes an optical audio out that supports 5.1. Yo need:

How do you use the color channel output mode in Ultra Key in Premiere Pro CS6?

I'm wondering how the color channel output mode is supposed to be used in the Ultra Key inside of Premiere Pro CS6? I've looked through all the Adobe help items and I don't see any documentation on it.

Before I answer, you might want to read the following article: http://www.photoshopessentials.com/essentials/rgb/
So, basically, if you understood all of that, and maybe already knew all of that, then you can use the color channel to see more deeply into the effect by looking at the details of the image through the lens of the color channel.

Audio surround channel missing - Please advise?

Hi,
I am using DVDSP3 to compile a DVD-V with 5.1, AC3, Apack encoded Dolby Digital Surround sound. The problem is when I playback the session all audio channels playback correctley except the rear left surround, which doesn't playback at all.
I have tried to pin point the problem with the following: -
1. It works fine in Pro Tools where the piece was compiled. I have re-imported the discrete surround stems bounced from Pro Tools back into Pro Tools and all is well. (Audio track can be seen and audio is present)
2. I have encoded the stems with A.Pack and decoded them in A.Pack to see if there was a problem there and that works fine also.
As soon as I bring it into DVDSP, during playback, during simulation and during export DVD image (TS_Video and TS_Audio files) the Rear Surround channel is just not there.
I have tried various combinations of build and format settings in desperation,, in case it was a glitch but with no success.
There are no menus on the DVD, all I have done is configured it to start straight away on playback.
Please can anyone help offer any advise, I need to get this sorted quick and am running out of ideas!
Thanks in anticipation.

Hi Kassey.
Do you mean rear surround as in 6.1 configuration? A.Pack does not provide for inclusion of a rear surround channel. But Compressor 2 and Compressor 3 do include this functionality. Compressor 3 comes with latest FCP Studio2. Unfortunately there is no upgrade path for DVD SP as a standalone application, only as a part of full Studio upgrade.

To devs - feature request: finer channel output control

dunno how easy it would be to implement such a thing but it would be awesome if channel output was a little more flexible
using ffdshow I downmix multitrack audio to pretty much whatever, and I use 4 channels (L,C,R,LFE) which sound waaay better than stereo
5.'s only an option for me when i'm sat directly in front of my pc, which i can't be arsed to do most of the time
being able to to do something similar with games would be pretty cool, and a nice little niche feature

I would use the OS X feedback page.
http://www.apple.com/macosx/feedback/
There is no hack to do this.

I have a FP-1600 and a FP-AO-200 module, 0-20 ma. When I use Field Point Explorer 3.0.1, I can not command any of the channel output current. The current remains in the lowest value 0.0035 A. What is the problem ?

What is the problem ? The communications with the module are OK, because it shows when the current are open or closed.

Jorg,
I noticed that you claimed to be using the module in 0-20mA mode, yet the reading you are seeing is 3.5mA. This is the minimum value (with overranging) when the module is set to 4-20mA mode. My guess is that your module is defaulting back to 4-20mA mode, but your IAK file still thinks the module is in 0-20mA mode. You can verify this by using the find devices button in FieldPoint Explorer and then trying to write to the channel.
To fix this problem, you should use the snapshot feature to change the default power-up mode for that channel.

Surround Channel Order

Is there a standard for surround channel order. Adobe use L, R, SL, SR, C, LFE and Dolby use L, C, R, SL, SR, LFE. A lot of confusion can occur when interfacing the two!
Richard Knight

Unfortunately there seems to be more than one standard. See this article. I tried to find something difinitive on the Dolby site and my search skills seemed to have failed me. All I could find was this Dolby 5.1 FAQ http://www.dolby.com/uploadedFiles/Assets/US/Doc/Professional/42_DDFAQ.pdf
While trying to find the "right" answer for this question, I ran across this page. Kind of cool. I imagine that video people could do a better job visually with this. Might be a fun contest one of these days.

Two digital channel output question

Hi, everyone
I need some helps on design two digital channel output
In brief, I want to use a PCI-6731 output with BNC2110. Two digital
output channel will be used, e.g. Dev1/port0/line0:1. I hope line0 could
output a steady finite samples in frequency f1 (e.g. 10kHz), and total
number of samples like N1 (e.g. 1E6); in the mean time, I hope line1
could output finite samples in frequency f2 = f1/M (e.g. 2kHz), and
number of samples like N2 = N1/M (e.g. 2E5). In another words, I expect
line0 and line1 output same time length samples sequence with different
frequency and also different number. Please note that parameter should
be expected to be controllable, and sometime f2 and N2 are not exactly
integer (then we need take round value).
Thanks for your help in advance.
Solved!
Go to Solution.

Attached is a vi that does what you want, I think. It used two digital outputs clocked by one of the counters. The digital outputs are fed waveforms that are generated by making two frequencies with an integer ratio. You can change the part of the code that generates the waveforms as you wish, and use the rest to do the output.

Right channel output is very weak through headphones

I use my iPod touch when I workout. I have a pair of Bose headphones connected and I have noticed over the past few days that the right channel output when playing songs on the iPod is extremely weak.

- If it works with other headphones the try inserting/removing the plug a dozen times or so. Also try cleaning out/blowing out the headphone jack
- Next Try the standard fixes to rule out a software problem.
- Reset. Nothing was lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory settings/new iPod.
If still problem that points to a problem with the headophone jack.

NI Datalogger (USB-6009)- How do I get all the channels output

How can I get all the channels output to the file? Is it possible to append data blocks into one data file?

Hi,
If you are performing a multiple channel acquisition, the easiest way to write all of your data to a file and have new data appended to that same file will be to use the "Write to LabVIEW Measurement File" Express VI. This VI is located on the Functions>>Output Palette.
If you put one of these on the block diagram, a dialog box will appear with options including an "append to file" option. This Express VI also allows to configure how your channels are saved in the file and the LabVIEW Measurement File can be opened in Microsoft Excel.
There are some other vi's for writing data to a file on the Funcions>>All Functions>>File I/O palette. The "Write to Spreadsheet File.vi" on this palette will work for your application as well. There is an "append to file" input in which you will have to wire in a "true" constant to append your data.
I hope you find this information helpful.

Hal L.

Altiverb surround channels crackling?

Anyone experienced this? I'm working on a very dense 5.1 mix, bought Altiverb to use as a 5.1 reverb, and unfortunately the rear speakers have an obnoxious crackling in them. I've tried soloing only the tracks that are running to this reverb, which cuts the system performance meter to about 70%, well below peaking, have set the buffer to 1024 samples, etc., but this thing won't stop popping and sputtering. Anybody have any advice?

Surround/Multi-channel output

Is there any way to use the Java Sound API (without any extensions/plugings etc) to play audio on a surround-system (e.g., a 5.1 capable soundcard)? If not, are there any Java API that provides this feature?

You can play a sound in a surround-system. However, Java Sound API has some restrictions.
1, It does not play multi-channel format.
2, It does not support speaker channel assignment. That means you can not choose a certain speaker channel to play.
So overall, it can play a sound format which is either one or two channels in a multi-channel system.

Multi-Channel output audio from Quick Time (or iTunes)

Hello all,
I am trying to get multi-channel AC3 audio output from QT and can only get two channel stereo. I have seen lots of related posts but can't quite get it.
I am trying to configure a Mac Mini to output properly via the TOS link port to my audio system. I get surround sound fine playing a DVD but not when playing a .m4v file that does give me surround sound when played on my Apple TV.
Should this be possible?

I appreciate the link Brent! I also had someone point me here http://fplanque.com/dev/mac/ac3-ac-3-5-1-surrond-sound-apple-mac-osx and all is good now.
Thanks!

Logic Pro X 5.1 surround HDMI output

It seems that Logic Pro X (all Logic versions for that matter) cannot use HDMI output for 5.1 surround mixing. Yet all the preference settings in Logic, in Apple Sound and in Midi/Audio Interface utility seem to indicate that it should be possible.
Has anyone ever had any success ??
If not, what is the best alternative ?
I have an Impact Twin that can have 8 optical outputs going to a DAC then to a 6-8 channel amplifier or 6-8 amplified speakers. Expensive proposition when an HDMI would be so much simpler and cheaper.
Thanks in advance to PanCenter for his comments.

Hello octopi - wanted to answer earlier when I get all hooked up, tested and running, but got caught up in some other business.
In any case, you'll find pretty well all the info you need from this thread. https://discussions.apple.com/thread/3639822
In short, you can get 5.1 out of a Mac by 3 avenues :
1. mini HDMI (Mac) to HDMI (AV amp) - for Mac products since late 2009 - or
2. headphone converted to SPDIF (Mac) to SPDIF (AV amp) - for Mac products a bit before that (2006???).
3. an external sound card, either USB (as early as USB 1.1) or FireWire.
For recent Macs, there is also the Thunderbolt option which doubles as a HDMI.
There are also FireWire to HDMI adapters, but I'm not sure how that would work.
For the soundcard options, you need the right amount of audio outputs - 6, for 5.1 - many are 8, which gets you up to 7.1 And of course, you need amps for all those outputs, or powered speakers. Not a cheap avenue.
For the HDMI or SPDIF avenues, you need an AV amp to do the Digital to Analog Conversion, plus an appropriate wattage distribution, the sub needing much more power than the satellites, etc. So there is lot of processing to do on the fly, and that's why there are no special computer speakers with HDMI or SPDIF inputs - would almost be as expensive as an AV amp.
The HDMI and SPDIF are not equivalents. For one, the SPDIF goes only up to 5.1 whereas HDMI can go to 7.1 (or more?). But more importantly, transfers through SPDIF are downmixed to stereo then upmixed to original format - a point that caused some confusion on the posts. In any case, that will work fine for most DVDs played on the Mac or Movies played through iTunes & Quick time.
But if you want to work with 6 (or more) distinct PCM audio files, like you would if working with Logic Pro or Final Cut, then you need to go the HDMI route.
Btw, all AV amps, even the cheaper ones, are supposed to be able to read PCM - it's mandatory. Check here : http://www.the-home-cinema-guide.com/dolby-ac-3.html#axzz37kwyN8FK
But get an AV amp that can read Blu-Ray which can process up to eight PCM channels in 48kHz/24bit depth.
Hopes that helps. Phil
