AES Digital Audio into a G%

I need to input SDI digital video and AES digital audio into a Dual G5 Mac. I see that BlackMagic will do the digital video part for in and out but it seems to only output digital audio. How can I get AES digital audio into the Mac. Any suggestions would be great.
Thanks

Thanks this is what I was looking for. It looks like I can bring in SDI digital video through the BlackMagic card and AES/EBU digital audio with the Hosa box connected to the digital audio input on the back of the G5.
Thanks

look for a used AJA I/O. firewire connect to your mac SD only supports embedded or AES.
The HD cards do both SD and HD the kona3 has a control panel that you tell it what you want, or FCP tells it what to do. once again embedded or AES. For analog you'll need an A>D D>A converter
Note that although the audio comes in embedded it is still a separate and editable element. also saves on wiring instead of AES 110ohm wire plus video it all comes down 1 wire. of course that means diddley if you're coming from an audio only device

Trying to find a way to inject digital audio into an HDMI path

There are lots of DVI to HDMI connection options out there, but I have yet to see one that allows one to incorporate digital audio into the HDMI path. Given that there are lots of early adopter video-only HDMI components out there that will be looking for a way to inject a digital audio feed into the HDMI path, so that a monitor can play HDMI video and digital audio natively, instead of either opting for analog audio (where it is available) or being stuck with no way to get audio to follow, one would think that there would be a big market for that sort of a device...
This gets a bit trickier with the Mac Mini when one considers that in order to have access to the TOSLINK, you are functionally locked into either using TOSLINK exclusively, or buying a TOSLINK splitter and then downconverting one of the splits to analog.
One would THINK that it would be in Apple's best interest to make a DVI to HDMI adapter available that would have a TOSLINK cable to plug in to inject the digital audio natively, so the whole thing would be seamless... it would be a very Apple sort of way to deal with it... but that doesn't seem to be in the cards at this point.
Any thoughts/suggestions/death threats?

As an aside I had hoped by now Apple as supposedly a seller of multimedia products might have switched to using HDMI as standard. It looks like they eventually might switch to using "DisplayPort".
Anyway, there are converters that will do what you want. Have a look at this as an example
http://www.gefen.com/kvm/dproduct.jsp?prod_id=3570
Before this particular one shipped their pre-launch information (and pictures) said it would support TOS-Link (which is what Macs use) but when it actually became available it was only for SPDIF.
However since then I have come to a realisation that these converters are probably a waste of time anyway. If you are going to connect directly to a TV which has HDMI then using such an adapter is not necessary because the TV itself only has stereo speakers so using a DVI-HDMI cable plus a mini-jack to pair of phono connectors will work as well even if it needs two separate sets of cables. If on the other hand you are going to connect the Mac mini via an AV Receiver, then all such AV Receivers can accept a DVI or HDMI video signal, and a TOS-Link audio signal and then pass the video out to a TV and the audio out to a set of 5.1 speakers. In effect the AV Receiver itself is such a converter.
This latter approach is the one I intend to use.
If you really do want to consider this approach then there are such converters, even ones which do support TOS-Link connections. A bit of Googling will show them up. In the mean time the one listed below
http://www.gefen.com/kvm/dproduct.jsp?prod_id=4298
would do what you want and also includes a 'scaler' to increase the resolution up to 1080p. This one has two HDMI and TOS-Link inputs. With a Mac mini you would use a DVI to HDMI cable and a TOS-Link cable, it would then output via a standard HDMI cable. It even looks a bit like a Mac mini.
However when you look at the price you can see you may as well use a full-blown upscaling AV Receiver like a Onkyo or Denon.

Digital Audio Processor on MDD Motherboard?

Hi,
I have a bare-bones Mirrored Drive Door G4 Power Mac (Case, SuperDrive, Motherboard, Power Supply), and a 667mhz Digital Audio G4 Power Mac. Can I put the processor of the Digital Audio into the MDD, and would there be any benefit to doing so? (at least until I can get something else to put in there).
Any advice would be appreciated, I haven't began to play with these yet, and wanted some opinions first.
Thanks,
Keith

Hi-
No, you can't.
Get yourself a MDD processor. That's all that'll work.

Can I out an Apple cpu G4 933hz into an Apple digital audio?

I know that the cpu will fit but will it operate?
reason for asking is that I wish to put a third party dual cpu upgrade in the 933hz and wish to utilise the 933hz cpu by placing it into an older G4 digital audio.

I just installed my 533 digital audio CPU in a 450MHz cube. It fit amd works. However you need to take into account pin configuration with bus speed and processor speed when swapping cpu's
The 533 ran on a 133MHz system bus while the 450MHz cube was 100MHz. When I installed 533 in the cube the bus speed pin configuration just happen to equal the right setting to run at 100MHz. Great for me! However the jumper positions for the CPU made it run at 400MHz speed instead of 533. I had to remove the 2 jumpers that were there (magnifying glass and nail clippers) and use a rear window defogger repair kit to add the correct jumper setting which brought it up to 600MHz.
In short your 933 running at 133MHz might just end up being 733 running at 66MHz (just an example) I guess I would just try it and see. Make sure you post back any information you glean.

Audio in a digital recorder into FCE4

Want to record an interview using a lapel mike and a digital recorder. Tried an
Olympus which uses a .WMA format, which I couldn't convert to anything acceptable by FCE4.
Can anyone suggest 1 How to convert .WMA or else what type of digital recorder output is usable in FCE4?
thanks

hey there normrosenblatt,
is there a line-out or headphone out on the recorder? if so you should be able to play the audio into GB using a "Basic Track" send to iTunes & import to FCE.
good luck.

Question regarding mic plugged into audio in/optical digital audio in port

So I have this external headset... headphone/mic set combo... I plug the headphone jack in the headphone slot and the mic jack in the audio in/optical digital audio in port slot in the back of my IMAC. I go to my system preferences select "sound" and "line in - Audio line in port". But when recording, it's still recording from the internal mic? How do I just record just from the external mic??? What am I doing wrong? I've read all the other questions regarding how to get the external mics to work, but it's still recording from the internal mic? Help?
Mac OS X (10.4.9)

I never expected APPLE wouldn't make a mac that didn't have a proper mic jack?
It has a proper one, a good one, a professional one, not the toy that comes with most PCs. Apple has used line level analog audio input for years.
From Wikipedia;Line level is a term used to denote the strength of an audio signal used to transmit analog sound information between audio components such as CD and DVD players, TVs, audio amplifiers, and mixing consoles.
In contrast to line level, there are weaker audio signals, such as those from microphones and instrument pickups, and stronger signals, such as those used to drive headphones and loudspeakers. The strength of the various signals does not necessarily correlate with the output voltage of a device; it also depends on the source's output impedance, or the amount of current available to drive different loads.

How to connect a APExpress to a digital audio console

I have a Yamaha M7CL digital audio console that has an Ethernet connection. I want to control the desk wirelessly using the APExpress. I know how to do it with a Linksys or Netgear router. With those I need to plucg into one of the 4 LAN ports. Not the WAN. And it works great. Since the APEx has only one port (LAN or WAN?) How can I make it work. The console has Network settings that can be changed but I think my issue is that the port on the APE is looking for internet. I'm not interested in using this set up to surf the web I only trying to connect the 2 and wirelessly connect with my laptop. With all the different settings I have no idea where to begin. Can anyone give me a clue. Thanks.

Hello steviee7. Welcome to the Apple Discussions!
In order for the AirPort Express Base Station's (AX) Ethernet port to perform as a "LAN" port so that the Yamaha can access the network/Internet, it would need to be reconfigured as one of the following:
For both the 802.11b/g and 802.11n versions of the AX:
o As as relay or remote base station in a Wireless Distribution System (WDS).
For the 802.11n version only:
o As an extender of a wireless network created by another 802.11n AirPort or Time Capsule.
o As a wireless Ethernet bridge (ProxySTA).

Digital Audio output for W series - Alternatives

There's a thread talking about the displayport does not have audio-output. Its true and some people get victimized by ill-trained sales people who think their displayport is standard. There's no literature on Lenovo website warning users about the audio issue either - such thread is closed with the fact that (some) other manufacturers in the same period does have have audio either and Lenovo think they should be in the same boat.
Let's not go into the blamish again, but discuss what we can do with existing options with alternative digital audio out and line-in that the W series really really missed.
We have (1) mini-dock and (2) USB soundcard listed as options
I currently use a USB DAC (digital to analog) system and it do really good in terms of stereo music enjoyment. However my particular system does not have digital manupilated sound like 3-D surround or multi-channel output and not suprisely, laptop USB generally produce greater latency than desktop USB ports.
Besides USB, we have 1394 and express card 34 as expansion options.
What's your setup for digital audio out? Anyone know any internal soundcard that fits the slots of Wireless USB/Turbo memory PCI ports that all W-series have?

Other alternatives include
I know on mackbooks I've seen firewire used as an input for a Weiss Dac if you're into two channel audio. Do any reiceivers take firewire as an input for hometheater? Has anyone tested Firewire outputs on their W series? I'm told that firewire is sometimes preferable to USB, I'm not sure why this would be, can USB support passthrough of DTS encoded signals?
In the case that firewire works and you Do not have a firewire source, maybe something like this would be of value It converts firewire to digital coaxial s/pdif and allows passthrough of DTS and AC3.
http://www.m-audio.com/images/global/manuals/FireWire-Audiophile_Manual.pdf
As I'm into audio the critical thing here (and what you're paying for when you purchase blue-ray, is maintaining the digital information from the disk in an unconverted form. You want a direct bit pass through, and you want as little jitter introduced to the signal as possible. You most certainly don't want the sound card getting in the way, Digtital to Analog converting and then reverse packaging it up and putting it out over the soundcard digital out. My problem is I'm not familiar enough with computer audio to know how exactly the sounds is transmitted from your blue ray drive to the digital interface you've chosen.
Anyone know why USB digital out would not be a prefered method?

Sound Blaster card 'digital out' into my high-end stereo receiver?

BSound Blaster card 'digital out' into my high-end stereo receiver?A I want?to interface my iTunes music library?(all tunes in Apple Lossless file format) to my high-end sound system, using an optical (TOSLink)?cable and a "mini TOSLink adapter" that will plug into the 'digital out' jack on the Sound Blaster card in my Windows XP PC. This configuration will take advantage of the high-end DAC's in my Denon receiver.
I don't care about getting surround sound out of my PC, and I'm not a gamer. I just want hi-fi stereo music from my iTunes library.
Will this work?Can I expect CD-quality sound?
Also, would it be worthwhile to upgrade my model SB394 sound card to a hi-fi SB card like X-Fi Xtreme Audio, or is any sound card as good as any other for simply deli'vering the digital data stream to my Denon receiver?

well, I have two devices that a combo CD player/Tape decks/radio tuner/amp; one has misc input, the other doesn't. Both are analog devices, both are old things I bought at a yard sale.

But I wonder, what considerations do I have to have?
Firstly, is the Aux In on my board analog or digital? I'm assuming if it doesn't say "digital", it's analog; correct?......
secondly, and more importantly; the CD/Tape/Tuner/Amp thing is supposed to be used with 8 ohm speakers and do I have to worry about sending too much current to the soundcard?
specific model of SB card; I'm not sure. It has 2 analog outs, analog in, mic in, digital out and a joystick port; and it came installed on a 200 Dell w/ Win ME
and please, don't try selling me something; I use old crappy hardware and really do not mind doing so.
any help will be appreciated, thanks.
Aux-In is an analog port (4-pin connector/stereo).
Don't connect powered output (= speaker outputs) into soundcard but, if possible, use some low-power connection like Headphones-Out (or if possible then some line-out port).

The Mother of All G4 Digital Audio Project?

Alright, my apologies right from the get-go: I'm new to this user-friendly and intuitive world of Macs. So if this post is long-winded and excessive, please excuse my bad manners and blame it on living in the world of PCs and M$ for far too long.
To start, the one thing I've found that is consistent no matter what computing world I've explored is the cost of upgrading... but first, let me explain a couple of things.
For one -- I'm finished with my PC. I'm fairly computer saavy, and have never bought a pre-built system in my life. My first computer I built in the 8th grade from spare parts and a Pentium 90 chip. Although I've enjoyed my time playing around and working with PCs in the past, I've recently become a father (and my wife is now at home 24/7). Suffice it to say I don't have much time to troubleshoot my PC as often as I use to, and with my wife using the computer more and more, I really would like to be able to offer her something intuitive and easy to use (unfortunately, this usually isn't a common description of anything related to the world of M$ and PCs).
Anyways, her entire extended family has been Mac based for awhile now, and I've grown more and more desirous of owning a Mac at home. Well, about 4 months ago I was given an old G4 Digital Audio for free. This gift, coupled with my increasing frustration with the PC, has lead me to contemplate ditching the PC (selling it off), and trying to fully pimp out the G4 to its maximum capacity. FOR CHEAP.
I realize that a Mac Mini would be pretty cheap and cost effective, or perhaps just selling the G4 and putting that money towards something else (like a Mac laptop) might make more sense... but I'm limited on a couple of fronts.
1) There is the issue of some money having already been invested into this G4.
2) I need to keep costs down, while also retaining the ability to expand (my PC currently has 3 HDDs at a total capacity of 800gb)... and it just doesn't seem feasible with a Mac Mini.
3) I already have the G4 -- and in my wife's eyes, expanding this rig is cheaper than buying a brand new Mac (this point is clearly debatable).
4) We really just need a solid system at home, easy for her to use, while having enough muscle for me to use the Adobe/Macromedia/Final Cut software packages.
So... I'd like to start pushing this G4 to its limits performance wise, while not breaking the bank unnecessarily. I've looked into upgrading the logic board and CPU, maxing out the system memory, purchasing a SATA controller board and new HDDs, and finally springing for a new video card. My question is this:
Can anyone shed some light on upgrade options that would suit my needs, without giving my wife reason to leave me?! For example, when looking to upgrade the G4 to a wireless system, I opted to purchase a Belkin Wireless G (F5D7000) instead of a official Airport card. It works flawlessly, is G compatible, and was only $25. Are there similar options when looking at SATA controller cards (the Sonnet cards are really pricey)? PC133 memory -- should I buy new or look for sticks in older PCs? Buy a pc video card and tweak it to work in a Mac, etc? Should I buy a single cpu upgrade, or spring for the pricey duals (is the performance benefit in OSX and the various design software packages worth it? - I've seen varied reports on this)? 1.6ghz vs. dual 1.4ghz??
Any help in this endeavor to build the Mother of All G4 Digital Audios would be wonderful. I know this post is lengthy, but I needed to vent some frustrations, and ask for a helping hand in this transition from PC to Mac! Thanks to all who've read this beast of a post -- and if anyone has anything to contribute (either suggestions or directions to some relatively cheap upgrades - new or used), it would be greatly appreciated!
Thanks again!

[Solved] Difficulty getting digital audio to play in all applications

This is probably a noobish question...
My motherboard supports digital audio out via S/PDIF cable (optical), as well as standard analog audio. I have a stereo receiver that I've plugged my optical cable into.
When I go to systemsettings > Multimedia > Phonon > Audio Playback, I put the "HDA Intel S/PDIF Digital" device on top and clicked Test. I could hear the test tone (playback source is PCM).
However, if I go to play an MP3 or whatever, I have to go into the settings for each application and tell it to use that particular device. Some applications (such as Firefox) do not have obvious settings for audio playback. Is there a way to solve the problem once and for all (tell the audio system "send everything through the digital device all the time")?
(I read the relevant section of the wiki, but it is focused on getting sound out of your digital device, not making it the default.)
Any other advice or gotchas about using digital audio would also be appreciated.
Thanks!

My .asoundrc looks the same as above. But just for fun, I also tried removing it and restarting alsa, with no change.
I'm testing output by going to systemsettings > Multimedia > Phonon and clicking the Test button with "HDA Intel (AD198x Digital)" selected. Nothing comes out through SPDIF, though it does play through analog (I have two separate pairs of headphones plugged in, one to the analog jack and one to a headphone amp plugged through the digital port) so I can tell which port the audio is coming from).
I've checked the hardware volume, and it appears to be in order. The amp is not reporting any audio signal on the optical port. I tried switching out the cable just to be paranoid, and still nothing. I believe this is a software problem.
Any ideas?

When external speakers are plugged in to headphone jack, sound randomly goes back to internal speakers or digital audio setting, then back again

I have an essentially new MacBook Pro with Lion and all updates applied, and am wondering if this is a hardware or software problem. Essentially with something plugged into the headphone jack, things work as they are supposed to for a while, then the sound will switch back to internal speakers, or sometimes 'digital out' (I can watch it change in the system settings), and then often switch back. It doesn't seem to follow any sort of pattern or be related to any specific application that could be open, and happens with different sources of audio (iTunes, streaming from the web), and different external speakers or headphones plugged in.

Sounds hardware related. If it's brand new, and you're still under warranty I would have it checked out.
I have not experienced this on my computer.
As I understand it, you have analog RCA outputs from an 1/8" to left and right RCA outputs. when you're randomly using the computer, it'll switch to internal speakers, then to digital audio, back to your stereo analog external speakers.
This should not be happening and if it's happening with streaming content (I am unaware of anything that streams in 5.1 digital audio) then this must be something that an apple specialist should look at and consider.
Does this happen with the headphone jack out? when you hold your finger over the headphone jack area does a red beam come out of it *blinking* or just on? This will be a good indicator that your audio hardware is faulty. are you running HDMI out?

Apple TV3 HDMI - DVI jack fine. TV has no DVI digital audio input.

I can buy a converter from HDMI to DVI for video, My TV does not have a digital audio input for the optical cable. I may be able to plug into my sony surround sound amp in to the SA-DC CD in optical port and just play through the surround sound all the time? Which would not give me sound if I used the TVs internal speakers? Or there may be a converter from an optical audio to a R & L DVI Audio Input Jack?

Before you do just note that HDMI is the only supported connection so there will be no guarantee with any converter used. If it does work you will be unable to view protected content, unless your monitor specifies HDCP compliance. Functionality could also cease at any time.
The optical port is for connecting to a receiver, which you would need to do as DVI doesn't carry audio.
