Iphone 4 audio output digital or analog

I have an older treadmill that uses iFit technology (commands from an audio souce control the treadmill). The treadmill will only recognize analog signals which rules my computer out as I'm unable to playback or create analog on my laptop. Wondering if there's any way my iphone 4 could work for that? I don't know if the output is analog or digital?

The cable actually goes from the headphone jack on the phone into the treadmill. So if it's not responding, I can assume it's not due to the phone having digital output if it's analog once it goes through the cable then?

2 different "switchable" audio output (HDMI and analog) with Mac mini

Hello,
I have a 2010 Mac mini that I use as a media center. Its hooked up to my HDTV in the living room via HDMI. I also want to hook up external speakers via the 3.5mm analog jack. These speakers are in the kitchen.
I would like to get my audio through HDMI when I watch TV and be able to get audio output via 3.5mm jack when I just want to listen to music in my iTunes library. I like to control my iTunes library with the Remote app on multiple devices.
Is it possible to switch automaticaly the audio output?
Right now I use my Airport Express to stream music from my Mac mini to the speakers but I think that the Airport isn't really needed since it lies just by my Mac mini. I'm pretty sure the mini can do both.
I've tried to hook the speakers to my Mac mini but first: I hear a "hum" in the speakers (wich I don't hear with the Airport) and second: I can't seem to get the audio out in the speakers.
I've read many posts about the audio midi settings but I can't figure it out...
Any help?
Thanks a lot.

I hit post too early... here's the rest of it.

You can copy an audio stream from one output to another.

Hdmi audio output = digital or pcm?

Couldn't find anything about the Intel's i5 chipset regarding the hdmi audio out except some posted msgs about "can't boot, bad scaling or don't work". I have had the hdmi audio out working & getting the sound out from the LG ips22 monitor; the sound "wasn't that good" & have reverted to the audio out ports.
I've asked LG about the monitor DACs & they said that LG doesn't know as it is whatever the mfg/factory made it(!).
Now, I just wonder if the monitor really have DACs as there isn't any speakers in the monitor, just an audio out. The question to me is whether the Intel chipset is sending sound thru hdmi as digital dsd or analogue pcm & whether the setting can be changed with realtek settings. Blu-ray players has a setting for setting hdmi to digital or pcm. I realize there is a cost thingy so it is hard to believe that the monitor would have DACs unless it also had speakers.
Just a asking for info on what msi know about the i5 & its supporting north, south, east west chips (covering all directions).

For digital audio, if an HDMI device supports audio, it is required to support the baseline format: stereo (uncompressed) PCM. Other formats are optional, with HDMI allowing up to 8 channels of uncompressed audio at sample sizes of 16-bit, 20-bit and 24-bit, with sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz and 192 kHz.[20][51] HDMI also supports any IEC 61937-compliant compressed audio stream, such as Dolby Digital and DTS, and up to 8 channels of one-bit DSD audio (used on Super Audio CDs) at rates up to four times that of Super Audio CD.[51] With version 1.3, HDMI supports lossless compressed audio streams Dolby TrueHD and DTS-HD Master Audio.[51] As with the YCbCr video, device support for audio is optional. Audio Return Channel (ARC) is a feature introduced in the HDMI 1.4 standard.[52] "Return" refers to the case where the audio comes from the TV and can be sent "upstream" to the AV receiver using the HDMI cable connected to the AV receiver.[52] An example given on the HDMI website is that a TV that directly receives a terrestrial/satellite broadcast, or has a video source built in, sends the audio "upstream" to the AV receiver.[52]

IPhone 3Gs audio output

Will any headphones work with the new 3Gs iPhone ?

I would expect any headphones will work with the iPhone for you to hear the music from the iPod - it will be the phone part that might differ and any that have a remote attached to them (e.g. the Apple in-ear phones with remote).

IPhone 4 USB Audio output?

I'd like to know when/if the iPhone 4 will offer USB audio output (digitally). I'd like to use a USB DAC without having to pay ~$600 for a Cypher Labs Algorhythm Solo. I'm not asking for power, as my DAC has its own battery. Is it about money for licensing? The CLAS works...why not a FiiO E17 via the iPad CCK? Android has USB host capability...
Sean

Speculation and rumors are forbidden by the terms of service. The phone doesn't support it. Apple has made no announcement of such a feature or the intent to implement such a feature. Your question can not be answered. There are plenty of cheap docking speakers, alarm clocks, etc. that use audio out from the dock. It's not a matter of money. The system you refer to is expensive because the manufacturer feels they can charge that much and get away with it.

Mini digital/analog audio output

I'm using my Mini for itunes music (AIFF) with my home entertainment system. It's pretty high end and I want my receiver to handle the DAC. Is the HDMI output from the Mini digital? Can I make the output digital?
Should I consider going out the USB to a DAC and then to receiver?
Thanks

Should be HDMI. It's got the highest bandwidth -- it can basically pipe 8 digital audio channels uncompressed -- and you can rely on the DAC in your receiver or pre-amp to do the work. If your setup is good, the DAC in your receiver / pre-amp should also be good.
Others may be able to speak to the USB > DAC question. I'm not an terribly well informed, but USB has got lower bandwidth than HDMI, and is not really tuned for A/V delivery. That said, I've read some good reviews of USB > S-PDIF / Analog Stereo DACs.
Finally, I think that S/PDIF is going to be pretty heavily compressed for anything above simple stereo, so if you're interested in high performance 5:1 or better, it's probably not ideal.

Analog Audio Output Jack for Digital Speakers with same jack configuration

I just purchased my first Mac, a Mac Pro. I can't get sound to my speakers using the analog out jack. With my old PC, there was a setting for "digital output" even though the digital speakers were attached via to the same style jack as the Mac's analog out jack. I've tried going to preferences but don't see a like setting for digital output. Is there a setting to do so and if not, is there an adapter to convert the Mac's digital audio out to the analog jack style?

Do you want digital or analog? Your question seems to imply that you have speakers that accept a digital signal but you also say you want analog...??
Anyway, my Mac Pro (2006 model) has separate analog and optical digital outputs on the back. The pictures on the apple website still show the same thing on the Mac Pro so I'm guessing it's the same. I think only the Mac laptops have the analog/optical digital combo jacks...
The optical digital outputs are the little white squarish ports beneath the rear firewire ports.
The MacPro does not have a SPDIF RCA style output. Maybe that is what you are thinking of from the windoze pc...
You should be able to enable the rear analog line output or the digital outputs from the System Preferences > Sound > Output screen. The front headphone outputs kind of act weird in that they disable the rear line output (if I remember correctly, I never use the front port...).

Combined optical digital audio output/analog line out

Combined optical digital audio output/analog line out minijack on the new Mac Pro support 5.1?

Are you asking if it has that?
http://www.apple.com/mac-pro/specs/
says:
Combined optical digital audio output/analog line out minijack
Which means it does.
On all but the earlier Mac Pro models, this has been standard since the iMac G5.
Mac Pros earlier used SPDIF.
These are now mini-Toslink.

How do i monitor/output digital/analogue audio while editing?

I just switched to the mac pro and am learning FCP. Now i am forced to monitor audio output through my headphones. I want to tie the audio into my studio monitors and also be able to send optical audio in to the mac pro from my main mixer, a Mackie 1404. Do i need a DAC(Benchmark), a optical I/O digital mixer or both or something else? My budget is upt to $1,000, but i would like to spend <$300.
In general, i am trying to figure out how to incorporate analog/digital audio/video in to my new editing system. Before this i was outputting analog video/audio in real time with a Velocity I/O card. I am now, obviously, converting to a new way of outputting my finished product and how to edit and work with the new Mac Pro.
I guess i could also consider using the firewire also, right? I haven't worked with a firewire based audio hardware unit, so any info on that appreciated as well.
Also, is the line out in the back of the Mac Pro mono or stereo? I appear to be getting a mono feed while monitoring clips i've shot.
While researching i might list here some things i have come across. Opinions on these appreciated:

Apple TV2 missing analog audio output for multi-zone system

Found out the hard way that most receivers can't support digital audio in multiple zones (i.e., Zone 2). Since Apple TV2 (ATV2) dispensed with any analog output, if you have a whole-house system that depends on mult-zone to distribute audio to various speakers, you won't be able to use ATV2 to stream music to anything other than Zone 1. The only outputs are HDMI and optical (both digital audio). I think I found a work around (which, of course costs more money) which is a "de-embedding" device from Atlona that takes HDMI in and splits out the audio to analog and passes the HDMI through to the receiver. The analog audio output then lets me connect to the analog in on the receiver so it can stream to all zones. I figure Apple just didn't have enough real estate on the new product to make room for analog, but it's a pain. Hope this helps someone. If anyone knows a better work-around, I'd love to hear it.

I have the same issue with a MacMini I use for music. My solution was to use an inexpensive optical splitter - one feed to the optical input of my receiver and the second to a DAC. Then run standard RCA audio cables from the DAC to the analog Zone 2 inputs.
Here is a link for a DAC
http://www.monoprice.com/products/product.asp?cid=104&cp_id=10423&cs_id=1042302&pid=6884&seq=1&format=2
They should have the splitter as well.

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?

I want to find the digital audio output on my Pavilion vd6853ea notebook

I have spent far too long trying to find where this output is located.
I have a very good Hifi and at the moment am using a USB cable to connect to my DAC.
It looks like there is a realtec digital output somewhere on the notebook as it show up when I go into the playback devices and it tests ok visually.
The 3.5 jack plug is just analog and not a hybrid spdif.
Where is it????????
Please help as I am getting really fed up now!

HI,

Thank you so much for the fast reply.
I thought that may have to be the case.
Can I please ask you a few other questions?
If I want to get a digital audio output not using a HDMI (My DAC doesn't have this input), can I get a good result with something like a Musical Fidelity V link USB to S/Pdif converter or a M2Tech Hiface digital audio interface? Sorry, I cannot make a recommendation on either of those products as I am not familiar with them.
Is it possible to change the sound card with an optical or coaxial output? Your notebook's sound is an integrated solution. It is a chip soldered (integrated) onto the system board. It can't be updated.
Thanks again for the kind help!

Optical/Analog Splitter for Dual Audio Output

Does anyone know if the mini-TOSlink combo jack can simultaneously output both digital and analog signals? If so, has anyone seen a splitter that would let you take advantage of this? I need both output formats to feed into my multi-zone stereo receiver.

I am currently trying to find a solution to what is I think the same problem (receiver only routes analog signals to the additional zones). I haven't been able to find such a cable and have considered these to connect to my multi-zone receiver:
1) I have an old sound usb soundblaster extigy. I have used it in the past as a cheap d/a convertor of sorts as it has both digital input and outputs and works without being hooked up to a computer. If I feed it the airtunes digital signal it outputs simultaneously optical and analog to the receiver. The problem is that the soundblaster does add processing to the signal (volume control and mixing of its other inputs) so although it does sound clean, it almost defeats the purpose of the digital connection. This adds another unit and may not be ideal for you as you would have to buy such a card. Separate D/A convertors would also work but would add even more cost
2) I have considered taking my airtunes apart and tapping into the audio output and adding a second analog output. My warranty is already up but I am afraid the case of the airtunes cannot be opened without it breaking. This option does not fix the same audio distribution problem when I hook up my laptop.
I thought the integrated digital outputs on my macs and airtunes were ingenious till I ran into this problem with my new receiver. Too bad the receiver doesn't have a couple more D/As to route digital signals. With the number in there already for 7.1 channel audio I feel this shouldn't be a problem at least when listening to stereo digital signals.
Sorry for the long post, I will keep looking for a better solution, please post if you do as well!

Digital vs Analog audio meters

hi,
so i'm dumping from final cut to a digital betacam tape and wanted to know if anyone has a rule of thumb when setting your sound levels on the deck compared to the bars and tone's level in final cut.
thanks.

Is this a trick question?
Digital Betacam format supports four channels of 20-bit/48kHz digital audio.
If on the other hand you want to know about outputting digital audio to analog then there are digital levels used to correspond to 0 dB on an analog meter:
1. –12 dBFS: This level is often used for 16-bit audio such as DV audio, and for projects
with compressed dynamic ranges, such as those for television or radio.
2. –18 or –20 dBFS: This level is more common on projects with higher dynamic range,
such as professional post-production workflows using 20- or 24-bit audio.

Can't output Digital Audio in Windows 7 (Macbook Air 2011).

Hi All,
I'm using my MBA 2011 to play 3D Blurays Movies.
The problem is...
> Lion works fine (with HDMI audio) but i can't play 3D Blurays in LION, just 2D Blurays. [I can send...DTS/DOLBY etc etc to my RECEIVER with no problems using the "Moshi mini DP to HDMI adapter".]
> In Windows i can play 3D Blurays (using Power DVD, Corel Win DvD; Arcsoft total media...etc) but i can't use the mini DP digital Audio function as in Lion...(So i think i need a better support driver here....from Intel, Apple or
In the device manager i have an "Intel (R) graphics audio" """device""", but i don't have it listed as a device/extrernal-speaker in Windows interface, i currently have..."just the cirrus logic internal speakersdriver" and the "cirrus logic headphones analog output".
So, anyone know how to output DIGITAL audio using Windows 7 bootcamp?
Best Regards,
Sebastian.

Thanks for your comments. To answer your question theologos, the difference in battery life is huge. I only ran down the full batery in windows and it lasts for a little over 3 hours, depending on how you use it. Fully charged, OS X says I have a little over 7 hours to run although I've never tried to see if it actually gets that much. It seems to last a lot though. I almost never use OS X because I need to do run a lot of windows programs and a lot of statistics in Excel which is disabled by microsoft on office 2011 for mac. Heat levels in windows are acceptable. For general tasks CPU temperature stays below 70 degrees and the laptop is only mildly warm. Even playing starcraft 2 on full settings doesn't cause it to heat up to unomfortable levels.
I realise that graphics switching is disabled in Windows and I hate Apple for it, I know they are doing it on purpose. This is not a question of which OS is better, they both have their merits. However, my guess is this is done via the bootcamp drivers for windows. Since the AMD Radeon 6750 M has graphics switching and is able to perform it with no probs on other non-mac windows laptops I was wondering whether I could remove all the apple graphics drivers and install the default AMD ones. I'm specifically referring to the catalyst driver ackage off the AMD website for this graphics card. If the hardware is there and there are drivers for windows why would it not work on a Mac? If I were to format the system and simply install Windows how would the macbook pro know to keep the integrated graphics disabled? My worry is that if I install the AMD drivers and remove some of the bootcamp ones this might screw up bootcamp if it doesn't recognize them. Anyone tried to do this with any success?
