Capturing digital audio

i need to be able to capture digital audio via my m-audio delta 2496; audio only no pic obviously; mostly without TC but sometimes with.
FCP is pretty poor at dealing with this sort of thing but it used to manage ... now in FCP 5 it is broken; waited a while for new drivers from m-audio but they are now installed and do not help.
wondering if anyone else out there uses other software to capture digital audio with and without TC ....
R.

hello X,
thanks for the offering but i was looking for someone with experience ...
fwiw, my experience with final cut and audio-only/TC sources is that it is unreliable at best.
perhaps you could be more detailed (if you have experience with this), i don't see how providing a video source will allow capture of DAT TC, for instance; and Soundtrack Pro (which certainly falls into the category of "any audio editing software") sees the M-Audio card but gives me errors when i try to access it. last i recall, however, Soundtrack Pro was only able to capture mono audio, and no TC, and therefor is pretty useless right now.
without TC seems like i my copy of ableton will work; with TC, i'm still looking for someone who has experience problem solving FCP 5 (since there were work arounds in FCP 4) or other ideas for software.
thanks.
R.

Capturing digital audio and editing without rendering?

We have a collection of LDs and VCRs that need to be converted to DVD. For this purpose, I purchased a Canopus ADVC 300 which appears to be working great.
The perfectionist that I am, I'm using Optical Digital Audio to import audio from the LD Player directly into my Mac Pro.
(Interesting note here. While FCE is incapable of importing video from one source and audio from another, QuickTime Player X is very capable. FCE is officially behind the times. There is almost certainly an upgrade in the works.)
I can import the video from the Canopus directly into FCE. The digital audio has to be captured by something else; I'll probably use SoundTrack (the non-Pro version comes with FCE).
The digital tracks are 44.1 kHz 24 bit (integer), but FCE does not have an option for this offering only 48 kHz 32 bit floating point instead.
Q. What do I need to do to be able to use the audio in FCE without rendering?
Additionally, even if I import the movie made with QuickTime Player X, the sound will not play in FCE; the 44.1 kHz difference?
Q2. I plan on buying an AC3-RF Demodulator to decode the 5.1 AC3 audio from LDs which make this audio available. Does anyone know which program I'll need to capture all of the tracks for consequent use in FCE?
cheers,
Gregory

If you have QuickTime Pro, you should be able to open the audio files in QT Player, then export them at the sample rate which matches your FCE Sequence. FWIW, many of my students use CD audio (@44.1kHz) in their FCE projects with success, despite my urging to convert the sample rates so that everything matches. They are, however, working with just a few minutes of audio which is not synched to their video.

Capture dvi and optical digital audio-in through one custom capture preset

How can I create a FCP capture preset that will capture from a digital video to firewire box (grass valley (formerly canopus) advc-hd50) AND the optical audio in port on my desktop mac dual g5?
I have HD dvi video (which has no audio content) and digital audio (or analog for that matter) that i wish to capture in sync then edit in FCP.

if you go to audio/video settings you can duplicate a setup that is close to what you want and edit that setup. under capture presets> audio select whichever input on the mac you wish to use.
consult your documentation with the capture device for the video side. when you have something that works save that as an easy setup (on the summary tab "create easy setup")
I've never used either the optical nor analog in so I can't vouch for it's behavior however it is available as an option
Hopefully your device will somehow pass timecode so edits are repeatable

[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?

10.6.8 Broken Digital Audio Out

After update from 10.6.7, digital sound worked. However, software such as EyeTV began capturing the digital audio port and keeping it. Quitting EyeTV would not release the audio to other programs. Other programs then routed sound to the internal speaker. Only way to fix was to reboot. Then it would happen again. Very frustrating to have to reboot to allow sound to switch between programs.
There are other posts about other audio problems related to 10.6.8.
The unofficial trick is to find appleHDA.kext in /HD/system/library/extensions in Time Machine and restore the version from 10.6.7.
This worked for me, but no guarantees. Be careful doing this and make a backup beforehand.

Same problem here too....
I have also a iMac 27" Mid 2010, Apple told me to install MacOSXUpdCombo10-1.6.8 this morning .... It helped nothing... browsing for weeks and tried and excluded all thinkable errors/options... I hope there comes an answer.
Apple also opted to install the original OSX from the DVD delivered with my Mac. Have not tried that. Such a solution cannot be true or??

And suddenly my captures are audio-less...

I have been digitizing some VHS tapes through an ADVC100 this evening. I've done about 15 tapes without trouble, then suddenly FCE stopped capturing the audio from the tapes. This happened without me quitting FCE or anything. Just stopped. I tried to capture with iMovie and iMovie captured the audio fine but iMovie's capture is quite clunky for my tastes. I trashed FCE's prefs tried different setups. Restarted and still cannot get back to FCE's capturing goodness that I had for the previous 15 tapes. grrrrrrrrr
Idears????

I don't know whether this applies to your situation but occasionally FCE can give the impression that the audio has not been captured when it actually has.
Go to View>Video Out and check that "Canvas Playback" has been selected.

Supplemental digital audio recorder drifts out of sync

Dear All,
I have just purchased a Sony ICD-UX70/UX80 digital audio recorder to use as a back-up emergency audio source and it works very well in capturing stereo digital audio. However, when trying to edit this audio source into my video, the audio keeps "drifting," I assume because of the difference in the frames per second between video and audio. Is there any "quick fix" to keep both audio sources in sync...a "make fit" that will adjust the audio to the space allotted to the video? Any suggestions?
Thanks
Barb

Video runs at 48khz. The unit may record at 44.1khz. If that's the case, you need to resample the audio to match the sequence settings.
Resampling can be done in QT Pro, iTunes, Soundtrack Pro, Peak or any number of audio editing programs.
Good luck,

Number of Digital Audio Channels?

How many channels of uncompressed output audio does the Mac Pro's digital audio output port support?
I need to be able to monitor 5 uncompressed channels from Final Cut Pro or Soundtrack.
Thanks
Rick

I wrote to Kevin McAuliffe about this:
Hi Kevin,
Thanks so much for your article " Surround Sound Mixing in Soundtrack Pro 2"
I know you will get a million questions like this but why don't I have 5.1
selection in Audio Midi Setup. It's there but grayed out. I use the digital
optical output from my Quad 2.5 MHz G5 to my 5.1 Receiver.
What do I need?
He wrote back (edited):
The Optical out on the G5 will do you no good. You will either need an A/V capture card (like the Kona 3, which is expensive @ around $4500), or you can go with a cheaper option, which is the FA-101 FireWire Audio Capture device from Roland, that you can setup to monitor in surround sound. I'm not sure where you are located out of, but if you are looking for a reseller, you can contact Bert Silva @ On The Go Technologies ( [email protected] / 416-669-7979), and he can help you with anything you might need. Thanks.

Unable to capture 2 audio tracks

FCP refuses to capture 2 audio channels?! I have one mic on channel 1 and another mic on channel 2 but FCP captures only 1 mono track eventhough in Clip Setting both channel 1 and 2 are selected. Does anybody know what could be wrong?
Another thing is that when I have captured a clip - it won´t appear automatically in the Browser as it always has done? Now I need to import the Clip from my Project folder. FCP going crazy.

Hi boxpuppy,
iTunes is not able to import some Windows Media Player files. See this article for further information -

Digital Audio not working on Satellite A505 S6012

My digital audio stopped working suddenly. I use HDMI to send the video out of my laptop to my projector. I had been successfully using, for over a year, a digital audio cable in the headphone (SP/DIF) jack to output the sound to my home receiver. The default audio set in the control panel is Realtek Digital Audio.
If I set the output to speakers and plug headphones in the jack, I get sound. If I set the output to Realtek Digital Audio and plug the digital audio cable in, I get no sound. I've tried new cables, changing the input to a different conection on my receiver, reinstalling the Realtek driver, and, as a last resort, completely recovering my laptop to the factory setting. Digital Audio still does not work.
Any suggestions? This is the main way we watch movies in my home.

hi, have you try out srs audio program it nice!
can u help me if u have make for yourself a recovery dvd of S505 S6012 because to mine i didnt do it and it gives me a lot of problems.
if you have please i would like to have it.
thanks....

Is there Digital Audio Output on the Macbook Pro

Yep.

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.

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?
Moderator note; comment removed which contravened forum rules

I'm using MAM-A blank CD-R for digital audio and I would like to know which speed do I set to so I can get the best sound?Thanks Joe

When making new digital audio cd's which burn speed is best used with MAM-A 74min/650mb digital audio CD-R's?Thanks Joe

In theory, the slowest speed should result in the most accurate duplication (best sound). This will take much longer than if you were to use use faster speeds and whether that in practical terms is necessary is debatable. Remember, the quality of the disc will be no better than the source material.
Ciao.
PS: You may wish to experiment by making disks at different speeds and listen to them if can detect difference between them.

I recently (Jan 2012) acquired a MacBook Pro (MBP) running 10.7.4 and an AirPort Express. I also have an old PPC G4 tower (Digital Audio model) running 10.4.11. The OS software on both machines is totally up to date. AirPort Utility on the G4 is 5.4.2

I recently (Jan 2012) acquired a MacBook Pro (MBP) running 10.7.4 and an AirPort Express. I also have an old PPC G4 tower (Digital Audio model) running 10.4.11. The OS software on both machines is totally up to date. AirPort Utility on the G4 is 5.4.2 and on 6.0 on the MBP. I bought a used AirPort card for the G4, I believe it is 802.11b compatible, and the wireless data rate is specified at 11 Mbps. Being a newbie to wireless, it took me many days to get these two machines to link up. This network is not connected to the internet, and there no other networks in the vicinity.
My last problem to solve is the very slow file transfer speeds between the two machines. The transfer time seems to vary depending on which machine I use to initiate the transfer, and which direction the transfer is going. For example: If I initiate the transfer from the G4 and send a 5.4MB file to the MBP it takes 1:32 (min:sec), while the same file going from the MBP to the G4 takes 27 seconds. On the other hand if the transfer is initiated on the MBP, going from the MBP to the G4 takes 2:56, while going from the G4 to the MBP takes 1:59. I realize that these times are not actual wireless transfer times but includes the entire transfer process.
Both machines and the AirPort Express are within a 4-foot radius. Both machines are set to radio channel 2. The AirPort Express is set for 802.11n(802.11b/g compatible) with WPA/WPA2 Personal wireless security.
Any help would be appreciated.

BDAqua,
Thanks for the response.
Apple has used the term "Digital Audio" to identify this machine. System Profiler has the following information:
Machine Name:          Power Mac G4
Machine Model:          PowerMac3,5
CPU Type:          PowerPC G4 (2.1)
Number Of CPUs:          1
CPU Speed:          800 MHz
L2 Cache (per CPU):          256 KB
Memory:          768 MB
Bus Speed:          133 MHz
Boot ROM Version:          4.3.3f2
Serial Number:          XBxxxxxMK9
Sales Order Number:
Yes, I could connect them by ethernet if all I wanted to do was transfer files, but I would like to network them so I could use wireless internet. The machines are not always so close together, I did that to simplify the testing. With the very slow transfer speeds I am reluctant to move ahead with the internet step.
