Why Audition CC don't show sample rate correctly?

Hi
Using Audition CC on Mac OS X with Mackie 1220, 12-channel premium analog mixer with integrated 24-bit/96kHz Onyx FireWire I/O (Quality is amazing!)
Need to record on mono a horrible old tape recording with voice only to "hero"'s repairing audio and configure the best sample rate for recording.
My preferences Audio Hardware on Audition are:
Device Class: CoreAudio
Default Input: Onyx Firewire (0025)
Default Output: Onyx Firewire (0025)
Clock Source: Device
I/O Buffer size 512 Samples
Sample Rate: 96000 Hz
Question 1: Expert said do not use more than 48000 Hz for recording voice only and use mono. Humans can't listen more than 20000 Hz... well... My recording on 96000 Hz is better than 48000 Hz and I'm not Superman... and can hear better difference with 96000 Hz recording. Don't know why.
Question 2: Why after selecting Audio Hardware preferences to 96000 Hz after recording the File Panel said my track is 48000 Hz Mono 32 (Float)? My hardware can record at 96000 Hz and preferences is set correcty at that Bit Depth then WHY don't appears 96000Hz on File Panel after recording and instead appears 48000Hz?
Question 3: Don't understand the differences of my 24-bit/96kHz Onyx FireWire I/O and 32 bit (Float) of Audition. If I record using 24 Bits (Maximum bit depth of my hardware) why appears 32 bit (Float)? My recording are 24 Bits or 32 Bits?
Thanks :-)

CS6 has a serious issue with saving files correctly. The program is asuming that 48kHz is the maximum you will be using and in my case it saved a 96kHz recording with a 48kHz internal header. The file size is consistent with all my previous 24/96 recordings and it sounds just fine interpreted correctly - but played an octave low in frequency and tempo it really sucks unless you are a Blue Whale..
I can play it "interpreted" as a 192kHz file just fine, and it now sounds 100% right, but I cannot save it correctly. I have yet to find out how to recover because when I use "convert Sample Type" it saves it with the same mistake - the wrong sample rate off by the same ratio again.
It is a program flaw - so at this point you cannot record with sample rates higher than 48kHz in CS6 and depend on your file being OK.
Tom the reason you can tell the difference between sample rates is that your hearing has two dimensions, frequency and timing, I sure hope you can't hear the bats at night but I expect that you can tell a good drummer from a bad drummer. In addition there is also the issue (dimension) of bit-depth - instrument decay and acoustic space occupies the time space between notes and if it is not sampled at the right time and place or rounded off to the nearest digital digit you have a problem.
You all know that some humans have perfect pitch and others dont, this gives you some indication how much we each differ. Some people have even learned to use echolocation; the best know cases being blind people because they are not supposed to be able to find their way and know where they are. You can learn underlying concepts of this little discussed aspect of human hearing here and hit the university libraries for the rest. http://en.wikipedia.org/wiki/Human_echolocationhttp://
SteveG's comment are only true in one of the three dimensions - frequency range. We all hear about the same for starters anyway.
The second dimension, timing, is what provides spatial information. Coarse sampling effects this as well. My most recent experience was when transcribing some old casette tapes - when I experimented with FLAC and WMA lossless I found that they din NOT downsample well. Spatial information was significantly deminished be that aucoustic or studio work. Needless to say this surprised me because I was auming that I could drop the samplerate to 48kHz as soon I was done editing and save a lot of drive space. For now I made some excellent 48kHz/24 bit mp3s (320) because they altered the sound the least.
Now you know some additional reasons why older guys like me who have lost the high end and a lot of decibel as well can still tell the difference:we have good sense of timing.
Anyway - I need to learn how to edit my files to reset the sample frequency header - real fast. I just recorder a fabulous Madrigal group for 2 hours and my files are lost in the vortex.

Why am I getting midi conflict/sample rate errors. GarageBand 10 intel mac

Why am I getting midi conflict sample rate errors with no connected midi device?

Ok, I'll answer this myself. It has nothing much to do with midi devices being in conflict with anything. Nothing much to do with midi devices, as such, in fact. What it seems to be is a slow running system, whether it be processor, or hard disk, or whatever. In fact, when I found the cause of the problem, it was easy to solve.
What I saw a few times throughout this episode, was an inacurate sample rate report, which caused Garageband to run and react slowly, causing stuttering and flutter in audio output, so that noises were produced as the program struggled to handle the data streams it was reading and trying to reproduce and output cohesively. All of that was caused, it seems, by my iMac overworking and getting a bit too hot for comfort, having run all day, and multitasking for a good deal of it. I didn't adjust I/O buffering, or take any of the usual 'advised action' I've read from other users.
I simply saved my work and shut down the machine for an hour or two. When I restarted the machine, all had returned to normal. The lesson is, it seems to me, is minimise, or, stop other tasks the machine is carrying out. Safari, in particular, seems to be a major drain on resources, so work without it running. Shut down all unecessary programs and tasks, and run Garageband alone, when working in it. Garageband is a much tamer beast when it's left alone to do what you ask of it. It's quite a sensitive little soul. :-)

Audition 3 seeing a different sample rate setting than what the device shows

Hi,
I have just installed Adobe Audition 3, along with the 3.01 patch, on a brand new system running Windows 7 64 bit. The mother board is an Asus Sabertooth X58 using Realtek High Definition Audio. The device drivers show that the audio sampling rate for line input is set to 24 bit 192K. I wanted to set it to the maximum that the sound card would allow to test performance and audio quality.
The problem is when I bring up Audition 3 and hit record, I get the message "We do not support recording when your file does not match your hardware sample rate. Your current hardware sample rate is 44100Hz". Clearly this is not the case since the Line In Properties - Advanced tab is displaying "2 channel, 24 bit, 192000 Hz (Studio Quality).
Under Audition's Audio Hardware Setup it shows only one choice for Audio Driver: Audition 3.0 Windows Sound. It also displays Sample Rate: 44100Hz, Clock Source: Internal, Buffer Size: 2048 samples with no way to change these values.
If I click on the Control Panel button I get:
DirectSound Input Ports:
Device Name: Line In (High Definition Audio Device
Audio Channels: 2
Bits per Sample: 16
Anyone know of how I can change these settings to get Audition to agree with the device settings?
Thanks
Dale

I'm afraid that life is nowhere near that simple. The main issue here is that Audition, in common with most audio software, uses a driver system called ASIO to talk to the sound device - this cuts out a lot of the OS and reduces the latency of the system considerably. There are several problems with ASIO though - the first being that it only supports a single device per system (or sometimes multiple identical devices if the manufacturer can make them look like a single device), and with software designed to use this driver, then to use any other driver (like a native Windows one) you have to use a converter stage like ASIO4ALL. This will convert the ASIO streams to WDM, and let you use multiple sound devices - but with increased latency.
It's the second problem that's really going to stuff you though - and that is that quite reasonably, ASIO is limited by its inventors to run only at three sample rates; 44.1k, 48k and 96k. So there's no way you can run at what you think might be a higher quality setting. All settings above even 48k are making your sound device work much harder, and for what? All that happens is that you increase the potential frequency response to way beyond the human hearing range - to no purpose at all. You don't have sources that can produce useful output at these frequencies, and you certainly don't have the means to reproduce them. This has all been well documented and explained before, so I'm not going over all that again. In a nutshell, Nyquist points out that any digital sampling device has a frequency response limited to a maximum of half of the sample rate, so for 48k that gives us a frequency response up to 24kHz - comfortably higher than any adult can hear by quite a long way. Anything you sample and record beyond this by using even 96k is nothing but noise as far as humans are concerned, and unpercievable noise at that.
So what the line input properties tab is saying is, if you have a non-ASIO driver designed to support all potential rates, possible. You don't have an ASIO driver available, because it's a built-in sound device, and anyway you've already pointed out that it's using the Audition Windows driver (a cut-down version of ASIO4ALL, effectively), so a conversion is already taking place. What Realtek refer to as 'High Definition Audio' is no such thing - all on-board sound devices of this nature are of universally low quality, and to improve this you'd need an external device - of which there are many available, usually with dedicated ASIO drivers. But none of them will work with ASIO beyond 96k, simply because the standard doesn't support any higher rates.
If you download and use ASIO4ALL (it's free), then you will get an additional control panel which will show you exactly what your sound device is capable of doing as far as Audition or any other ASIO software is concerned, and this is a useful diagnostic tool anyway, so it's worth doing. You just select this option when installed, instead of the Audition Windows Driver.
I'm sorry to be the bearer of what seems like bad news, but actually, it isn't. You will percieve no quality difference at all running at anything beyond 48k sample rates; all you will be doing is wasting your computer's resources unnecessarily. You waste both processing resources and hard drive space by processing at ridiculously high sample rates, and there are zero returns.

Why flv videos don't show in version 5.3?

I have bought Keynote 09 5,3 few days ago
when I want to show an old presentation (Keynote old version) with flv videos, don't show the images. Only works audio!!! ??

If these are "modern" .flv files that use H.264 video then you'll need a helper app like Perian to play them using QuickTime.

Why does Soundbooth change Premiere Pro sample rate?

I asked this question in the Soundbooth section and nobody had an answer, so please pardon the cross-post. (The Google machine didn't help, either.) When I take a sound track in PPro CS5 and run the Edit in Soundbooth command, how do I prevent Soundbooth CS5 from changing my 44.1k audio to 48k? It does it 100% of the time. I changed the SB preferences to default to 44.1, but it made no difference.
As a result, the Edit and Replace feature is half useless. I can extract the audio, but can't simply save and switch back to PPro, like the marketing literature would have me believe. I have to save as a separate file, choose the 44.1 rate, then manually remove the original audio and insert the file I just saved. Not the end of the world, but not seamless integration, either.

I'm producing material that's destined for Flash output. That's why I need 44.1. This "feature" is especially irritating since SB's preferences even has a setting to default to 44.1, noting in the dialog box that 44.1 is for Flash. Or tell me if I misunderstand something: my videos will become FLV, not SWF. Should I be using 48k for FLV, even though SWF needs 44.1?
Do that on export, then--not during editing.
I'll take your word for it that PPro is doing the conversion, but when I look at the properties of the extracted audio file in SB, it shows that it's 48k.
If you're using Render and Replace (you said Edit and Replace, but I think this is what you're talking about), Premiere is essentially exporting the audio clip or the audio portion of a movie clip at the highest resolution and bit depth that it can. This is so that any editing you do on the audio in Soundbooth is done at higher level of quality. Regardless of the resolution and bit depth of the source audio, Premiere will "uprez" the audio to the highest quality it can, which is 48kHz at 32-bit depth. So it is Premiere that is doing the conversion, but I don't know if I agree with Jeff that this is a bug. If, on the other hand, you're using the Edit Source File command and it's changing the sample/bit rate, that would be a bug.
Incidentally, you didn't mention if these are movie clips or audio clips you're trying to edit. If movie clips, what is the nature of the video?

I'd go for JButton, since that already has much of the functionality needed.
2. Why I can't see those squares when I run this code?Your code was messed up partly by the forum formatting software. Since I could not be bothered trying to correct it and guess what you meant, I have not run the code.
When posting code or code snippets, XML/HTML or input/output, please use the code tags. The code tags help retain the indentation and formatting of the sample. To use the code tags, select the sample and click the CODE Button.
Also, don't use colors to highlight sections of code, use a single or multi-line Java comment instead.

Why all pictures don't show up in the drop zones?

If I import, for example, 4 pictures in a theme that has three drop zones, only one or two pictures will show up when the loop plays and not in the order I have arranged them in the drop zones. Is there a way to sequence through all 4 pictures in each drop zone? Can for instance the loop be made longer than, in my case 0.28 min (5.0 "Memories" theme)?
Thanks in advance for any suggestion.

Len,
What you mean by "You can only load the same number of images into the number of drop zones and expect the theme to function properly."?
Do you mean that I must have the same number of images, (for example 4) for each drop zone? Or,maybe, one image in drop zone 1, 2 images in drop zone 2 etc. for the drop zones to work properly?

Setting Sample Rates in Audition

Hi I am trying to record in Audition and it says my sample rates don't match. I have tried and failed at this so I keep going back to sound booth. Any ideas please?

The problem may be either the settings for your soundcard or more likely the operating systems sound settings if you are using Windows. What soundcard or audio interface are you using?

Why reservation don't show decimal same as process order?

When i create process order 001 its require Mat.A 0.95 ZET, the problem is when see reservation at MB26 its whow order 001 require 1 ZET, Why it's don't show 0.95 as process order require?
Information: Base unit of Mat.A = SET, Unit of issue of Mat.A = ZET, alternative unit is 1 ZET = 1 SET.
In T-code CUNI, decimal places rounding of unit SET = blank, decimal places rounding of unit ZET = 4.
we wouldn't like to set decimal places rounding of unit SET = 4 because, they think its will impact to other material which use unit SET. for this reason we create new unit name "ZET"
Can any senior has solution to make reservation to show decimal when BOM use unit ZET.
or not have the way and back to set Mat.A to user unit SET in BOM and set decimal places rounding of unit SET = 4. but this way they concern about risk.

Dear,
Please try with the customizing settings in t.code " CUNI " ---> Units of Measurement
1.) Take your Units of measure, go to details Screen
2.)There u can see the entry Box with " Decimal Places". Type in u'r option and save.

Pictures don't show in camera roll

Does anyone know why some pictures don't show up in the camera roll after I take a picture? The first time it happened I thought something was wrong and the picture didn't save. I looked in Photos and all the pictures I took were there but not all the pictures are in the camera roll. I haven't moved any photos. It seems to happen if I access the camera directly from the lock screen.

When you access the camera roll from the lock screen, you can only see photos that you took while at the lock screen during that session only. The phone needs to be unlocked first in order to see all your camera roll photos.

The database migration report don't show all the erros at creation time

Hello experts,
I'm using omwb to migrate a sql server database, i realize that at creation of oracle model there are few stored procedures that was not created.. those object doesn't appear in the Errors_and_Warnings_report.htm but in the logs. My question is why the report don't show those objects?
Another question: how to list the objects that the tool was unable to create in the oracle model?
best regards

HHerrera,
Are the stored procedures that were not created, but were not in the in the Errors_and_Warnings report, visible in oracle, i.e. is the text available in Oracle? If so, it would be easy to compile all the objects in your schema and do a select to see which stored procedures were invalid.

Favicons don't show up in Internet Explorer.

I'm just curious why the favicons don't show up in the favourites in Internet Explorer. I have my favourites on the toolbar in folders. When i use Google Chrome it's very easy to see which favourite i want because of the picture next to it. Most of the ones
in Internet Explorer just have an E on them. It makes the browser look a bit tacky and it is the main reason i don't use Internet Explorer much.
They don't get erased in Chrome either when you delete the history.The ones that do work in chrome seem to disappear.

Hi Rayintheuk,
What is the Internet Explorer version you are using ? I will give an explanation for your issue based on the latest version Internet Explorer 11 .
“I'm just curious why the favicons don't show up in the favourites in Internet Explorer.”
Have you checked this setting ?Right click the white part of the bar and you will get this choice.
“I have my favourites on the toolbar in folders. When i use Google Chrome it's very easy to see which favourite i want because of the picture next to it. Most of the ones in Internet Explorer
just have an E on them”
Right click the favorites in the favorites folder and you will get this :
Then it will be shown in the favorites bar. Right click favorites ,you can choose the title widths of the favorites.
“They don't get erased in Chrome either when you delete the history. The ones that do work in chrome seem to disappear”
How did you erase the history ? Erasing the browsing history won`t affect the favorites folder of the Internet Explorer.

Old Sample Rate Display Bug Rears Ugly Head in Logic 7

This bug has been around since Logic 4. I see it now in 7.1.1... (RANT: This drives me absolutely nuts, especially when trying to troubleshoot clocking problems.)
OK, my system = Logic 7, MOTU 424 PCI card connected to old MOTU 2408
1) Boot Logic (autoload song is saved at 48 KHz sampling rate)
2) Select File/Song Settings/Syncronization, then select the Audio tab
3) The sampling rate shown in this window is 44.1 (should say 48, yes?)
4) With that window still visible, change the sample rate to 44.1 (via Audio/Sample Rate menu item). Sample rate display doesn't change (appears correctly).
5) Now change the sample rate back to 48K. Sample rate display now shows 48K, but with about an -8% deviation.
Basically, Logic never shows the 48K sampling rate correctly in this window -- it always displays this deviation.
I can confirm this is a display bug, since a 44.1 file and a 48K file loaded into the same session will play back correctly at their respective sample rates.
Has anyone else seen this?

bump...
Would like to know if anyone else sees the above-described behavior. Cheers!
