Problems with Windows, sample rate above 88.2KHz...

[DaveinEL]

I have a PC running Windows 7 SP1 32-bit running Audition 3 with a M-Audio Audiophile 2496 sound card. I have no problem recording analog signals from the record out of my preamp into the Line-in RCA's of the sound card at 24-bit 96 kHz.
The AP2496 drivers are version 5.10.0.5076
As an experiment I connected the SPDIF-out of my oppo 83SE to the SPDIF-in of the AP2496. In the hardware section of the AP2496 panel I set sync source to external spdif.
The SPDIF locked at 48000 kHz by default. I then played a 24-bit 96 kHz DVD-V with the oppo. The AP2496 SPDIF clock then locked at 96000 kHz, so I stopped the playback and started it over from the beginning.
Audition had been set to record at 24-bit 96 kHz and wouldn't record at this rate until the 96000 kHz reclock and then recorded perfectly.
I looked at the saved audio wave file in spectral analysis and it appears to be 96 kHz.

With this experience, I would say the Windows 7 can record at 24-bit 96000 kHz through the SPDIF-in connection of a sound card.

Wavosaur is ASIO compatible software:.



You may need to install Asio4All driver ...

Ahhh sorry, I was confused. It's the VST Host that allows only MME or DirectX for recording...Wavosaur doesn't specify what it uses. Both progs can use Asio for playback, but this isn't an issue for me.

I appreciate your suggestions all the same. Some new things to explore here.

On VSTHost, when you select ASIO driver into use in "Select Wave Device" dialog, input driver dialog becomes grayed (you may see some previously selected driver there but, that does not mean anything since)... you need to switch the ASIO input/output port(s) through "ASIO Channel Selection..." dialog.

AFAIK, Wavosaur uses ASIO for I/O when ASIO selected.

After reading my previous post, I noticed I refer to 48000 kHz and 96000 kHz. We're not there yet. I meant 48 kHz and 96 kHz (48000 Hz and 96000 Hz).

I have recently acquired an ESI Juli@ soundcard that will work up to 192 kHz. I will try the experiment of capturing a 192 kHz digital output from my oppo BDP-83SE to the Juli@ SPDIF input using Windows 7 and Audition. It will record through the line-in RCA's at that frequency and I expect the SPDIF to accept the digital input also.
The Juli@ only seems to work with ASIO drivers and recording software that can use them.

Ok, I'll try it, though as yet I haven't been able to record anything with it...just empty files. I have Asio loaded, the engine inputs configured for spdif L and R and can see/hear sound through the MAudio control panel, but nothing on the VSTHost meters.

I tried Wavesaur set to asio but it only writes 16 bit files....same as without asio.

Glenn

edit: Ok, changed the config file in Wavosaur to record 24 bits. Now I'm getting somewhere.

VSTHost is kind of "draw connections" interface so least you need to connect the input and output modules by dragging the orange pin from module to another (or use the chain -button found in module). Nice feature in this software is that you can route signal quite freely. Here's an example where I have signal chain: Input --> Volume control --> EQ --> Output and additionally Spectrum Analyzer and Dynamic Range meter for to monitor the Output:

G'day Dave....

I knew what you meant mate...

My experience to date has not revealed sample rate issues with any of the Audio Edit app's that abound (I have the one you mentioned and a number of others). Sometimes I will get a satisfactory 'lock' at 96Khz and sometimes not, whereas at 88.2KHz and below it will 'lock' reliably. Will be interesting to hear how you go injecting a 24bit 192KHz data stream into S/PDIF on a new card though.

It seems to be a known problem amongst the Pro DAW guys and there is heaps of info to be found when you hunt around for it. The only Windows version that seems to be reliable and reported as such, is WinXP Pro and that is what I have discovered after a lot of heartache.

Mal, in all seriousness having a locked-in OS configuration just to run your DAW is not a bad way to go anyway. Windows XP is a good old workhorse for the job. Once it's happy leave well enough alone and even keep it disconnected from the internet if that's possible so that you don't have to tempt fate by installing a security patch or service pack not to mention not having to run an Anti-Virus program all the time. I'm in the same situation with my relatively ancient Pro Tools LE setup (7.4.2) which is on a bit of a mac "time-capsule": Leopard 10.5.4 - the last OS certified for the DAW and plugins.

Yep, this is the way I'm thinking now too mate. Damn nuisance to say the least but hopefully will have all the niggles ironed out soon.

Still have that other problem though but I will open a new thread to discuss that one....

I recorded 2 sides of an LP at 24-bit 192 kHz with the line-in RCA inputs and then made a DVD-A with the 2 wave files. I connected the oppo BDP-83SE SPDIF-out to the SPDIF-in of my Juli@ sound card. In Windows 7 I changed the source to external sync with the sound card panel. The card went to 48 kHz when connected and as soon as the DVD-A started to play the card went to 192 kHz.
I was able to record in Audacity at 24-bit 192 kHz after selecting SPDIF-input. I listened to the recording from the hard drive and it sounds good.

I think that Windows 7 can record at 192 kHz through the SPDIF-in of a sound card with no problem.

The DVD-A sounds very good. I will have to compare it to a previous 24-bit 96 kHz recording of the same LP. The files are enormous and if I can hear no difference I will record at 96 kHz to keep the size down. Looking at the spectral display, there appears to be nothing above 50 kHz in the left and right channels so you would think that I am recording nothing extra at 192 kHz.

So, I don't think that I have solved your problem, but I have been able to record through the SPDIF-in in Windows 7 above 88.2 kHz.

We've been here before. Can't remember the name of the thread but I posted some traces that proved that on certain records which could not have had anything above 22-25KHz (because mastered from digital tapes) actually showed a great deal of energy was digitized well above that range. It can only have been harmonic distortion generated by the playback system.

Excellent for you Dave but you're right, doesn't help me (and many others) out unfortunately.

I'm putting together a set of samples backed up with a performance summary to attempt to get Avid/M-Audio to become more proactive in helping me get this sorted out. Not very optimistic of the outcome though....

The post title "problems with windows 7" would seem to be incorrect.
It looks like the converter, sound card or sound card drivers are the problem. You could ship the converter from Australia to me in Canada and I could try it out (just joking).
You've tried 2 sound cards already. Has Mytek said which sound card will work with their converter in Windows 7?
You could record 24-bit 192 kHz through the line-in and burn a DVD-A and then try what I did if you have a DVD-A player. If that works then maybe the Mytek is the problem.

Only the drivers, not the hardware. Mal stated early on that the audio hardware chain worked into a Mac and, in a later post, worked under Windows XP, presumably on the same hardware as the failed Windows 7 installation.
