Whenever I use Easera through an ASIO driver, the system works incredibly slow.
I mean INCREDIBLY slow.

The only thing that resolves this is restarting Easera.
Not even switching to MME or DX.

Is there a resolution to this issue?
Has anyone else encountered this?

I know this is not a soundcard-specific issue, since I tried it with various soundcards, including:
M-Audio 2496, M-Audio FW SOLO, RME Nuendo and BCA-2000.

This is also not a PC-specific issue, since I tried it with 5 different PC systems.

It is near impossible to work with ASIO.

Help... Please... Sad Confused

Hello jonessy,

we have been using the EASERA ASIO at a huge number of computers with a variety of sound cards. ASIO is the prefered driver even.
So we need some more information to to find the reason of your problems.
Please decribe in more detail one measurement equipment,
that means computer(processor,harddisk), sound card (interface, number of input and output channels), sample rate, signal length.
Do you have additional software running during measurements?

If you go to Live and then to the View sheet at left side. Change the refresh rate to 1ms. Which number is diplayed for the "Time needed"?
Did you experiment with the buffer sizes in EASERA and the latencies of the drivers?

Waldemar

Thanks for the reply.

Here's the measurement chain:

Mic: Earthworks QTC1
Preamp: M-Audio FW Solo (integrated on soundcard)
Soundcard: M-Audio FW Solo using latest ASIO driver. Buffer Size: 512 Samples. Two I/O available, using only left channel (mono measurement).

Computer:
Fujitsu Siemens A1650 Laptop, AMD Turion ML-32 (1.8gHz), ATI Radeon M200 video card, Hard-Drives: 80GB 5400RPM (system) and 160GB 7200RPM 8MB Chache (for data connected via USB).


"Time Needed" - running between 36 to 44 ms.

I also forgot to mention that 1st measurement runs fine - the wizard runs a little slow compared to WDM but it works.
The problem starts when I finish my first measurement, and try to perform a second one by going back to the measure tab.
That's when things start to slow-down, and occassionally get stuck.

Thanks again for your help.

Hi Jonathan,

I'm wondering if the USB attached drive might be causing the problem. I've got a big drive I can attach to mine, so I'll give it a try in a little bit.

A couple of questions:
  1. Are you saving the measurements to this drive?
  2. Does the problem go away if you disconnect the drive?
  3. Do you have any SW that came with the FW Solo for recording audio, and does it exhibit the same slowdown?

Hi Bruce,

I don't think it's the drive, since I already tried measuring when it is disconnected.

To your questions:
1. No.
2. No.
3. The only SW that came with the interface I installed was the FW Solo ASIO driver.
I also use Wavelab to record and edit audio on that computer, but the ASIO driver works perfectly fine with that software.

How 'bad' would it be to simply use the WDM driver for performing measurements?

FYI: The same happens with Easera on all our systems.
We purchased 5 licenses, currently 3 of which are installed on 3 different systems:

1. The discussed laptop with FW-Solo
2. A P4 2.8 desktop with RME-Nuendo converters.
3. A P4 2.8 desktop with Audiophile 2496 soundcard.

All systems exhibit the same slowdown when working under ASIO.

I'm starting to think about version compatibility.
I'm not sure, but the problems may have started when we upgraded to v1.05.

OK, good.

Not 'bad' at all. That's why we do all the different drivers, what works best for you should be allowed. Laughing

Do you mean EASERA 1.50? You should certainly be using the current version 1.60. There were some bugs with the ASIO driver for the EASERA Gateway that were solved in version 1.60 that might also improve things for other devices as well. See the version history over here.[/quote]

Does Easera compensate for the significant latency caused by non-ASIO drivers?

I think we upgraded to 1.60, not sure. I will check next week when I'm at the office, and report back.

I really don't mind 'solving' this by using WDM, as long as it does not effect the reliability of our measurements.

Yes, when you do a Dual-FFT type measurement, the loopback will compensate for the changing latencies of each measurement.
