I can't get this test to work. I can't find anything I am doing wrong. Does the length of the file have to be in between a minimum and maximum length to compare 2 files the way you did in this example?

I basically took one of my songs and truncated it to around 30 secs and then coverted it to mp3 and back to wav. I then tried to load the original and the decompressed wav like you have showing in the picture and hit "import". But then nothing happens - no measurment. What am I missing?
Thanks for any help

Tested again, and it works for me - Don't you get a popup?

To Others: Have you had any success importing signal/recordings as wave-files?

I'm having problems with the 1.4.0.4, unhandled exceptions during measurement and some general weirdness too. It may have something to do with using channels 3 or 4 for input/output, but I can't be sure. Also I can't get the S/PDIF loopback to work (EMU shows int/ext clock locked ok), either no signal or on some rare occasions very noisy and weird impulse and FR.

Unhandled exceptions occur when the "Measurement is active" window is on, last line of text: - Validating measurement. These have happened with DS or ASIO.

General weirdness: ASIO control panel button stops working and "Measurement is active" window's caption indicates wrong input if it was changed from the previous setting (eg. input changed from left to right -> caption reads In: Right).

I never got to use the previous versions much, but quickly tried the 1.4.0.2 which seemed to work fine (albeit no support for the 3&4 Ch so can't directly compare).

Code:
System.AccessViolationException: Yritettiin lukea tai kirjoittaa suojattua muistia. Tämä on usein merkki siitä, että toinen muisti on vioittunut.
   kohteessa HOLM.Measure.Measurement.PostMeasureStandard(Measurement* , Int32 , Int32 , ApplicationId , Boolean )
   kohteessa HOLM.HOLMImpulse.AudioHelper.PerformMeasurement(Measurement* meas, String infoString)
   kohteessa HOLM.HOLMImpulse.MainCtrl.Action_MeasStart(Object sender, EventArgs e)
   kohteessa System.Windows.Forms.Control.OnClick(EventArgs e)
   kohteessa System.Windows.Forms.Button.OnClick(EventArgs e)
   kohteessa System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)
   kohteessa System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)
   kohteessa System.Windows.Forms.Control.WndProc(Message& m)
   kohteessa System.Windows.Forms.ButtonBase.WndProc(Message& m)
   kohteessa System.Windows.Forms.Button.WndProc(Message& m)
   kohteessa System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   kohteessa System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   kohteessa System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
That's a part of the message from the unhandled exception if it helps diagnosing.

edit:

Ok, it seems to crash always when the "measurement is active" window's caption reads In: Ch 3, even if the setting in Device&Signal tab was Left. MME/DS/ASIO all do this.

edit2:

Doesn't crash when Output is Ch 3 too, but it doesn't result in a working measurement (looks like just noise).

Is that a screen shot from your computer? You seem to have a nice BeOS color scheme going there.

Just a user error sorry.

Figured out what I was doing wrong. Mismatched samplerates - duh. My master is at 192kHz 24-bit and I forgot that when you convert to mp3 it automatically resamples to 48kHz. So when I decoded the mp3 I ended up with 48kHz 24-bit instead of 192kHz. I redid it with an SRC on the decode and it worked fine.

Maybe if there was a way to add a "mismatched samplerate" and have that dialog pop up. Because when I did it incorrectly it looked more like a crash where the import window just disappeared without any popup.

Nice to hear!

I need to report an error if the samplerates don't match at import.

Default Extend Freq. range?

Would it be possible to extend the frequency range beyond 21kHz? to 30 kHz perhaps?
Working on speakers with ribbon tweeters that easily go that high and would like to test their full capability.

And lower to 10 or 5Hz.
User selectable?
And scalable amplitude scale.

Extending the frequency range and modifying the amplitude scale is already possible from the "options" tab...
