Generally I'd advise measuring using the longest sweep you can tolerate. Leave it set to full-range, and start with 10s. Once you start getting repeatable results in the low-frequency area, you've got the right duration.

Longer sweeps result in a higher SNR for your measurements. Once the signal is far enough above the noise, you get the repeatable results you're after. Knowing what that threshold is depends on your room and your measurement equipment, so experimentation is key.

James: you should check out my video at http://viddler.com/explore/liscio/vid...

It describes how to set up Soundflower to record streaming audio for use with TapeDeck. I hope it helps!

Brian—do you have the latest version of TapeDeck? Make sure you're running 1.3.2, which has a fix for this in MQ and LQ modes. HQ mode is still affected, but as I said before, Apple's working on a fix.

Chris Liscio replied on November 19, 2009 18:06 to the question "Problem with frequency domain differencing" in SuperMegaUltraGroovy:

Ha! This is most certainly a bug.

You are correct—the different sample rates are causing a problem when differencing the records.

I will try to have this fixed in the next 3.2 beta.

Hi Joel,

Could you tell me the details about (a) the duration of the recording, and (b) what quality setting you used?

There's a known issue in Mac OS X 10.6 which causes trouble with HQ recordings of a certain duration. What you've experienced sounds like this problem.

The only workaround I can offer, until I confirm that a fix has been made, is to use MQ mode (which is still CD-quality, compressed similarly to iTunes music purchases) for your long, high-quality recordings.

As I said before: Apple is aware of this, and they are working on a fix. It doesn't just affect TapeDeck—it's a system-wide problem.

Martin, this is very odd. Could you try renaming the files to ensure that the extension is 'aif', and not 'AIF'? Make sure to use the Finder's Get Info window to do it, so you can ensure you get the right extension.

From that screenshot, it appears one of the files doesn't have the .aif extension, though it is recognized as an AIF file by the Finder. Perhaps there's a hidden extension there...

Let me know how it goes.

Hi Harry—you should check out the Getting Started guide I put together, which features the DualPre:

It has some info about the connections you likely wish to make.

Charles, please ensure that (a) you're using copy/paste to enter the name/license key, and (b) you clear out those text fields before you paste the information in. Please email support@tapedeckapp.com if you're still having trouble—thanks! – Chris Liscio, on November 05, 2009 21:06

Sure—in the Finder, you can just right-click a file, and choose 'Compress "MyFile.fume3"' from the popup menu. That'll create a .zip archive you can email to your colleague.

Download the trial, and check it out. The application really sells itself. :)

The biggest feature of TapeDeck is its simplicity. It's a familiar interface, and you're always a single click away from making a new recording. Lots of folks buy it based on that reason alone—the rest is just gravy.

Chris Liscio replied on October 31, 2009 18:06 to the question "how about a HIGHER quality? Broadcast Wave?" in SuperMegaUltraGroovy:

My company-wide policy is generally that only major versions are paid upgrades, with some "slop factor" thrown in to make exceptions for folks that purchased just before a major version ships.

Major versions are x.0 releases, minor are x.1, x.2, and maintenance are x.1.1, x.1.2, ...just to clear up any potential confusion.

So, in short, yes—if you buy TapeDeck 1.2 (and if you bought TapeDeck 1.0), you're getting 1.3 for free.

Because I cannot know the voltage level of all the sound cards on the market (as they do not always report this value, and when they do I don't necessarily trust it), I cannot do such calibrations given only the mV/dB rating of a microphone.

Chris Liscio replied on October 29, 2009 13:51 to the question "In the name of the lord how do i display my results as a 3D waterfall????" in SuperMegaUltraGroovy:

Chris,

You have to ensure that the analysis in the main window is long enough to contain the duration of data that you wish to analyze in the waterfall window.

What that means, is that when you set an analysis window that only contains 100ms of data in the main FuzzMeasure window, asking for 1000ms or 2000ms of waterfall could potentially only create 1 slice (or maybe 2-3).

You can adjust the analysis window by dragging the edges of the shaded region to increase its duration. Alternatively, in the inspector, you can adjust the window start/end/duration manually.

Hope this helps.
