The other averaging types cause the analyzer to automatically stop after the specified number of averages has been reached. This is normal behavior. You indicated that rebooting the iPod touch 4 fixed the problem. I strongly suspect that you have other apps running in the background that consume memory. The unfortunate…

SignalSuite currently requires signal amplitudes to be specified relative to the full scale output level. The full scale level will be dependent on the selected audio output route (e.g. headphone output, or line-level output via the dock connector). Once you know the full-scale output of your particular device, then you'll…

An update was submitted to Apple last week. It should be available for download soon.

An update to SignalSuite has now been submitted to Apple for review.

We are aware of SignalSuite's issues with iOS 4. We'll be releasing an update as soon possible.

Hi, Can you provide a higher-level description of what you're trying to accomplish? It feels a little like we might get lost in implementation details that may or may not make sense for what you are trying to do. Phase is a relative quantity. When you produce sound from two loudspeakers, your microphone only detects a…

Hi J√∂rgen, You can certainly measure the frequency response in the sweet spot. You can also look at group delay, which gives the time delay through the system as a function of frequency. Identifying specific reflections will be trickier. One thing you could do is window the impulse response around specific reflections and…

Jeremy, Are you interested in SignalScope on the Mac, or on the iPhone? Since this is the Mac forum, I will suggest that you download SignalScope and give it a try. On the iPhone, you can measure volts with SignalScope Pro, or with SignalScope when you purchase the data acquisition upgrade (via in-app purchase). In either…

This error appears when you do not have an active internet connection, but when In-app Purchases are enabled in the Settings app. SignalScope's option to hide the display in the main tab view does not disable in-app purchases for SignalScope altogether. Still, I can see how this error could be annoying under the…

No. We do not have any plans to develop software for Windows.

It's tough with an iPod touch, because there aren't any dock connector devices currently available that support simultaneous audio input and output (if someone is aware of one, please let us know). The problem with the iPod touch is that the headphone jack is next to the dock connector, so most of the dock connector input…

Thanks, Artemiy. We'll look into it. If you manage to discover a pattern of this kind of behavior, please let us know.

The Alesis ProTrack blocks the headphone output of the iPod touch. Also, it appears that the ProTrack is unable to function as both an input device and an output device at the same time, which means you can't use the ProTrack's headphone output while you are using its microphone. Unfortunately, that means you'll need to…

You might want to check out the Alesis ProTrack solution, which enables you to use your preferred phantom-powered measurement microphone with a 2nd or 3rd generation iPod touch. Ben

Chris, If you use the built-in accelerometer, you will be limited to a 0-50 Hz frequency band. Also, if you are planning to perform highly sensitive vibration analysis, then the mass of the iPhone or iPod touch may not work to your advantage. The built-in accelerometer is not available for input in IOScope. Ben

beejewel, What horizontal (time) scale do you have set for the channel you are trying to export? The amount of data exported depends on the time scale you have selected in the Oscilloscope. Ben

Dan, What type of microphone are you looking for? What do you intend to do with it? Ben

Officially, only headset accessories that were produced under the Made for iPod program are compatible. As we have demonstrated, it is possible to connect other sources, but it is not typically recommended (due to the low-voltage input requirements, the need for proper loading to get the iPhone OS to recognize the input,…

Check out the Alesis ProTrack. It offers phantom power, and you can plug your DBX RTA mic directly into it. No. The headset input is not recommended for what you are trying to do. I suppose it depends on which industry you are talking about, although SMAART has been fairly successful in the pro audio world.…

To develop accessories for the iPhone/iPod dock connector, please join Apple's Made for iPod program. Apple can then provide you with all the official specifications and documentation that you need.

Darren, SignalScope will work with any iPod touch or iPhone model. It will not run on any other iPod. For specifics about iPod touch models and input/output options, please check out the iPhone section of the blog. Ben

SignalScope Pro includes tools for narrowband (FFT) and fractional-octave-band spectral analysis (whole and 1/3-octave), as well as a built-in test signal generator, multi-channel level meter, oscilloscope, and acoustic calibration capability. However, you may be better served by Electroacoustics Toolbox, which includes a…

So, you were successfully analyzing audio from Quicktime in SignalScope Pro, via soundflower, and then at some point it broke? Did you install the various Rogue Amoeba utilities before or after it broke? Ben
-
It should be, but I recommend starting with a lower voltage (< 1 V) and performing a voltage calibration to see what the full-scale input of your hardware is. Yes. AudioFire devices, from Echo Audio, can handle inputs of up to around 8.2 volts peak (~16 Vpp). Alternatively, you could also use probes with built-in…
-
You can test any signal that your hardware will support. In other words, the software is limited by the hardware. So, if you're using the audio I/O built into your Macbook, then that's the hardware that will determine your measurement bandwidth and voltage limits. You certainly can analyze circuit boards with your Macbook,…

So, you're trying to play back some kind of audio in QuickTime Player 7.6.4 and analyze it in SignalScope Pro via Soundflower? Which version of Mac OS X are you running? Is your line output set as the default system output device? Do you have SignalScope Pro set to restore device sample rates? What is the sample rate of…

You can capture the time waveform of a balloon pop (or similar) with single-shot triggering in the oscilloscope tool. However, the FFT analyzer and oscilloscope are independent tools in SignalScope/Pro, so you can't perform frequency analysis directly on a waveform that you captured in the oscilloscope. Also, the FFT…
