WiPrySpectrum is the first 2.4GHz ISM band spectrum analyzer designed specifically for the iPhone, iPod touch, and iPad. It is simple and intuitive to use. It allows you to "Pry" into your WiFi environment to detect and avoid noisy channels. Download WiPry in the App Store and test drive our interface for free.

WiPry-Spectrum will allow you to view which frequencies in the spectrum are already in use or have a high noise floor. Selecting a channel with a low reading will yield increased throughput and lower latency.

For specific frequency measurements, you can use the cursors or the divisions on the screen. To view WiFi channels, click on the plus sign in the top left corner. Then, tap on any of the channel numbers listed. It is also possible to enable specific WiFi guides such as 802.11b, 802.11g, 802.11n -20MHz (2.4GHz only). To change the channel map, go to the menu bar and tap Measure. The option at the bottom of the menu is WiFi guide. This will enable you to manually select a guide. The default is 802.11n - 20MHz.

Yes. Touch and hold the pause / play menu icon and it will change into single shot mode. After the mode has been changed, tap the single shot icon and the next event will be captured and held. To go back to pause / play mode, touch and hold the single shot icon.

If you're using an iPhone / iPod touch, you can use WiPry-Spectrum continuously for approximately five hours.

If you're using an iPad, you can use WiPry-Spectrum continuously for approximately eight hours.

Hello iOS music makers! I'm looking for a spectrum analyzer app that can run as an AUv3 extension. My AU host is Cubasis2. I know there are AU-enabled apps that have spectrum analyzers e.g. Bandshift, but unfortunately with that particular app the analyzer is not visible when the app is running as AU extension. Anyone know of an app that fits the bill? Must work with AUv3 hosts like Cubasis before anyone mentions Auria Pro and fabfilter plugins thx

NuRack includes a spectrum analyzer. Bark filter has a nice spectrum analyzer. Several other apps include spectrum analyzers, like AudioReverb, the Rhino guitar amp, several EQs. You may already own one; look around.

I should add that a very useful feature of the spectrogram in the Mani Consulting Oscilloscope is the Pause button. You can play a transient, then pause the display so you can examine the transient at leisure

like Voxengo Span, FabFilter Pro-Q 3 has a spectrum analyzer with the very useful ability to view a second spectrum from any other instance of Pro-Q 3. pricey though. can any of the dedicated analyzers do this?

Saying that... I maybe being 'anal' anyway as goal is to be able to monitor and adjust the EQ of the guitar tone, pre effects, from the interface to a flat response. Hopefully this will eliminate any colouring

The free SCOPE AU by Mizoshita includes a spectrum analyzer. Be specific here; there are several "scope" apps. Other apps, like BarkFilter and AudioReverb display the spectrum while doing their stuff. NuRack and miRack include spectrum analyzers. So does GarageBand, when you access the effects.

Not sure what you hope to achieve with this though. What with overtones, different pickups/tone settings, etc. Seems like tuning the eq by ear, to get a balanced sound over the range, would be more productive.

Nurack looks like it will do what I want. Although, I probably only need 1% of its capabilities.

The combined spectrum analizer and EQ looks like it will show the dips in certain frequencies and also allow to adjust it simultaneously to give a flat response. Hopefully allowing independent saving in AB per patch.

The Super Meter is a unique way to visualize the three most important measurements of your sound. Loudness (LUFS), dynamics (TrueDyn), and peaks (True Peak). The outer rim displays short-term measurements (3-second time span) for a real-time feel of your music, whereas the inner rim displays integrated measurements (from the beginning of your recording).

The classic LUFS meter will show you the LUFS momentary (400ms), LUFS short term (3s), and LUFS integrated values of your signal.

The LUFS momentary value gives you an instant representation of your material's loudness level, whereas the LUFS integrated value represents your average loudness from the beginning of the recording. The goal is for your LUFS integrated value to settle on your LUFS target value before delivering your material.

The LUFS Histogram represents your music's loudness (LUFS) and short-term dynamics (TrueDyn) over time. It is the best way to compare different parts of your songs and see how their loudness and dynamics evolve and compare to one another. You can also see if your material exceeded your True Peak Max limit with red alert dots.

VU Meters will help you manage your recording levels and avoid overloading, distortion and help you hit your digital converters at their sweet spots by calibrating the meter's 0VU level accordingly. The needle's momentum is set to approximate the human ear response and is well known to be the most 'musical' metering system.

Having access to a real-time frequency analyzer allows you to compare your music to reference material or pinpoint issues such as problematic resonating frequencies or frequency build-ups throughout your mix. Additionally, you can easily zoom in on the left part of the spectrum for better precision at the low frequencies.

Before the LUFS norm got into the picture, levels were calculated using the RMS standard. This is the typical gauge we are all used to because this is what we use on every track of every DAW. It is still very practical and straightforward. Plus, this module allows you to show your True Peak value, customize peak hold time constants or zoom into your dB scale for better precision.

Decibel's Phase Scope will show the correlation between your left and right channels. The module will help you identify mono signals and indicate when your stereo channels are out of phase. It will also visualize your stereo image and show if it leans to one side. As a general rule, the more scattered the dots, the more balanced your signal is. And it looks beautiful.

The Stereo Cloud allows you to visualize where the frequencies of your audio material are located in the stereo field. Bass and high frequencies are respectively represented at the bottom and the top of the module. The X-axis represents the stereo field.

The purpose of the Stereo Cloud is for you to be able to visualize what you hear and feel in a precise and innovative way pleasing to the eye.

Target Validators are the perfect way to know if you have met your targets. Decibel has three targets: your loudness (LUFS) target, which will light up in blue when your material settles at the desired LUFS level, your Loudness Range (LRA), and True Peak Max, which will light up in red if they are exceeded. An absolute must when you want to deliver your material according to draconian specs.
