We are very excited to announce that Smaart® Tools single channel module is now available as an in-app purchase in AudioTools.

Smaart Tools was developed by Studio Six Digital in collaboration with Rational Acoustics and is based on the proprietary algorithms, techniques, features & color mapping found in the Smaart^® v.7 acoustic test and measurement software. 

Now, you can have the sophisticated analysis of Smaart® on the iPhone and iPod touch mobile platform.

Smaart® is a registered trademark of Rational Acoustics.

Smaart® Tools will ultimately appear as two modules in our AudioTools app, and will be available as in-app purchases (pricing TBA). The single-channel module is available now, and the dual-channel module will be released at AES NY in October 2011. 

We decided to split Smaart Tools into two modules because not everyone will have dual audio inputs available for the dual-channel features, but everyone has a single microphone and can use the great single-channel features.

Note the the Dual Channel module will not include the features from the Single Channel module. Since there will not be overlapping functionality, they will remain separate purchases.

See our "dB vs. dB" page to understand what the SPL numbers mean, and why they might be different on different modules.

Smaart Tools Single-Channel Module

See our new demo video of Smaart Tools single channel module.

And use this link to access the Help Guide for Smaart Tools single channel.

The single-channel module includes the following features from Smaart® v.7: the RTA Bar graph, RTA Line graph, RTA Bar & FFT graph, and the Spectrograph. On the iPhone and iPod touch, there is an additional graph, the Spectrograph with the RTA Line graph on top of it. Here's a screen shot of that graph from iPhone 4:

All of the RTA banding options available in Smaart® v.7 are available, including log, lin, Octave, 1/3rd, 1/6th, 1/12th, 1/24th and 1/48th Octave modes. 

The decay modes from Smaart® v.7 are also available, and include None, 1, 2, 4, 8, and 16 averages, and the Smaart 1-10 second custom decay settings, as well as Infinite, Fast, and Slow.

The frequency scale can be zoomed down to a single octave, and the dB scale can be zoomed down to 1dB resolution. Double-tap the screen to return to full frequency response, and to auto-scale the dB scale.

Real-time Spectrograph history is saved, just swipe to see sound events that have scrolled off the screen.

Other features include high-contrast mode, variable Spectrograph speed, vertical or horizontal running Spectrograph, Difference mode, Peak Tracking, and FFT Windowing.

All of the standard AudioTools features, such as Save / Recall and the Generator Panel are available. All settings are automatically saved and restored the next time that you run the app.

Because the processor on the iPhone or iPad is not as powerful as a desktop machine, the the number of updates per second is lower than a desktop or laptop machine. iPad2 however, with its faster processor and graphics, runs Smaart Tools at near native desktop speed.

On iPad, split graph mode is available, so that you can put any two graphs on the screen at the same time. Here is a screen shot of the RTA Bar graph and the Spectrograph running on the iPad. (Image smaller than real size).

Smaart Tools Dual-Channel Module

The dual-channel module, which includes the Transfer Function, will require a dual-channel audio input source such as iAudioInterface2, or a compatible USB audio interface on iPad. 

We are still finalizing the dual-channel feature set, but at a minimum we will include the basic transfer function, with both magnitude and phase response plots, the delay finder, and the coherence plot. Please email us with any requests that you would have for features in this module.

We will be updating this page as we get closer to implementing Smaart Tools.
