IOScope brings 2-channel transfer function analysis to the iPhone

August 27, 2009 in Utilities (E)

[] Payson, Utah - Faber Acoustical, LLC today announced that its new IOScope system analysis tool for iPhone and iPod touch is now available for download on the App Store. With a suitable stereo audio input accessory, IOScope makes the iPhone an extremely powerful tool for measuring audio, acoustic, electric and electroacoustic systems, such as auditoriums, concert halls, loudspeakers, crossover circuits, PA systems, home stereos, and much more. Finally, two-channel transfer function and impulse response analysis comes to the iPhone! Finally, two-channel transfer function and impulse response analysis comes to the iPhone!

With IOScope users can measure frequency response magnitude and phase, coherence, group delay, impulse response, ETC, and correlation. IOScope's built-in signal generator produces specialized excitation signals, including logarithmic frequency sweeps and periodic pseudorandom noise, for getting the highest quality measurements with little or no averaging.

IOScope also turns the iPhone or iPod touch into a platform for data acquisition, storing acquired data in tab-delimited text files, MAT-files, or images for later download to a Mac or PC. Different engineering units, including Volts, Amps, pascals, g's, and ips (inches per second) can be assigned to input channels of the dock connector audio input or the headset input (headset input not available on 1st generation iPod touch devices). Sensitivity calibration can also be performed for any audio input device or input channel.

IMPORTANT NOTE: iPod touch devices require additional external hardware to get audio signals into IOScope. The 1st gen iPod touch requires a dock connector input device (such as the Belkin TuneTalk Stereo or the MacAlly iVoice Pro) to be used with IOScope. All other devices can perform measurements with the headset connector, but using a stereo dock connector input device is recommended for the highest quality measurements. It is possible to use IOScope with an iPhone's built-in microphone, but this is not generally recommended.

Minimum Requirements:
* iPhone or iPod touch 2.2.1 or later

Pricing and Availability:
IOScope is now available for download on the iPhone App Store for $199.99 (USD). External hardware may be required for analog input capability.
