Using The Vox-01; Quick Stipa - Vox -01 Operating Manual

4. Using the VOX-01

Quick STIPA

The Quick STIPA module is intended to do simple and straightforward STI measurements
using the STIPA test signal. A comprehensive explanation of the STI method is beyond
the scope of this device manual; there are several online and offline resources that provide
guidance and information on doing STI measurements. In this manual, we will briefly
explain how to set up your equipment for measuring the STI. The Quick STIPA module
makes the process as simple as possible.
For any STI measurement, you need a source of the STIPA test signal as well as an STI
analyzer. In your case, the analyzer is your VOX-01. What the signal source is, depends on
what kind of measurement you aim to carry out.
The Embedded Acoustics reference STIPA test signal is included with the VOX-01 (on a USB
flash drive) and can also be downloaded from the SDi website, free of charge. This is a fully
IEC-60268-16 rev.4 compliant test signal, compatible with all STIPA meters that conform
with the standard.

In order to carry out an STI measurement, complete the following steps:
• Power on your VOX-01 and go to Quick STIPA
• Now start playback of the STIPA test signal through the channel or system
which you intend to test. Note that the STI that you will now measure, will
characterize all parts of your transmission path, from playback device up to
the microphone of your VOX-01.
