loadapp analog audio signal package

Connect your system

This package enables the output of an analog audio signal in loadapp. The package is limited to your account and independent from the sensors.

Utilize the measurement via your phone to test the integration of force sensors into your setup.

All you need is your android device and a cable to plug into your audio-port. The app offers an analog signal that corresponds to the measured force data. This makes prototyping easy and you can quickly verify your ideas without a complex integration of the system.
Technical specs:

• output of total force depending sound signal for up to two insoles/loadpads
• data for force will be output as different levels of loudness (max. 32,000 steps*)
• max. output signal determined by max. force display setting on android
• one of the following frequencies for the tone is selectable: 400 Hz, 1, 5 or 10 kHz

If data acquisition on PC/Mac takes place through audio input use “Line In” input, to avoid automatic level adaptation of sound input, like on most mic inputs. Line is is most commonly offered by extern (USB) sound cards.

* In reality achievable parameters might vary depending on performance of Android device
