| FAQs |
These are some of the questions most commonly asked about our technology. |
 |
Does it use ultrasound?
No, Intrasonics is encoded using part of the audible frequency band. This ensures wide compatibility with standard audio systems and portable devices.
|
|
Does it upset dogs or other animals?
No, the vast majority of humans and other animals, including dogs, cannot hear any difference between audio with or without our artificial echoes embedded.

|
Exactly what data is in the embedded signals?
Intrasonics systems are typically used to transmit short numerical "trigger" codes rather than transferring large amounts of data, but the size of code and resulting action when the code is received will depend entirely on the application.

|
How much data can be squeezed into the embedded audio signals?
The "bandwidth" available in the concealed audio code-space is not very large. Typically our codes are just numbers but there is sufficient scope for many thousands of customers to each licence their own exclusive range of the available numeric spectrum.

What mobile phones can be used to run the listing apps?
Most commonly available smartphones can run our listening apps, including Apple's iPhone, the RIM Blackberry range, Android phones and most handsets running Symbian.

|
Can we incorporate the technology in our existing iPhone app?
Yes. Brands that have already invested in their own apps, no matter what they actually do, can engage Intrasonics to assist with the integration of our decoding technology into their apps.

|
Does background noise obscure the audio codes?
We have successfully tested our end-to-end technology in many environments, including busy, noisy places such as streets (outdoor PA systems), shopping centres and shops (indoor PA & fixed speakers).

|
Could it work in a live music event?
Yes. Live music and sport events is one of our primary application areas. A great example is a football match with thousands of fans voluntarily running the team's branded iPhone app as the game is played, receiving various promotions and offers from the team's marketing people.

| |
|
Does it work with phones in stand-by mode?
It depends on the handset. Early iPhones (iOS 3 and below) can only run one application at a time and apps can't run in the background so the user has to actually be running the app for it to work. The iPhone 4 and Andoid phones have multi-threading capablities enabling apps to run in the background. We can create apps that can listen for audio codes even when the phone is in stand-by.
