application. In this case you can start the DAF/FAF Assistant and start the sound playback immediately<br />
by simple pressing the assigned shortcut key.<br />
The Actual Delay displays the current delay value computed by the application.<br />
The DAF/FAF Assistant can run in the background or when it is minimized. So you can work in<br />
another application and still have the DAF/FAF sound playback on.<br />
2. Pocket DAF/FAF Assistant<br />
Overview<br />
The Pocket DAF/FAF Assistant is a software application that implements two altered auditory<br />
feedback techniques: Delayed Auditory Feedback (DAF) and Frequency Altered Feedback (FAF) also<br />
called Frequency Shifted Feedback.<br />
Requirements<br />
The software application requires handheld (Pocket PC) computer running Windows Mobile 2003<br />
for Pocket PC operating system.<br />
For better performance the application requires external headphones and microphone (if available).<br />
Pocket PC selection<br />
The software does not use any proprietary feature of any Pocket PC vendor so it is expected that the<br />
software will work on any Pocket PC running Windows Mobile 2003 for Pocket PC. The following<br />
handheld computers were tested and are compatible with the application:<br />
HP iPAQ h5555 (recommended)<br />
HP iPAQ h4155<br />
HP iPAQ h2215<br />
Toshiba Pocket PC e400<br />
Toshiba Pocket PC e800<br />
Artefact would be very grateful if you let them know about any Pocket PC device that is compatible<br />
with the Pocket DAF/FAF Assistant software and is not on this list yet.<br />
Headphones and microphone selection<br />
Most of the currently available Pocket PCs do not have external microphone input. The only<br />
exception is HP iPAQ h5555. This device has input connections for both external headphones and<br />
external microphone.<br />
The following headphones and microphone configurations can be used:<br />
For models that support external microphone (HP iPAQ h5555) use external headset (microphone and<br />
headphones). You can use either a special headset that is designed for iPAQ (see examples below) or<br />
use any standard cell phone headset and purchase a special adaptor (see below). (Recommended)<br />
Use external headphones and internal microphone. Most of the handheld devices have sensitive<br />
internal microphones that are able to pick up your voice quite well.<br />
Use Bluetooth (wireless) headset. The Bluetooth headset allows you greater flexibility because it does<br />
not use any wires but can degrade the sound quality. Please make sure that your Pocket PC supports<br />
Bluetooth connections (most iPAQs do).<br />
Use internal speaker and internal microphone. When using this configuration please set the volume to<br />
low otherwise your microphone will pickup your delayed voice creating echo effect with lots of<br />
distortions<br />
Please note that different Pocket PC devices have different size of headphone jacks. Currently there<br />
are two standards 2.5 mm (cell phone headset standard) and 3.5 mm (computer audio jack standard). It<br />
