DAF/FAF Aid Pro app for iPhone and iPad

This app helps people who stutter to speak fluently. The DAF/FAF Aid Pro is the first ever implementation of a true chorus effect with up to 10 auditory feedbacks. The DAF/FAF Aid Pro implements the methods DAF (Delayed Auditory Feedback) and FAF (Frequency Altered Feedback) that have been shown to significantly reduce stuttering for most people who stutter.

Other apps or specialized hardware devices claiming to implement the chorus effect only give you one feedback (with altered frequency and delay).

The app works by recording your voice through your headset, applying these methods and playing the modified audio back to you. Internally, the DAF/FAF Aid uses high-quality non-linear audio processing algorithms for generating the modified audio signal.

* DAF stands for "Delayed Auditory Feedback" and means that the recorded audio is played back with a small, configurable delay (40 .. 500 ms).

* FAF means "Frequency Altered Feedback". The pitch of the recorded sounds is shifted up or down by up to 12 halftones (one octave) and then played back through the headset.

* Since version 2.0 the DAF/FAF Aid Pro supports the new "Multi-DAF" feature. Instead of having just one auditory feedback, you can now have up to 10, each with a different delay and pitch adjustment! If you are not interested in the Multi-DAF feature, theres still the base version of the app available, called DAF/FAF Aid (without the "Pro").

Additional features:

* Background operation: this program will continue to run in the background. You may browse the web, write your emails, etc. while enjoying the DAF/FAF support.

* Bluetooth support: If youve got an iPhone, iPod Touch 4th generation (or newer), or iPad 2 (or newer) and a bluetooth headset, you can use that with this application. Please note that the bluetooth transmission causes an additional small delay.

* Configurable left-right balance: Ideal if you want to walk around with both earbuds of your headset plugged in, but prefer to hear the auditory feedback only in one ear.

* Configurable volume boost: makes low noises louder without overdriving loud noises (automatic compression).

* Optional auto-mute: Configure the sensitivity and set a delay between 1 and 60 seconds.

* Optionally enable the 7-band equalizer to have even more customization options.

This app is compatible with the iPhone (starting with the iPhone 3G), iPad and iPod touch (starting with the third generation). Please note that the equalizer and multi-DAF feature need some additional processing power and therefore are not supported on the iPhone 3G. You will need Apple earphones with mic or a bluetooth headset.

If you are happy with this program, please tell your friends about it, or write a positive review on the App Store. If there are any problems, please let me know. I will do what I can to get it working on your device. Customer satisfaction is very important to me.

***** Money back guarantee *****
It is known that the delayed auditory feedback method doesnt help every person who stutters. This has nothing to do with my app. Still, if you are one of the people whom it doesnt help, I will assist you in getting your money back from Apple.
