CLAP
Clap v0.1 – User Guide
Introduction
Hi! First of all thanks for buying Clap. If you are here you will probably want to know more about the settings. I will explain in detail every setting for the o.1 version. Let’s start!
Hidden feature
iphone-6-ring-silent-switch
Before discussing the preferences sections, I wanted to tell you a quick feature that will make your life easier. Clap can occur into false positives. Not a big deal, but in some cases and places this could be tedious. So, when you want to quickly disable Clap, without going into the settings panel, simply put your phone in silent mode. You’ll avoid messages, calls and Clap triggering!
How to use Clap
Clap is very easy to use. The process starts only when you lock your device. After a few seconds, Clap is running and listening. If it detects a loud sound, it checks for some false positives filtering, and then it plays a short alarm. After the alarm, Clap resets after a defined amount of seconds (editable in the preference panel, see below).
Clap completely disables when you unlock the screen, so it doesn’t affect the battery when you are using your iDevice!
Issues
Every bug found by me (or by users) will be added in this article: Clap – Issues. Please check my email at the end of this article to submit a bug.
General Section
1
In the General section you’ll find a simple switch: Enabled. As you can probably figure out by yourself, this switch, when set to OFF, completely disables Clap, until you turn it back ON.
Switches
2
In the Switches section you’ll find another switch: Disable When Charging. This, if set to ON, disables Clap when the iDevice is connected to a power source. When you pull off the AC, Clap starts working again.
Microphone
3
OK; we are now entering some more-advanced features. In the Microphone section, you will find three input field and a button: Trigger Value, Mic Update Interval and Reset Interval and Reset this section to default.
The first input field, Trigger Value, sets the minimum low pass amount to trigger the alarm. In simple words, this is the minimum sound peak that will trigger the alarm. The default value is 865 and it is the best value, in my opinion. Remember: the lower this value is, the lower the trigger sound will be. It can have values from 500 to 1000. If you use a value out of this range, the default value will be used by Clap.
The second input field, Mic Update Interval, sets the time to wait between the listening. The default value is 5000. It can have values from 1000 to 5000. If you use a value out of this range, the default value will be used by Clap. Note that a value closer to 1000 will make the detection easier, but will consume more battery.
The third and last input field, Reset Interval, sets the seconds to wait before turning Clap on again after a triggering. Clap disables when you unlock the phone, but it re-sets after a triggering. This field sets how long should pass before that re-set. The default value is 10 seconds. It can have values from 5 to infinite.
The button simply resets all the three input fields to default. Note that you have to re-open the Clap settings panel to see the default values again.
Accelerometer
4
Very important note: The accelerometer values are based only for the flat upwards iDevice position, because that is the most common way to lay down your phone, flat with the screen pointing up. I will add the implementation for the flat downwards positions in the next updates.
This section should be used only if false-positives are encountered when moving the phone around. Clap uses the accelerometer to prevent triggering the alarm when the phone is moving. These values represent the minimum g-force that sets the device into a moving state, preventing the triggering. Note that the input values are not actual g-force measurements, the value you put in is then divided by 1000 for the X and Y axes and by 100 for the Z axis.
So, if you want to set the device in the moving state when 0.010 g-force is experienced on the X axis, simply take your number and multiply it by 1000, then put it into the field.
Remember that the Z axis will always experience ~1g of force, that is why it is set to 98 by default. Why is that? Why always 1g even if my phone is still? Do you remember the gravity force? That attracts every object to the center of our planet, and also your iPhone. So, unless you plan to use Clap in space, the Z axis should be left like that :)
You can instead play around with the X and Y other values, and find what suits you best. That depends on how much force you use when you move your phone around. Anyway, the default values should work just fine.
Finally, the button resets everything to default, in case you mess something up.
Thanks for reading the Clap Guide. If you have any kind of problem/question/bug report/etc., contact me at me@jndok.net. Have a nice day!
