Frequency comparison

Frequency comparison app will display the frequency graph of up to 4KHz in 7.7Hz increments is calculated by entering the sound from the microphone of the android body .
When such as cracks and cavities and unevenness in the object is there change will appear in the graph .
I will comparison display and compare calculated frequency graph file sample .
The frequency graph images holder of SD memory it will jpg save .
Please use such as product inspection and preservation and documentation creation .
Frequency comparison app please use the Android tablet If you use a dedicated Since Internet communication is not used .
Android 4.1 you can use in subsequent models .

Frequency graph continuously created and saved way
1 . Or to the sound source as close to the microphone of the Android body away When the graph appears, hit the object as close to the microphone of the android body to the object .
2 . Save the images holder of SD memory continuously displays the frequency graph in one -second intervals .
3 . Press the Back button .
4 . Unnecessarily Natsuta frequency graph file is moved or deleted from the images holder using a file manager application (ES file ) .

Frequency graph creation and preservation method
1 . Or to the sound source as close to the microphone of the Android body away When the graph appears, hit the object as close to the microphone of the android body to the object .
2 . Press the graph SD save button numerical value of L is make sure that there is at 200-600 , to save the frequency graph to images holder of SD memory .
3 . To record frequency graph creating conditions , date, time, and time shape , materials and diameter , length, thickness and weight , etc. to note .
4 . If you want to start over , press the graph Delete button .
5 . Press the Back button .

Frequency graph reading, comparison, How to Save
1. Press the sample graph read button.
2. Press the name of the read want frequency graph file.
3. Or to the sound source as close to the microphone of the Android body away When the graph appears, hit the object as close to the microphone of the android body to the object.
4. View frequency graph, yellow in the case red size comparison side in the case graph of comparison side is smaller than the sample graph, close to the sample as red and yellow is less.
5. The frequency graph maximum level frequency of F compared to the first stage of the sample and the second stage, it is similar to the same.
6. Numeric value of the comparison is 0.8% less than the same percentage is high, 1.0 percent is the case not equal to the value equal to the value is the same.
7. From the second stage of the frequency graph maximum level number is 200 L Press the graph SD save button to make sure that there is at 600, and stores the frequency graph to images holder of SD memory.
8. We want to record the frequency graph comparing conditions and date and time in the memo.
9. If you want to start over, press the graph Delete button.
10. Press the Back button.

Unnecessarily Natsuta frequency graph file should be moved or deleted from the images holder using a file manager application (ES file).
Frequency graph file can be printed by the printer can see in the Android App.
F is the frequency of the largest sound of frequency graph.
L is the level of the biggest sound of the frequency graph, please adjust the size of the sound value of L to be 200-600.
Frequency graph created with the FFT calculation. SAMPLING RATES 8KHz FFT 1024 Point

View of the frequency graph
Vertical line is the memory of the frequency, is up 4KHz in increments 7.7HZ.
Horizontal line is the size of up to 0-600.
If the form of a graph is a Yamagata simple shapes, materials and density, the graph is not uniform and is complex. FREQ
