Job Description

Requirement : To provide a software which can output .wav file decode the binary data in it at particular intervals with the time stamp.

Theory : The wave file can be of any length and size. Inside the wave file , it contains waveform of magnetic data at various intervals. This magnetic data is in the binary form .

--Data Bits-- Parity
b1 b2 b3 b4 b5 Character Function

0 0 0 0 1 0 (0H) Data
1 0 0 0 0 1 (1H) "
0 1 0 0 0 2 (2H) "

0 0 0 1 0 8 (8H) "
1 0 0 1 1 9 (9H) "
0 1 0 1 1 : (AH) Control
1 1 0 1 0 ; (BH) Start Sentinel
0 0 1 1 1 < (CH) Control
1 0 1 1 0 = (DH) Field Separator
0 1 1 1 0 > (EH) Control
1 1 1 1 1 ? (FH) End Sentinel

Our wave mainly consists of the track 2 from the magnetic stripe.

Track 2 (BCD,75 bpi)-> ;1111222233334444=99121010000000000000?

P.S . Sometime's the waveform is not clear / has gaps between them due to less speed than required making them long. The software should also be able to succesfully decode the results.

Here is an example of a similar software : http://postimg.org/image/f7gtidi7n/

Features of the software : noise reduction / gap identification between wave and output successful result. / ( I will provide all kinds of wave's so you can make some research ) .
