open a wav file in any format and seek audio signal stream for aiken biphase (F/2F) signal then decode the signal according to ISO track 2 magstripe standard starting with direct binary translation, then try to parse 5bit characters from binary.
Produce the deliverables as a Visual Studio Exppress solution as either a VB.net or C#.net winforms project with liberally commented code such that future modification will be simple for novice programmer.
Have a look at an existing open source project to as a starting point. Note this existing project lacks basic signal processing and editing such as remove dc offset, remove section on silence, high-pass filter or filtering to enhance F2F signal, auto amplification level control (dynamic AGC), and any other signal processing techniques commonly used for signal enhancement. Note also he the existing projects does not provide intermdiate raw binary output, in case parity and/or LRC or LUHM errors need to be corrected manually, due to missing/incorrect bit or characters.
THIS IS NOT a project suitable for anyone that does NOT have extensive previous experince with wav file manipulations concerning signal processing methodologies operating on sequencial PCM data points. You should electronics engineering expertise yourself, or be working with somesone in highly knowledgeable in digital signal processing. Be prepared to demonstrate these capabilities vis previous project examples and references, or don't bother to quote.
If you already have this software and can demo it's use, that would be ideal.
