I need an already done software or someone who can make it: 1) Decoding magnetic stripe binary data (5-bit, 7-bit-8bit) recorded in waveform (PCM uncompressed) 2) Supporting interrupted swipe recordings, in other words, WAV recordings with gaps/silence Software must be able to decode a waw wave wma or mp3 file. The sound in the wav file is magnetic stripe. If you can do this, please let me know urgent. So basicly I need a tool that will decode magnetic stripe audio sound into a text (numbers ) . The tool must be able to clear the noise in the sound and support interrupted data signal inside of sound file !! . THE sound contains large file of intrerrupted swipe data from track2 ... which will look like this: 1: 1234567890123456789=1234567890123456789? 2: 1234567890123456789=1234567890123456789? 3: 1234567890123456789=1234567890123456789? 4: 1234567890123456789=1234567890123456789? 5: 1234567890123456789=1234567890123456789? ....." "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. Existing open source example: [login to view URL]" Please post ONLY if you really know how to do this and can do in a short-time. sample file and sample program is attached

Hello, I have done exactly this once before, and my algorithm was able to handle quite noisy swipes with ease.
