I need a software that would decode a magetic card .wav or .bin audio files into numbers and characters and display the result in a human readable format. The required data is embeded in the audio files and need to be extracted. The files also contain lots of noise and [login to view URL] files maybe interrupt swipping,sw must combine data and give me real data . i know some people use some sw for clear noise and repair file before decoding with media editor goldwave , audacity and etc......
Looking for an ALREADY WORKING software basically capable of:
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
If you have experience in Aiken Biphase/F2F decoding algorithms and have a working solution, sample WAV files will be provided.

Hello,
This is an expert developer with high background on signal analysis and I would like to estimate your request.
Could you provide some sample file including the resulting data which contains? This way I will be able to perform some tests against it.
Best Regards,
David
program written in Visual Basic can handle any length od audio file input and will decode track 2 audio into human readable characters, whith added check of LRC and LUHN characters. Interupted or partial swipes in either direction are decoded as far as possible. Missing digits can be guess at or incorret digits can be changed while trying to recreate full card track. Audio is dynamically pre-processed to remove noise and improper/variable signal levels.
