I would like a solver in C# which solves audio fun captcha (audio service). It recognises around 6 digits in an audio file with noise in the background. It should have a function called GetCaptcha. You input the link of an audio and it downloads it with a random name in a temp directory. It then removes the noise and recognises the text and returns the text back in to the string example string link = "[login to view URL]"; GetCaptcha(link) // download audio to temp dir // recognise (result=12345) // return 12345
