• How to match two audio files ?

  24 novembre 2014, par Janak Prajapati

  I am trying to develop script which compares two audio file.

  Lets say this is two audio music file recorded by Artist

  file1 : it is original song sung by an artist (Uploaded by admin)
  file2 : it is a file recorded by user. i.e user sings it and upload it to server

  now i want to check how closes is file2 to file1.

  Means i need to check if both songs match or not in terms of Lyrics, singing and all.

  I have searched many thing like audio fingerprinting , ffmpeg library and all it did not worked for me.

  I will go for any web technology you suggest.

  Please help me to find solution.

  Thanks.

• How is better to use ffmpeg with the ASP.NET Core, on Linux ?

  26 mars, par user8245660

  I've got the project (ASP.NET Core, on Linux) where are the several tasks, which relate to the video converting and extracting frames from the video file.

  



  I thought about the two possible options :

  



  

  1. using ffmpeg console utility

  


  2. using P/Invoke with the libavcodec library and others, which ffmpeg uses

  


  



  The second option is miles harder and may be very impractical, because it reminds me developing the new wrapper/library, instead of using the ready products.

  



  I've done googling, but there aren't well-done projects for the C#/ASP.NET Core on Linux platform. There are some good for C++ and Python, but NOT for the C# on Linux/.NET Core.

  



  I decided to look at the first option, which I suppose would be more easier and practical. But, there are some weak places, which can produce many problems. We understand (I suppose), that using the 1st option, the end-developer shall use the process forking. So, there could be possible problems with the process idle and other possible issues...

  



  I'm asking about your practice, because it's my first experience on Linux platform with the video converting/sampling using C#. I've used the Expression Encoder .NET library on Windows platform, but it's other story and it makes no sense, right now.

  



  May be, there are other options, which I can't see right at the moment. I dislike the 1st option because of possible unhandled exceptions, because ffmpeg with such role becomes the black box for the ASP.NET Core backend.
