I have made a little program that uses MP3 files.
My program gives an error reading the MP3 with "MPEG Audio Header not found".

I would like to know if it is possible in C# to add an audio header by code.

What I have tried:

I tried to make a Wav from the MP3 and ten convert this Wav back to MP3 and this helps, but it tikes a lot of work and is time consuming.

We cannot guess why your program produces that message.

Thanks for the answer. Indeed some MP3 files miss the Audio Header which contains information about the Artist, Song, Genre, Album,....
I want to know if I can add this header with C# code.

You can add it using any programming language as long as you understand the structure of the file.

Thank you Sir, I was hoping to find an example on how to do this.

Just use Google and you will most likely find some.

Audio header does not contain artist, song, etc.. details. These can be added either as ID3 v1 or v2 tags, but these tags are absolutely optional, and their absence should never prevent audio stream loading.
Regarding faulting files, are they valid mp3 files in any other software?

The mp3('s) can be played in VLC Media Player, but not in Windows Media Player. When I try to convert it with code to .wav , I get a error message saying there are different frame rates in the file(s). I managed to convert it to .wav somewhere online though, and then back to .mp3 which solved the problem. Very strange.

And do you know how these mp3 files are produced?

Filip D. Williams 2-Dec-21 3:28am

Yes, just once in a while I convert a file from youtube to Mp3 using the site https://ytmp3.cc/uu9cc/. This was never a problem in the past. To check if it was only that file, I tested other youtube files, and the same occured on every time.

To check if it was a problem on that site only, I discovered another site which does the same, and also there it produced the same issue.

You may want to try Audacity (an open-source software). This is what I'm using to normalize my mp3 files, and find it quite handy.

thank you, downloaded it and tried, but this one can't open the file either...
