How to stich mp3s together with ffmpeg

Question

I need to to make 10 mins videos with 5 x 2 mins mp3 samples stitched together. How would you do that with ffmpeg from the command line?

Answer 1

I don't think FFMPEG can do this without some crazy command-line fu, but MP3Wrap was designed for this purpose.

You could also use the cat command on Linux:

cat file1.mp3 file2.mp3 > combined.mp3

which will combine file1.mp3 and file2.mp3

or the copy command on Windows:

copy /b *.mp3 c:\combined.mp3

which will combine all mp3 files in your current directory to C:\combined.mp3.

but the cat and copy methods often have undesired effects. The main problem is that the wrong length for the mp3 file could be reported, which may give some audio players problems -- and lost ID3 tags. MP3Wrap solves both of these issues, and is available for Linux and Windows.
