How to merge video/audio files with FFmpeg

0. Prerequisite

Download FFmpeg from www.ffmpeg.org/download.html

1. Prepare a .txt of all files to be merged

Example:

file '/path/to/file1.wav'
file '/path/to/file2.wav'
file '/path/to/file3.wav'

Automatically generate the input file using Windows command line:

(for %i in (*.wav) do @echo file '%i') > mylist.txt

2. Concatenate using FFmpeg

"C:\path\to\ffmpeg.exe" -f concat -i mylist.txt -c copy output.wav
