ext m4a.īy default, all streams from the input file will be written to the output file. Using the -ext option, you can supply a different output extension common to all output files, e.g. If you don't specify the output file name for an input file, the container format will be MKV, and the output will be written to normalized/.mkv. In this case, the container format (e.g.wav) will be inferred from the file name extension that you've given.Įxample: ffmpeg-normalize 1.wav 2.wav -o 1n.wav 2n.wav You can specify one output file name for each input file with the -o option. Just give the program one or more input files as arguments. All audio streams will be normalized so that they have the same (perceived) volume. The program takes one or more input files and, by default, writes them to a folder called normalized, using an. Please read this section for a high level introduction.
