Converting MP4 to WAV

TODO: collapasable, copyable, download, etc

Being as brief as possible, what is the ffmpeg command to make an mp4 video into a .wave fileTo convert an MP4 video to a WAV audio file using FFmpeg, you can use the following command:

ffmpeg -i input.mp4 output.wav

Replace "input.mp4" with the filename or path of your input MP4 video, and "output.wav" with the desired filename or path for the output WAV audio file.The file is very large. What would be some good arguments to optimize for a small .wav file that is still worth using?To optimize the conversion process and generate a smaller WAV file while maintaining acceptable audio quality, you can consider using the following FFmpeg arguments:

ffmpeg -i input.mp4 -vn -ar 44100 -ac 2 -compression_level 12 output.wav

Let's break down the arguments:

• -vn: This option tells FFmpeg to ignore any video streams and only process the audio.
• -ar 44100: Sets the audio sample rate to 44.1 kHz, which is the standard for CD-quality audio. You can adjust this value if needed.
• -ac 2: Specifies two audio channels for stereo sound. If you want mono sound, use -ac 1.
• -compression_level 12: This argument sets the compression level for the audio codec. Higher values can result in better compression but may increase encoding time. Values range from 0 (fastest, lowest compression) to 12 (slowest, highest compression). You can experiment with different levels based on your requirements.

By using these arguments, you can create a smaller WAV file while still maintaining reasonable audio quality for practical usage.
