[solved]How to extract sounds from a video?

[maverick6664]

Hi,
This may be easy, but I don't know how. How can I make a .wav or .mp3 sound file from an .mp4 or .avi video file? sox doesn't support this....

TIA!

Hi,

you could use a GUI such as avidemux2 or ffmepg on the command line: ffmpeg -i <video_file> -acodec copy <mp3_file>

Thank you, but the audio file made by ffmpeg becomes mp2 instead of mp3. How can I make an mp3? And I cannot make a 128kb bit rate file. I use "ffmpeg -i <video> -acodec copy -ab 128k <mp3_file>

Hi,

you could try this one:

Code: Select all

ffmpeg -i <video_file> -acodec libmp3lame -ar 44100 -ab 128k -ac 2 <mp3_file>

This how to is about converting DVDs to h264 but there is one step about extracting audio with mplayer:

Code: Select all

mplayer movie -aid track_id -dumpaudio -dumpfile where_you_want_audio.ac3

or if there is only one audio track in the video

Code: Select all

mplayer movie -dumpaudio -dumpfile where_you_want_audio.ac3
