Extract audio from video

If I bookmark a video, it may be months before I watch it, if ever, but audio I get around to more quickly. I have more time for listening to audio than watching video, so I’ve started going through my video backlog by downloading the files and extracting the audio to put on my iPod.

I download the video with Video DownloadHelper, a Firefox plug-in, then extract the audio to an MP3 file using Sound Converter. (I assume DownloadHelper works cross-platform, but Sound Converter only runs on Linux.)

DownloadHelper has an option to download and convert in one step, but I haven’t gotten that to work. Also, you can use ffmpeg or avconv to convert video to audio, but they have failed more often than not in my experience. So far Sound Converter has always worked for me.

Update: TubGet will let you enter a video URL and download an MP3 file. I seems to work OK, and is faster than downloading video. There’s also ListenToYouTube but apparently it only works with YouTube while TubGet also works with Vimeo and others.

  1. With the VLC Media Player you can now introduce a Youtube URL and then reproduce / save / convert format as desired.

  2. I guess there are many tools that are available in the market for extracting audio from video such as pazera, AoA, Any, oxelon, audacity, I extract etc etc But I guess the best is Pazera. It is really an awesome software. It is also a FREE software. You can extract file from any format also u can convert your audio to any any other format!

  3. You probably don’t even need to convert to MP3. Most video that I come across these days is already in AAC format, which is a much better format than MP3 and plays back on your iPod as is. I just do the following in ffmpeg to rip out the AAC into a M4A file that can go onto an iPod/iPhone/iPad/whatever:

    $ ffmpeg -i video.mp4 -vn -acodec copy audio.m4a

  4. You may try use Avdshare Audio Converter to extract MP3, WAV, AAC, FLAC, WMA, etc from MP4, AVI, FLV, WMV, MKV, ASF, etc for playing audio on iPhone, iPod, MP3 player, etc on Mac/PC.
