You can use -c copy with ffmpeg to extract audio without re-encoding: ffmpeg -i input_file -c copy audio.m4a Run ffmpeg -i input_file to see what format the audio stream is. If it is MP3 instead of AAC, change the extension of the output file to mp3. This would re-encode the audio as 256 kb/s AAC: ffmpeg -i input_file -ab 256k audio.m4a

Hit the Option key, and the command Convert To AAC will be enabled. The AAC file will be created in the same directory that the mp4 video is located.
I use Evom from The Little App Factory to achieve this. It works very well and it's free. Once you download it, you will see this window: Drag and drop the video(s) onto the window and another window will pop up. For the most amount of control, I recommend the "Folder" tab. Here, you can create a new name for the file, select where you would like ...

It depends on the program that is playing the sound. If I have a youtube video playing in Safari, I can switch between output devices in Audio MIDI Setup, and it works. VLC on the other hand handles the choice of output device for itself, so I have to change it in VLC. The advantage is that I can choose an output device that is not the default one.
SoundBunny might be able to help with this. The primary purpose of the app is to let you control various apps' sound levels, but it also usually shows you what apps have recently made sounds, which might help. You can download a free demo from their website and leave it running until you hear the noise again, then switch over to SoundBunny and see what it ...
this works best for me: Create a folder, for instance called "video stripper". In Automator, create a Folder Action. Associate the Folder Action with the folder "video stripper". Drag the action "Import audio files [into iTunes]" to the Folder Action. 4b. (Optional) add the action "Import files into iTunes" if you want to have the imported audio files ...

Click "Go" menu in the Finder menubar. Select Computer, then Macintosh HD / Library / Preferences Open "Audio" folder. Right click these two files and ...
Turns out I had some strange Core Audio driver issue. Every time Skype was running, process "coreaudiod" would fire up and begin to hog CPU like crazy. I fixed permissions on my boot volume and it fixed a bunch of stuff related to iTunes, which apparently also fixed whatever was going on. Once the coreaudiod issue was resolved, here's the setup that is ...
