ffmpeg would do this, and I've had excellent luck with the winff front end to it. It'll give you the commands should you want to do it manually, let you batch stuff out, or strip out the audio. It also has a sane set of common presets for things you want to do

I'm going to answer this by recommending gstreamer. You're probably going to hate this answer, because it technically satisfies your requirements, while not being GUI-based. But that's okay, because someone else may find that this is the best tool for the job for them. Basically, if you get a build of gstreamer with all the codecs enabled, it supports an ...

I use youtude-dl for downloading videos from YouTube. It's a console program (without any ads), written in Python.

You can set the format too, for example: youtube-dl --extract-audio --audio-format mp3 "...

What you're looking for is probably a Fast Fourier Transform, or "Frequency Analysis". Audacity can do this, with the Analyze -> Plot Spectrum… tool. This will output a graph, and you simply find where it peaks to ascertain the Hertz value of whatever sound you were analyzing. This of course only works if the tone is constant. If your sound file ...

Except for two caveats (price and ISO see below) DVDFab will work great for that. The only functionality caveat: There is a chance it won't natively open ISO files (i.e. I can't remember) - in which case you would have to extract it to a dvd-video folder or mount it using for example PowerISO (Free unlimited time, limited functionality but enough for this ...
