Apparently DVDFab does not have this ability or if it does, I am missing something. I don't want to spend the time and hard drive space to rip the entire audio & video BluRay just for the audio track.
I've found a very easy-to-use program for extracting and creating FLAC files from Blu-ray discs called AudioMuxer. It uses eac3to as the underlying program which installs with AudioMuxer.
First, you need a decrypted BDMV folder. I use Blu-ray Copy from DVDFab to extract the Main Movie, but you can use any similar program. Load the Blu-ray playlist file (.mpls) located in the BDMV\\PLAYLIST folder into AudioMuxer. Select Split into Chapters if you want individual files, Export to FLAC, and then Extract. It's that simple. It can also tag and rename files as it extracts if you wish.
According to the documentation, it will only list and extract the HD audio streams on the disc (DTS-HD MA, Dolby TrueHD or PCM). I've used this on both an audio BD (Grace for Drowning) and a concert BD with video (Stop Making Sense) and it worked without a problem.
AudioMuxer uses the .NET Framework (Version 4) so if you don't have that installed on your pc, it will prompt you to install it. It's Windows-only obviously since you need .NET Framework.
edit: Also, you do need to extract the BD first so it takes some time. I just noticed that was one of your criteria. Of course, you can delete the BDMV folder after the audio extraction to save space.
