How can I extract AAC audio from an FLV file recorded/downloaded/ripped/saved from BBC radio station with Replay Media Catcher (http://all-streaming-media.com/record-video-stream/Replay-Media-Catcher-HTTP-RTMP-FLV-MP3-ripper-recorder.htm), Jaksta (http://all-streaming-media.com/record-video-stream/Jaksta-Streaming-Media%20Recorder-and-Converter.htm). I don't want to use a converter that is slow and inclines to some quality loss, so please only software that alows to extract sound from .FLV files.

p.s. I tried MP3 extractor from RMC and it obviously it doesn't work since BBC radio uses AAC audio in FLV broadcasts.

Freeware FLV Extract allows to extract audio tracks (including AAC and MP3 audio tracks) from FLV files

FLV Extract allows to extract both audio and video tracks from FLV files. We will extract AAC or MP3 audio from FLV audio only files:

Download FLV Extract and unpack it.
Run FLV Extract
Tick the Audio checkbox and untick the Video and Timecodes checkboxes:

Open the folder with downloaded/captured FLV file(s) from BBC.
Left click on the FLV file and drag-n-drop it onto FLV Extract.
This will automatically launch the AAC extraction (demuxing) process.


FLV Extract works fine for extracting AAC tracks from FLV streams downloaded from BBC.

Replay Media Catcher (http://all-streaming-media.com/record-video-stream/Replay-Media-Catcher-HTTP-RTMP-FLV-MP3-ripper-recorder.htm) 4 has a couple of AAC extraction presets:
- Audio Extraction (Extract AAC to M4A)
- Audio Extraction (Extract AAC to M4B)

So you can extract AAC tracks to M4A or M4B losslessly using RMC 4 (Jaksta)
