Pazera Free Audio Extractor takes the audio from most major video files without loss of sound quality or converts them to a variety of common audio formats. The program can also behave as a simple conversion tool from one audio format to another (e.g. AAC to MP3).
Some supported formats include (audio) MP3, AAC, AC3, WMA, M4A, FLAC, OGG, WAV, ALAC, WavPack, AIFF; (video) AVI, FLV, MP4, MPG, MOV, RM, 3GP, WMV, VOB, MKV, WebM and OGV.
Note: By default, the program will extract/convert to MP3. Select "Try extract original audio stream" to avoid re-encoding, which is faster but may result in a format that some devices can't read. The program has a number of predefined settings (profiles) specially designed for novice users, but you can also customize audio encoding and output parameters.

Latest version of Pazera supports audio extraction of WebM videos. So you can decode and grab the original OGG Vorbis stream with Pazera. Woohoo!
FYI, if you're extracting the WebM version of a YouTube video, the audio source is lesser quality than grabbing the highest-quality MP4 file by about 20kbps (at least from my initial testing).
v2.0
The official download link to the portable version of the program was changed to: http://www.pazera-software.com/files/Pazera_Free_Audio_Extractor_PORTABLE.zip
Sorry for the inconvenience. Thanks, Jacek
v1.4
YouTube converts the audio so if you are converting YouTube's video to MP3, what you're really doing is decoding and re-encoding the audio twice. (Three times if the original source wasn't lossless).
It helps if you download the most high bitrate of the video (720p or higher). 360p-480p vids use roughly 96kbps VBR; 720p-1080p uses 192kbps VBR.
v1.4
If I extract an mp4 with aac audio that I downloaded from youtube and in the program I choose mp3 rather than "extract original audio stream"(which would be aac), am I losing any quality?
I assume the original audio was also mp3 and youtube converted it to aac. Does the youtube conversion hurt the quality as well?
v1.4
@bitcoin - fixed forum link, good catch
v2.10
