Discussion Overview

The discussion revolves around finding free tools to extract audio from video files without limitations on duration. Participants explore various methods and tools, including software and hardware approaches, while considering potential quality issues and technical challenges.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks a free tool for extracting audio from video, noting limitations of existing options.
  • Another participant suggests using mplayer, asking for clarification on the type of video file.
  • A participant mentions using Windows Media Player (WMP) for AVI files but does not provide a specific method for extraction.
  • One user describes using Windows Sound Recorder to capture audio while a video plays, acknowledging potential quality loss due to analog conversions.
  • Another participant recommends VirtualDub for extracting digital audio from AVI or similar formats, suggesting it may be more effective than real-time recording methods.
  • Several participants share their experiences using Audacity with a direct connection from headphone output to microphone input, noting that while effective, this method can introduce electrical noise and requires real-time recording.
  • Concerns are raised about the reliability of recording methods, particularly regarding interruptions from other computer processes affecting audio quality.

Areas of Agreement / Disagreement

Participants express various methods for audio extraction, but there is no consensus on the best approach. Some methods are contested based on quality concerns and technical feasibility.

Contextual Notes

Participants mention potential quality issues with recording methods, such as electrical noise and interruptions during the recording process. The discussion does not resolve these concerns or provide definitive solutions.

Does anyone know where I can get a good free tool that takes the audio from video. I found some but they only do 1/2 of what you want or up to 30 seconds.

What kind of video?
mplayer should be able to do it.
 
Probaly AVI, definatly one that can be played in WMP. I have WMP 10, how would I do it in there?
 
I used to do it using plain old Windows sound recorder. Have that recording in the background at the same time as the video is playing. It seemed to work OK for me. I used this to pull some songs off of movies on DVD.

Although that works, there might be some loss of quality since your method probably has to undergo some digital->analog->digital conversions... as well as be done in real-time [the full-duration of the media].

If the movie is AVI (or WMV or MPG.. possibly with the aid of free plugins), you might be able to extract the digital audio content with http://www.virtualdub.org/ . Open the video file in VirtualDub... File->Extract Wav... Admittedly, this might be overkill for this task... but I use VirtualDub for a lot of my videoediting tasks.
 
I've always just used Audacity. I take a cord and connect the headphone output and then put the other end in the microphone input. It has worked fine for me every time so far.

While this also works, there's now the possibility of introducing electrical noise (e.g., hum) into the audio recording. This must also be done in the full-duration of the media.

One other possible problem with these "recording" (as opposed to extracting) techniques is that it's possible to [momentarily?] mess up your recordings if your computer somehow gets distracted [heavy disk access or cpu usage by other programs] while recording.

Yea it does make it sound quite bad.
