Click For Summary

Discussion Overview

The discussion revolves around finding applications to capture audio from video files, particularly focusing on converting audio to .mp3 format and modifying audio quality. Participants share their experiences and recommendations for both free and paid software options, as well as techniques for improving audio quality.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant seeks an application to capture audio from various video formats into .mp3, preferably free.
  • Another participant questions the specific video formats the original poster is working with, suggesting the need for a versatile application.
  • Some participants mention the importance of capturing audio from lectures and interviews for personal use.
  • Several software options are proposed, including ffmpegGUI, Adobe Premiere, and VirtualDub, with varying degrees of cost and functionality.
  • There is a suggestion that any competent video editor or mp3 encoder should suffice for the task.
  • Participants discuss the need for software to manipulate sound quality in mp3 files, with references to Adobe Audition and LAME for encoding.
  • One participant shares their experience with Audacity for audio editing, noting its features and limitations regarding noise removal.
  • Another participant describes using a SoundBlaster sound card for recording and processing audio, mentioning specific features that could aid in improving audio quality.
  • Concerns are raised about the effectiveness of noise removal tools, with one participant expressing dissatisfaction with the results they achieved using existing software.

Areas of Agreement / Disagreement

Participants express a range of opinions on the effectiveness of different software tools and methods for capturing and enhancing audio quality. There is no clear consensus on the best approach or software, and some participants share conflicting experiences regarding noise removal capabilities.

Contextual Notes

Participants mention various software tools and techniques, but there are limitations in terms of specific formats supported and the effectiveness of noise removal features. Some discussions involve assumptions about the capabilities of software without detailed verification.

Who May Find This Useful

This discussion may be useful for individuals looking to extract audio from video files, particularly for educational purposes, as well as those interested in audio editing and enhancement techniques.

Hello guys,
I'm looking for an application to capture audios from videos, best if into .mp3 format. It'd also be great if I can modify quality by myself.
I'd rather prefer it to be free, but doesn't have to.
Thanks,

What is the format of the video, e.g. VOBs, mpeg1, mpeg2, avi, or are you looking for something generic?
 
Formats are different. It'd be best if an application is for various formats, and captures to various formats also. What I'd like, is to capture audios from various lectures and interviews so that I can put them on my mp3 player and listen to while doing some work or riding a bicycle.

Also, if anyone of you knows a program to capture audios at instant, like from streaming files, radios, etc
 
I think you are looking for something like this:

http://www.videohelp.com/tools?tool=ffmpegGUI"

"Very simple and fast AC3, MPA/MP2 audio encoder tool. Open WAV, MP3, AVI video, MPG video and convert directly to AC3 or MPA/MP2 audio in one step. GUI for ffmpeg. Extract all files to a folder and run ffmpeggui.exe. "

And it is free! :biggrin:

I am pretty sure it won't work for VOBs (the files from a ripped DVD), you can find several trialware programs to rip these files, or you could convert the VOBs to DivX and then get the sound.

By the way, the videohelp website is one of the best sites for audio/video.

Thanks, I'm downloading it right now.

Do you also know any nonfree but very good applications of this kind?

Any video editor worthy of the categorization will do this, as well as most mp3 encoders.
 
Thanks everyone!

Seems to work. What I'd also need is some software to handle sound quality in mp3 files :)

Thanks once again :)

What do you mean, handle sound quality?

I have no idea what you mean.

Easy and nice software for editing audio is:

Formally cool edit pro

To encode into Mp3 (variable quality, etc.. maybe this means handle sound quality)
http://lame.sourceforge.net/"

for audio editing i use Audacity (its free) - you can remove noise, change volume, cut and paste, do effects, and encode to mp3/ogg/wav... you can convert to mono, set sampling rate etc.

but I'm not sure if it supports surround.

Right. Sorry for that. I meant, manipulate sound quality, audio quality, just overall quality of a file played.

//
I did a google search and what I've got to know is that a bit rate and sampling frames are major factors in quality of a sound. This I can do with just any converting program.

Thanks Chroot and everyone out there!

i just installed audacity..but i guess noise removal wasn't that great...!

Is there some way to do it such that it can be done nicely!

If you have a soundblaster sound card, you can just "record what you hear" to a wav file then convert it to what ever format you want. This includes any effects like clean up of the sound, equalization, ... I have a SoundBlaster X-Fi card and it's record utility include recording in multiple formats, such as .WAV, .MP3, .WMA, ... If the video is in a format that the Soundblaster media player can play, you can use the record feature in the media player as well.

For speech, or other vocals, you probably want to compress the volume range (this is commonly done when recording singers for music). SoundBlaster includes a "crystalizer" which appears to be a volume range expander / compressor, but I haven't investigated this yet. If you can compress the vocal volume range, it's usually easier to get rid of background sound, as long as the lowest vocal volume had some room between it and background noise.

i have .wav format only and i fo have many softwares like which show noise removal but doesn't actually do that well...they actually deteriorate the sound quality further...
Actually point is i downloaded some lectures but they have lot of noise and so i actually want to remove all that and just listen voice of lecturer...!
