wma volume increase?

[kleinma]

Does anyone know of a method or app that can take a wma (or wmv) file and do a volume increase on it?

Looking for something in the realm of freeware (found a few paid apps) if possible.

Just straight gain, or a normalisation?

There are many tools that will apply an increase in volume, but most aren't sophisticated enough to normalise properly.

Finding tools to normalise audio (wave or MP3) is easier than finding ones that will also work on video formats. So: I would use a free tool such as ffmpeg to demux the video, then normalise the audio stream(s) using another tool, and then recombine them using ffmpeg.

ffmpeg built for Windows
normalize

Both command-line, so you can pipe, redirect, and batch process to your heart's content.

I am already able to demux via Windows Media Encoder 9. There is a utility to extract the video or audio portions of a wmv file. This is how I got the wma file in the first place.

However I am already stuck on another issue, which is that windows movie maker (yeah I know its not the best video editing solution, but there is a story behind this), does not output the audio when I publish in 5.1 format. It auto flattens to 2 channel, and I was trying to avoid that.

Since I already did all the editing in WMM, I really do not want to have to migrate this project to something like premiere, which I know has far superior control, but much much more to actually deal with in terms of editing/publishing. If I move the project to anything but WMM, I will have to redo all the edits which I spent about 2 days on.

I suppose I should have done a bit more testing to make sure everything would work out in the end, but you go down so many avenues when trying to figure certain things out, as soon as one starts to seem like its doing what you need it to do, you just run with it.

Basically though, when all is said and done, I am just looking to get this all done with as few encodes of the video as possible, in order to preserve video quality. Everytime you pass it through a video encoder, it generally ends up a bit worse than before.

I've used audacity to cut & splice & decrease music volume... fairly easy to get the hang of it. Documentation leaves something to be desired, but once I got the hang of it, I've been able to string to gether a nu,mber of elements into something that sound pretty good.

Even though it's on PortableApps.com and intended to run from a thumb drive, it can be jsut as easily installed to a hartd drive and run from there.

I use audacity now when dealing with WAV/MP3 type files, however it does not support WMA in any fashion.

I actually am now mulling the decision to try this project over again in adobe premiere (someone in my office has the CS3 suite on a quad core machine). Even though there are about a million more options to configure, I am sure it supports multichannel audio, and WMM simply does not support that at all (confirmed by MS site).

Moved to Gen PC.

I think this also depends on the codecs you have available. When you are exporting from WMM, you may get a choice regarding the size you want the file saved as. If you choose 'best quality', then you may get the volume you want.

And you already know that WMM allows for volume increases in the timeline?

[kleinma]

WMM (in vista) sets the volume of clips to the max by default, and you can adjust downward only. I believe in XP the volume slider defaulted to the middle.

I found out adobe won't do what I want either, as it seems it does not support 6 channel audio files either. It is fully capable of outputting multichannel audio, however it does not read in a multichannel audio file and process it as such, it flattens it to stereo.

I decided to give up for now, and just have it with stereo sound. I will revisit it at some point and try to figure out a way to keep the surround sound.

As far as just doing the WMA volume increase, it looks like the app "goldwave" has that ability.

FlexiMusic Wave Editor is a program that lets you edit volume levels in Wave files and you can change the speed or tempo of the song. It will allow you to increase the volume for WMA and MP3 tracks and MP3 albums very easily.

what is making you stick with wma format? ac3 format was designed for this.

[kleinma]

It was just for one specific project, and this thread is nearing a year old

[techgnome]

Lord - besides, not everything supports ACCC ... I'm running software that doesn't... so I'm left with wma or mp3...

did you try this

[Lord Orwell]

do you know of any audio software capable of recording more than one channel of audio at a time? I have some old quadrasonic 8-tracks.

I'm sorry, that's a new issue... please try to limit problem to thread ratio to 1:1....
