Increasing audio quality

[rst1953]

Is there a external audio gadget that I can use in tmpge. Low volume when I take a avi and convert it to mpg. Useing tmpge plus!

thank's for the info

Several ways you can do this

1. the simplest is to use TMPGEnc itself. Under the Settings, Audio click on setting and you can change the volume (a normalise option is present). I use this a lot and it works just fine

2. use VirtualDub, open the AVI file and choose Audio menu, select full processing mode and then select the volume option, select an appropriate gain. In the Video menu select Direct Stream copy and then save the AVI to a new file name.

3. similarly using VirtualDub open the the AVI and the save the audio as a WAV file. (File, Save WAV). Then open your preferred audio editing program and change the volume. An example program is Goldwave (www.goldwave.com) but you can use the basic sound recorder that is built into Windows

don't know if there's any plugin directly for TMPGenc, but you could use Virtualdub first to strip a .wav file from the .avi, then use wave editing software to process it and make it louder.

As far as wave editors out there, you could go with Audacity - http:\\audacity.sourceforge.net - which is free, cross-platform, easy to use, and supports VST plugins.

Then once you have the audio the way you like it, you specify the modified audio file instead of the original audio when you encode to mpeg with TMPGenc.

it's not that hard, and it doesn't take a whole lot of extra time - I just did a noise reduction on a super noisy capture, the avi file was 26Gb. It took Virtualdub about 6 minutes to render out a 700Mb wav file, then it took my audio software (Wavelab) about 2 minutes to set up a noise reduction filter, and another 2 minutes to save the edited wav file.

hope this helps.

Thanks for the help will combined both post for hopefully a good result.
One other thing please if you can help.
With the xvid/ac3 audio I been converting it using ac3tool.
First I strip it in vdud and make a wave for tmpge in ac3 tool. When I use ac3 tool is there someway to increase my voloume then?

Another way (which sounds a lot easier to me) is to use an external encoder, e.g. Toolame (see tools). A lot of previous postings suggest that this MP2 audio encoder is a lot better than the encoder within Tmpgen. In the environmental settings, there is an option to use an external audio encoder. Simply enter in the file location of the external audio encoder that you've downloaded onto your computer. Works OK (encodes begin with doing the audio first), although I've never done any comparisons between these audio encodes vs the internal Tmpgen encodes. Hope this helps.
