When using VSO DvixToDVD to convert AVI to DVD, audio sources are converted into AC3, but resulting in a lower volumen than the original... how can i fix this?
Well you can Try Boosting the Volume in your AVI file before you encode it in DivXToDVD.... You can Do this with "Virtual-Dub" by Loading in your AVI file and then go to "Video" and set it to "Direct Stream Copy" and then go to "Audio" and set it to "Full Processing Mode" and then under "Audio" go to "Volume" and check the Box next to "Adjust Volume of audio channels" and then Moove the Slider up till you think the Volume should be Loud enough and when you are done go to "File" to "Save as AVI" and give you file a Name and save it and in a few Minutes you will have a New AVI File but with Louder Audio..... Cheers
That's fine, but when you select "Full Processing" then you must specify a compression codec. Recompressing the whole audio stream just to increase the volume inevitably will degrade the quality. Worse, if the AVI already has AC3 audio then you must have an AC3 compressor, else you will lose the multichannel information. Where do you get one of these? I've got a mindboggling array of codecs/filters but nowhere do I see an AC3 encoder.
If you decompress the audio in your AVI file and then use Virtual-Dub to Boost the Volume but render the audio as Uncompressed then there will not be any Quality Loss in the audio after Boosting the audio , This is because Uncompressed audio is Totally Lossless so it can Be Processed many Times without quality loss as Long as there is No Compression..... Cheers
Have you actually tried this? Yes, it might work, and the resulting audio file will be *HUGE*. Probably 4-10 times bigger than the video. Anyway, how do you save uncompressed 6-channel audio? Even if the space didn't matter. I'm pretty fed up with many ppls' obsession with "lossless" codecs. They are all wanking themselves. Unless you can trace your precious snippet in an unbroken noncompressed line all the way back to the *original* source, there is just no point at all. This is essentially impossible, unless you recorded it yourself. In that case, your crappy recording equipment would have trashed the content far more than any compression algorithm.
You can Create 6 Channel Wav Files from Dolby 5.1 audio files useing a Freeware Program called "Headac3he" it can also Boost the Volume and Normalize and allow you to assign Channels and apply Low pass filters to each Channel seperately and Resample and Convert Formats and even does 2 Pass decodeing... The Size of a 2 Hour 6 channel wav file is about 3gb which isn"t a problem with the Price and size of drives these days..... Cheers
