mp3gain
Many times when I have created a DVD from an AVI file and played it on my TV, I would need to enhance the TV volume nearly all the best way to maximum in order to hear the actors. Proper the action switched, the TV would blare out and almost make me deaf so I would need to lower the volume. Of course for quiet scenes I'd to enhance the volume again. This started to obtain very annoying. I told myself there must be an easy method where I possibly could normalize the AVI and have the quantity level at typical TV volumes to ensure that I would not need certainly to constantly raise and lower the quantity depending about what area of the movie I was watching.
I'd the similar problems for my mp3 normalizer music files but I could equalize these in order that they all played at the same volume when I played the CD in my car or audio system. The amount from an AVI file can't be treated just like a mp3 music, since the AVI features a much wider range of sound. AVI sound can go from very low to very good where mp3 volume is often at a far more steady level.
To see if I possibly could make a move similar, I performed a research by having an AVI file, that after I created a DVD, had this very low volume evoking the TV volume to be cranked up and cranked down constantly.
The next were the program programs I used.
1) Audiograbber 1.83 by Jackie Franck
2) MP3gain by SourceForge
3) Normalize-0.253 by Manual Kasper
4) Pers-o-FrontEnd 4 Normalize Gui for Normalize-0.253
5) Pazera Audio Extractor
6) AVIcodec
All the above mentioned software are free for download. Just Google and find. First thing we must do is to learn what type of audio file is in the mp3gain. We try this by running the AVIcodec program. We select the AVI under consideration and then click on it in the program to see its characteristics.
Within an AVI the audio is typically mp3 and could be either of these:
1) Bit rate of 128 kbs, Sampling frequency of 44,100 hz and Channels 2-stereo, or
2) Bit rate of 128 kbs, Sampling frequency of 48,000 hz and Channels 2-stereo
First thing we do is extract the audio file from the AVI using Pazera. We extract one audio file as a PCM wav file. We then extract the audio file again but as an mp3 file. The mp3 file is usually the audio that's encoded in the AVI vedio file. If the mp3 file is sampled at 48000 hz then you definitely need certainly to extract it first at 44100 hz as that's the way audiograbber expects the wav file to be.
