• MP3 Normalizer

Normalize: Analyzes the forms of your digital music out the peaks and valleys within certain filelist, then cranks up the spots with less amplitude to ultimately create a smooth listening experience. In other word, if the files to be converted have different volume levels, normalizer will convert the files to the same volume level.

1. On main windows, click File > MP3 Normalize.
2. Change the value of 'Normalize to' to control the volume of your created files. If the value is smaller than 50, the volume is lower than original file, if larger than 50, the volume is higher than original.
3. Check / uncheck 'Enable Fade In/Out' to add/unadd fade in/out of your created files.
4. Set the frequency, or number of times an event repeats, or number of vibrations procuced by a signal or sound, in a given period. Frequency is measured is Hz. One Hertz is one cycle per second. In Ease Jukebox, the settings are listed in kHz, or kilohertz. The value you can choose from is 48,000 Hz, 44,100 Hz, 32,000 Hz.
5. Set a channel, such as mono or stereo. A stereo signal consists of two separate audio channels, while mono signal has one. A signal audio file may contain information for one, two, or in some cases, more audio channels. This means that stereo produces better quality sound.
6. Specifies the bitrate. The more bits used to store each sample in digital form, the more thorough the original signal's amplitude can be represented. This in turn may result in higher audio quality in the system. However, the more bits used per sample, the larger the digital audio data size. The value you can choose from is 40kb, 48kb, 56kb, 64kb, 80kb, 96kb, 112kb, 128kb, 160kb, 192kb, 224kb, 256kb, 320kb.
7. VBR Bitrate: Set VBR bitrate. The values you can choose from are 40kb, 48kb, 56kb, 64kb, 80kb, 96kb, 112kb, 128kb, 160kb, 192kb, 224kb, 256kb, 320kb.
8. VBR Quality: Set VBR Quality. Varies from 0 (best quality and worse speed) to 9 (worse quality and best speed).
9. Click 'Select Directory' button to choose the folder where you want to save you created MP3 files.
10. Click 'Add' button or click File > Add to add the MP3 files you want to normalize.
11. Click 'Delete' button or click File > Delete File Record to delete the files you have selected from the filelist. You can select more than one file by pressing the Ctrl key while clicking the files or pressing the Shift key and using the arrows to select a range of files. Your files will not be really delete from your computer.

13. Click 'Start' button or click Action > Start to begin your conversion.
14. Click 'Stop' button or click Action > Stop to stop your conversion.
15. If you are not satisfied with your setting and want to use default setting, just click 'Default' button. By default, fade in time is 10s, fade out time is 20s, Frequency is 44,100, Channel is Stereo, Bitrate is 128kb, VBR Bitrate is 128kb, VBR Quality is 5.

Attention:
1. You can only add MP3 files.
2. step 2-9 must be done before step 13.
3. Protected WMA files cannot be converted since they are locked.
