7. FAQ

What is MP3 ?

MP3 is the technical abbreviation for a method of compressing audio files into digital formats. (MPEG-1 Audio Layer 3) This is the most used compression scheme. It can compress the standard audio track to smaller size and doesn’ t degrade the sound quality

What is VBR(Variable Bit Rate)?

The bitrate of a compressed file is the main determinant of sound quality. The bitrate is the amount of data stored for each second of music. CBR compressed files store the same amount of data for every second in the file, even if some seconds contain very complex music and others contain very simple music. VBR files by contrast, vary the amount of data stored depending on the complexity of a particular section of music. In a symphonic piece, when the full orchestra is pounding away the bitrate will be higher, and when just a single flute is playing, the bitrate will be lower.

Ideally you should get smaller, higher quality files with VBR, but this isn't always the case.

What is BRM?

BRM is the technical abbreviation for Bit Rate Modification, named by Etronics Corp. This is appropriate method for the portable player as well as keeping the highest compressing ratio by using VBR.

The 25:1 compressing ratio is based on MPEG II, and 15:1 is on

MPEG I. ’ BRM’ is assigned to extension(.brm) of music file(s) downloaded on the audio card.

Can you play the BRM file on your PC ?

No. The BRM file is encoded by RC5 128bit security, thus, you can not play it on your PC and another MP3 player except the audio card.

14-14

Guides for USB downloader management program

What is the reason of non-constant compressing ratio in the voice download mode?

VBR files vary the amount of data stored depending on the complexity of a particular section of music, therefore the compressing ratio is relatively smaller when compressing complex music like classic, pop, etc.

Why is there quality difference between directly compressing CD music and compressing by MP3 ?

MP3 is lossy compression method; it compresses with discarding the inaudible sound. This method cannot preserve the exact CD sound source, so the quality of sound compressed with MP3 is worse than directly compressing CD music.

Can I save the file that is not music one?

It can be saved on the audio card, but not uploaded for protect copyright. And already saved file(s) cannot be changed.
