Most CDJ’s have problems with Variable Bit Rate (VBR). Most Denon MP3 players can’t set a MEMO, can’t Fast Search, can’t Quick Jump, and can’t see Time Remaining with a VBR file. Their is a neat and free software that converts all your VBR to Constant Bit Rate (CBR) without losing audio quality. It’s called WinMP3Packer 1.13

Basically, if you have a VBR that is 128kbps – 256kbps, it will create a 256kbps CBR. Your file size will increase but hard drive space is very cheap nowadays. Reasons why you might want to use this tool: . Reduce the size of high bitrate CBR files, turning them into VBR files. (This is the original idea of mp3packer) . Take a Variable Bitrate (VBR) MP3 file and convert it into a Constant Bitrate (CBR) MP3 file. WinMP3Packer does this by finding a CBR bitrate that the VBR file will fit into. This is useful if you want to play the audio on hardware players that do not support VBR files properly (e.g. Pioneer DJ equipment, CDJ-200) . Strip headers from the start and/or end of the files.
