Guys how do I save my MP3 collection so the quality doesn't get the quality ruined? I just learned about this

>Rotational velocidensity affects all audio files encoded with lossy compression. These include mp3, aac, and ogg.

>The most notable effect of rotational velocidensity is the loss of bitrate in files. A lossy audio file will lose an average of 12kbps a year. But, this can vary greatly depending on the type of storage media used.

>Examples:

>SATA HDD: ~12kbps
>IDE HDD: ~15kbps
>SCSI HDD: ~7kbps
>DVD: ~16kbps
>CD-R/RW: >21kbps

>This can be overcome by compressing audio using lossless formats such as FLAC, APE, or TTA. These formats are designed to never lose quality over time, and will sound the same right now as they will in 10 years.
