V2 is the lowest quality LAME VBR preset allowed on What.CD for music torrents.Īt a certain VBR preset setting, the average bitrate throughout the file is usually close to the target bitrate. The two most common VBR presets on What.CD are V0 (with a target bitrate of 245kbps) and V2 (with a target bitrate of 190kbps). V0 is the highest quality VBR preset and V9 is the lowest quality VBR preset. LAME has certain VBR presets ranging from V0 to V9. Since VBR files target a certain quality instead of a certain bitrate, exact VBR file sizes are more unpredictable. For example, a second of silence would receive much fewer bits than a second of loud, blaring music.
This means that every second of the file has a different number of bits that depends on how complex the sound is at that second.
When encoding a variable bitrate (VBR) file, the user (you) chooses a preset quality and LAME targets that quality, letting the bitrate vary throughout the entire file. Similarly, AC3 and DTS are music formats often found on DVDs and since they are lossy, they cannot be converted to other formats without a loss in quality. We allow AAC files bought from the iTunes store because there are often iTunes-specific bonus tracks, and since AAC is lossy it cannot be converted to other formats without a loss in quality. MP3 is the most popular lossy format on What.CD.
MP3 (the minimum bitrate for MP3 is 192kbps (CBR))ĪAC (can be trumped by any MP3 torrent unless it was bought from the iTunes store and includes iTunes Exclusive tracks) However, you can download the FLAC and convert to ALAC (for iTunes) or whatever lossless or lossy format you prefer. While there are several types of lossless and lossy music formats, only a few are allowed to be uploaded to What.CD.īecause lossless formats can be transcoded between each other without a loss in quality, the only allowed lossless format on What.CD is FLAC.
