If the DVD does not contain an English-language audio track, the R5 video is synced to a previously released English audio track. Then a LiNE tag is added.[13] This means that the sound often is not as good as DVD-Rips. To account for the lesser audio quality typically present in R5 releases, some release groups take the high quality Russian or Ukrainian 5.1 channel audio track included with the R5 DVD and modify it with audio editing software.
