What affects sound quality in CD burning?
Really, unless the burning plumb fails, the burning process shouldn’t have much impact on the sound quality – the track burned on CD should sound just like the track played from your PC. The effect on the sound quality comes mostly from the ripping process (where problems may introduce unwanted noises or gaps) and from the encoding process (if the file has been transmitted as MP3 – some quality loss is inevitable, but it can be kept to a minimum by using good encoder software at a reasonably high bitrate).
