You should be able to burn audio .wav files using pretty much any burning program without compression taking place. The burning speed will not make a difference to file size or compression.
Please let us know if you are making a copy of an audio CD, or wanting to burn audio files that are already on your hard drive? Also what applications are you using?
If you are copying a CD, then just make a direct copy of an audio cd using the preset option that exist in most applications.
If you are burning files from your hard drive - double check what format your original files are in. I know you said that they are wav, but please make sure that you have not unknowingly ripped the files into a compressed format. Windows Media Player, for example, will tend towards automotic settings for MP3 compression unless you specify that you want something different.
I think it would help if you described in detail, exactly what you are doing :iagree:
