thinking of upgrade to elements 7 from le 7

Thanks for the reply.

I’d here like to add one more question. I export the audio mixdown at 24 bitrate in the form of WAV and I find the sound quality is not as good as the CDs’.

I know the recording format in Cubase is 32-bit float and I heard something called “dither” in versions other than LE.
Is that helpful?
