I would like to ask for a feature that corrects the DC offset of a music file during the CD ripping process before saving the file.
That is something that I currently use Wavelab for.
Which creates a lot of boring extra work.
-> Open each file in wavelab.
Choose function to correct DC offset.
Save file again.
As this function has no parameters to set, it could be integrated as a flag option in the encoding settings dialog.
And thanks for the great work so far!

Why? Can you actually hear a difference?

I think the purpose it to have the ability to recreate pressed CD's perfectly with a CD burner.

No, but when i rip CDs, might as well do it perfectly and be done with it?

The possible DC offset is present in the original waveform. "Fixing" it alters the waveform instead of preserving it. A perfect rip copies also possibly the existing DC offset.
DC offset is an entirely different thing than the so called CD read offset (and read offset correction that can be applied in some rippers).

I'm a bit confused too. why would you want to alter/process the WAV file by adjusting DC offset of music from a CD? DC offset (if any) would have been done at the mastering house before pressed to CD. Is it that you are talking about the read offset, not DC offset?

Sorry for my late reply..
Yes, the DC offset is actually already part of the original waveform.
I am not a sound engineer, so my explanation is not a professional one...
What I learned is that the DC offset is an error occuring already during the recording or mastering process.
The result is very small differences in the timing between left and right channel in stereo recordings.
Current CDs seem not to have this error anymore. So the music industry has obviously developed further. But I have lots of "old" CD from the late 90's to early 21st century that have the offset.
Using software like Wavelab it is possible to correct this error after ripping a CD.
What is this good for?
The sound after a the DC correction is much more precise. Espescially bass and drum sounds are more accurate and the overall sound experience is more transparent.
Of course it depends on the level of "uncorrectness" of the original CDs (and the quality of the used hifi equipment).
But I would compare the difference with that between a 128kbps MP3 and a 320kbps file. Just to give an example.
Of course it could be discussed if that kind of data manipulation should be part of MC. But there is also the DSP-Studio included...
Wavelab (even in the Elements Version) is a very powerful tool which is far too big for my purposes. But I still had to buy it due to a lack of alternatives.
