Is audio extraction different than raw mode ?

It's me again, with a weirder question

Several times on forums, people have argued that CloneCD was reading CDs, even audio, in raw mode. Sometimes it was answered that CloneCD was just performing a burst mode audio extraction, many answered that it would copy errors if there were some... and I often answered that audio (CDDA) was a raw mode anyway, so that any ripper would be in "raw" mode ripping them.

But I must admit that I never found the exact relation between the read or write commands and what the programs offer. For example, when I ask Nero to write an SAO CD, I don't know if it writes in MMC-RAW, MMC-SAO, or SAO-RAW !

So when CloneCD reads an audio CD, does it use the same command as CDex or EAC (regardless of jitter correction), or is there a RAW read command that works with both Data and audio, besides the read command used to extract audio ? If so, does it behave like a burst extraction or a jitter-corrected one ?

I don't know what those programs are using - but my guess is that they all use the SCSI-3 MMC specs for reading/writing of most drives. Of course some drives may not be MMC compliant and so custom instructions are used - maybe for early TEACs (I'm not sure).

Anyway, if using MMC specs...

There is only 1 read command when it comes to reading sectors but it comes with various options. Yes, the raw mode reading is a single command for both audio and data. And yes, all of those programs you mentioned use the same raw read command.

I think some people got confused and started to think that some options were different:
1. Real term: Disable ECC/EDC in hardware
and return data to PC (uncorrected)
- In CloneCD it's known as FES on and error correction
set to none
- In Blindwrite it's so called audio extraction mode
(for data)
2. Burst mode just means normal raw reading mode - where by
the software instructs the hardware to read more than 1
sector in a go
3. The jitter correction option that exists in software are done
by the software - the MMC specs don't have a command for
turning on or off jitter correction in hardware. Don't get
confused here, most drives do jitter in hardware, but the
option mentioned is what the software would do it self -
nothing to do with the raw read command either

Any comments from others...

Thank you

Could you please look at this thread?

I've same problem on audio extraction. It is:
How to extract faked audio tracks (real data track signed as audio) is raw mode?
