Bit depth??

I read in a Magazine that live internal processing brings the bit depth from 16 or 24 to 32.

Does this occur even if i don't plug anything in the signal chain inside Live?
If i record a track to 24 bit depth, am i supposed to bounce it to 24 or 32 if i want to further process it in another application?

Thanks,

Paolo

no, no, no !

Live just use internal 32 bit internal floating point processing, as does Logic, Cubase, Samplitude, etc,etc. This does not affect the bit depth of the audio files you use.

you do not need to bounce it to 32 bit files. Although if you freeze a file in Live, it is rendered as a 32 bit audio file with no options to change, but that is the exception.

the Live engine is 64 bit floating point, not 32.

i was talking about the fact that Live automatically brings the bit depth of the audio tracks from 16 or 24 to 32, if you use any kind of plug ins in theirs chain.

I read this on the Music tech focus magazine on Ableton Live in the section 'better sound quality'. They explain this and after they suggest to bounce tracks choosing the 32 bit depth in the Export audio Video command. Even if you do resampling you are supposed to set 32 bit depth.

This really sounds strange to me, and this is why i'm posting here.

PARTS of the Live engine are 64 bit. (the mix summing). Not the whole audio engine. Sonar and Reaper if you have a 64 bit o/s are the only ones which are completely 64 bit and they have a 'bitbridge' to allow 32 bit compatibility for older plugins etc.

Many plugins do run natively at 32 or 64 bit depth. EQ8 in HiQ mode being one example of something running at 64 bit mode.
