32 bit depth, sample rate?

[papitopinillo]

I was watching a tutorial internal mixi and the guy mention the best quality for the audio its 32 bit depth i was trying to get there on my protools 9 le and only i can go up to 24 bit there's anyway to set protools for that?
Thank a lot

It's not just about "getting there"... your interface needs to be able to convert at 32 bits as well. I don't personally know of any, and I imagine a truely 32 bit converter would not be an inexpensive one.

Which tutorial exactly? I think you misunderstood what was said. A 32 bit A/D might need a time machine to be able to purchase and have have a whole pile of bits wasted measuring thermal noise...

The mix bus in Pro Tools mixes deeper than 24 bits. E.g 48 bit fixed in HD, 32 bit float in LE, 64bit float in HD native??? (see other threads here on that). It was the mix bus depth that your tutorial referred to not the interface A/D bits.

I wonder why the mix engine is 32bit, but the file system and converter is only 24 bit ?

Seems like 8 bits are wasted ?

Personally I think all the different formats 16, 24, 32 bit is confusing.
There sould be one standard. Also I don't understand why mp3's don't support 24 or 32 bit format.
And in audio converters why was 24 bit selected as standard over 16 or 32 bit ?

Might wanna do some reading up on bit depth, then.

Regardless of what you're mixing in, the bit depth is only a deep as the DA converters allow. Unless your converters are capable of higher than 24 bit, you will only ever "hear" 24 bit.

"Only" 24bit? What kind of audio do you produce that would need 144dB of dynamic range? What super-quiet sound would you fill with an additional 48dB of dynamic range at 32bit?
Currently even the best 24bit converters do not reach true 24bit theoretical dynamic range. I think 18-20bit (120dB) or less will be about the very best you will get in he real world.
Just asking because most modern pop-music has about 5-2dB (or even close to zero) of dynamic range. Even the most dynamic classical music pieces don´t have such a huge dynamic range. Even if you had such a dynamic range at your disposal you would need a super-duper-extremely-quiet-super-isolation-listening room to even be able to hear sounds lower than the quietest room tone in the very best studios. On the other hand you will need serious ear-plugs for the loud parts of the music when it hits full scale.

In addition to Frank's points above,

32bit floating point is 24bit.

The term "floating point" comes from the fact that from the MSB (Most Significant Bit) to the 23rd bit are fixed.

The 24th bit, or LSB (Least Significant Bit - though when it's causing this much of a stir, you might call it the most significant) is continually variable, and can represent the final piece of code to resolve a 24bit, all the way up to a 32bit dynamic range, depending on what it detects.

So it just interpolates between the know values of the 23rd bit and whatever the floating bit last represented - a bit like key frame animation.

It's of no real use at the A/D stage, but it makes for a much more robust mixing environment.

Hope that helps.

Thanks.

thank a lot to everybody the name of the tutorial its internal mixing this guy work with cubase and nuendo and yes the guy said 32 bit floating its kind of confusing ,but carl kolchak said 32 bit floating point is 24 bit ...
thank a lot for the information to everyone
regards.
