ok i was happy working at 24 bits on my cubase project for recording and rendering etc,,,
theni got the steinberg internal mixing tutorial and they say its better and more efficient to work on 32 bit float. it even says its lighter on the cpu since most cpu work at 32 bits. so what u guys think??? im guessing this only applies to the internal project setup, not on external input recording, im a bit confused,,,. which bitrate u work and WHY?

I don't know man... this float thing does not sound very good to me... I'm really interested at seeing some feedback on this...
I work on 24bits myself. |

if 32bit is more efficient, why does protools only support 24? |

As for 'why', there are quite a few threads here explaining the theory behind it. Basically, using 32-bit float audio means you retain all the detail and dynamic range no matter how loud the audio is, and no matter how many processes and level changes you apply.

tnx for reply. then its better to have the project setup at 32 bit float in general?
and why mixdown a vst at 24 bit , when u want to add more fx??
tnxxx for ur answers |

The bitdepth you specify in the Project Setup window determines the bitdepth that new files will be recorded at. Unless you're recording through VST FX there is no advantage to be gained in setting this above 24-bit. If you want to export processed audio, you can set the required bit-depth to 32-bit in the export window if you need to.
Likewise, if a VSTi has no processing on it, it has a maximum of 24 bits-worth of dynamic range, so there's nothing to be gained by bouncing it at a higher bit-depth.

sorry, VST works at wither 32 or 64 bits float
roll a joint or STFU :) |

so its no use having my cubase project setup at 32 bit float?
24 bits fine by me. but the steinberg guys say that u should always work at 32 bit float because..
it gives more clarity and more headroom .. i think
and work better and lighter on cpu.
so should i stay at 24 or should i go 32??? |

I work with all 32-bit files. Anytime I bounce a vst down to audio I use 32-bit. I run my project at 32-bit. If recording external, I use 24 bit (because thats all my audio card supports). It uses a lot more space, but when I'm fully done with a song, I just burn all the files and data to a dvd and archive it anyway, so I might as well use the best I can.

The advantage of using 32 bit is that you don't need to worry about recording at close to 0dBFS to make sure that you utilize all the bits and don't need to worry about clipping.
The conversion between 24 bit fixed and 32 bit float is very easy to perform, you just have to add the eight exponent bits.
But it makes sense that it would incur a small CPU hit, even if I don't think it will be very significant.
If you are pushing your disks to the max every now and then I wouldn't worry about using 24 bit....it will be using the same resolution as long as you keep an eye on gain structure.
If you're constantly pushing your CPU to max but don't have problems with disk throughput and is lazy with gain structure 32 bit is better.

32 bits has loads of advantages when to 24 bits, from near infinite headroom to "more than you need" precision 
conversion from 32 bits to 24 bits is done using a mantissa (a table with logarithimc commun denominators), while everything will be "dumbed down" to 24 bits precision and headroom it is very usefull during the mix process to have all the available precision
32 bits performance can also be superior to 24bits since modern cpus have diferent processing pipes for float and code/integer, so while one part of the processor is busy execution code, the other is doing float calculations, even in single core processors.
colin: i understood in your post that you were saying VSTs work at 24 bits, and i was correcting that they work at wither 32 or 64 bits float for sound input, processing, generation, etc
