This has nothing to do with the original poster's issues, so I changed 
the subject.

There's a reason why people work with floats. And it's not because you 
want to preserve the LSB in case you have a signal that uses a full 24 
bit dynamic range.

[If you take a good studio ADC, they have an SNR of 118dB, that would be 
less than 20 bits. A very good studio grade DAC would have a 120dB SNR, 
that's 20 bits, too.]

So, please tell me - how should a 'pro audio chain' look like?
