In the tests I've performed, 48 bit fixed signal path sounds better than 32 bit floating. But to be completely fair about my tests, it could easily be an issue of offline bouncing versus realtime. It is difficult to find a mastering application which is Native and doesn't bounce offline. My basic rule of thumb here is if sonic quality is of utmost importance, bounce in realtime regardless of the format. I don't want to get into a needlessly heady conversation as there's so many other factors involved that for 99% of everyday users, there isn't going to be a big enough difference between the sound of 32bit floating versus 48bit fixed to make it deciding factor on putting together a system. Not until we start talking about Rooms, and monitors and high end converters etc. etc. can we really even bother with thinking about it. IMHO When I say Zero latency for TDM. I mean that for recording purposes, there is not enough latency to effect the performance. There isn't such a thing as completely zero latency for digital systems. You need so many samples to get though the conversion. But TDM systems can handle dozens of tracks recording simultaneously with only a few samples of delay. There are even great plug-ins with such a low impact on latency they can be used during recording. Even a Modest computer can handle it. Think macintosh G3 or older. It's why TDM was such a Pro Tool. (ha ha) I haven't had a chance to see the new Apogee symphony cards on a Mac Pro yet, which might be the first native contender to TDM to come along. Once you start talking about software synths the issues change. Any Virtual synth needs X amount of time to perform it's task. It adversely effects CPU performance when the buffer (re: latency) is too low. The only time it doesn't effect latency is if the synth is utilizing DSP other than the Host CPU such as a TDM synth like Virus Indigo. Maybe PowerCore or UAD have some too. Yes, there are notable problems with using TDM in Logic. For one, there is no RTAS support in Logic. Second, using the ESB has serious flaws. BUT, there are reasons to over look these if you need to utilize the strengths of Logic and TDM. AFAIC every application has it's share of Notable problems. There's no perfect system. Define your needs best you can, get what you can afford, and learn to work around the problems. This will always be true. hope this helps bd On Nov 19, 2006, at 7:24 PM, my name wrote: > Message posted by my name <streetlight4@verizon.net>: > > Bob DeMaa <bobdemaa@mac.com> wrote: >> In Brief.
