downsampling a project (96 to 44.1)

[asw000]

i started tracking at 96K (with my new Traveler). and now that it's time to mix, my CPU can't handle it. so i started to downsample everything to 44.1K. This is a full album.

when doing the downsampling through DP (4.6.1), it seemed to take FOREVER when set to the high quality rendering. i mean for a 10 track tune, i would set it to change the sample rate over night, and when i woke up in the morning (8 hours) it wasn't even half way done.

so i started to do it through Peak, which was much faster but i don't know what quality i'm losing. to my ears, i can't really tell the difference. before i got too far along the conversion, i thought i'd ask the group what they thought.

my question is, what is the best tool for converting sample rates? is there something wrong with my DP conversion, or does it normally take that long?

are there other more deticated applications that i should be using? other techniques i should use?

I have an AMD PC and never had it take that long and with a computer like you got it should be even faster, I use Wavelab for all my Converting never takes longer than 30 sec for like a 4 minute wav.

Wait... are you saying DP took 8 hours to half-way mix down a 10 track tune? Or do you mean telling it to batch-convert all of your tracks to a different sample rate? Were some of these tracks recorded many, many times (in which case, they could contain dozens of different recordings of the track)? Either way, that still seems like way too long.

If you mean that it took 8 hours to mix down the recording, I think I know what's happening. You're running hours or days past the end of the recording. Stranger things have happened. Not sure why it happens, but I've seen similar on occasion. Fortunately, if that's the problem, it's easily solved.

Try selecting one track for the entire duration of the song plus a bit for any reverb decay or whatever, then hold down... I think option, but I could be remembering wrong---I don't have DP on my laptop, which I'm using to write this---and look at the Edit menu and the "select all" will become "select all in region" or something similar. Choosing that option will select all of the tracks for the selected time period. Then tell it to mix down only the selected material. See if that doesn't help considerably.

my question is, what is the best tool for converting sample rates? is there something wrong with my DP conversion, or does it normally take that long?

Something's really odd. Laptop drives are slow, but not THAT slow. You should be able to do a mixdown in substantially less than the actual playback time. If not, something is very, very wrong.
