Hi,

I have a 80MB AIFF file which was a master I got back from a mastering house. However the tail of the track was cut off but luckily I have a previous version they sent me that was ok.

I dropped the two files in Live and attached the missing tail (30 seconds worth) to the new master (7:30). Cmd J to consolidate, however the new file in my browser now has a file size of 120MB and sounds almost phased!

How can this be? I only added 30 seconds of audio to the end.

I've consolidated before and the two parts always add up to the original file size I'm sure!

Thanks

Were the new files warped again before you consolidated? Consolidate will also use the bit depth you specify in Live's preferences, so you could have made a 24bit file instead of the original 16bit the mastering house likely sent you.

A bit off-topic but does Freeze/Flatten use the bit depth you specify in Live? I ended up with a bunch of 32-bit frozen WAV's and I'm positive that I've been using 24-bit all along..

freeze is always 32 bit IIRC

I didn't warp but the clips were in HiQ mode if that makes a difference?

Turns out the master was 16bit and the my default in Live was set to 24 so I have now set that to 16 and will try again.

Thanks for your help!

If I'm NOT warping and I want to maintain the original sound quality, should I consolidate with HiQ clip mode switched off???

question: did you get the phased sound when you played both track (one inverted) to check of something was wrong via phase test ? Or was the result after the consolidation phased by itself?

one thing I have found so far...

- note the master tempo is 120 bpm and the track tempo is about 118.1 bpm
- before consolidation the cencel out perfeclty what every ou do
- after consolidation they cancel out perfectly when you play them from start - but not when you start playing via the timeline, strange isn't it?

- all this does not happen when the track bpm is the same as the master bpm.

can you guys reproduce it?

The hats and hi end sound slushy and not as clear as the original AIFF, as if atefacts have been added in or something. Maybe phased is the wrong term.

When I listen to the original it is clear but the consolidate has lost some clarity.

I read that HiQ mode on clips should be used when warping etc (I do this for my DJ sets) but if I'm consolidating two 125BPM clips together with a project master BPM of 125 then maybe I should switch HiQ off.

HiQ mode only really comes into effect if you're pitching things up, I always leave mine on by default for instance. Make sure you turn warping off on the clips before you consolidate, and afterwards as well. Live likes to turn warping on automatically for you, and in some cases this can affect the audio quality, As long as you're project tempo is exactly the same as the audio clips, you don't need warping on.

any news, gillydj?
