Imported Master clipping in Pro Tools in 44.1 session???

Hey dudes,

I've been mastering tracks in Pro Tools at 24-bit, 48Khz. Sending the tracks out to a hardware L2 and dithering them to 16-bit, then bringing the tracks back into Protools digitally.

I've then been exporting the recorded tracks/regions and bumping the sample rate down to 44.1Khz (in this session the tracks aren't peaking).

If i import the exported tracks back into a 44.1 khz pro tools session, they are audibly clipping, the top end has gotten crunchy and the meters are peaking.

If i import the same 16bit 44.1khz track into a 48Khz pro tools session, the track sounds better and the meters don't peak.

Why is this so? Anybody have any ideas?

From your description, It sounds like your adding dither before you are doing your sample rate conversion. Have you tried adding dither after your src, as your last step?

Also, you are doing your src after limiting which will cause intersample peaks, as you describe.

Basically if you src before limiting and then dither this will not happen.
