Pro Tools levels - what's going on?
I needed to to make slight adjustments to the speed and pitch of a
badly-recorded acoustic '78' (which was actually wavering from 80 to about 85 rpm), so I imported the 16-bit mono file into Pro-Tools 5.01 to use the pitch-changing plug-ins. The original file had about 2db headroom, but when I Bounced it back, it was over-modulated and had horrible clipping. As a check, I recorded a 1Kc/s tone at 10dB below peak, imported it into a 16-bit Pro-Tools session and then Bounced it straight back again without altering it in any way. The result was 3.56 dB louder. What is going on? -- ~ Adrian Tuddenham ~ (Remove the ".invalid"s and add ".co.uk" to reply) www.poppyrecords.co.uk |

It was a single mono AIFF track and I exported it in mono.. I had previously suspected that something like this was happening a long while ago, but then I was using multiple tracks so I assumed it was due to the tracks adding. This time there were no other tracks and I made no changes to the single track at all, it should have come back out bit-for-bit accurate. -- ~ Adrian Tuddenham ~ (Remove the ".invalid"s and add ".co.uk" to reply) www.poppyrecords.co.uk |
