Re: [Avid-L2] odd random tone

Sounds like someone was trying to trick the DSLR Audio AGC with the 'ol tone trick. Google it, i can't explain it

But when I fast forward the clip in the Avid, the tone is there. Sound designer looked at the clip and found it carries a high level frequency that you can roll off with EQ. But her Pro Tools shows it. Stuff shot on 5D.

Odd though that it only came up on these interviews and nothing else I've played back today. but the volume was up at default level so when I pulled it down it went away. It was such a shrill I assumed it came from my playback speakers.

The interviews play fine in Quicktime. I import into After Effects and they play fine. But when I import into MC 5.5 I get a tone under the audio in channel one. Clearly there, loud enough to hear and for it to register on the Audio tool at about +6. It was not on a broll shot from the same interview when it was imported. Only on the interview. But as I said, no tone is heard when you play the original file. Only 2 tracks of audio, and track one has the tone after it comes into Avid. Sound engineer next door is very perplexed.
