Noise reduction ear bleed.

I literally blasted my right ear last night. I was trying to perform the noise reduction tutorial in chapter 2 of the "Soundtrack Pro 2" Training Series. After applying the "reduce noise" function, the right right channel went from -12 to +27. It literally knocked me off my chair. I'm now afraid to keep my headphones on during playback. I checked the Apple-Support-Discussions forum and several people have had the same thing happen. Bug reports have been made dating back to February 2008, but no solution has been posted. Does anyone here at macProVideo.com know anything about this?

Hi Chasford,

Wow...I've not heard of this... Does this only happen when applying noise reduction to the tutorial files in chapter 2 of STP 2 Training series?

I haven't used noise reduction recently but have used it a few times and never had an issue.

Hope someone else here can shed some light on this.

Take care of your eardrums!

Yes this only happens when applying noise reduction. I'm new to STP2 so this is the only time I've had the problem, BUT, it makes me very cautious. I now take the headphones off before I play anything on STP2 just to make sure I don't get ear damage. This is not something you should have to do. Since the same thing has happened to others according to the Mac Forum it doesn't seem isolated. Here is another problem and it probably is related. When I open a clip in the noise reduce "heads up" pannel to toggle the "noise threshold" and "reduction", audio only plays out of the left channel. The left meter shows activity but the right meter is dead. This happens every time, unless of course if it decides to blast my right ear. When that happens the right meter goes through the roof! Unpredictable and it obviously makes it difficult to make adjustments. I'm new to this so I'm not sure if I'm doing something wrong, however I am following the tutorial very closely.

Right, I've just seen the thread on apple discussions you were talking about - sounds painful! It seems to only affect the noise reduction feature on mono audio files...?

Have you tried working with stereo files? One user reported that working with mono files causes the right meter to blast out noise...

Also, although not ideal when reducing noise, another user on that forum suggested selecting a short piece of the noise (1 to 2 seconds), then set noise print with only that selection highlighted. Apparently the audio doesn't jump up...

You can post this as a bug:
