Here it is. Real time capture. All I was doing was pressing space-bar stop and start. I took the pauses out where I tried moving things around the screen. The end piece is a music proof. It was a download. Thats the whole pathway from iTunes in the Mavericks machine to a recording on my Mini "T...

I can reproduce the problem — in either Audacity 2.0.3 or 2.0.5. Doesn't appear to make any difference. I could have done with a test that didn't have crackles and pops as part of the performance..... Just once I got a playback destroyed — digital garbage for the first second and then it straightene...

I have the draft zip. How do I tell if the Project starts before zero?

Weighting would not normally make a huge difference

Not on voices, no, but dance clubs live on the difference. All that shirt-moving bass assault doesn't register.

C weighing doesn't go all the way down, either. Odd they picked Z. Maybe they were trying to filter out (to to speak) all those people with significant technical problems. If I was going to choose a test to trip up 90% of voice producers, that would be it. Can your office off the hallway just past t...

Is it really a "specification" without specifying weight? Without a weight specification, I assume either C (minimal) or Z (no weighing). Although it could be argued that legal and hazard specifications are always A, and those readings are always lower. In A, you might not need the High P...

By my measurements, the peak level is -1.0 dB which is just a little too high. That is easily fixed by limiting to -3 dB. That happened when I bumped up the compression. The last Chris setting down is Maximum Amplitude. By my measurement, the noise floor is about -47 dB rms, which is just a little ...

Continue on your merry way. Nothing to see here. The point of the technical discussion is that the ACX specifications are too technical for the average reader/performer. It's possible that a relatively simple application of Chris's Compressor is all you need. There's nothing simple about what Chris'...

It might do that after you split stereo tracks to mono. If you have a left-only stereo show and make an MP3, it will make an MP3 with you on the left side. I don't think there's an option to make a mono MP3. I think that's a feature request.
