It's not A Number. It's sliding scale. 100dBSPL for fifteen minutes is considered one limit.

Scroll down for the chart.

You rarely want to capture peaking at 1. Live recordings are very unstable for volume control and any sound actually at 1 is distorted. The object is to peak just below one, but you do that in post, not during the capture. But that's not your problem. You are overloading something. Do you get the cl...

Oh, and Chris's Compressor does an amazing job of simulating a radio station compression. I bump the compression from .5 to .8 when I use it.

Yes, compression is called for, but I don't entirely agree with the 700 Hz drop. They didn't sound like telephones (300-3000). They had very good bass. No transistor radios in 1948. And it's also the difference between the spoof and the real thing. The effects can be minimal if the show is "Pep...

<<<"heterodyne whistle" >>> Exactly. Radio stations in the US are 10 KHz apart. During the day, everything works out, but at night, you can hear two stations right next to each other. From my childhood, WGY in Schenectady NY and WFAA/WBAP Dallas/Ft.Worth. 810 and 820 on your AM dial and bo...

This is a picture of a very simple AUP file. I added spaces so it looks good to humans, but you can open up yours with NotePad and read it. http://kozco.com/tech/audacity/aup1.jpg The name of the show, sampling speeds, file locations, etc, are all written in that file. If you move something and the ...

The Audacity AUP file is just the sound manager, it's not a sound file. It manages all the other files and folders that make up your show. Did you move anything to a different folder, delete any files or change the name of any files or folders? The AUP file keeps a very accurate internal listing of ...

I's not unusual for cheap sound cards to do this. There's no effort to synchronize the timer signals between the capture and the play back. They're designed to play YouTube and perform VOIP phone calls. No sync needed. This device uses ASIO drivers and Audacity only has very shaky support for that, ...

You can go well on your way to that effect with just the eq. That's how they did it, but they were spoofing the effect, not doing the real thing. Old Tyme Radio had announcers that took advantage of the response of the system by having very deep voices and slightly exaggerated pronunciation. No filt...
