Add AM radio effect to wav file

[bsyapril88]

Hey!

Does anyone know a process for making a wav file sound like it is coming from an AM radio?

Thanks

The Reader's Digest version is...

Download and run Audacity Version 1.3. You can have both versions as long as you only run one at a time.

Run the graphic equalizer and dip gently down below 300 and sharply down above 5000

Apply this compressor with the compression ratio cranked up to 7.7...

Record a live transistor radio next to a fluorescent light or an electric motor and mix that into the show.

Poof. Instant AM radio. Juggle or change the noise as necessary. The compressor is the closest I've ever heard to what a radio station actually uses.

Thanks for your help. Is there any quick substitute for "Recor[ing] a live transistor radio next to a fluorescent light or an electric motor and mix[ing] that into the show"? Will a simple white noise do the trick?

'Fraid not. FM radio has white noise. To really put the AM radio over, you have to come up with some sort of popping, periodic electrical interference either 50 Hz or 60Hz depending on your continent.


I know the fashion is Google > Edit > Upload, but I don't know of anybody that supplies that as a packaged effect. The easiest way is to record your own. One of these plugged between a transistor radio headphone output and your laptop or deskside should do it...

Your worse problem is the radio picking up too much junk from the computer. The best radio is one that will receive short wave. You can find any kind of noise you want up there. A radio that will receive aircraft bands will work, too. They're AM. Lots of pilots have portable radios that will do that.
