In this video I'll be showing you how to make voices sound like they're coming out of a radio using a combination of two effects in audacity, equalization and high pass filter. Just to give you an example, here's my original clip. Simple audio test sample to sound like a radio. And here is the radio version. Simple audio test sample to sound like a radio. So let's get started. Equalization. In old versions of audacity there was an FFT filter, but that has subsequently been replaced by equalization. There are some presets here like AM radio. Simple audio test sample, but I don't find that they work very well. Flattening it out again. Equalization allows you to amplify some frequencies while dampening others. So I'll draw a simple curve here. We want it to be around 1000 Hz and a positive 12 dB. See how the line moves? And then go over here to about 10,000 and negative 12 dB. Click OK. See how the waveform got much bigger? Here's a preview. Simple audio test sample to sound like a radio. And so we want to remove some of that extra noise we just put in. I'll use a high pass filter. And 6 dB over here. 0.7 rolloff. And the cutoff frequency here should be 2000. Simple audio test sample to sound like a radio. That's pretty good. If you want to you can repeat the steps with equalization. OK. And then do another high pass filter. And you get something like this. Simple audio test sample to sound like a radio.
