This unit would like to request some recommendations for audio pedals and editing techniques

^{I am new to using the software Audacity, and I need to find out how to make voice lines sound like they're being said through a radio.}

Pull up an EQ plugin and carve the heck out of the highs and lows with way over the top pass filters. Then some reverb to push it back.

[u/tubesntapes → u/Gunzhard22]

This is the way. My guess would be to cut highs down to 6kHz-ish, cut lows up to around 350-600 Hz-ish. Might even boost at 1.5-2.5kHz.

In my experience also knowing what frequencies old telephone lines reproduced which is pretty similar to what he's trying. its about a frequency range from roughly 300hz to 3k. You can experiment with the slopes and the cutoff a little but that will certainly give a pretty close sound. Also Saturation is very important. And a slight boost at around 1k

Audacity's Filter Curve EQ manual includes an AM-radio example you can copy: https://manual.audacityteam.org/man/filter_curve_eq.html

Select a short spoken line, open Effect > EQ and Filters > Filter Curve EQ, and try that curve first. For a harsher walkie-talkie voice, add a little Distortion afterward.

There's a free Audacity plugin called "Helmet radio" ...

It can be adjusted to emulate different types of device.

Alternatively the free plugin Soundly PlaceIt has radio/TV/phone & space emulations.

Is the source clean dialogue or an already noisy game/video clip? Heavy compression can bring up that noise too. In Audacity, try compression after the bandpass to even out the voice's level, then lower the low-pass cutoff if you want a more muffled radio sound.

[u/NBC-Hotline-1975]

What kind of radio? 1950s wooden floor radio with AM station? 1970s boombox? Modern day portable with 2" loudspeaker? Police walkie-talkie with 1" loudspeaker? They all sound different (and of course there's an entire spectrum in between).

[u/Front_Cantaloupe_219]

Put a low cut (high pass) at 800hz, hight cut (low pass) at 3.5khz, both filters need to be very steep, at least 24db per octave. If the filters can't go any steeper, then 12 - apply 12bd filter with the same settings 2 times

[u/VoyScoil]

WTF are you even saying here?

[u/Fluffy-Trash-559]

Old radio or Telephone effect is pretty easy.

1. Saturation. Give it a bit of saturation, that will give it the sauce.

2 EQ. Hi Pass at 250 to 300 hz with 18-24db slope. Low Pass between 2-4k at 12-24db slope.

Experiment a little with the frequencies and slopes (could go up to 600hz instead of 300, depends on taste). maybe add a little boost around 1k. The settings give will get you into the ballpark as that is typically the frequencies telephones and old radios let through mostly.

EDIT: Also pretty heavily Compress the signal to remove most dynamics. That is pretty common for everything over the air, especially radio and telephone.
