I’d like to use it as Flight simulator trip when pilot talks with ATC in old plane. So old radio. I mean is there effects what I like to use? Earlier I used old phone to record speech and when I played it with it it sounded good because old phones was quite poor loudspeaker but now I don’t have that old phone anymore.
Try experimenting with the Graphic Equalizer. Start by cutting the low frequencies, maybe below 300 Hz. With real world communications radio (and AM) the highest frequencies are lost too, but that affects intelligibility.
You can also add some hard-clipping distortion.
And maybe add a little noise (maybe pink noise or white noise). Create a new track and generate the noise in that track. You’ll have to lower the noise relative to the the voice, maybe around -20 to -30dB.
That’s good plugin. Thanks.
