Sound like a grunt from half life (radio)

Post by awkook »

How in goldwav can you make yourself sound like your over a radio or like grunts in half life?

If you're wanting a walkie-talkie effect, the first thing you need to do is filter out the bass (let's say below 100hz) and the high freqencies over 3.5khz.

For radio noise, you'll have to find some that's sampled and "mix" it in.

I don't game (except for Quake 1 and Postal 2), i have no clue what a grunt sounds like.

:wink: Find some noise... (If that's what you need.) You can try starting with Tool -> Expression Evaluator -> Presets -> Noise.

I don't know what a "Grunt" sounds like either, but usually your best bet is to start by mimicking the voice as best you can. Then, you can add some processing, if it helps.

To produce an effect that simulates the sound of a voice coming through a walkie talkie, try: Effect > Filter > Spectrum Filter > Highpass 1000Hz (From Presets).

For background noises, try some of the various Sound Effects distributors that can be found online. Sound Dogs is a good one, there are many others. Type the words "Free Sound Effects" into Google and go poke around until you find something that works.

yes..noise..for authentic sounding walkie talkies you'll need some noise..there's some background noise during transmission and generally a bit of static after each transmission (due to the squelch circuit)

the more bass you remove the more it will sound like it's coming out of a walkie talkie and not just quality of the resulting transmission (yeah don, i hadn't even thought of that)

Another thing is some SSB mistuning effect, it's a bit complicated, but possible, if ever you need to emulate that.
Try with a copy of the voice rather than the original. To avoid with too long a timing, because of the file size needed from step #one.

1) Resample the voice to 192000Hz
2) New window same length, same channels (mono/stereo) at 192000 Hz
3) in this new window, expression evaluator -> waves -> sine, 50000 inthe box "f", click ok
4) copy the result to the clipboard
5) back to the voice window
6) mechanize, clipboard option
7) bandpass filter 50300 to 503500
8) back to the sine window
9) redo the (3) with a setting slightly different for f (between 49050, 50050, 50024 for example)
10) copy to the clipboard
11) back to the voice window
12) mechanize, clipboard option
13) bandpass filter 300-3500
14) you can resample back to the "normal" rate.

It will not affect the pitch like the pitch effect which multiplies, it will addition or substract the frequencies of the harmonics instead, like for usb/lsb radiocommunications when the tuning of the transmitter and receiver isn't exactly the same (almost always the case).
:D

if you're talking about the squaking that occures when you're lacking a BFO for SSB transmissions...there's GOT to be an easier way than THAT, resampling to 192000 is..well...i see the point because it's how your directions are...but upsampling, and then resampling like that, it's not without it's own problems...192khz to 44.1khz is NOT a simple task and unless you filter it properly, goldwaves resampling system will not handle it well and you'l have lots of anti-aliasing.

a mistuned BFO simply changes the tone (but not the pitch). howver, you only see SSB on HF (shortwave) and you only generally see voice commuications on HF from ham operators. most walkie talkes anymore operate in the FRS band..or some other licensed band..but SSB isn't really used for voice comm out of shortwave.
