Custom sound clips

[Apache600]

Hey guys,

Just started making some missions the other day. Having a ton of fun with all the possibilities.

Anyway, one thing i can't seem to figure out is how to add a custom sound file.

My objective would be to place a trigger around a small battle, and as the player aircraft enters the trigger area, a radio call is make from the ground forces being attacked. I was hoping that I could make a sound file pretending to be the ground forces, and inform the pilot of our location, direction of enemy fire, etc. I'm just not sure how to add that in.

Anyone able to help with this? it would be greatly appreciated.

Thanks

Its a trigger action called "sound to (coalition, country, group)." This will allow you to choose any recognized sound file. I Think .WAV and .ogg are supported, possibly others.

Hey Apache!

This is totally possible, and very easy to do.

 

1- create your trigger zone along the flight path, and name it something easy to recognize

 

2- open the "triggers" menu

 

in column one- 1 ONCE (triggername, NO EVENT)

in column two- PART OF GROUP IN ZONE (player group, triggerzone)

in column three - SOUND TO ALL (yourfile.wav)

 

All the items in parentheses will be selected from drop-down menus.

Here's a copy of my post I made in another thread about creating "radio" voiceovers.

 

I am an audio engineer by profession, so I thought I could add a little information, and a couple alternative options for your sound video.

Quick and dirty explanation:

Recording a mono, 8-bit .WAV file at an 8,000 KHz sampling rate will reduce the file to a manageable size (about 600KB/minute of audio) and naturally produce the desired filter effect! This is a nice, quick way to get reasonably convincing "radio" VOs without jumping through hoops converting files and applying effects.

 

SCIEEEEENCE:

The way analog audio works is by capturing a representation of the sound wave (which is the movement of air) and translating the image of that movement into another medium, 1 to 1.

 

The way digital audio works, is a file has a sampling rate, and a bit rate. The sampling rate is how many times per second a picture of the movement of air is captured, the bit rate is how detailed that picture is.

Both of these factors contribute to how "natural" digital audio sounds (but we won't start an analog-vs-digital debate, that's for another forum haha) but most notably with respect to what we're discussing here, they drastically affect the file size and some key characteristics of the sounds themselves.

 

A higher frequency sound like a bird chirping, or a whistle, vibrates the air much faster than a lower frequency sound like a bass drum.

 

Keeping this in mind, a digital audio recording with a lower sampling rate cannot capture higher frequency sounds, as the "pictures" it is taking of the movement of air are too infrequent to capture the information. Imagine trying to watch a car drive by at 90mph, only opening your eyes once every 5 seconds. There's a good chance you'll never see the car.

 

BUT WHAT DOES THIS HAVE TO DO WITH MY DAMN MISSION VOS, you ask?

 

The "AM radio" effect you are applying is a filter, which removes the low and high frequency content from the voice. Assuming most people are using crappy desktop or webcam computer mics, the low frequency content should already be absent, or can easily be made absent by holding the microphone a little farther away from your mouth (this is called the proximity effect, and is another lecture )

 

Recording your .WAV file at 8KHz will mean your file is tiny, and also that the high frequency content in your voice is naturally cut off because the medium is incapable of capturing it. Reducing the "detail" of the picture from 16-bit to 8-bit will add a "grainy" quality to the voice.

 

And voila, instant, reasonable VOs with things you already have, and windows sound recorder.

 

Now, that being said, taking a more invested approach like Ranger and using a multitrack program to add background noises for flavor, and effects for your voice, will give you much finer control over the final product. I just thought I'd offer this one for anyone who finds that idea intimidating.

 

 

2ND EDIT:

Just a few other resources that I've found helpful.

 

Voxal Voice Changer - http://www.nchsoftware.com/voicechanger/

This will apply effects to your microphone in real time, so all you have to do is set up a template and it will automatically apply them whenever something uses your microphone. It is an unquestionably cheap looking program, and not of professional quality by any means, BUT it's easy to use and will do what you need. There is a free 15 day trial period, and then the full version of the program is something like $20.

For my "pilot" VOs on my campaign, I apply a low pass filter at 4KHz, a high pass filter at 1KHz, and 100% distortion at -32db.

You'll also have access to pitch shifters. Tuning your voice a tiny bit in either direction will still sound fairly natural and is a great way to get more out of your voice if you're trying to sound like a bunch of different people.

I know it's kind of hilarious that I'm using this rather than a professional audio program, but all my audio stuff is on a different OS and porting crap back and forth between machines is a PITA!

 

Online .OGG Converter - http://audio.online-convert.com/convert-to-ogg

For when it's still just too damn big. Just point to your file, and the webpage will spit out an .OGG for you to download.

If you'd like to add a response from the pilot to the comm from ground forces, simply add "FLAG ON (flagnumber)" to the third column of the first trigger.

 

Then, create another trigger that looks like this

 

In column one - 1 ONCE (triggername, NO EVENT)

In column two - TIME SINCE FLAG (flagnumber, lengthofsoundfile seconds)

In column three -SOUND TO ALL (sound2.wav)

 

Use the length of the first radio message plus a couple of seconds (an instantaneous response will not sounds natural) to determine how many seconds to delay your second message.

Holy cow, thanks for the responses! Looking forward to giving this a shot when I have time in a few days. Thanks again !!!! I'll report back with the results :)

Happy to help! Also, here's the thread where that post came from, which has an awesome video series from Ranger79 on the ins and outs of the ME.
