Compress OGG

[johnv2pt0]

Is there a way to compress .ogg's or .wav's to cut down on .miz size? My missions are pretty big because of this because I like having all communications as sound files as opposed to text in front of your face. Thanks ~

Ogg is, generally, already compressed. Compression method can be one of many, however, up to you when creating the file.

For handling sounds for mission files, I'd generally suggest using Audacity: http://audacity.sourceforge.net/

Exporting in mono rather than stereo helps.

 

Also I prefer using the GSM 6.10 codec for wave.

Thanks guys I'll give these a go :)

Mh, interesting.

 

Why do you prefer GSM 6.1 vs. ogg?

 

Thanks.

Well for my mission on Station I used 55 very short audio files to form messages. With Ogg the total filesize is approx 2mb. With the GSM 6.1 codec I got it down to 1.3 mb. I realize its not much, but every little bit helps.

Also, depending on what audio program you are using (I used Audacity to create/save the files and if necessary, dBpoweramp to convert) you may also have the option to select the kHz.

 

I like GSM 6.10 at 22.050 kHz. Typical file sizes for a 3 second to 5 second radio call are 25-60 KB. You can save a little more file size using 11.025 or 8.000 kHz, but I think the quality gets too poor. I have over 100 sound files in a new mission, some up to 25 seconds/220 KB, and the .miz is 6 MB. Hasn't been a problem for anyone on our servers.

Joyride,

That's actually quite bad. Audacity is, I mean. You can get files 2 or 3 times smaller with AVS Audio converter. For example:

 

60 second sound file at 22 kHz same rate (good enough for music):

.ogg - 246 KB

.wav GSM 6.10 - 261 KB

 

60 second sound file at 11 kHz sample rate (MORE than good enough for radio, and good enough for music that is overheard over the sound of jet engines):

.ogg - 182 KB

.wav GSM 6.10 - 130 KB

 

Obviously, .ogg has some scaling problems as you reduce the sample rate, at least if AVS Audio Converter is any guide.

 

But your 5 second radio clip should really only need to be about 10 KB!

 

I've actually put 20+ minutes of sound into missions before... and the final file size significantly under 4 MB :)

 

One of the annoying things I've found with .ogg, at least with AVS Audio Converter, is that .ogg files often get the ends cut off of them during the conversion process :huh:. So I pretty much use exclusively .wav GSM 6.10.

I've used dBpoweramp (it's similar to AVS) to convert to 11 kHz and make them as small as you mention, but it's generally too much degradation for my tastes when you add in ambient/engine cockpit noises that the radio messages are competing with.

 

What I probably need to do it use less static/effects/crackle when I create the original voiceovers and let the modulation/degradation of converting to 11 kHz do the work ;-)

Hello to all..I have one question..

What is the maximum size of the ogg file so the mission can play it??

I tested one file about 4MB and it didn't play..Only when i cut it about to 124 kb played it..

 

Thnx...

[Megagoth1702]

Well I suppose so, since you already have found out. This is new to me but then again I never worked with anymore bigger than 200KB.

 

Just do some testing yourself. :p Also I can not think of anything that needs more than 1MB. :-/
