VoiceHook - Developer preview of something.

This plugin hooks the broadcast of voice chat through the server, decompresses it with Valve's audio codecs, passes it onto other plugins that have registered a listener and then re-compresses the data.

WARNING: For TF2 and other games using the Steam audio system, you need to set the sv_use_steam_voice convar to 0 if you want decompression to work.

The interface is quite simple:

Code:

#define VOICE_INTERFACE "VOICE_INTERFACE_002"



class IVoiceListener

{

public:

        // In raw mode, nSamples = bytes;

        virtual void OnVoiceBroadcast(int client, char *pVoiceData, int *nSamples)

        {

        }

};



class IVoice

{

public:

        virtual void AddVoiceListener(IVoiceListener *pVoiceListener) = 0;

        virtual void RemoveVoiceListener(IVoiceListener *pVoiceListener) = 0;

        

        virtual void AddRawVoiceListener(IVoiceListener *pVoiceListener) = 0;

        virtual void RemoveRawVoiceListener(IVoiceListener *pVoiceListener) = 0;

};

and can be acquired with the following code:

Code:

IVoice *pVoice = (IVoice *)g_SMAPI->MetaFactory(VOICE_INTERFACE, NULL, NULL);

I'm fed up with typing, so have a load of files:

The actual plugin: Attachment 111530 Attachment 111531
Source for a SourceMod extension implementing a simple recording command: Attachment 98591
A SourceMod extensions that has a simple forward for SourceMod plugins:
- Source code: Attachment 98590
- Compliled copy for plugin devs to play with: Attachment 111528 Attachment 111529
- Simple test plugin: Attachment 98587

You'll need to copy vaudio_speex.dll from Steam\steamapps\<account name>\<Source 2009 using game name>\bin\ (Linux users can get the Linux one from here) and copy it to orangebox\bin in your server install.

TO-DO List:

Further reverse engineer the broadcast function, if it can be completely replaced we'll be able to avoid the terrible voice management functions.
Allow interface implementors to block the function.
Implement a method to get IServer, so we can broadcast arbitrary audio to clients.

Needs moar source code :P

Re: VoiceHook - Developer preview of something.

Sorry, why would someone change the voicedata in a plugin ?

But it sounds great :) I always wanted to do this.

A few random ideas that have come up from people:

Decrease or increase the volume of a client's voice audio.
Pitch-shift it or other audio effects.

I really don't know tbh, it was a requested feature :).

Re: VoiceHook - Developer preview of something.

Sampling rate? How many bits per sample?

Re: VoiceHook - Developer preview of something.

use voice audio channel stream mp3?

From voicerecord_ext:

Code:

WAVEFORMATEX g_VoiceSampleFormat =

{

        WAVE_FORMAT_PCM,        // wFormatTag

        1,                        // nChannels

        11025,                        // nSamplesPerSec

        22050,                        // nAvgBytesPerSec

        2,                        // nBlockAlign

        16,                        // wBitsPerSample

        0                        // cbSize

};

Re: VoiceHook - Developer preview of something.

And why no ability to create audio data from scratch? I wanna make my bots talk. :D

What about a voice recognition thing where it can pipe the voice to another program and based on what it detects execute server-side commands like ban people for saying the N word.
