It's a work in progress, but it's functional now.

Nice to see a FMOD sound manager for Ogre!

Very very nice .. I'll try ASAP ..

DrPain · Post by **DrPain** » Mon Feb 06, 2006 1:34 pm

I hope you find it useful.

A few minor changes were made to the Wiki page (not the source).
Just some clarifications and got rid of a -1 which should have been INVALID_SOUND_CHANNEL.

I tried the SoundManager yesterday. Very useful, thanks

I found a minor problem with the stdafx.h. It includes the mmsystem.h ( or something like this I don't remember the header file name exactly sorry) which defines a PlaySound function that conflict with SoundManager::PlaySound. It raised a Link error. Probably I forget to do something, but I comment out the #include stdafx.h and all works fine.
Very nice work DrPain, thanks a lot.

@DrPain: are you planning to add a wrapper for the FMOD geometry engine for sound occlusion?

DrPain · Post by **DrPain** » Sat Feb 11, 2006 4:18 pm

Hmmm.. I've just really started using it myself. I'll have to look into that.
I'm working on fixing a crash issue at the moment (I believe unrelated to this manager), but after that's resolved, I'll take a look at it.

Anyone know if that feature is a CPU hog?

I do have a new version to upload. But I want to resolve the crash issue first to make sure it's really not a SoundManager problem.

Maybe you could replace your hard-coded access code with this (You assume a fixed resource group and the code is limited to plain file access, as discussed in another thread):

Code: Select all

	FMOD_RESULT F_CALLBACK SoundManager::FModOpen(const char *pFilename,int bUnicode,unsigned int *pFileSize,void **ppHandle,void **ppUserData)
	{
		try
		{
			Ogre::String *pGroup = new Ogre::String(Ogre::ResourceGroupManager::getSingleton().findGroupContainingResource(pFilename));
			Ogre::DataStreamPtr dataStreamPtr = Ogre::ResourceGroupManager::getSingleton().openResource(pFilename,*pGroup);

			if(dataStreamPtr.isNull() == true)
				return FMOD_ERR_FILE_NOTFOUND;

			(*pFileSize) = dataStreamPtr->size();
			(*ppHandle) = new Ogre::DataStreamPtr(dataStreamPtr);
			(*ppUserData) = pGroup;

			dataStreamPtr.setNull();
		}

		catch(Ogre::Exception e)
		{

			return FMOD_ERR_FILE_NOTFOUND;
		}

		return FMOD_OK;
	}

	FMOD_RESULT F_CALLBACK SoundManager::FModClose(void *pHandle,void *pUserData)
	{
		Ogre::DataStreamPtr streamFMod = (*((Ogre::DataStreamPtr *) pHandle));

		streamFMod->close();

		delete (Ogre::String *) pUserData;
		delete (Ogre::DataStreamPtr *) pHandle;

		return FMOD_OK;
	}

	FMOD_RESULT F_CALLBACK SoundManager::FModRead(void *pHandle,void *pBuffer,unsigned int nSize,unsigned int *nRead,void *pUserData)
	{
		Ogre::DataStreamPtr streamFMod = (*(Ogre::DataStreamPtr *) pHandle);

		(*nRead) = streamFMod->read(pBuffer,nSize);

		if((*nRead) != nSize)
			return FMOD_ERR_FILE_EOF;

		return FMOD_OK;
	}

	FMOD_RESULT F_CALLBACK SoundManager::FModSeek(void *pHandle,unsigned int nPosition,void *pUserData)
	{
		Ogre::DataStreamPtr streamFMod = (*(Ogre::DataStreamPtr *) pHandle);

		streamFMod->seek(nPosition);

		return FMOD_OK;
	}

It still avoids the full scale solution with defining an own ResourceManager and Resource class, so it isn't able to precache the sample. At least it can read the files from all supported backends. Initialize it after the init call with:

Code: Select all

pSystem->setFileSystem(FModOpen,FModClose,FModRead,FModSeek,2048);

Declarations (For copy and paste):

Code: Select all

		static FMOD_RESULT F_CALLBACK FModOpen(const char *,int,unsigned int *,void **,void **);
		static FMOD_RESULT F_CALLBACK FModClose(void *,void *);
		static FMOD_RESULT F_CALLBACK FModRead(void *,void *,unsigned int,unsigned int *,void *);
		static FMOD_RESULT F_CALLBACK FModSeek(void *,unsigned int,void *);

Sorry, if there are any typos, I ripped the code out of my source code, which handles the rest a bit different.

I think in SoundManager.cpp in CreateSound it should be

Code: Select all

case SOUND_TYPE_3D_SOUND:
         {
			 result = system->createSound(fileName.c_str(), FMOD_DEFAULT | FMOD_3D | FMOD_HARDWARE, 0, &sound);
         break;
         }

where FMOD_3D and FMOD_HARDWARE are added. Just because a sound isn't looped doesn't mean it shouldn't have 3D effects.

Also, I am having a wierd bug with the channels it seems. When I play too many sounds too quickly my program crashes. It seems to me that it takes a bit before the manager decides a channel is not needed anymore and if the channels fill up (to 32?) there is a crash.

Hopefully this thread isn't dead.

Isomorphic · Post by **Isomorphic** » Thu Mar 16, 2006 12:24 am

Alright, I fixed the bug, not that I am really sure what was causing it. In

SoundManager::PlaySound(int soundIndex, SceneNode *soundNode, int *channelIndex)

This *channelIndex should equal -1 when it is an invalid sound channel, but for some reason, instead it equals some large number, which is the same during the run, but changes from reboot to reboot. So now, it does a quick check to see if the number is in the proper channel range.

Code: Select all

if ((*channelIndex < 0) || (*channelIndex >= MAX_SOUND_CHANNELS)) *channelIndex = INVALID_SOUND_CHANNEL;

Sorry for the long delay. I've been immersed in other areas of code and am just getting back around to this.

SunSailor -
I'm actually toying with your idea of making the SoundManager a full-blown resource manager. It'll probably be a few weeks before I can get to that, but I am leaning more that way at the moment.

Isomorphic -
I've tried all kinds of scenarios to get it to crash with no luck.
Are you initializing the channelIndex to INVALID_SOUND_CHANNEL as instructed in the Wiki?

Mikachu · Post by **Mikachu** » Fri Mar 31, 2006 1:14 am

Good job.
I don't know if it is implemented in FMOD, but, if so, could you add more controls about sound intensity and pitch?
For example, a spaceship reactor sound pitchs up and grow in intensity when accelerating.

tobie · Post by **tobie** » Mon Apr 10, 2006 10:15 pm

-Mikachu

FMOD supports several effects (DSP). Here's how to add an echo effect to a channel.

Code: Select all

FMOD_RESULT result;

result = channel->addDSP(dspecho);
ERRCHECK(result);

Where dspecho has been defined as

Code: Select all

FMOD::DSP	*dspecho = fmodSystem->createDSPByType(FMOD_DSP_TYPE_ECHO, &dspecho);

The effect can then be changed using setParameter:

Code: Select all

result = dspecho->setParameter(FMOD_DSP_ECHO_WETMIX, 0.3f);
ERRCHECK(result);

The SoundManager now supports loading from Archive files (zip files, or theoretically any other ResourceManager supported format).

This is brand new code. It has been tested, but not a lot.
But I figured it's better to get it out there and have the masses bang on it and report any problems.

A bug in PlaySound() was fixed that would prevent the same sound from re-playing when in the same sceneNode.

This is appreciated!

Thank you for your numerous contributions so far!

Hi!

As I'm still looking for a working sound manager I tried your's ... but it won't compile...

------ Build started: Project: Ogre_simpleSurround, Configuration: Release Win32 ------

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

the
'syntax error 'constant' ' is pointing to the header's 'using namespace Ogre;'

I don't get it....

Post by **jacmoe** » Thu Apr 13, 2006 9:26 pm

Looks like we should add a line before the using namespace Ogre line:

Code: Select all

#include <ogre.h>

Katzenjoghurt · Post by **Katzenjoghurt** » Fri Apr 14, 2006 3:03 am

thx jacmoe ... alright, alright ... I'm a beginner.

Yet, I'm still confused... including ogre.h in the SoundManager shifts the "syntax error : 'constant' " to OgrePlatform.h ...

How do I properly integrate the two soundmanager files?

Post by **jacmoe** » Fri Apr 14, 2006 3:34 am

I had to insert an #include <windows.h> just before the include <ogre.h>.

Katzenjoghurt · Post by **Katzenjoghurt** » Fri Apr 14, 2006 12:12 pm

Hmmm.... this didn't do anything good now ...

Post by **jacmoe** » Fri Apr 14, 2006 1:36 pm

Make sure that you are using the newest FMOD.
It works perfectly here. Provided that you are using it in an OGRE application.

Katzenjoghurt · Post by **Katzenjoghurt** » Fri Apr 14, 2006 2:00 pm

I downloaded FMOD just yesterday.... Ogre is 1.2.0

.. it's just, that something goes wrong with the namespace thing.

When including ogre.h in the soundmanager.h the header compiles fine .... but then VS gives me a syntax error : 'constant' at OgrePlatform.h right were Ogre namespace is defined ( namespace Ogre { )

including windows.h in the soundmanager.h didn't make a change...

----

ARGHH! silly me!
I renamed the SoundManager.h to SoundManager_FMOD.h ... and forgot to rename the cpp file as well.

This kind of thing happens all the time - and we are spending way too much time on such stupid mistakes, because we think the problem is bigger than that.

I second that!

... oh well... I better shouldn't tell you that I'm a computer science student in his 6th year. Nah. I rather keep this for me.

...and it goes on and on. (yeah ... as if shame wouldn't be big enough already.... I'm stuck once more)

The sources compile now, but the test program crashes when calling

nightLoop = soundMgr->CreateSound(String("whatsdiversity.wav"));

in this line of SoundManager.cpp

int SoundManager::FindSound(String &fileName, SOUND_TYPE soundType)
{
int vectorIndex;
int vectorCapacity;
SoundInstance *nextSoundInstance;

=> vectorCapacity = soundInstanceVector->capacity(); <=

The wav is in the exe Folder. I tried the full path as well.... but I keep getting the same unhandled exception.... no matter if I type in a nonsense filename or the filename of any existing wav.

Anyone had this crash as well?
