So original SLN compiled. I tried it, it worked. But when I am triing to compile it under \clr (which is critical for me). So what I tried was to try playing with compiler options but after fixing general visiable errors I ended with this 3 Error 10 error LNK2028: unresolved token (0A0003BF) "extern "C" int __cdecl _CrtDbgReportW(in...
Whats the best way to play a sound using OpenAL in xcode 3.2.2 on a 3.1.2 SDK im pulling my brains out at the moment. I've followed ben brittel and mike daley's tutorials on openAL and ive implemented all the things needed to play sound. Basically i creaed a sound manager class with the help of their fantastic tutorials. The only proble...
I have a project that uses OpenAL. The project is built against the 10.5 SDK, and the version of the OpenAL.framework in 10.5 causes some problems. I want to link to a custom-built version of the OpenAL.framework that resides in my source tree. However, Xcode resolutely refuses to do this. No matter what I try, it insists on linking to ...
Hello, I've recently been trying to incorporate an intensive sound management class, where sound playback precision is a must. What I'm looking for is the option to load a sound, set the playback starting position (or playhead), play for a certain time, pause the sound, set the 'playhead' position to a new interval and resume playback a...
Hey everyone, I was wondering if someone could point me in the right direction to creating a function in my openAL singleton class that returns the current time of the sound. Any Ideas? Thanks! (Current time 'while the sound is playing') ...
For simplicity, let's say I have 3 tracks. One always plays, then occaisionally one of the others will also play: [----------Background track----x------] [------------"Good" track------x------] [------------"Evil" track------x------] So at time "x" you will be hearing background+(good/evil), depending on what the player is doing. The ...
Hi all, I have a problem with the combination of OpenAl and the MPMoviePlayerController. I registered the AudioInterruptionLister in my OpenAl Setup process. When I start a video the listener receives the AudioListenerInterruptionStarts, but when the movie ends I do not receive the AudioListenerInterruptionEnd trigger. // Register cal...
I'm using Core Audio / OpenAL to play CAF audio files. From Apple I know that the best file format is this: Core Audio File Format (CAFF), mono, 16-bit @ 44,1 kHz So I launched Soundtrack Pro 3 and saved an WAV file as an "Core Audio File" with 44,1 kH, 16-bit integer. When I play it back, it is strongly distorted and has a horrible q...
How to adjust the volume of a sound in OpenAL? ...
Hello, For the 3D iPad app I am writing I want audio to increase/decrease in volume as a single virtual listener turns towards/away-from sound sources. The listener is always stationary. The listener can only rotate. The sounds are always stationary. The sounds fill a sphere of directions around the user. The sounds are all of equal dis...
I am making an application for iPhone/ipod Touch. In that application I am recording the voice of a human storing it in a file in NSTemporaryDirectory() and then playing it. So far I have used AVAudioPlayer and AVAudioRecorder but after some time when I record it simultaneously it plays the sound I don't know why? And more over my applic...
Is it possible to use the iPhone's hardware accelerated decoding of mp3s and AAC when using the OpenAL library? I suppose there are two possible approaches if this is possible. iPhone specific OpenAL extensions. iPhone APIs to decode audio into raw bytes. I have two specific use cases. Completely decode a short sound bite. Piecewise ...
I'm writing a sound library, for the iPhone, that uses OpenAL. The app generates a unique buffer id for each sound, during startup. The problem that I'm having is that OpenAL is unable to generate more than 1024 buffer ids. I would've thought that the total number of buffer ids would've been limited by memory, not by some pre-determin...
Hi, Please tell me how to install openGL (with GLUT) and openAL (with ALUT) in ubuntu lucid lynx. I tried installing Mesa 7.8.2 using configure and make (the method told in www.mesa3d.org), but it is not installing anything. X.org's X is installed in my system, but there is no /usr/X11R6 directory. Is that a problem? Please help me soon....
Can anyone tell me why the volume becomes lower when I make the pitch higher in openal? The higher the pitch, the lower the volume..... alSourcef(source, AL_PITCH, 1.2f); alSourcef(source, AL_GAIN, 1.0f); with this setting, the volume is still very very low. is there a way to cheat it to make the gain above 1? Maybe this has somethin...
I am using the ObjectAL library to play 50 odd buffers through 32 sources. I use the ObjectAL sourcepool to give me available sources. What I find is that sometimes I get a source back that does not play. I believe I am resetting everything on the source and associating a new buffer. What I have noticed is that after a call to alSourc...
I tried alBufferf (myChannelId, AL_MAX_GAIN (and AL_GAIN), volumeValue); and got error 0xA002. ...
What should i do? I have some 512x512 png. I compressed them to PVR (which results terrible quality), and I'm preparing to compress the PNGs with pngcrush tool. The PVRs have about 2x-x larger filesize than the PNGs, maybe I can experiment with JPG files. Are the images stored in a compressed state in memory? Or compression counts only ...
