[C] PSP Advaced Audio Library

[Arshia001]

After solving a number of stability issues,I've finally decided that PSPAALIB is ready.I don't say it's completely bug free,but it should work fine for the most part.

For those of you who don't know,the PSPAALIB is essentially an audio library,which has the following features:

Plays MP3 via the PSP's Media Engine,
Plays MP3 via LibMAD,
Plays WAV,
Plays AT3,
Plays OGG,
Plays up to 8 files at once,using pspaudio,
Supports a number of effects,such as Play Speed,Doppler effect,etc.
Is easy to use.(Minimum of 2 function calls to play a file.)

Installation:
Copy PSPAALIB folder to your project's folder,include pspaalib.h,and add the information in my makefile to yours.Read the included Readme for information on how to use the lib.

I'm hoping to have a sample up in a few days.

Any feature requests,bug reports,suggestions and comments are welcome.

P.S.Since the last topic was more like a progress report/discussion thread,I decided to create a new topic.

-------------------------------

Thanx to Zack,a very important bug in the lib has been successfully sent on a one-way train to the depths of hell.
Also fixed(Thanx to Zack for the bug report again) is an issue with threading which caused the lib to stop functioning after multiple calls to AalibPlay().
So,that means we now have update 2.Enjoy.

-------------------------------

And yet another update.This time,I expanded the WAV player.It now supports 8/16 bits per sample.In the past,it supported only 16,and would try to play others,but failed miserably.It will throw a warning now instead.That's update 3,and in one day...You're a bug-finding machine,Zack.

-------------------------------

I've been meaning to do this for a very long time now.Where you can use AalibSetVolume() to decrease the volume,you should also be able to increase the volume over the maximum,and now you are.With the new AMPLIFY effect,you can amplify files that are recorded at a low volume.Files that are recorded right can't play louder,and you'll get lots of static if you try it.

Hi,
I was reading through the other thread, and it may show lack of imagination on my part,
but why would anyone want or need to play more than two mp3s at once?
I can understand a background mp3 and wav sound effects for game apps, but that's about it.

Good work BTW
Art.

[Arshia001]

More than 2 MP3's would prove unnecessary.You will need two to create crossfading effects,or simply to avoid loading them each time you need them if you use ONLY two in your whole app.Your idea of wav sound effects is exactly what this whole thing is about.

Thanx.

Hi guys ...

I'm a new guy trying to get something out of his psp
Glad to meet you all

By any chance, has anyone got Arshia's audio lib hosted somewhere ? Seems the forums lost the file, and i can't seem to get 'libaudio2' ( newer sound lib ) to compile ...

Thx a bunch to anyone !

Umm WTF?
Not changing anything I Get This:

I looked at the 'AalibChannelData' Struct and it does infact have all those members the compiler said It didnt

What Is going on???

[mowglisanu]

Why would you think removing the line would fix it?
You should rename bool to something like boolean, that might be some work since it looks like its in all the files.

[stinkee2]

to be honest, I have no Idea... I was and still am really tired. I Need Sleep.

thanks for the help, Ill try that tomorrow

[Arshia001]

Say,if gcc is a C compiler,why does it keep telling people bool is a pre-defined C++ type?Besides,I had no problem compiling the code myself,and there aren't exactly a thousand compilers for the PSP...Could it be that -lstdc++ is causing this?
Anyway,I can't be sure,but I think renaming bool to something else is sure to fix the problem.Could you tell me if it does?

[mowglisanu]

>Say,if gcc is a C compiler,why does it keep telling people bool is a pre-defined C++ type?

I'm sure he was working on his Easy Graphics - Physics Library which is in C++.
You could also try including stdbool.h.

Yes, I was actually. I should have started a seperate project for this to test it.

this is a little off topic but, where would I start for Implementing Audio loading & Playing into my Library?
should I integrate a pre-made library (Giving credit where credit is due of course)?

also, Do you think that what Im doing is a good Idea? or should I just stop.

[Arshia001]

I don't really think you can make it any easier than we (mowgli and me) have made it.You should concentrate more on finishing what you've started than trying to add to your to-do list.I tried this,and every single time when I kept thinking of new things to do,I ended up doing nothing at all.If you ask me,keep working on your gfx/physx lib(specially the physx part).That's what we really need around here.
