Topic: BASS for iOS (iPhone/iPad)

[Ian @ un4seen]

iOS versions of BASS and the BASSDSD/FLAC/HLS/MIDI/OPUS/WEBM/WV/mix add-ons are available here:

   www.un4seen.com/files/bass24-ios.zip ^{(updated: 23 Sep '21)}

The BASSenc and BASSenc_FLAC/MP3/OGG/OPUS add-ons are available here:

   www.un4seen.com/files/bassenc24-ios.zip ^{(updated: 25 Jun '21)}

The headers and documentation can be taken from the packages on the BASS page. The examples haven't been ported yet, but the BASS calls will be the same as on other platforms. If anyone would like to port any of the examples, that would be very welcome

These add-ons are also available:

   www.un4seen.com/stuff/bass_ape-ios.zip
   www.un4seen.com/stuff/bass_mpc-ios.zip
   www.un4seen.com/stuff/bass_tta-ios.zip
   www.un4seen.com/stuff/tags-ios.zip
   www.un4seen.com/stuff/bass_fx-ios.zip

Note that BASS and the add-ons are provided as static libraries, because dynamic libraries aren't allowed on iOS. The libraries are in XCFramework form, including support for armv7/armv7s/arm64 "device" builds and i386/x86_64/arm64 "simulator" builds. To include BASS in your project, the XCFramework should be added to the "Link Binary With Libraries" build phase. If you're using an old Xcode version without XCFramework support then you can link directly with the library inside the XCFramework instead. You will also need to add the following frameworks to the project: AVFoundation, AudioToolbox, SystemConfiguration, CFNetwork, Accelerate, CoreMIDI (if using BASSMIDI). The "Other Linker Flags" setting should also include "-lstdc++" when using BASS_FX or BASS_APE. The "Enable Bitcode" option should be set to "No".

The plugin system is supported, but a little differently due to the lack of dynamic libraries. For example, if you want to load BASSFLAC and BASSWV as plugins, you can do so like this (after adding the BASSFLAC and BASSWV libraries to your project):

Code: [Select]

extern void BASSFLACplugin, BASSWVplugin;
BASS_PluginLoad(&BASSFLACplugin, 0);
BASS_PluginLoad(&BASSWVplugin, 0);

The BASS_CONFIG_IOS_SESSION option can be used (with BASS_SetConfig) to configure the app's audio session. An app can handle the audio session configuration itself (see AVAudioSession) by setting that to BASS_IOS_SESSION_DISABLE. See the documentation for details.

Support for use with .Net is included in the BASS.Net package.

In there is any C# coders that use MonoTouch framework for developing iPhone apps, I'm happy to tell you that BASS for IPhone works with MonoTouch (yes you can link static libraries in MonoTouch). I can make a simple MonoTouch example if needed.

Nice Job, Next for BlackberryOS

A Bass.Net version for iPhone is comming soon...

What the Licensing/Cost  of the iPhone version ?

[Ian @ un4seen]

Licensing is the same on all of the supported platforms. In the case of the Shareware licence, an amendment has been made primarily with the iPhone App Store in mind, whereby the product doesn't actually have to be shareware (eg. "try before you buy") but the price limit is lowered to 10 Euros then.

I'm having a few issues with a adaptation of the net-radio example.
I`ve successfully adapted it to iPhone and it works fine on the simulator, but I cant seem to build it for the devices. Here is my error log:

I really need this working ASAP, for a commercial project, please. BASS looks impressive and solved in hours what days of OGG ramblings couldn't help.
Have you guys used stuff only available in CoreServices?

[Ian @ un4seen]

That looks like it is linking with the wrong library version, eg. the "simulator" BASS when you're building a "device" application. I think the simplest way to avoid that problem is to just add both BASS library versions to the project.

edit: Actually, looking at it again (more closely this time!), that looks like it is linking with the wrong CFNetwork framework version, ie. the OSX version rather than the iPhone version? You could try removing that from the project, and then adding it again, eg. right-click on the project, select "Get Info", click the "+" button below the "Linked Libraries" list, and select "CFNetwork" from the list of frameworks.

[NeoStrider]

Nevermind...it was XCode fault...again...
Got everything working very well here.
Now is time to evaluate the licenses...
Thanks!

[Bert]

Do you want to share your working example with us?

Would be very nice!

[NeoStrider]

Its surprisingly the same as the macosx radio player. The only problem was removing the callbacks and handlers from Carbon Stuff. I still need to write a proper buffer manager, and then I promisse to give back to you something...

[rdalton]

Hi Ian,

The iPhone port is much appreciated.  Nice work!  I was just wondering if you are using the Tremor decoder (fixed-point Ogg decoder)?  If not, are there any plans to incorporate it sometime soon?

Thanks.

[atatum1]

Is there a blackberry version as well please?

[hippocoder]

Does this work with the iPad?

[Bert]

Yes, i think it's working on the ipad.

[hippocoder]

Brilliant!

I want to deploy to windows, mac, iphone and ipad. I do have plans to use android and windows mobile but I think I will just have to recode those bits (bite the bullet) so to speak.

[Ian @ un4seen]

The fixed-point OGG decoder is used in the WinCE version of BASS, but not the iPhone version, as the iPhone does have an FPU. I don't remember the numbers now, but I seem to recall finding that the fixed-point decoder wasn't faster on the iPhone.

Is there a blackberry version as well please?

I'm afraid there aren't any plans for that at the moment, but who knows in the future

Hi everybody,

I tried BASS for my iPhone application. It works very well but I have a problem...
When my iPhone locks screen, there is no more sound. I read Apple documentation, it seems that I should setup Audio sessions and set the AVAudioSessionCategoryPlayback category. But it has no effect.

Has anyone got this issue ?

Thanks a lot !

Thanks a lot !

Try this code:

Code: [Select]

AudioSession.Category = AudioSessionCategory.MediaPlayback

[sui]

I tried two things :

Code: [Select]

[[AVAudioSession sharedInstance] setDelegate: self];
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: nil];
NSError *activationError = nil; [[AVAudioSession sharedInstance] setActive: YES error: &activationError];

and

Code: [Select]

UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty (kAudioSessionProperty_AudioCategory,  sizeof (sessionCategory), &sessionCategory);

It works with AVAudioPlayer but not with BASS...

I tried your code but I can't compile it (is it Obj C code ?).

Thanks a lot !

[sui]

Ok, I just fixed it...

Call

Code: [Select]

BASS_Init(-1,44100,0,NULL,NULL);

BEFORE

Code: [Select]

UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty (kAudioSessionProperty_AudioCategory,  sizeof (sessionCategory), &sessionCategory);

And not after... It's better !

Thanks

[ken]

Good to hear, I don't code in Obj-C, I use Monotouch and code in C#, thats why my call didn't work right of.

[Ian @ un4seen]

BASS_Init sets the "audio session category" itself, so that will be why you are having to apply your settings after the BASS_Init call, rather than before it.

BASS currently uses the kAudioSessionCategory_AmbientSound setting, as that allows the system audio to continue in the background, eg. if the user wants to listen to their music while playing a BASS-based game. But it looks like that is now (since iPhoneOS 3.0) possible with the kAudioSessionCategory_MediaPlayback setting too, so an updated build that uses that setting is now in the iPhone package (see the 1st post).

Ok, thanks Ian, I understood why it did not work.
