| Member name | Value | Description | |
|---|---|---|---|
| BASS_IOS_SESSION_MIX | 1 | Allow other audio to mix with the app's audio (enables kAudioSessionProperty_OverrideCategoryMixWithOthers). | |
| BASS_IOS_SESSION_DUCK | 2 | Also duck the other audio (enables kAudioSessionProperty_OtherMixableAudioShouldDuck). | |
| BASS_IOS_SESSION_AMBIENT | 4 | Use the ambient category (enables kAudioSessionCategory_SoloAmbientSound/AmbientSound instead of kAudioSessionCategory_MediaPlayback). | |
| BASS_IOS_SESSION_SPEAKER | 8 | Route the output to the speaker instead of the receiver. Enables AVAudioSessionCategoryOptionDefaultToSpeaker. | |
| BASS_IOS_SESSION_DISABLE | 16 | BASS's audio session configuration management so that the app can handle that itself. | |
| BASS_IOS_SESSION_DEACTIVATE | 32 | Deactivate the audio session when nothing is playing or recording. It is otherwise only deactivated when there are no initialized devices and during interruptions. | |
| BASS_IOS_SESSION_AIRPLAY | 64 | Allow playback on Airplay devices when recording (Airplay is always allowed when only playing). Enables AVAudioSessionCategoryOptionAllowAirPlay. | |
| BASS_IOS_SESSION_BTHFP | 128 | Allow Bluetooth HFP (hands-free) devices when recording (Bluetooth is always allowed when only playing). Enables AVAudioSessionCategoryOptionAllowBluetooth. | |
| BASS_IOS_SESSION_BTA2DP | 256 | Allow Bluetooth A2DP devices when recording (Bluetooth is always allowed when only playing). Enables AVAudioSessionCategoryOptionAllowBluetoothA2DP. |
By default, the audio session category is set to AVAudioSessionCategoryPlayback. If BASS_IOS_SESSION_AMBIENT is set then the category will be set to AVAudioSessionCategorySoloAmbient instead, or AVAudioSessionCategoryAmbient if BASS_IOS_SESSION_MIX or BASS_IOS_SESSION_DUCK is also set. If BASS_IOS_SESSION_SPEAKER is set or BASS_RecordInit has been called then the category will be set to AVAudioSessionCategoryPlayAndRecord (regardless of BASS_IOS_SESSION_AMBIENT). Descriptions of these categories and other options can be found in Apple's AVAudioSession documentation.
When BASS's audio session configuration management is disabled (BASS_IOS_SESSION_DISABLE is set), BASS will still activate the session during initialization and after an interruption but do nothing else. Except for the "No Sound" device, the BASS_CONFIG_DEV_PERIOD option is disabled by this; the AVAudioSession setPreferredIOBufferDuration method can be used instead.
