SPSoundChannel.pan gone?

Biochili

Hi,

In some older version of Sparrow there used to be the "pan" property in SPSoundChannel. In 2.1 (or some other version) this property has disappeared.
I tried to find release notes that might explain the removal, no luck yet (CHANGELOG.md did not help).

In my app I want to play mono sounds at a location in the stereo panorama. Any idea how I can accomplish that in 2.1?
I consider panning to be very useful in my app because it will also be released for tvOS. Too bad it was removed...

I see that there are subclasses SPAVSoundChannel and SPALSoundChannel, but there is no pan parameter either.

Thanks for any help!

I believe there have been extensions that have included this, but 2.1 didn't have a 'pan' property. Maybe it was in a 1.x version? I'll look into including it though.

Hi, thanks for your reply. Indeed the pan property was there in some older 1.x version.

Edit:
I just noticed SPALSound.bufferId is there so I could create my own category. 🙂

Edit: I just found out that OpenAL does not position sounds with >1 channels. D'oh! My app uses stereo sounds so actually I cannot even use panning. 😠

In SPALSoundChannel.m, you need to add:

- (void)setPan:(float)right {
    float pos[] = { right, 0.0f, 0.0f };
    alSourcefv(_sourceID, AL_POSITION, pos);
}
