// Photon_Audio_In works in 2 modes.
// 1. Fills buffer provided in ..._Read call. Takes minimum cpu cycles in render callback. But requires ring buffer adding some latency
// 2. Pushes audio data via callback as soon as data is available. Minimal latency and ability to use "push" Photon Voice interface which is more efficient.
// Push mode enabled if CallbackData.pushCallback property set.
