Function aic_processor_process_planar 

pub unsafe extern "C" fn aic_processor_process_planar(
    processor: *mut AicProcessor,
    audio: *const *mut f32,
    num_channels: u16,
    num_frames: usize,
) -> Type

Processes audio with separate buffers for each channel (planar layout).

Enhances speech in the provided audio buffers in-place.

Memory Layout:

• audio is an array of pointers, one pointer per channel
• Each pointer points to a separate buffer containing num_frames samples for that channel
• Example for 2 channels, 4 frames: audio[0] -> [ch0_f0, ch0_f1, ch0_f2, ch0_f3] audio[1] -> [ch1_f0, ch1_f1, ch1_f2, ch1_f3]

The planar function allows a maximum of 16 channels.

Parameters

• processor: Initialized processor instance. Must not be NULL.
• audio: Array of num_channels pointers, each pointing to a buffer of num_frames floats. Must not be NULL.
• num_channels: Number of channels (must match initialization).
• num_frames: Number of samples per channel (must match initialization value, or if allow_variable_frames was enabled, must be ≤ initialization value).

Note

All channels are mixed to mono for processing. To process channels independently, create separate processor instances.

Returns

• AIC_ERROR_CODE_SUCCESS: Audio processed successfully
• AIC_ERROR_CODE_NULL_POINTER: processor or audio is NULL
• AIC_ERROR_CODE_NOT_INITIALIZED: Processor has not been initialized
• AIC_ERROR_CODE_AUDIO_CONFIG_MISMATCH: Channel or frame count mismatch
• AIC_ERROR_CODE_ENHANCEMENT_NOT_ALLOWED: SDK key was not authorized or process failed to report usage. Check if you have internet connection.

Safety

• Real-time safe: Can be called from audio processing threads.
• This function is not thread-safe. Do not call this function from multiple threads.
