Struct InputAudioBuffers 

pub struct InputAudioBuffers<'a> { /* private fields */ }

Implementations

impl<'a> InputAudioBuffers<'a>

pub const fn empty() -> Self

pub fn truncate(&mut self, max_buffer_size: u32)

Shortens the frames_count of these input buffers.

This does not actually change the underlying buffers themselves, it only reduces the slice that will be exposed to the plugin.

This method does nothing if max_buffer_size is greater or equal than the current frames_count.

pub unsafe fn from_raw_buffers( buffers: &'a [clap_audio_buffer], frames_count: u32, ) -> Self

Safety

The caller must ensure all buffer structs are valid for ’a, including all the buffer pointers they contain.

The caller must also ensure frames_count is lower than or equal to the sizes of the channel buffers pointed to by buffers.

pub fn from_plugin_audio(audio: &Audio<'a>) -> InputAudioBuffers<'a>

Available on crate feature clack-plugin only.

pub fn as_plugin_audio(&self) -> Audio<'a>

Available on crate feature clack-plugin only.

pub fn as_raw_buffers(&self) -> &'a [clap_audio_buffer]

pub fn port_count(&self) -> u32

The number of port buffers this InputAudioBuffers has been given.

pub fn frames_count(&self) -> Option<u32>

The number of frames in these input buffers.

This is the minimum frame count of all the port buffers this has been given.

If this has no port buffer (i.e. port_count is zero), this returns None.

pub fn port_info(&self, port_index: u32) -> Option<AudioPortProcessingInfo>

pub fn port_infos(&self) -> impl Iterator<Item = AudioPortProcessingInfo> + '_

pub fn min_available_frames_with(&self, outputs: &OutputAudioBuffers<'_>) -> u32

Returns the minimum number of frames available both in this InputAudioBuffers and the given OutputAudioBuffers.

This is useful to ensure a safe frame count for a process batch that would receive those input and output audio buffers.
