Functions

std::unique_ptr< T, FreeDeleter< T > >

makeAlignedArray (size_t size, size_t alignment=16)

Returns an array of size elements of type T , aligned by alignment .
CI_API const ChannelRouterNodeRef &
operator>> (const NodeRef &input, const ChannelRouterNode::RouteConnector &route)
Enable routing connection syntax:
```
input >> output->route( inputChannelIndex, outputChannelIndex, numChannels ); 
```
.

the output ChannelRouterNode after connection is made.
Context *

master ()

Returns the master Context that manages hardware I/O and real-time processing, which is platform specific. If none is available, returns null .
const NodeRef &

operator>> (const NodeRef &input, const NodeRef &output)

Enable connection syntax: input >> output , which is equivelant to input->connect( output ) . Enables chaining.

timeToFrame (double timeSeconds, double sampleRate)

Convert timeSeconds to frames running at sampleRate , rounding to the nearest integral frame.
CI_API bool

thresholdBuffer (const Buffer &buffer, float threshold, size_t *recordFrame=nullptr)

Checks if the absolute value of any sample in buffer is over threshold . Optionally provide recordFrame to record the frame index.

true if one is found, false otherwise.
