Detailed Description

Input stream for reading audio from the computer's microphone.

Constructor & Destructor Documentation

AudioStream::AudioStream ( uint32_t downsample_rate = 1 )

int AudioStream::getNumInputDimensions ( )

finalvirtual

Get the number of dimensions of the data that's provided by the input stream (before it's run through the normalizer, if any).

Implements InputStream.

bool AudioStream::start ( )

finalvirtual

Start the stream.

Reimplemented from Stream.

void AudioStream::stop ( )

finalvirtual

Reimplemented from Stream.
