DeviceChannels()

int AudioRecorderInputMapper::DeviceChannels ( int  requested_channels )

static

Number of device channels to open for a requested channel count. Stereo devices are opened as stereo (even for mono recordings), since some drivers convert badly when asked for fewer channels than the device has. Devices with fewer channels are clamped by the audio backend.

FillBlock()

void AudioRecorderInputMapper::FillBlock ( AudioRecorderBlock &  block, int  channels, const float *const *  input_channel_data, int  num_input_channels, int  num_samples  )

static

Copy device input into a block with the requested channel count. Extra channels repeat the first input channel (i.e. a mono device recorded as stereo).
