virtual void AudioCallbackPlayTarget::sourceModelReplaced

(

)

[pure virtual, slot]

The main source model (providing the playback sample rate) has been changed.

The target should query the source's sample rate, set its output sample rate accordingly, and call back on the source's setTargetSampleRate to indicate what sample rate it succeeded in setting at the output. If this differs from the model rate, the source will resample.

Implemented in AudioJACKTarget, and AudioPortAudioTarget.
