Release an audio context
-------------------------

Once the end of the file or stream being processed is reached, the context should not be reused.
If more processing is required (eg another file or stream) then a new context should be created.

Releasing a context that is no longer required frees up any initialised memory used by that context.

.. tabs::

  .. code-tab:: c++

    // Release an audio processing context
    Iris::releaseAudioContext(config.contextId);

    // any call to process with this contextId will now return silence.

  .. code-tab:: py

    # Release an audio processing context
    iris.sdk.release_audio_context(config.context_id)

    # any call to process with this context_id will now return silence.

  .. code-tab:: typescript

    // Release an audio processing context
    iris.releaseAudioContext(config.contextId)

    // any call to process with this context_id will now return silence.


Once all processing is complete, all memory used by the sdk should be freed by calling :func:`~.cleanup`.


.. tabs::

  .. code-tab:: c++

    // Release all unreleased audio processing contexts, free all sdk memory
    Iris::cleanup();

    // Iris::init() must be called again before any further usage

  .. code-tab:: py

    # Release all unreleased audio processing contexts, free all sdk memory
    iris.sdk.cleanup()

    # iris.sdk.init() must be called again before any further usage

  .. code-tab:: typescript

    // Release all unreleased audio processing contexts, free all sdk memory
    iris.cleanup()

    // iris.sdk.init() must be called again before any further usage
