# qtimlaconverter

Source: [https://docs.qualcomm.com/doc/80-70020-50/topic/qtimlaconverter.html](https://docs.qualcomm.com/doc/80-70020-50/topic/qtimlaconverter.html)

The qtimlaconverter plugin processes the incoming audio waveform data into ML
        tensors. The ML models such as the audio classification model process these tensors for
        inferencing.

[GstCaps](https://gstreamer.freedesktop.org/documentation/gstreamer/gstcaps.html) determines the transformation on the
            plugin output. GstMLBufferPool, a custom buffer pool class, can do the following:

- Assign the output buffers.
- Assign the ION buffers through IOCTL commands to the kernel.

## Inheritance chain

[GObject](https://docs.gtk.org/gobject/) → [GstObject](https://gstreamer.freedesktop.org/documentation/gstreamer/gstobject.html?gi-language=c) → [GstElement](https://gstreamer.freedesktop.org/documentation/gstreamer/gstelement.html?gi-language=c) → [GstBaseTransform](https://gstreamer.freedesktop.org/documentation/base/gstbasetransform.html?gi-language=c) → GstMLAudioConverter
