A base class for simple audio filters.
Gst::AudioFilter is a Gst::BaseTransform-derived base class for simple audio filters, ie. those that output the same format that they get as input.
Gst::AudioFilter will parse the input format for you (with error checking) before calling your setup function. Also, elements deriving from Gst::AudioFilter may use gst_audio_filter_class_add_pad_templates() from their base_init function to easily configure the set of caps/formats that the element is able to handle.
Derived classes should override the Gst::AudioFilter::setup_vfunc() and Gst::BaseTransform::transform_ip_vfunc() and/or Gst::BaseTransform::transform_vfunc() virtual functions.
