GstAudioClock makes it easy for elements to implement a GstClock, they simply need to provide a function that returns the current clock time.
This object is internally used to implement the clock in GstBaseAudioSink.

GstClockTime (*GstAudioClockGetTimeFunc) (GstClock *clock,gpointer user_data);
This function will be called whenever the current clock time needs to be calculated. If this function returns GST_CLOCK_TIME_NONE, the last reported time will be returned by the clock.

| Returns : | the current time or GST_CLOCK_TIME_NONE if the previous time should be used. | 
GstClock* gst_audio_clock_new (const gchar *name,GstAudioClockGetTimeFunc func,gpointer user_data);
Create a new GstAudioClock instance. Whenever the clock time should be
calculated it will call func with user_data. When func returns
GST_CLOCK_TIME_NONE, the clock will return the last reported time.

GstClockTime gst_audio_clock_adjust (GstClock *clock,GstClockTime time);
Adjust time with the internal offset of the audio clock.

| 
 | a GstClockTime | 
| Returns : | timeadjusted with the internal offset. | 
Since 0.10.23
GstClockTime        gst_audio_clock_get_time            (GstClock *clock);
Report the time as returned by the GstAudioClockGetTimeFunc without applying any offsets.
| 
 | a GstAudioClock | 
| Returns : | the time as reported by the time function of the audio clock | 
Since 0.10.23
void gst_audio_clock_reset (GstAudioClock *clock,GstClockTime time);
Inform clock that future calls to GstAudioClockGetTimeFunc will return values
starting from time. The clock will update an internal offset to make sure that
future calls to internal_time will return an increasing result as required by
the GstClock object.
