Comment (by richardpl):

 From logs its obvious that something caches huge amounts of memory,
 probably because of messing with PTS (presentation timestamps) in your
 graph.

 Please consider using agraphmonitor with only audio filters, if it shows
 big cache numbers than it is bug in some of filters, otherwise it is badly
 designed filtergraph.

 Also I see some frames have NAN timestamps, this will obviously cause big
 caching issues.

 Also please consider uploading short input samples which would allow to
 reproduce this memory issue.
