previous one, but usually ends up using three of them at the current CACHE_HIGH_WATER setting. Should result in a smaller memory footprint for sessions with multiple copies of nearby audio segments (electronic style). The downside is the larger memory footprint for linear recording sessions if CACHE_HIGH_WATER > 1 (1 giving a max of two half - sized cache entries per audio stream).
