 ### Expiring stale codes
 
-Finally, the SoundStream paper has a scheme where they replace codes that have not been used in a certain number of consecutive batches with a randomly selected vector from the current batch. You can set this threshold for consecutive misses before replacement with `max_codebook_misses_before_expiry` keyword. (I know it is a bit long, but I couldn't think of a better name)
+Finally, the SoundStream paper has a scheme where they replace codes that have hits below a certain threshold with randomly selected vector from the current batch. You can set this threshold with `threshold_ema_dead_code` keyword.
