1. An audio content item identifier, comprising:
at least one processor; and
at least one memory storing instructions which when executed by the at least one processor cause the at least one processor to:
receive, by a client device, a query corresponding to a query audio content item;
determine a query vector corresponding to the query audio content item;
compare, in a vector space, the query vector and a plurality of target vectors corresponding to a plurality of target audio content items, to determine likelihood values indicating, for each respective target audio content item of the plurality of target audio content items, a probability that the respective target audio content item is a match for the query audio content item, wherein the query audio content item and the target audio content items are audio stems that are configured to be inserted into an audio content item during an audio content item creation process; and
output, to an editor tool, information identifying one of the plurality of target audio content items having a highest of the likelihood values.
