Redrumming or drum replacement is used to substitute or enhance the drum hits in a song with one-shot drum sounds obtained from an external collection or database. In an ideal setting, this is done on multitrack audio, where one or more tracks are dedicated exclusively to drums and percussion. However, most non-professional producers and DJs only have access to mono or stereo downmixes of the music they work with. Motivated by this scenario, as well as previous work on decomposition techniques for audio signals, we propose a step towards enabling full-fledged redrumming with mono downmixes.

Let there be drums
This figure shows an overview of our break-informed redrumming method. The left side contains the track that will be redrummed, separated into a harmonic part (horizontal orange bars) and three percussive parts (for kick, snare, and hi-hat). The right side contains the track that will provide the timbral information for the redrum, with sounds being "copied" onto appropriate timepoints in the left-hand track.

Example: Incredible Bongo Band - Apache [YouTube Link]

For these examples we have fixed "Apache" by the Incredible Bongo Band as the track to be redrummed, using different breaks as timbral sources. All tracks labeled as Redrum mix contain the harmonic information from "Apache", together with the corresponding redrum. All tracks labeled as Redrum percussion contain only the redrum percussion, facilitating comparison.
