Derry's Top TipsHow to extract drums from a music track

Our CTO Derry explains how you can use DeMIX software to cleanly extract drum samples from any music track, enabling you to create isolated drum tracks

There are many reasons why you might want to extract drums from a music track. You might be a DJ be looking for a drum sample for a remix or a mashup, or you might be a drummer who wants want to be able to get an isolated drum track so you can study or learn a drum part in greater detail, or maybe you want to play drums with your favourite band!

With the advent of modern AI-based separation technology, separating drums can be done at the click of a button. While you won't be able to extract individual drums, you will be able to extract most types of drum and percussion simply and easily. However, there are still some important steps that you should consider before attempting to separate a drum track. In a previous blog post, I outlined that using a lossless audio format as input gives better results than using a lossy audio format such as mp3. The golden rule in separation and extraction is 'Bad input produces even worse output' and generally applies in all cases where you want to separate an instrument or vocals.

If you are looking to extract a drum loop from a song, I'd advise you to process the whole track rather than just a snippet containing the loop you want. There are two reasons for this: firstly it can take a second or two of audio before the separation algorithm starts separating properly, and processing the full song will help ensure that the section you actually want is separated correctly. Secondly, your end result varies depending on the other instrumentation and vocals present at any given point in the track. So with a full track separation, you can see if the drum part is cleaner at different points throughout the song. You can then pick the section that's likely to give you the best-separated sound quality.

A common complaint about AI-based drum separations is that they don't preserve the initial transients or attack of the drum sound. Where possible you want to ensure that these transients are preserved, so that the drums you extract retain more of their natural punch than other separation systems. This can make a significant difference to the end quality of the separation and the reason why we developed custom algorithms for our products designed specifically to ensure that transients are retained for a more natural sound.
