drumatom Player is covered by the following patents: https://accusonus.com/patents


Drumatom is a novel drum processing tool that offers a fresh perspective on leakage suppression. At its heart lies an advanced patent-pending algorithm that will scan your drum tracks, detect bleed and help you dial in as little (or as much) as you want.
The user has two separate software tools at his/her disposal: drumatom (the standalone application) and drumatom player (the plugin). The standalone application is the functional core, performing all necessary analysis of audio information and file handling. The plugin can open sessions saved by the standalone application, allowing for easy DAW integration. It should be noted that the plugin will not analyze drum tracks (it's currently simply impossible in real-time) and will load already analyzed groups instead. In short, using the standalone application is necessary to make any meaningful use of the plugin.


Drumatom player expands on the standalone application's functionality, by allowing you to tweak the suppression controls in the context of a mix. The most important thing to remember is that drumatom player works as a companion to the drumatom application. Use the latter to load and analyze your recorded drums. For more information on using the standalone application, please refer to the drumatom application Manual.
After saving the session as a .dls file, you're ready to open your DAW of choice and start using the plugin.

System Requirements

Minimum OS specs are as follows:
  • Windows: 7, 8, 10
  • OSX: v10.9 and upwards
4GBs of RAM are the absolute minimum for operation. 8GBs or more are highly recommended.

Supported Plugin Formats

Drumatom player supports AAX (32, 64 bit), VST (64-bit), AU (32, 64 bit) and RTAS . You will find it in the ``instruments'' category.

Supported Sample Rates

  • Bitrates: 16,24,32 bits
  • Sampling rates: 44.1, 48, 88.2, 96, 192 kHz

ATTENTION Please keep in mind that drumatom player WILL NOT resample your files to match the DAW project's sample rate. You should perform any over- or downsampling in an external editor before using it.


Drumatom player is quite straightforward to setup and activate. Please refer to the included activation manual for detailed information.


Here are the basic steps to get started with the plugin. It is assumed that the user is already familiar with the standalone application and has a saved Drumatom session in his hard disk (for more info, please check out the Application Quickstart guide).

Drumatom Player UI and Controls

The drumatom player UI consists of four areas:
  • The track list.
  • The top bar displaying a waveform of the current processed audio file.
  • The main control section.
Drumatom Player works by loading saved sessions (.dls files) from the standalone application and allowing you to control the amount of leakage present within the context of a full mix. The loaded tracks are played back in sync with the DAW playback head.
Let's see all the GUI elements one by one. We'll start with the track list, since it's the first area you'll be using when setting up a project.

Track List

When opening drumatom player for the first time in a new project, you'll be greeted with an empty user interface (Figure 1).
Your first step is to load up a multitrack session. Press the LOAD GROUP button and select your preferred .dls session.

Figure 5: Drumatom player
Once the group is loaded, the next step is to assign each track to its output. Please note that drumatom player is multi-output by default and supports a maximum number of 16 outputs. The output selector is a drop down menu on the track bar, replacing the standalone application's drum type selector. You might need to set up the multiple outputs in your DAW's mixer first. Please refer to your chosen sequencer's manual on how to do that.

Each track also has a dedicated solo button, to assist you in monitoring. Please note that the solo function is applied on a per-track basis and NOT per-output (i.e. soloing a track that is routed through output 2, will not solo the output).
Drumatom player supports loading of a single group at a time, containing up to 16 tracks. If you choose to load many tracks, keep an eye on that CPU/disk meter!

Figure 6: Choosing track output

WARNING For simplicity's sake, drumatom player does not share the standalone application's functionality in handling tracks. Make sure you have copied, renamed, removed or duplicated any tracks prior to loading the session on the plugin.

Waveform Display

Drumatom player features a waveform display. Since all transport controls are left to the DAW, you cannot select portions, loop or move the cursor. You can however visualize the current position of the playback head, allowing for convenient mixing.

Figure 7: Waveform display

Main Section

Much like the standalone application, the main section is the heart of operations. In fact, the plugin's controls are virtually identical to the application's, helping you feel right at home.


The FOCUS knob is the single most important control in both drumatom and drumatom player. When the FOCUS knob is at its minimum value, no processing is taking place. By turning it clockwise, you can reduce the selected track's leakage and let the original sound shine through. By turning it fully clockwise, you get the maximum possible leakage suppression.

Figure 8: The main controls

Fine Tune

The FINE TUNE knob works alongside FOCUS, giving you the freedom to do detailed adjustments. FINE TUNE works in a reverse fashion. By turning it clockwise, some of the dry signal is added back (to be more precise, the signal added is the difference between the original and the current FOCUS output ). In essence, it's something akin to a Dry/Wet implementation. You may ask: why not just push back FOCUS a little bit? Well, you won't get the same result. FINE TUNE has a finer range of values. The two controls are designed to interact with each other and produce an effect greater than the sum of its parts.

TIP Hold down Cmd/Ctrl to do finer adjustments. Double click on a knob to manually type a value.


Use this button to do quick comparisons between the original and the processed audio signal.


The LINK modifier will help you edit multiple controls with a single mouse sweep. When LINK is active, each track's controls are linked to the corresponding controls of all other tracks. In other words, applying FOCUS on a track while LINK is on, will apply the same amount of FOCUS on all other tracks. This can be handy when you want to make quick global adjustments. The linked controls are highlighted blue: FOCUS, FINE TUNE, BYPASS and output gain.

Figure 9: Link function activated

A/B Switch

You can compare different FOCUS and FINE TUNE settings, by using the A/B switch. Please note that the switch position is saved along with the session.

Suppression Meter

The suppression meter is an extremely helpful tool that lets you visualize the extent to which processing happens. Think of it as the equivalent to a compressor's GR meter. It's designed to mimic traditional LED metering tools and give you a precise indication of how many dBs of suppression are applied.

Track Volume

The TRACK VOLUME slider can help in attenuating (or amplifying) the signal before it hits the DAW's mixer.


Let's take a minute to summarize this section, provide a more in-depth look into the workflow and discuss the results you should expect when using drumatom.When processing your drum channels, the FOCUS knob is your starting point. By turning it fully clockwise, you'll achieve the maximum possible suppression. Depending on the situation at hand and the nature of the recorded files, the MAX setting will usually completely remove leakage. In some cases (especially if the leakage is too prominent), resorting to extreme settings might also make your drums sound unnatural. This is currently unavoidable. When your drum recording contains excessive amounts of leakage, or when your recorded track contains a very small number of drum hits (as typically happens for example in the case of toms), it's practically impossible to perfectly identify the main sound. If you want to make an analogy, think about a de-noise tool: the performance of the tool depends on the type and level of noise.
The best way to use FOCUS is to start from the MIN setting. Slowly and carefully work from there. A lot of times, a few dB of suppression will work wonders. Toggle BYPASS to do a comparison between the original and the processed version. Keep an eye on the suppression meter and the waveform view to get a picture of what's happening.
If you're not completely satisfied with what you hear, you might find that finer adjustments are needed. That's what the FINE TUNE knob is there for. Start turning that knob clockwise and listen: some of that bleed will come back, albeit in a delicate and discreet fashion. Experimenting with different settings of FOCUS and FINE TUNE is the heart of Drumatom's operation. These two controls are designed to work in tandem. Take your time to explore the interactions and listen to the effect. You'll soon feel quite familiar!


The available automation parameters per track are:
The plugin supports a maximum number of 16 tracks per group, giving a total of up to 64 automatable parameters for A and B states.

For details on how to enable automation, please refer to your DAW's manual.


The drumatom plugin is quite straightforward to use. That said, here are some things to keep in mind.

Dealing with performance issues Drumatom player is extremely light on CPU, since all processor-intensive tasks take place in the standalone application. However, it IS demanding in terms of hard disk data streaming. A fast disk will help you get the most out of it and avoid playback issues.

  • NOTE: Drumatom player demands fast data streaming from the hard disk. Some DAWs do not have the capability to compensate for this, during offline export/mixdown/bounce. So if you experience any strange behaviour, please prefer the real-time export mode.

Take advantage of the multi-out configuration In most mixing cases, multi-out is the way to go when using drum tools. Drumatom player has an output configuration menu right on the GUI and not tucked away in any kind of cryptic ``advanced'' options tab! Make sure to use it.

Prepare your session before using drumatom player Make sure to do any file-related operations before using the plugin. Be smart: delete any tracks you won't use to shorten dls size (overhead mics, room mics and any tracks labelled ``other'' would probably fall into that category). Have you analyzed various combinations of the same group? You might want to gather the preferred results into a single dls file. You can do that in the standalone application, either by dragging and dropping tracks between groups, or with the help of a new, very useful feature: as of v2.0, drumatom has an option to import a track from a saved group (Import > Import Track(s) from DLS).

Synchronization and timing Keep in mind that drumatom players output is slaved to the DAW playback head. As such, selecting audio portions in the waveform view, or looping is not possible via drumatom player. You'll have to use the DAW for that. The plugin's waveform view is meant to be a visual guideline.

Resampling Keep in mind that drumatom player WILL NOT automatically resample your tracks to match the project's sample rate. You should perform all necessary resampling tasks before opening the group.

Find the sweet spot The FOCUS and FINE TUNE knobs need slow, careful handling. The sweet spot will vary from track to track. Just turning FOCUS clockwise will usually not be enough to get the sound you want, so remember to use FINE TUNE as well. Keep in mind also, that FINE TUNE behaves in relation to the current position of FOCUS.

Use the FINE TUNE control The FINE TUNE control is very important. What does it do? It adds back the difference between the processed and the original signal . Think of it as a dry/wet control, specifically tailored to the intricacies of drumatom. Apart from helping you shape your sound in detail, FINE TUNE means that you don't have to set up a dry/wet signal chain in your DAW.

Combining drumatom with other tools It is highly recommended that your drum tracks are not processed before analyzing with the drumatom standalone application. After importing the analyzed session in the plugin, you can start building your mixing chain. Any type of time-domain tool will benefit greatly after a track has been processed by drumatom. Dynamic tools such as gates and compressors will respond more naturally, while spatial effects like reverb, will sit better in the mix.



What are the benefits of using drumatom player? The most obvious and important one: you'll be able to control the amount of leakage reduction in real-time within your DAW. You can also automate the controls to better suit the dynamics of the audio material.

Is drumatom player phase-accurate? Yes. Drumatom player will not introduce any phase inconsistencies.

Can I mix the drumatom player outputs with my original drum recordings? Since the plugin is phase-accurate, yes. It's not necessary though. The FINE TUNE control will produce a similar result and you'll avoid unnecessary clutter in your workspace.

How many instances of drumatom player can I open? There is no theoretical limit in drumatom player instances. Be careful though! Each plugin streams the tracks as well as the analysis data from the session file. If you encounter clicks, pops or dropouts, there's a good chance your hard disk is reaching the limits of its transfer rate.
