Thank you for choosing accusonus Beatformer. In order to better understand the main concepts and operation of Beatformer, please take the time to read this user manual.
You can also check out the FAQ or blog section of our site for educational content and follow us on Facebook and YouTube for tips & tutorials.


Beatformer is an audio effect plug-in that focuses on quickly adjusting four basic characteristics of a beat sound:

  • Transients. Quickly adjust the behavior of the transients of the input signal.
  • Harmonics. Enhance the timbre of the sound with the dynamic creation of extra harmonics.
  • Dynamics. Control the dynamic feel of the beat with a single knob.
  • Low End. Smoothly boost the low end of the signal without the use of EQing.

Installation & Activation

You can find the latest Beatformer installer in your accusonus "My Account" page, in the “Downloads” section ( ). For more information about installation and activation see the Activation Manual, which you can find along with the installer.

System requirements

Your computer must have:

  • a modern architecture CPU.
  • a minimum of 2GB RAM memory.
  • at least 50MB free space on your hard disk.
  • a minimum screen resolution of 800x600 pixels.

Supported formats

Beatformer is available as a mono or stereo audio effect plug-in in the following formats:


  • AU (64-bit)

Warning: Beatformer is designed to be used as an audio effect plug-in inside Digital Audio Workstations or Non-Linear Editing systems. Only the plug-in formats listed above are supported.

Supported sample rates

Beatformer supports the following sample rates: 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz.

Supported plug-in hosts

Beatformer is fully tested in the following DAWs and NLEs:

  • Apple Logic Pro 10.4
  • Ableton Live 10
  • ImageLine FLStudio 12
  • Propellerheads Reason 10
  • Presonus StudioOne 3.2

Warning: There are just too many combinations of DAWs and plug-in formats out there, so there's always something we might have not tested. If you don't see your DAW above, you can always download the free, fully-functional 14-day trial and see if Beatformer is supported for yourself. If you encounter any problems, let us know at .

Beatformer Operation

Behind the simple and intuitive user interface of Beatformer is a complex signal flow which is described in the diagram. In the following sections we will discuss each of Beatform control in more detail.

Figure 2: Beatformer Signal Flow Diagram


Figure 3: Air Knob
You can use “Air” to excite the high end or tame excessive high frequencies. Air is a bipolar control. From 0.0 to 10.0 “Air” will dynamically add harmonics to the high frequencies of the signal. On the other hand from 0.0 to -10.0 “Air” will dampen the sound. Behind the scenes “Air” includes a transient shaper and a soft saturation unit, with different settings for M/S (mid/side) or L/R (stereo) processing, and creates an exciter-like effect for values greater than 0.0 and a subtle high-frequency suppressor for values less than 0.0.


Figure 4: Punch Knob
“Punch” affects the transient of the input signal. Punch is a bipolar control. For values between 0.0 and 1.0 the attack of the signal is enhanced while for values between 0.0 and -10.0 the attack is reduced. The dynamics processing behind the scenes, using a transient shaping paradigm, adjusts the attack and sustain parts of the signal to add more “punch” (for positive values) or “flatten” the attacks (for negative values). “Punch” will affect lower frequencies than the ones “Air” controls, giving more emphasis to the mid-frequency range of the signal and sounds like snares, percussion etc.

Figure 6: Squash Knob
“Squash” affects the dynamic range of the signal. It is a bipolar control. For values between 0.0 and 10.0 the signal is “squashed” by bringing the lower-in-gain parts of the signal closer to its peaks. For values between 0.0 and -10.0 this control will create more space between them. “Squash” operates after the “Punch”, on the same frequencies, to control the dynamics, after the transients have been processed with “Punch” and will follow the same Mid-Side or Left-Right processing.

High Split

Figure 8: High-Split Knob
The High Split control allows you to select the crossover frequency beween “Air” and “Punch”/”Squash”. You can select values between 4kHz and 12kHz. This control enables you to find the sweet spot in the frequency spectrum that will separate instruments of interest, like for example the hi-hats from the snare, the tambourine from the congas etc.


Figure 9: Boom Knob
Boom smoothly enhances the low frequencies of the signal by dynamically adding extra harmonics to the low end. The drop-down menu under the control can be used to blend the created harmonics with an event-driven tone generation. The key specified will change the pitch of the effect for tuning the low-end sounds like the kick-drum, toms etc as preferred.

Input-Output Gains

Figure 10: Input-Output Gain Knobs
You can adjust the Input Gain between -24dB and +24dB and the Output Gain between -12dB, and +12dB. The Input Gain adjusts the gain of the signal before hitting the dynamic processors found in Air, Punch, Squash and Boom. This means that the behavior of these processors may change if the signal is being pushed with large input gain levels. The Output Gain, on the other hand, is applied after all processing but before the limiter.


Figure 11: Limiter Switch
You can use the “Limit” switch to enable or disable the limit at the end of the signal flow before the plug-in output. This limiter has an automatic release time and is set at a 0dB threshold. It helps control excessive peaks that may result with extreme settings of the four main controls. It is a transparent limiter that only acts as a safety net. You can use the Output Gain to drive the processed signal to the limiter input.The Output Gain is being placed after these processors and before the Limiter to give a control over the preferred pushing of the gain to the altered signal inside the Limiter.


When the ”Bypass” button is active, all processing is bypassed and the original signal comes through Beatformer untouched.

Tip: It is usually better to use and automate this button to bypass processing, since this will keep the audio in sync (retain the declared latency to your DAW) with the rest of the DAW tracks.

Preset Menu

Beatformer comes with a set of Presets that can help you quickly find a suitable characteristic sound to your beat or catch a glimpse of how the plugin tranforms the sound. You can load any of the factory Presets or create your own and store them in Beatformer.

Resizing the plug-in window

Beatformer offers the option to resize the plug-in window. This can be especially helpful if you have large or high-resolution screens or you just want to focus on a specific task. Click the zoom icon at the top right corner and choose between three settings.
