Top 5 Human Whistle Plugins & Sample Libraries 2023

Top 5 Human Whistle Plugins & Sample Libraries 2023

Let’s dive into the best options for human whistle VST plugins available in 2023.

Humans are very musical beings, and we’ve been like that for quite a long time. We always like to express our thoughts and feelings through music, independent of how it’s formed. You can beat up a drum, blow a flute, or even sing a melody with your voice.

Another fantastic way to make music is by whistling. It’s a creative and musical way to manipulate the airflow from your lungs, just like singing. Unfortunately, however, many people don’t know how to whistle – it’s understandable, as this technique depends primarily on one’s lips and overall mouth shape. 

To remedy that, we have a collection of five great human whistle virtual instrument plugins that are still relevant in 2023. These are friendly software that allows for optimal customization and provides great sonority in the final result, thus making it irrelevant if you know how to make complex melodies with your lips.

Let’s look into the options.

Top 5 Human Whistle VST Plugins  / Kontakt Libraries 2023

1. Lennar Digital Sylenth1 (Make Your Whistle)

More Info & Price 
This powerful synthesizer can recreate whistles very quickly.

It’s common to see multiple synth virtual instrument plugins nowadays, with the most diverse sonorities and uses. So we can opt for a perfect replica of an authentic vintage unit and simultaneously use a new and strange variation that sounds wonderful. The goal behind Lennar Digital Sylenth1 is to have a bit of both, providing the best tools any producer could want.

Top 5 Human Whistle Plugins & Sample Libraries 2023

Key Features:

    • Oscillators
      Lennar Digital Sylenth1
      has four main oscillators that are alias-free and capable of generating analog waveforms. Each oscillator can produce up to eight unison voices in stereo, thus adding up to 32 voices per note. Adding the 16 notes of polyphony means you can reach up to 512 voices played simultaneously, which is enormous.
    • Filters
      There are two filter sections in Lennar Digital Sylenth1, each containing four filter stages with non-linear saturation. This recreates the warmth and analog bliss that the vintage units are often hailed for. In addition, the “Resonance” control can be significantly increased in volume and combined with the “Drive” control for an authentic, energetic performance.
    • Light performance
      Although Lennar Digital Sylenth1 is complex software with multiple features, it’s surprising that it doesn’t consume much CPU data. The highly optimized algorithm and the SSE instructions reduce CPU power consumption to a minimum, automatically turning off segments of the synthesizer that are not being used to save extra power for what you’re doing now.
    • Modulation
      You can count on two envelope sections capable of dealing with the basic ASDR controls, aside from two LFOs which can be used to modulate any set of parameters you choose. With the different amplitude envelopes, velocity markers, and the modulation wheel, you can easily tweak the signal to become more like a whistle.
    • Effects
      The master FX section houses the effects that can be used to make your sound go wild. You can expect to find a step-sequencer arpeggiator, phaser, distortion, EQ, chorus, delay, flanger, compressor, and the classic reverb to add the proper ambiance to everything.


This plugin is available for macOS 10.9 or higher (64-bit only) and Windows 7 or higher (64-bit only). It runs in VSTi, AAX, and AU plugin formats.


If you’re looking for a way to make complex whistle sounds (and more) in an in-depth manner, then Lennar Digital Sylenth1 can be a good option. The number of controls might seem crazy to someone wishing to recreate something quickly, but if you’re used to working with synths, this can be friendly. Of course, better options are available, but this indeed delivers what it promises.

2. Embertone Whistler Ensemble

More Info & Price 
A dedicated library for generating good-sounding whistles.

Embertone has appeared previously in our articles with excellent libraries that can be specific and otherwise. When we say thorough, we mean it! An excellent example is today’s pick, called Whistler Ensemble. So be ready to get the perfect whistle samples for your productions in a simple and elegant interface display.

Whistler Ensemble - Walkthrough

Key Features:

    • Legato
      are very dependent on articulations, such as legato, as they are generated via airflow. To get this nailed perfectly, Whistler Ensemble counts on a “normal” legato with a very smooth slur and an “emo” legato, which can be more emphasized.
    • Air control
      To make your whistle more authentic, you can set the perfect amount of air, making it louder/stronger or quieter/weaker. If you turn it down to zero, the instrument sounds like a creepy sine wave, thus expanding your sonorities even further.
    • Whistlers
      Whistler Ensemble
      is a professional tool; as such, it was recorded in the best way possible by Embertone. To ensure all your needs are attended to, this library was recorded with five simultaneous professional whistles that can ring very clearly when singing together in unison.
    • Performance
      You can control your whistles usually via your MIDI keyboard; for that, you can fully use the velocity control and the MIDI CC values that can be attached to any keys you’d like. In addition, you can further set your playability via a dedicated MPE Control.
    • Reverb
      If you need to add just a pinch of reverb, the dedicated “Reverb” knob will attend to you wonderfully. This is essential to vocal ensembles because it sets the appropriate resonance and ambiance, generating a more vivid and authentic sonority for your whistle group.


This library is available for macOS 10.4 or higher (64-bit only) and Windows XP or higher (64-bit only). It runs only in Kontakt version 4.2.4 or higher, in standalone mode, and comes in VST and AU plugin formats.


Unlike other Embertone products, Whistler Ensemble is dedicated to a single and exclusive use. The recording process was masterful and provided excellent samples to work with, which translates into a more humanized and organic sonority. It’s nice to have up to five players whistling simultaneously in your song; creating melodies with it can be fun.

3. Rast Sound Whistle 2

      added some advantageous effects to Whistle 2, which includes a transient shaper, delay, phaser, reverb, and “Color,” a specific filter to tame your frequencies better. The reverb has “Hall,” “Giant,” “Drums,” and “Noise” room types.
