Bundle that includes Voxengo pro audio plugins designed for mastering applications. ย These plugins allow you to achieve clear, loud and balanced-sounding mixes.
Voxengo CurveEQ

...your mastering equalizer as it is meant to be
CurveEQ is a spline equalizer for professional music and audio production applications. ย CurveEQ shows you the actual filter response you are designing by means of a spline (a smooth curvy line), so you can actually see what the EQ is doing with the sound. ย This, in turn, allows you to get the best from your mix and your tracks. ย CurveEQ perfectly suits the needs of mastering.
CurveEQ implements spectrum matching technology that allows you to transfer spectrumโs shape of one recording to another. ย In other words, this allows you to โcopyโ frequency balance of existing time-proven mixes so that other mixes that are still in the works may have a chance to sound better. ย This technology also greatly helps in music mastering since it easily lessens any dramatic differences in the area of frequency balance between various tracks.
CurveEQโs filters can be switched between linear- and minimum-phase modes. ย CurveEQ also features a deeply-customizable spectrum analyzer like the one found in Voxengo GlissEQ and SPAN plug-ins. ย You may also display, save and load static spectrum plots for comparison and matching purposes.

Voxengo Elephant

...makes your mixes loud and proud adding a brilliant finishing touch
Voxengo Elephant is a mastering limiter AU and VST plugin for professional music production applications. ย The most remarkable feature of this signal limiter is its sonic transparency. ย Elephant brings sound limiting and loudness maximization without audible โpumpingโ sonic artifacts.
Elephant is a highly competitive plug-in for mastering applications: it features a variety of limiter modes that can be deeply customized, and a comprehensive set of level metering tools, including headroom estimation and K-system metering. ย Elephant's built-in linear-phase oversampling is an important element in achieving high-quality peak limiting and loudness maximization.
Elephant limiter can be used for mixing and mastering of both stereo and multi-channel music and sound material, at any standard sample rate. ย Limiting process can be visualized both as gain reduction meter and real-time graph.
Elephant, also featuring a DC offset filter, and a high-quality bit-depth converter with an optional noise-shaping, allows you to finish your music and audio productions with a spark.

Voxengo Polysquasher

...glue your mix together so that nobody tells something does not "sit" well
Voxengo Polysquasher is a mastering compressor AU and VST plugin for professional audio and sound production applications. ย Polysquasher was designed with a main goal: to be transparent. ย Transparent compression action is a cornerstone for any mastering compressor. ย Transparency of audio signal processing is necessary to preserve all existing elements in the mix, while compression itself is necessary to make the mix sound uniform to other mixes (tracks) and to make it sound more solid and โgluedโ.
Polysquasher achieves its goal by using a unique compression algorithm which requires a small number of parameters โ basically threshold and ratio only โ making this compressor a joy to use. ย More advanced settings are hidden in the โcompressor mode editorโ panel where you can create your own compressor modes that can be easily recalled later.
Polysquasher is best used as a finishing compressor inserted in the chain before the final mastering limiter.
Polysquasher also features real-time gain reduction and waveform graphs. ย Full multi-channel operation is supported.
Applications
- Mastering compressor
- Stereo, mid-side, 5.1 compressor
- Clean-sounding compressor
Features
- Transparent compression sound
- Compressor mode editor
- Channel grouping
- 64-bit floating point processing
- A/B comparisons

- Mid/side processing
- Preset manager
- Contextual hint messages
- 8 built-in compressor modes
- Internal channel routing

Voxengo Soniformer
![]()

...master your tracks with confidence
Soniformer is a spectral mastering dynamics processor plug-in for professional music production applications. ย During its operation, Soniformer splits incoming sound signal into 32 spectral bands. ย This makes Soniformer a powerful and precise tool for mastering and sound restoration purposes.
Every parameter in Soniformer is defined by means of a graphic envelope which is freely-modifiable and which may contain unlimited number of control points. ย Beside usual threshold, attack, release and compression/expander ratio parameters Soniformer offers you control over โstereo widthโ and โpanningโ parameters making Soniformer an effective tool for stereo field adjustments.
Not only Soniformer offers you an easy-to-use parameter envelope editing interface, it also features a comprehensive set of spectral metering tools: you can switch between input, output, stereo correlation and stereo balance spectrums. ย The spectral gain change meter that is always present on the user interface gives you an outline of the overall signal power change applied by the plug-inโs processing chain.
