REVIEW: Mattia Cellotto - Metamorphosis

Company: Mattia Cellotto

Product: Metamorphosis

Price: $204

Our Rating: 4.8/5

Sound Designer Mattia Cellotto has built up a strong reputation for producing stunning sound effects libraries. Now with his latest offering Metamorphosis, Mattia gives us a huge selection of beautifully crafted sounds that blur the lines between synthetic and organic.

Weighing in at 10.6gb and containing a total of 342 files, Metamorphosis covers a diverse range of sonic material. You will find forceful impacts, detailed textures, and a wide selection of whooshes, bass drops, pass-bys, and many other sounds. The library is split up into 3 folders - Hybrid, Recorded and Synthesized. In general, the quality of the audio is pristine throughout this library, and you can really hear the detail and precision in each sound.


The Hybrid Section was created by manipulating the Recorded and Synthesized sounds and contains an assortment of impacts, pass-bys, whooshes risers and other abstract effects.

The sounds themselves are heavily stylized and have a larger-than-life feel to them. Everything is brimming with atmosphere and will easily give your projects a real sense of cinematic enhancement. The percussion sounds are especially strong and will be extremely effective in both sound design and musical applications.


The recorded sounds are further categorised into Brass instruments, Fireworks, Pass-Bys, Percussion, and Pyrotechnic sounds. The source audio has been enhanced to achieve a hyper-realistic aesthetic, whilst retaining the natural and grounded feel of an organic sound.

There are some really unique and useful sounds in here. Most notably, the brass instruments folder which contains some incredible drones and throbbing bass tones that are guaranteed to get the room shaking. The entire Recorded Section was captured at 384KHz with microphones capable of recording up to 200KHz along with conventional mics. The high sample rates make these sounds especially useful for pitching, stretching and general redesign.


All of the sounds in the synthesized section were created using the wavetable synth Serum. There is a fantastic selection of sounds covered, from bass tones, drones, impacts, rumbles, and textures. Mattia has done a great job of making the sound feel like they belong alongside the other elements of the library, which is easier said than done when using a digital synth. The synthesized sounds in this library would be extremely effective for use in trailer sound design, and certain areas of electronic music production.

In conclusion, Metamorphosis contains a vast array of incredibly high-quality and unique sounds, and would make a fine addition to any sound designers toolkit. The percussion and pyro effects are a particular standout from this library. We can see ourselves using this library to add cinematic enhancement with the percussion and hybrid sounds and to use the recorded sounds as a starting point for creating our own effects.
