Guinea Pigs Ultrasonic Plus

(2 customer reviews)


A comprehensive anthology of Guinea pigs’ vocalisations and other characteristic sound effects. Single pigs: male, female, little ones, duets, trios and in groups of up to 9. Full spectrum of emotions from lively chatter to aggressive fast teeth clicking (yes, they click teeth!) and synchronous hysterical whining and scared ear-piercing squeals. Recorded simultaneously in EXTREME CLOSE UP with Nevaton and Sanken CO-100K microphones for full coverage from deep bass to rich ultrasonic content (and a mix of these two microphones is also provided for your convenience), as well as general CLOSE UP with Nevaton for more natural perspective. Guinea pigs are very social and vocal, but the sounds they make are so unexpected and weird, that they can greatly work not only for rodents, but for extraterrestrials or robots. Lots of ultrasonic content makes a perfect basis for speed and pitch manipulations.ย 10% of the library’s revenue goes to nature preserves and wild animal shelters.

Guinea pigs, or as they are also called โ€œcavyโ€ or โ€œCavia porcellusโ€ in Latin classification, produce a variety of absolutely strange and otherworldly sounds. They can be an endless source of inspiration for designing fantastic creature sounds โ€“ this was the reason for the first name of this library: “Extraterrestrials? – Guinea Pigs”.
We gathered 9 guinea pigs: 3 adult males, 3 adult females, one young girl 3 months old and very young brother and sister about 1 month old, each one with their unique character. We cared for our performers and tried to provide the best possible conditions for them including everyday walks on our lawn. If you know our Wolves library, with guinea pigs we mostly used the same principle of passive observation โ€“ setting up the mics and letting our talent live and play their social roles. Just with guinea pigs we were able to place the mics much closer because they donโ€™t jump up. Unexpectedly, recording and mastering the Guinea Pigs library turned out even more complicated than the Wolves library, these complications are covered in the corresponding blog post.
All recordings were made in an acoustically treated room and a special enclosure with damping padding was additionally constructed to minimize steps and movement noise. Each take was recorded from 2 perspectives: Extreme Close Up (ECU) โ€“ 10-15 cm from the source to the mics and Close Up (CU)โ€“ about 50 cm from the source.
For ECU we used a coincident rig of Nevaton MC59C cardioid and the only existing prototype of Nevaton MC59Twin, forming an LCR layout, and Sanken CO-100K for ultrasonic range. Since guinea pigs are small sound sources, only the center channel was used for single animals. LCR was used for groups of 2 and above, it gives a fantastic impression of being right inside the screaming guinea pigs havoc. In mastering Nevaton LCR and CO100K were mixed to stereo; Nevaton C and CO100K to mono. The library contains both individual mic files (LCR or MONO) and their optimized mixes (STEREO or MONO)
For CU of single animals either another Nevaton MC59C was used or just one channel of Nevaton MC50 LDC. For CU of groups – Nevaton MC50 in XY stereo.
Thus, each take is represented by 4 audio files in the library.

As with the Wolves library, since it is a library of real animals, I prefer to give context to my customers, so I do not cut recordings into very small bits, but present them in a file as sequences, phrases or small scenes with logical start and ending. So, the emotions are more understandable and lots of variations of a certain sound are available in the same file.
Very careful but thorough denoising and spectral editing were applied during the mastering stage, the files were checked, edited and mixed at different speeds to give you the best possibilities for further sound manipulation. This slowing down yielded a peculiar discovery: ย guinea pigs live and communicate much faster than humans. Some vocalizations of these rodents may seem a bit mechanical at the original speed, but when they are slowed down 4 times (25% speed), their emotions become much more obvious. We provide the same demo compilation at the original speed, half speed and quarter speed.


  • animals solo and in groups from 2 to 9
  • various emotions: calm, satisfied, friendly, enthusiastic, excited, hungry, sexually aroused, aggressive, scared and more
  • sounds include: squeaking, chatting, piercing squealing, purring, extremely low frequency rumbling, snorts
  • jaws sounds: teeth clicking, mouth clicking, chewing, gnawing
  • abrupt shakes with fur flapping, scratching oneself and more.
  • natural sequences of sounds are preserved
  • multiple takes of short one-shot sounds are compiled into bigger multi-take WAVs
  • only clean recordings of guinea pigsโ€™ vocal sounds with minimal movement noise like rustles and collisions went into the library. If there are steps and collisions in a file, they are mentioned in the File Name and Description.
  • The library preserves the natural large dynamic range of guinea pigs’ vocals. The Soundcloud demo employs dynamic range limiting to match the general loudness of other vendors’ demos
  • The library is divided into 268 files, from 67 different recorded takes. There are four different files using different mics per take: (1.) Nevaton MC59C and Nevaton MC59Twin, (2.) Sanken CO-100k and (3.) their MIX – recorded at Extreme Close Up perspective; and (4.) Nevaton MC59C or Nevaton MC50 at Close Up perspective
  • Total duration of the library is 35 min 50 sec multiplied by 4

  • As each guinea pig has a special voice and manner, I provide the names of them in CAPS in File Names, Description, and BWF Description. Then, when you find the sound of a particular animal you like, named DIVA, you can just search for DIVA.
  • Every audio file has the photo portrait of the corresponding guinea pig embedded into the Soundminer Artwork field to facilitate sorting and searching by Artwork. Photos are also included as jpg files for those who don’t use Soundminer

  • UCS: Universal Category System is fully implemented. Each single guinea pig or a certain group is represented by its own Vendor Category in the Filename, metadata and Artwork for easy sorting. UserData field contains microphone perspective and model
  • Soudminer, including personal names of the guinea pigs in CAPS in File Names, Description and BWF Description, wolves photos in the โ€œArtworkโ€ field, Open Tier field facilitates sorting by microphone perspective and microphone type or MIX.
  • BWF, some files have BWF Markers for interesting events
  • Tab delimited text file with all Soundminer fields exported
  • a folder with photos of the wolves as jpg files

  • Nevaton MC59C cardioid condenser microphone
  • Nevaton MC59Twin condenser microphone
  • Sanken CO-100K condenser microphone
  • Nevaton MC-50 Quad (double XY) large diaphragm condenser microphone
  • MixPre 10 II recorder

    Every sound designer should own this library. Dmitry’s incredible patience and attention to detail in the creation of this library is simply unparalleled. Coaxing so much amazing material from such tiny, quiet creatures was a daunting task that required hundreds of hours of sourcing, housing, feeding, recording, editing and mastering. And the sounds are extremely versatile as well — they lend themselves not only to your standard-issue guinea pig but to large creatures, supernatural beasts, aliens or super silly critters. Great job, Dmitry Chernov!

  2. Matt Klimek

    I cannot recommend This library enough. The amount of subtlety and emotion in the recordings is fantastic, and it was a core component in designing some cute alien critters.
