    Water & Oceans (M)exican (S)easide Play Track 52 sounds included, 70 mins total $39
    Add to Wishlist

    Mexican Seaside is a unique Mid-Side collection of ocean sounds gathered during the summer of 2017 in the Yucatán Peninsula – Mexico. It contains sandy and rocky beach ambient sounds, with no human activity. These sounds were recorded at sunrise (on various days) with a Zoom H6 on a Joby GorillaPod and a MS capsule (MSH-6) covered by a Rycote Mini Windjammer. Mid-side allows you to actually adjust the width of the stereo image after it has been recorded. It provides total mono compatibility for recordings that may eventually be played back in mono, such as TV broadcasts.
    The package contains a MS-RAW folder plus a LR folder with all the files decoded to stereo for quick use.

    100% of “Mexican Seaside” SFX library purchases will be donated to UNICEF México.

  • Hum, Buzz & Glitches 3Dimensional Printing Play Track 95+ sounds included $49
    Add to Wishlist

    3Dimensional Printing is the multicolored result of different recording sessions of a couple of 3D printers (the Sharebot NG – Next Generation and the DeltaWASP 20 40) at Fabb and at FabLab Milan between 2014 and 2015.
    All the sounds were recorded directly as uncompressed .wav files through both a RME Fireface UCX and a Zoom H6 Portable Recorder.
    Duration ranges vary from 1 to 5 minutes, with the most sonically interesting excerpts from full printing cycles. Lots of pattern and sequences are available for selection and transformation.
    Five different transducers were chosen to capture all the sonic details of these mechanisms:
    – C-SERIES pro contact microphones, hand-made by Jez Riley French;
    – Barcus Berry 4000 Planar Wave System (Piezo crystal sensor+4000XL Piezo Preamp);
    – Piezo Film Tab Contact Microphones by Cold Gold Audio;
    – Custom Induction Coil Pick-up (also used to create the Unseen Noises collection);
    – Zoom MSH-6 MS Capsule (the stereo image of the Mid-Side recordings is rendered as balanced stereo LR files).

  • Nature & Countryside Insectus Play Track 300 sounds included, 50 mins total $69
    Add to Wishlist

    Do you want to add a bit of mystery, depth, tension to your ambience stem and influence the emotional state of the listener?

    Insectus is a special Ambisonics sfx library: we’ve been through lot of experimentation in that time with different approaches regarding the best way to deliver this bizarre package of sounds.

    So what is it exactly? Just think about the sound-designed material as a background sweetener. We’ve called it Insectus not only for its Latin roots, but also because it comes from the fusion of two word: Insect+Tinnitus.

    We used the higher octave of the spectrum in an odd way, mimicking insect vocalization and biophony sounds in Symbolic Sound Kyma by layering a lot of synthesised stream of small band of very high frequencies (hence the inspireful source name Tinnitus).

    Now you can create soundscape by layering, rotating, expanding and shrinking the FuMa/ambiX file. You can also re-construct the 360° sound panorama from binaural up to 7.1 surround.

    You’ll find 100 loopable variations of FOA FuMa/ambiX interleaved files (4 channels), with a duration of 30 seconds each.

  • Drones & Moods Kyma Ambiences – vol.1 Play Track 56 sounds included, 112 mins total From: $49
    Add to Wishlist

    Kyma Ambiences [USO003] is the third sound effects bundle created by Matteo Milani.

    The generation of these “Artificial Reality Ambiences” starts entirely in Symbolic Sound Kyma from the processing of white and pink noise by filtering – in the time/spectral domains – and convolving these sources with custom FM, additive, formant and granular synthesis.

 The composition’s resource of sound material is drawn solely from these processed stochastic sound elements: coloured noise is a raw material already full of life and can be sculpted into a variety of temporal forms, movements and textures.

    The interaction with Kyma was typical of a composer who explored a device’s potential for sound transformation like a musical instrument. The goal was to obtain an organic and acoustic quality using only a restricted sound source, in order to evoke real spatial characteristics attached to each invented sound.

    The “Kyma Ambiences vol.1” sound effects collection is published @ 96kHz (native) – and is also available as dual-layer separated “Elements”, suitable for recombinant stratification, varispeed and spatial positioning in the surround field (for a total of 112 files @ 96kHz).

  • Drones & Moods Kyma Ambiences – vol.2 Play Track 100 sounds included From: $49
    Add to Wishlist

    Kyma Ambiences vol.2 follows the traces of the original collection dated back 2013, but this time it’s bigger and immersive. It contains 100 abstract and evolving ambiences created with our beloved Kyma sound design workstation. Due to the increasing demand of spatialized content for game and VR/AR project, this inspiring collection has been entirely designed as a spherical representation of sound natively in 3rd Order Ambisonics by generating all the Sounds in Kyma and mastering them in Pro Tools through a custom analog setup (Looptrotter Sa2Rate+Elysia xfilter 500+TK Audio BC501).

    Ambisonics is a multi-channel technology that lets you spherically capture the sound arriving from all directions, at a single point in space. I used state of the art tools to forge these modern and cinematic soundscapes by blending many encoders to inject different colours into the design process. Each virtual 3D sound environment has been carefully constructed by layering and placing Kyma Sounds at different locations in a virtual three dimensional field using the Audio Ease 360 pan suite. I captured real spatial sound with the AMBEO VR Mic to be encoded-transformed-decoded using Kyma Ambisonic Tookit (1st Order) and then up-mixed to 3rd Order with Harpex-X and PerfectSurround Penteo 16 Pro to extract the maximum amount of spatial information.

  • Cars Monaco Grand Prix 2018 Play Track 334 sounds included From: $99
    Add to Wishlist

    We’re proud to release our first premier race ambience library, as we continue our exciting journey in sound experimentation with spatial audio. The Monaco Grand Prix 2018 is a genuine sonic document of the 76th edition of the Grand Prix Automobile de Monaco, the world’s most glamorous race.
    If you’re looking for unique and modern race engine sounds and ambiences to use in your commercial, movie, television or game projects, here you’ll find lot of sounds with different perspectives to start building real and tactile sport soundscapes.
    We made use of two favourite Ambisonics microphones: the Sennheiser Ambeo and the classic Soundfield SPS200, recorded across our Sonosax gear (SX-R4+, SX-R4, SX-M32) and their amazing preamps, which digested the high SPLs of the high-performance cars.
    But that’s not all: you’ll also find extremely accurate stereo recordings made with a Sanken CSS-5, an A-B Stereo Technique configuration with a couple of omnidirectional DPA 4060 and, last but not least, a custom MS rig based on a Schoeps MK 41 supercardioid capsule (Mid), plus a MK 8 figure-8 capsule (Side), amplified by their respective CMC 6 units.
    Looking for radical transformations? We recorded everything @ 96 kHz, so if you want to turn a pass-by into a dramatic spaceship pass, you’ll be free from any sonic artifacts.

  • Trains Runaway Trains Play Track 216 sounds included, 118 mins total $79
    Add to Wishlist

    Immerse yourself in the second library of the Ambisonics series by USO. These “Runaway Trains” were recorded with a Senneheiser Ambeo and a Sonosax R4+ in and around the Milano Greco Pirelli railway station, which is part of the so-called “Milan Circle Line,” a railway loop which circumnavigates the city.
    The library contains a lot of passing trains and ambient sounds recorded very close to the railway, both by day and by night. There has been no further processing, although I did carefully remove all the Italian P.A. announcements, to make life easier for the editors during the sound montage.
    A useful bonus, too: you will find some ready-to-use backgrounds as “airfill” between the passing trains to create continuity in a longer scene, if need be. The ambient sounds are also great as a standalone!

  • Hum, Buzz & Glitches Transmission Apparatus Play Track 373 sounds included From: $49
    Add to Wishlist

    Transmission apparatus is a construction kit designed to create a broad range of communication sounds, from real to “alien” broadcasting signals.

    The library contains more than 2 GB of data, delivered in 373 files of unique sound material. It’s catalogued in five elements: AM (amplitude modulation), FM (frequency modulation), SSB (single side band – aka ham radio), KYMA (synthesised noises) and VOCAL (unintelligible speeches).

    The first three bands were recorded from the output of different radio receivers at 96 kHz via a Crane Song HEDD (Harmonically Enhanced Digital Device) to add warmth and tube/analog sonic color to the recordings. All the samples have been carefully selected from these recording sessions, with the addition of just a little dsp processing to widen the stereo field.

    The Kyma folder also contains unique audio files entirely synthesised in the SSC Kyma+Paca(rana) environment. A group of SFX called Vocal is the result of “destroyed” dialogues and vocal sources via spectral processing.

    Transmission Apparatus is available in two versions:

    96 kHz .WAV version• Audio Format: Broadcast Wave Files (.wav)
    • Bit Depth: 24-bit Size: 2.49 GB
    • Download size is 1.82 GB (compressed .rar archive)

  • Hum, Buzz & Glitches Unseen Noises Play Track 40 sounds included $40
    Add to Wishlist

    Electromagnetic informations are invisible and omnipresent. In every city, especially the big ones, an infinite number of electromagnetic waves is hidden: we can’t hear them, but they’re everywhere! Unseen Noises explores the “invisible” noise pollution transducing electromagnetic fields into audio signals with a telephone pickup: it acts like a radio antenna for hum and weird electromagnetic noises.

    “We used telephone tap coils that receive electromagnetic signals around us and convert them into audible information to discover invisible and surprising aspects of the environment in which we live in.

    To widen our sound palette, we explored cell phones, tablets, light systems, automated teller machines, wireless communication systems, anti-theft security devices, surveillance cameras, computers, navigation systems, wireless Internet routers, neon advertisings, public transportation networks.

    We just used the system of electromagnetic induction as way of amplifying musical sounds. Our efforts were focused on finding “articulated” behaviours and other musical qualities in them.

    Note that the files contained in “Unseen Noises” are real performances executed on different devices without editing.” – Matteo Milani
