Sound Particles is an immersive audio software capable of generating thousands (even millions) of sounds in a virtual 3D audio world. Creating highly complex sounds has never been this quick.

Sound Particles Indie Perpetual Licence is for independent users (note that this is not the professional user licence for companies, which is sold here >>). This immersive audio application enables independent audio professionals and enthusiasts from all industries, working in all genres of audio production to efficiently create highly complex sounds and render the results for discrete channel playback through virtually any speaker setup, from mono to Atmos. Transform one voice into the sound of a crowd of thousands, or a few gunshots into a full battlefield, the sounds created within Sound Particles are limited only by the imagination. Let your creativity flow and be amazed at the soundscapes you achieve using Sound Particles.

All New Engine
The 2.1 update incorporates a new audio engine, responding to real-time changes with optimized iterations, delivering your sound design in the best audio quality possible.

Batch Processing
Create your session and set Sound Particles to output hundreds of different renders in one pass. This feature makes mass production of sound effects a reality.

Track Presets
Create and save an infinite number of track and microphone settings, recall track setups with just two mouse clicks. Includes 100+ professionally crafted presets.

User Templates
Save your sessions as templates. Include any number of tracks or microphones, never start from scratch again.

Enable / Disable
Enable or disable audio files, movement or audio modifiers. Experimenting with different techniques was never as easy as it is with version 2.1.

CGI Integration
Working on animations or cinematics? Import 3D information from animations or visual effects into Sound Particles and attach sound to 3D objects in order to make your mix quicker than ever.

Real-time Rendering
Sound Particles now lets you hear, in real-time, the changes you perform. Adjust every parameter you desire, and the rendering process will automatically adapt to the changes.

Binaural Monitoring
Sound Particles will let you monitor binaural audio by decoding any type of audio format. Additionally, by using Ambisonics virtual microphones and the VR Client application, you can monitor your mix with head-tracking while watching a 360 video.

VR Client App
Test Sound Particles virtual reality projects on your Android device using this mobile application which communicates directly with the desktop application via IP. Includes 360 video, Ambisonics and head-tracking support.

Up to Millions of Particles
You can use thousands or even millions of sound sources playing at the same time. By adding audio modifiers, you create sound variations to make sure that each particle sound slightly different from any other particles.

Particle Groups and Particle Emitters
When using particles, you can either use particle groups or particle emitters. Particle groups create all particles at the same time (although random delays can be added). Particle emitters create particles in a constant rate. Also, with particle emitters, you can move the emitter and the particles with different movement modifiers.

Import Audio Files
Sound Particles doesn't synthesize sound. You will need to import one or more audio files (this is what is reproduced by the particles). If you import a single audio file, then all particles will reproduce the same file. If you have more than one file, then each particle will randomly select one of the available files for reproduction. Of course, you can add audio modifiers to create variations (random audio effects applied to each particle) or to reproduce only a small slot of the audio file (granular).

Audio Modifiers
Add audio modifiers to create much more diversity between particles. These random effects can range from simple things like random gains or random delays, to more complex things like random filters (EQ), random sub-bands (each particle reproduces only a sub-band of the spectrum), random pitch-shifters (varispeed) or granular modifiers.

Granular Modifier
By default, each particle will reproduce the entire audio file that have been selected for that particle. But, by using a granular modifier, each particle will only reproduce a small fragment of the sound. Available parameters: variable/fixed size, maximum duration of the slot, window (fade-in/fade-out), etc.)

Movement
Add movement to your particles, either by using Keyframe Animation or by using Movement Modifiers.

Keyframe Animation + Automation
Keyframe animation is widely used in computer graphics to animate things (it’s like automation). You specify what you want in 2 time instants, and the computer will interpolate everything in-between. For instance, you say that particles should start as a circle with 10 meters of radius and change to 30 meters 10 seconds later. Remember that Sound Particles also works with single sources. As such, you can say where do you want to place the sound source in special instants, and the computer will animate the sound source accordingly. Use automation to control parameters thru time, including audio modifier parameters. By using randomness and automation, you will create fantastic results. For instance, imagine 100 particles with random pitch-shifters converging to a specific value.

Movement Modifiers
Movement Modifiers allow you to add random movements to the particles – random velocities, rotation movements around the center, accelerations, etc.

Virtual Microphones
The virtual microphone acts like a sound camera, capturing sound from a special perspective. You can use several microphones at the same time, either to capture sound from different places or to capture sound in different formats. Sound Particles support mono (omni, cardioid, hypercardioid, figure-of-eight), stereo pairs (XY, MS, AB, Blumlein, Decca Tree, ORTF), Ambisonics (up to 6th order), Multichannel (5.1, 7.1), Immersive (Dolby Atmos 9.1 bed, Auro 11.1/13.1, NHK 22.2) or any custom speaker configuration that you may have.

Ambisonics (HOA)
Do you work with Ambisonics? Great… Sound Particles can render audio in Ambisonics up to 6th order (ACN/FuMa/SID, N3D/SN3D/maxN).

Immersive Audio
Use height information in your sound. Sound Particles supports the recent immersive formats like Dolby Atmos 9.1 (bed), Auro 11.1/13.1, NHK 22.2, or even Ambisonics (including High-Order Ambisonics (HOA) up to 6th order). Or simply create your own custom setups, with speakers on the ceiling.

Custom Speaker Layouts
Sound Particles allows you to create custom speaker layouts to be used by the virtual microphones. If you are creating sounds for theater or parks, use this feature to render audio for your own custom speaker configuration. You can still render the scene in your control room setup (e.g. 5.1) but then re-render it for that “strange” setup configuration that you really need. For instance, the software is being tested by Disney as a sound design tool because of the custom speaker configurations in their parks around the work.

Controlled Randomness
The use of random values gives you fantastic organic results, but with full control over such randomness. For each parameter of the particles, choose the best random distribution and its characteristics. With a bit of imagination, you will get fantastic results.

Doppler and Propagation
If a particle moves, the Doppler effect is there. Do you want a different speed of sound? Do you want to disable Doppler for a musical application? Do you want to change the propagation attenuation to better control the balance between near/far away particles?

3D Views
Have a perfect view of what is happening, using different views of the world you are creating: top view, front view, left view, right view, perspective view, video view and spherical view (imagine the 3D soundfield converted to a single 2D image, like a map of the Earth).

Units
What do you prefer to work with? Inches? Meters? Miles per Hour? Meters per second? Radians? Choose the units you prefer to work with.

Need a Different Take?
Since particles use random generators, you can easily create different takes of the same scene. Simply press the “recreate new particles” button, and you will get a new set of particles which will sound slightly different – a new take on the same scene.

Video Integration
Import a video clip to sync sound with image. By using a spherical view, you can even see particles on top of the image, allowing you to have not only the best time sync, but also the best space sync, placing sounds accordingly with the image of the video.

Virtual Reality (VR)
To those that work with virtual reality, Sound Particles can be a very helpful tool. Import your 360 videos, and place the sounds (single particles) when they happen and where they happen. Use keyframe animation to animate them perfectly in sync with the image.

Sound Quality
All audio processing is done at 64-bit floating-point precision. Why? Because we mix thousands or millions of sound sources, and because we need a huge dynamic range since we can be rendering explosions happening at a few inches from the virtual microphone or a single whisper several miles away. After rendering, a normalization is applied to optimize the dynamic range of the output audio. Sound Particles supports the usual sample rates (44.1 ... 192 kHz), but also strange sample rate values, if you desire. In terms of time precision, Sound Particles calculates everything at each audio sample.
