Spatial Audio SPARTA v1.5.0 VST WiN MACOS LiNUX [FREE] 0 (0)

SPARTA is a collection of flexible VST audio plug-ins for spatial audio production, reproduction and visualisation, developed primarily by members of the Acoustics Lab at Aalto University, Finland.

• Download links of current and past versions can be found here.
• The suite has been formally presented in this publication, with the source code made available here (GPLv3 license).
• The SPARTA installer also includes the COMPASS suite, the HO-DirAC suite, CroPaC Binaural Decoder, and the HO-SIRR room impulse response renderer. These plug-ins employ parametric processing and are signal-dependent, aiming to go beyond conventional linear Ambisonics by extracting meaningful parameters over time and subsequently employing them to map the input to the output in a more informed manner.
• For the curious researchers and/or spatial audio developers: note that the plugins included in the SPARTA installer are all built using the open-source Spatial_Audio_Framework (SAF).

List of plug-ins included in the SPARTA installerThe SPARTA suite:
• sparta_ambiBIN – A binaural ambisonic decoder (up to 7th order) with a built-in SOFA loader and head-tracking support via OSC messages. Includes: Least-Squares (LS), spatial re-sampling (SPR), time-alignment (TA), and magnitude least-squares (Mag-LS) decoding options.
• sparta_ambiDEC – A frequency-dependent loudspeaker ambisonic decoder (up to 7th order) with user specifiable loudspeaker directions (up to 64), which may be optionally imported via JSON configuration files. Includes: All-Round (AllRAD), Energy-Preserving (EPAD), Spatial (SAD), and Mode-Matching (MMD) ambisonic decoding options. The loudspeaker signals may also be binauralised for headphone playback.
• sparta_ambiDRC – A frequency-dependent dynamic range compressor for ambisonic signals (up to 7th order).
• sparta_ambiENC – An ambisonic encoder/panner (up to 7th order), with support for up to 64 input channels; the directions for which may also be imported via JSON configuration files.
• sparta_ambiRoomSim – A shoebox room simulator based on the image-source method, supporting multiple sources and ambisonic receivers..
• sparta_array2sh – A microphone array spatial encoder (up to 7th order), with presets for several commercially available A-format and higher-order microphone arrays. The plug-in can also present objective evaluation metrics for the currently selected configuration.
• sparta_beamformer – A spherical harmonic domain beamforming plug-in with multiple beamforming strategies (up to 64 output beams).
• sparta_binauraliser – A binaural panner (up to 64 input channels) with a built-in SOFA loader and head-tracking support via OSC messages.
• sparta_decorrelator – A simple multi-channel signal decorrelator (up to 64 input channels).
• sparta_dirass – A sound-field visualiser based on re-assigning the energy of beamformers. This re-assigment is based on DoA estimates extracted from “spatially-constrained” regions, which are centred around each beamformer look-direction.
• sparta_matrixconv – A basic matrix convolver with an optional partitioned convolution mode. The user need only specify the number of inputs and load the filters via a wav file.
• sparta_multiconv – A basic multi-channel convolver with an optional partitioned convolution mode. Unlike “MatrixConv”, this plug-in does not perform any matrixing. Instead, each input channel is convolved with the respective filter; i.e. numInputs = numFilters = numOutputs.
• sparta_panner – A frequency-dependent 3-D panner using the VBAP method (up to 64 inputs and outputs).
• sparta_powermap – A sound-field visualisation plug-in based on ambisonic signals as input (up to 7th order), with PWD/MVDR/MUSIC/Min-Norm options.
• sparta_rotator – A flexible ambisonic rotator (up to 7th order) with head-tracking support via OSC messages.
• sparta_sldoa – A frequency-dependent sound-field visualiser (up to 7th order), based on depicting the direction-of-arrival (DoA) estimates derived from spatially localised active-intensity vectors. The low frequency estimates are shown with blue icons, mid-frequencies with green, and high-frequencies with red.
• sparta_spreader – An arbitrary array (e.g. HRIRs or microphone array IRs) panner with coherent and incoherent spreading options.

The COMPASS suite:
• compass_binaural – A binaural ambisonic decoder (up to 3rd order input) based on the parametric COMPASS model, with a built-in SOFA loader and head-tracking support via OSC messages.
• compass_binauralVR – Same as the compass_binaural plugin, but also supporting listener translation around the receiver position and support for multiple simultaneous listeners.
• compass_decoder – A parametrically enhanced loudspeaker ambisonic decoder (up to 3rd order input).
• compass_gravitator – A parametric sound-field focussing plug-in.
• compass_sidechain – A plug-in that manipulates the spatial properties of one Ambisonic recording based on the spatial analysis of a different recording.
• compass_spatedit – A flexible spatial editing plug-in.
• compass_tracker – A multiple target acoustic tracker which can optionally steer a beamformer towards each target.
• compass_upmixer – An Ambisonic upmixer (1-3rd order input, 2-7th order output).

The HO-DirAC suite:
• hodirac_binaural – A binaural ambisonic decoder (up to 3rd order input) based on the parametric HO-DirAC model, with a built-in SOFA loader and head-tracking support via OSC messages.
• hodirac_decoder – A parametrically enhanced loudspeaker ambisonic decoder (up to 3rd order input).
• hodirac_upmixer – An Ambisonic upmixer (1-3rd order input, 2-7th order output).

Other:
• cropac_decoder – A binaural 1st order ambisonic decoder based on the parametric CroPaC model, with a built-in SOFA loader and head-tracking support via OSC messages.
• HOSIRR – An Ambisonic room impulse response (RIR) renderer for arbitrary loudspeaker setups, based on the Higher-order Spatial Impulse Response Rendering (HO-SIRR) algorithm;

Leo McCormack SPARTA v1.5.0 free VST audio plugin suite 0 (0)

SPARTA is a collection of flexible VST audio plug-ins for spatial audio production, reproduction and visualisation, developed primarily by members of the Acoustics Lab at Aalto University, Finland.

In particular, this release sees the addition of 9 new plug-ins:

– compass_binauralVR: essentially, this is the same as the compass_binaural plugin, except it also supports listener translation around the receiver position and multiple simultaneous listeners.

– compass_spatedit: a flexible spatial editing plug-in intended to be used with 2 instances. The first instance you make of the plugin will allow you to specify marker directions and it will output the beamformed signals, which you can then equalise/re-balance/modulate/swap/modify as you wish. These modified signals can then be routed to the second instance of the plug-in. The ambient components of the first plugin are then also sent internally to the second plugin instance. The edited sound-field is then reconstructed and outputted by the second instance of the plugin.

– compass_gravitator: a sound-field focussing plugin affecting only the direct sound components in the sound scene. It essentially pulls sound sources towards user defined marker directions with a certain degree of “gravitational pull”.

– hodirac_binaural: a parametrically enhanced binaural ambisonic decoder, based on the higher-order Directional Audio Coding (HO-DirAC) method

– hodirac_decoder: the loudspeaker decoder variant

– hodirac_upmixer: the ambisonic upmixing variant

– sparta_spreader: a source panner with coherent and incoherent source spreading options. While by default it loads HRIR data for binaural spreading, the approach is quite general; for example, you could also create synthetic microphone array recordings of spread sources if you wish, by simply loading a SOFA file of microphone array IR measurements instead.

– sparta_ambiRoomSim: a basic shoebox room simulator with Ambisonics output, based on the image-source method. Its main niche is that it supports multiple sources and Ambisonic receivers. The output audio for the receivers is stacked up to the 64 channel limit. e.g., you can have up to 16x1st order, 4x3rd order receivers, or 1x7th order receiver.

– sparta_decorrelator: a multi-channel signal decorrelator, which you can use to make reproduced sound scenes more diffuse when applied, e.g., after sparta_ambiDEC on the loudspeaker signals.
