空间音频实时应用(SPARTA)

一个开源的VST音频插件套件,用于空间音频制作、复制和可视化

关于

SPARTA是一个灵活的VST音频插件的集合,用于空间音频的制作、复制和可视化,主要由芬兰阿尔托大学声学实验室的成员开发。

可在此处找到当前和过去版本的下载链接。
该套件已在本出版物中正式发布,其源代码在此处提供(GPLv3许可证)。
SPARTA安装程序还包括COMPASS套件、HO DirAC套件、CroPaC双耳解码器和HO-SIRR room脉冲响应渲染器。这些插件采用参数化处理,并依赖于信号,旨在超越传统的线性环境音,通过提有意义的参数随着时间的推移,然后利用它们以更知情的方式将输入映射到输出。
对于好奇的研究人员和/或空间音频开发人员:请注意,SPARTA安装程序中包含的插件都是使用开源空间音频框架(SAF)构建的。

Spatial Audio Real-Time Applications (SPARTA)
An open-source VST audio plug-in suite for spatial audio production, reproduction and visualisation

About
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.

List of plug-ins included in the SPARTA installer
The 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:

HOSIRR - An Ambisonic room impulse response (RIR) renderer for arbitrary loudspeaker setups, based on the Higher-order Spatial Impulse Response Rendering (HO-SIRR) algorithm;
