Filterbank rule for spherical microphone array encoding and EQs for above aliasing, transducers, and binaural playback
No full textCompact rigid-sphere microphone arrays are used to record 3D-sound scenes from one recording perspective. They are often used as the main microphone array in field recordings using Ambisonics. For time-invariant Ambisonic encoding, the array signals are typically first decomposed into spherical harmonic coefficient signals by a matrix, which are then equalized by radial filters, which need to be regularized by, e.g., a filter bank. This paper shows: (i) a simple way to determine common transducer responses for equalization based on comparison with an omnidirectional reference, (ii) a heuristic rule to define the filterbank frequencies depending on the Ambisonic order, diffuse-field-normalized weightings basic or max-rE, and available SNR, (iii) the appropriate handling of frequencies above the arrays spatial aliasing limit, and finally while the proposed solution supports loudspeaker playback: (iv) binaural playback requires a different equalization

Assessment of Simulations in FAUST and TASCAR for the Development of Audio Algorithms in Acoustic Environments
No full textTesting real-time capable audio algorithms in a time-variant acoustic environment can be a tedious process, often requiring specialised hardware to fulfil latency constraints. In this publication, an alternative approach based on an acoustic scene simulation in TASCAR and signal processing using FAUST is assessed and tested against actual measurements. In dry acoustic environments, a good match of level distribution and spatial coherence at various evaluated points can be observed when modelling direct sound and early reflections. A simulation of an ANC algorithm shows also comparable performance to a measurement-based reference. Larger deviations are observed for reverberant and anisotropic scenarios. The proposed toolchain can be used for low-cost development and assessment of real-time capable algorithms in time-variant acoustic scenarios, as all parameters and virtual positions can be updated during operation
