Universal Spatial Audio Transcoder
Amaia Sagasti, Davide Scaini, Daniel Arteaga
This paper addresses the challenges associated with both the conversion between different spatial audio formats and the decoding of a spatial audio format to a specific loudspeaker…
Mono-to-stereo through parametric stereo generation
Joan Serrà, Davide Scaini, Santiago Pascual +4
Generating a stereophonic presentation from a monophonic audio signal is a challenging open task, especially if the goal is to obtain a realistic spatial imaging with a specific pa…
Universal Speech Enhancement with Score-based Diffusion
Joan Serrà, Santiago Pascual, Jordi Pons +2
Removing background noise from speech audio has been the subject of considerable effort, especially in recent years due to the rise of virtual communication and amateur recordings.…
Upsampling layers for music source separation
Jordi Pons, Joan Serrà, Santiago Pascual +3
Upsampling artifacts are caused by problematic upsampling layers and due to spectral replicas that emerge while upsampling. Also, depending on the used upsampling layer, such artif…
Wavelet-based spatial audio framework
Davide Scaini
Ambisonics is a complete theory for spatial audio whose building blocks are the spherical harmonics. Some of the drawbacks of low order Ambisonics, like poor source directivity and…
