{"added":null,"apiVersion":1,"behindSince":null,"buildDepends":[],"categories":["audio"],"comment":"Real-time convolution engine","compare":null,"dependentCount":null,"description":"Jconvolver is a Convolution Engine for JACK, based on FFT convolution and using\nnon-uniform partition sizes: small ones at the start of the IR and building up\nto the most efficient size further on. It can perform zero-delay processing with\nmoderate CPU load. Jconvolver uses the convolution engine designed for Aella, a\nconvolution application for reverberation processing (to be announced later).\nThis distributes the calculation over up to five threads, one for each partition\nsize, running at priorities just below the the one of JACK's processing thread.\nThis engine is a separate library that will be documented as soon as I can find\nthe time.\n\nMain features:\n* Any matrix of convolutions between up to up 64 inputs and 64 outputs, as long\n  as your CPU(s) can handle it.\n* Allows trading off CPU load to processing delay, and remains efficient even\n  when configured for zero delay.\n* Sparse and diagonal matrices are handled as efficiently as dense ones. No CPU\n  cycles or memory resources are wasted on empty cells in the matrix, nor on\n  empty partitions if IRs are of different length.\n`","flavors":[],"html":"https://daemonports.org/dragonfly/audio/jconvolver/","kind":"port","lastUpdate":null,"license":["GPLv3"],"maintainer":"yuri@FreeBSD.org","name":"jconvolver","newest":true,"newestVersion":"1.1.0","noVulnData":false,"origin":"audio/jconvolver","otherSystems":[{"maintainer":"yuri@FreeBSD.org","newest":true,"origin":"audio/jconvolver","path":"/audio/jconvolver/","system":"FreeBSD","version":"1.1.0_2"},{"maintainer":"yuri@FreeBSD.org","newest":true,"noVulnData":true,"origin":"audio/jconvolver","path":"","system":"HardenedBSD","version":"1.1.0_2"},{"maintainer":"yuri@FreeBSD.org","newest":true,"noVulnData":true,"origin":"audio/jconvolver","path":"","system":"GhostBSD","version":"1.1.0_2"}],"packages":null,"pkgName":"jconvolver-1.1.0_2","related":["audio/jmatconvol","audio/jnoisemeter","audio/py-zita-audiotools","audio/zita-alsa-pcmi","audio/zita-convolver","audio/zita-jclient","audio/zita-njbridge","devel/clthreads","devel/clxclient"],"repository":"DPorts","requiredBy":[],"requiredByCount":0,"runDepends":["audio/jack","audio/libsndfile","audio/zita-convolver","devel/clthreads","math/fftw3-float"],"status":null,"system":"dragonfly","systemLabel":"DragonFly","version":"1.1.0_2","versions":null,"vulnerabilities":null,"www":"https://kokkinizita.linuxaudio.org/linuxaudio/"}
