| + | ====== NPAPWS 2018 ====== | ||
| + | * Place: Miami, New World Symphony | ||
| + | * Date: 2018-04-24 to 2018-04-26 | ||
| + | * Programme: https:// | ||
| + | The following sections are based on Otto J Wittner' | ||
| + | ===== Panel discussion on itc's impact on music eduation ++ ===== | ||
| + | * Many opportunities... (bla bla) | ||
| + | * Network performaings arts at the stage now as motion pictures were in the beginning | ||
| + | * I.e. currently mostly recreating live conserts/ | ||
| + | * New unique productions will probably emerge over time | ||
| + | * Should we and can we compete with the real thing, i.e. live performances ? | ||
| + | * No, but online / virtual version should inspire the audience to visit live venues | ||
| + | * (Panel focus in general towards classical music.) | ||
| + | * (They seem to forget/ | ||
| + | * Question from audience raised this issue. Plan member admit all music should be listened to | ||
| + | |||
| + | ===== Panel on international collaborations ===== | ||
| + | * ( EaPConnect summary ) | ||
| + | * Music collaboration tools rigged in " | ||
| + | * Applied Nimbra hw boxes (120 KNOK for a pair !) | ||
| + | * A lot of activities emerged over the link | ||
| + | * Ref 196? experiment named "whole in space" (online link across US) | ||
| + | * Students are uncomfortable the first two-three sessions, but then start chatting over the link | ||
| + | * ( Claudio reports how music collab. tech. seem to disappear when it works properly ) | ||
| + | * Misc success stories where scepticle musicians (incl. professional conductor) are convinced when after trying music coll. tech. | ||
| + | |||
| + | ===== Recording Audio Across distance ===== | ||
| + | * Slide (ref picture taken on phone) showing latencies across orchestra and across US Internet topology | ||
| + | * Live clapping experiment showing have musicians deaccelerate when delaly is introduced and no visual reference is available. | ||
| + | * Popular music | ||
| + | * Microtiming is important, groove, fast percussion | ||
| + | * In studio: Click tracks, visual cues (no conductor) | ||
| + | * Latency issue are very different from classical (orchestra) music | ||
| + | * Collaboration between Berkely (and all its international campuses) and Napier in Edinburgh | ||
| + | * Example with el-guitar teaching session with 810ms rt delay | ||
| + | * Example of work composed assuming 3sec latency | ||
| + | * Example showing successful cross atlantic studio session with ~90ms return delay | ||
| + | * Delay test performed with studio musicians | ||
| + | * Ref Chris Chafe' | ||
| + | * Three musicians were given gradually increasing delay toward the other two musicians | ||
| + | * Deaccelleration begins at 35ms. A disaster av 60ms. | ||
| + | * Fast paced melody, some acceleration when delay is ̃~0ms, deacceleration starts around 35ms | ||
| + | * Drummer admit to "give up and just go with it" at 35ms | ||
| + | * Lola-cue-track and recordings at each end | ||
| + | * MUST run ProTools (or just the same DAW?) on both ends to enable " | ||
| + | |||
| + | ===== LOLA, Ultragrid and MVTP updates ===== | ||
| + | * LOLA | ||
| + | * Utilizes multiple cores in the hw | ||
| + | * Possible to downscale sessions to 20Mbps | ||
| + | * Attention needed to not configure sessions to require more resources than hw and network can provide | ||

| + | * End-to-end minimum delay ~30ms | ||
| + | * 120 fps uncompressed, | ||
| + | * Difficult with respect to light conditions | ||
| + | * Normal conditions give end-to-end ~40ms | ||
| + | * uncompressed 60hz 4k video | ||
| + | * All-equipment-in-one-box option developed, base don laptop and external capture cards | ||
| + | * GUI | ||
| + | * Minimum setup: Camera selection, display selection (and/or preview), Video and audio compression, | ||
| + | * Community update | ||
| + | * UG applied for voice master classes | ||
| + | * UG and LOLA has been applied together in event (Near in the distance 3) | ||
| + | * UG applied for live concert distribution i US from theater to schools and libraries | ||
| + | * Limited link capacity | ||
| + | * Old hw | ||
| + | |||
| + | * MVTP video transmission units | ||
| + | * Smaller unit: 2x full HD (1080p60), Larger supportes 4xHD | ||
| + | * 2 ch audio per video stream, 24 bit 48khz (?) | ||
| + | * Add < 1ms latency due to compression and transmission | ||
| + | * Compression ratio 5:1 or 10:1 with film industry quality | ||
| + | * Dream Chip Technology cameras: HD and 4k 6hz versions | ||
| + | * Only 0.1ms delay from sensor to sdi output ! | ||
| + | * ... not including shutter time, i.e. 1/fps | ||
| + | * SDI cameras are superior to USB cameras w.r.t. image quality | ||
| + | * Low delay SDI cameras exist !! | ||
| + | |||
| + | |||
| + | ===== On the Fringe ===== | ||
| + | * Common difficulties for " | ||
| + | * Tools that work | ||
| + | * JamKazam | ||
| + | * From 2014, standard audio intercase | ||
| + | * Without latency (?), no feedback issues (?) | ||
| + | * Sw with network monitoring, audio monitoring, ++ | ||
| + | * Multi web cam support | ||
| + | * Chat and backtalk channel | ||
| + | * Fees for lessons and JamTracks, otherwise free to use | ||
| + | * Demo: 130k incoming audio (!) A lot of packet-loss | ||
| + | * Legal issues? On session initiation you choose which copyright license should apply | ||
| + | * In general well developed piece of sw, especially to be freely downloadable | ||
| + | * Codec ? Now codec, raw audio (Really? At 130kbps ?) | ||
| + | * | ||
| + | * Artsmesh | ||
| + | * Build on Jack API and ffmpeg | ||
| + | * Need to be bought via the crypto currency Ethereum | ||
| + | * $100 dollar for purchase | ||
| + | |||
| + | ===== What about wireless? ===== | ||
| + | * 5G networks will make architecture merge with the Internet | ||
| + | * Due to screen + camera technology and high bandwidth | ||
| + | * ... or via virtual reality head-sets | ||
| + | * More sensors will be applied, e.g. | ||
| + | * Sensor in bow for violins | ||
| + | * Haptic gloves | ||
| + | * 3D audio | ||
| + | * " | ||
| + | * Vision: Include artists from where they are => wireless technology essential | ||
| + | * 5G are suppose to provide ultra-low latency... (probably only close to what wired nets provide) | ||
| + | * Illustration showing 5G cell example with also indoor cells | ||
| + | * Experiments with 4G shows 200ms end-to-end latency (Pipeline: web-cam ... 4G... some display) | ||
| + | * 4G is suppose to introduce around 40ms delay. 5G are to improve upon this. | ||
| + | * 3D sound | ||
| + | * Use surround speaker system rather than some headset | ||
| + | * (A lot of details about 5 channel 3d audio experiments) | ||
| + | * Capturing and representing audio reflections of higher degree is important | ||
| + | * Q&A | ||
| + | * How will 5G handle interference and other radio wave challenges? Similar to 4G, but also apply beam forming to focus radio coverage to smaller areas | ||
| + | |||
| + | ===== Producing and staging network performances ===== | ||
| + | * Ian Biscoe, Renate Kreil, Maria Isabel Gandia | ||
| + | * Project including Cuba and Havanna in a networked perfomance | ||
| + | * Hardly no Internet networks available | ||
| + | * A lot of enthusiasm required | ||
| + | * Language challenges | ||
| + | * Good partners / helpers important | ||
| + | * E.g. an american with Cuban friends in the sw business | ||
| + | * Local solutions: E.g. green screen based on curtains fixed with tape to wall | ||
| + | * Elector acoustics based on vintage computer hw (e.g. commodore 64) | ||
| + | * Project shown at NPAPWS 2017 in Copenhagen | ||
| + | |||
| + | * Net arts coordination center - https:// | ||
| + | * Recommend to set up a web site as the first step in a networked performance projects | ||
| + | * For advertising first, and for documentation later | ||
| + | * So far always aim for new challenges, e.g. new scales (no of sites / participants) og tool combinations | ||
| + | * Time frame for larger project is around two years | ||
| + | * Recording of show shown combining LOLA and Ultragrid | ||
| + | * 3 remote participants (projected in background), | ||
| + | * 20 technicians at one end of production (Wienna side) | ||
| + | * 80 people in total all places together | ||
| + | |||
| + | * Univ Catalonia | ||
| + | * Check your Internet connection before planning performance | ||
| + | * In person meetings are valuable | ||
| + | * Interaction and cooperation with people from other cultures (with other languages) is necessary | ||
| + | * Be open and patient | ||
| + | * Funding: E.g. EaPConnect, city council | ||
| + | * Artists: Students enjoy participating | ||
| + | * Network " | ||
| + | * When applying green screens ALL colors need to be transmitted, | ||
| + | |||
| + | * Ian brings | ||
| + | * either his own bus with all that he needs or... | ||
| + | * A suitcase with converters and connectors as well as capture cards and graphics cards (?) | ||
| + | * Borrow computers, projectors and camera | ||
| + | * Ian integrates available systems by writing minor patches | ||
| + | * What about reliability? | ||
| + | * Too expensive unfortunately | ||
| + | * Tape down connectors | ||
