She has made several recordings for international radio and television stations, among others for ATV and ORF (Austria). She has held masterclasses for the Kodály Society Wales (England), Masterclasses Gutenstein (Austria), International Masterclasses Györ (Hungary). She passionately teaches a piano class with young talents in Vienna and is frequently invited to serve as a jury member at international musical competitions. Performances at the following venues: in the Wiener Konzerthaus, at the Beethoven Festival Wien, at the Chopin Festival in Gaming (Austria), as well as at such places as the the Palazzo Albrizzi in Venice, the Museum of Fine Arts in Budapest, the National Theatre in Miskolc (Hungary), the Chopin Centre in Szafarnia (Poland), for the Chopin Center in Hamburg & Darmstadt (Germany), the Dutch Embassy in Vienna, the Dutch Embassy in Cairo (Egypt), the Dutch Embassy in Muscat (Oman), Vredenburg in Utrecht, de Doelen in Rotterdam, the Muziekcentrum Frits Philips, Eindhoven, the Hermitage Amsterdam (the Netherlands) and at prestigious festivals like the ‘Settimane musicali al Teatro Olimpico’, Vicenza and the Cello Festival in Dordrecht.Ĭlara has attended masterclasses held by Itamar Golan, Jan Wijn, Alan Weiss and Jean-Claude Vanden Eynden. Clara worked together with her husband, cellist Adam Javorkai (Bank Austria Artist of the Year in Austria 2009), cellists Pieter Wispelwey, Johannes Moser, Reinhard Latzko, tenor Ramón Vargas, mezzo-soprano Karin Strobos, writer Jan Brokken and members of the Royal Concertgebouw Orchestra. Clara often performs as a soloist, a chamber musician and as a song accompanist. In 2008, Clara was also a prize-winner at the‘18th International Chamber Music Competition Thessaloniki ’ in Greece. She is an award-winner at many international competitions, including the 1st Prize ( VSB Prize ) and the Youth Jury Prize at the Princess Christina Competition in the Netherlands, northern region (1996), the first prize in the category of chamber music and ‘ Primo Premio Assoluto ’ – the overall winner in all categories (respectively in duo with Ádám Jávorkai) at the international competition ‘ Premio Città di Padova ’, Italy (2008). Quite powerful.The Dutch-born pianist Clara Biermasz studied at the Academy of the Arts in Utrecht, the Netherlands, at the Franz Liszt Music Academy in Budapest, Hungary, and at the University of Music and Performing Arts in Vienna. The remaining filters were for SIP, only packets that indicated they were part of an I-Frame within the video RTP stream, and certain RTCP messages. Here I had filters for video RTP but had turned these off from the display. If I stopped the Video RTP lines from being displayed I could more carefully review the SIP, RTCP and audio RTP traffic on a better scale.īelow is another graph that shows packets instead of bandwidth. Clearly the RTP traffic is dominant here, but that’s OK because it was what I was looking for. The picture below is a sample where I was looking at the effects of TMMBR on the video stream and separated the video RTP traffic in each direction from the audio RTP (single line capturing both directions). Using multiple filters within the same graph puts all the various types of traffic together and paints a good picture of the traffic. In particular I like the ability to combine both and RTP port and source or destination IP address in a way that lets you separate audio and video RTP traffic as well as look at flows from and to a particular client or server side by side. This is also useful to understand the overall packets per second or bandwidth flows to and from clients, SBCs, SIP servers or media servers. I’ve used these combinations to verify at the effects of TMMBR as well as PLI on audio and video stream bandwidth (obviously PLI only for video…). Using wireshark’s built-in IO Graph tool (find it in the Statistics menu) along with filters for SIP, RTCP and RTP in combination with source or destination filters can create a powerful network visualization tool.
