jamulus/ChangeLog

3.5.0git

  * added support for 64 samples OPUS packets in the client (if a sound card buffer size
    larger or equal than 128 samples is chosen, the legacy 128 samples OPUS packets are used)

  * refresh server list if the Central Server address type is changed

  * bug fix: the server welcome message may appear twice if the server list was double clicked


TODO mixer faders linear -> log gain is better: CalcFaderGain() -> x = -50:1:0; plot(x, (10 .^ (x / 10)))

TODO offer the Jamulus ASIO settingspanel in case of an ASIO ERROR to fix, e.g., incorrect sample rate (https://sourceforge.net/p/llcon/discussion/533517/thread/777663cf94/#035f)

TODO issue with Mac audio interface: https://sourceforge.net/p/llcon/discussion/software/thread/7c443f2ed9/#eeab

TODO let the user select all possible sound card buffer sizes, this should solve Ticket #53

TODO auto jitter buffer performance not good at 64 samples frame size -> to be checked again

TODO for different frame sizes (64/128) the start value of 6 for the jitter buffer might be too low

TODO store Central Server jamulus.server start scripts on the Repo (one for Central Server, one for Central Server North America)






3.4.7 (2020-04-11)

  * added support for alternative Central Servers to solve the 200 server registration limit (Ticket #50)

  * added support for 64 samples frame size in the server (if server runs in 64 or 128 samples
    mode it is still compatible to both, 64 and 128 samples frame size clients)

  * added multichannel CoreAudio support, coded by emlynmac (#44)

  * fixed server not visible if in same local network, coded by pljones (Ticket #27)

  parameters to use depending on the upload limit and the number of connected
  clients)


2.1.4 (2009-02-15)

- added automatic jitter buffer size setting

  server according to the setting in the client (they are coupled now)
