Important
IP Audio Client V2.7 License: It is possible to install this new release of IP Audio Client onto a device that is running an un-licensed firmware, but once that is done it is not possible to go back to the unlicensed firmware, even if they are the same. i.e. If IPAC 2.7 is installed on an M400 SIP Opus 1.3.4 (which is unlicensed), the firmware will install, but it will not be possible to roll back to SIP Opus anymore. Another example: when updating firmware from previous IP Speaker versions (e.g. IP Speaker V2.6.2 or previous) it will be possible to update but not to roll back.
Change Log
New Features
RTP Source supports 2 different Playback Modes:
Regular Mode: plays back audio maintaining a constant delay, which is the same across multiple devices that are part of a system. This allows the possibility to keep a synchronized play-out. It should be used when playing BGM over RTP. When the RTP audio stream is received the switch to the RTP source is NOT instantaneous, it takes approximately 25 seconds before the stream starts to play. When playing back in regular mode the end to end delay is ~5 seconds.
Low Latency Mode: plays back with the lowest possible latency. It is a mode to be used for RTP paging, or short announcements received over RTP. When the RTP audio stream is received the switch to the RTP source is instantaneous. When playing back in Low Latency mode the end to end delay is between 130 - 200ms.
AES67 Operation mode: enable the possibility to discover, connect and play streams from third party systems supporting the AES67 standard, including Audinate Dante.
New source available: IC Paging. Allows the usage of IP Audio Client as an IC Paging endpoint that can receive paged announcement from any IC Paging Master station (e.g. PS Touch or Annuncicom PS1)
