MONO Streaming: MPEG1/2 Layer 3, VBR (Fs:48KHz): 72 76 80 88 96 112 144 160kbps
STEREO Streaming : MPEG1/2 Layer 3, VBR (Fs:48KHz): 88 96 104 120 144 160 176 192kbps
Protocols IP standard based protocols; TCP/IP, UDP, HTTP, ICMP, SNMP
Supports BootP, DHCP and Auto IP.
Supports
RTP for low latency audio streaming.
Latency (time delay) ADA102 has a latency of only 20 mS (uncompressed audio) on LAN
Variable Bit Rate (VBR)
Encoding
The encoder uses Variable Bitrate Encoding (VBR) to realize optimal compression of the audio
data. The setting of a fixed bitrate is replaced with setting a quality level that preserves audio
quality in critical sections and enhances compression otherwise.
