ALSA-AES67-Streaming

A virtual AES67 based ALSA-audio driver which can receive and send RTP-audio packets in the local Network. At the moment without PTP-Support!

Features

• Native virtual ALSA-Deivce driver without additional user space daemon
• support for 44,1 kHz and 48 kHz Samplerate
• support for 16 Bit and 24 Bit Sample depth
• definable Packet Size
• configurable IP-Settings
• configuration via Sysfs
