Bama Box supplies a high-density AES67 RX/TX media engine for integrated Linux products and dedicated AoIP modules. Unified 256×256-channel full duplex is measured on the Arm reference platform. Module vendors and equipment OEMs keep control of the surrounding product architecture, interfaces and customer experience.

02 / THE TECHNOLOGYMove audio.
Move audio.
Not overhead.
Bama Box implements the AES67 receive and transmit media paths entirely in Linux userspace. It requires no custom kernel module and is portable across Linux-capable SoCs. Platform-specific timestamps, clocks and audio interfaces connect through a defined software API.

AES67↔RECEIVETIMING CONTROL+TRANSMITPACKET SCHEDULING↔ALSA
The unified media engine reduces avoidable processing and data movement in both directions, leaving more CPU and memory headroom for the OEM product.
MEASURED CLOCK-DRIFT CONTROLTwo clocks.
Two clocks.
One audio timeline.
Network time and the audio-device clock do not run at exactly the same rate. In the measured HiFiBerry/PCM5122 run, the device consumed approximately one extra 48 kHz PCM frame—20.83 µs—about every ten seconds.
The Bama Box controller tracked that drift and made six declared, single-frame repeats during the 60-second run, keeping the presentation timeline aligned instead of allowing phase error to accumulate.
Jitter + drift control
Protects the receiver target while tracking the device clock.
Packet scheduling
Moves product audio onto the network with controlled timing.
PTP time mapping
Uses the platform timestamp source through a defined OEM software API.
ALSA integration
Provides the Linux audio boundary for receive and transmit.
RX + TX TIMING CONTROL
Deterministic timing as density rises.
RTP timing drives receiver deadlines and transmit packet scheduling. OEM timestamps, platform clocks and audio interfaces connect through a dedicated software API.

03 / OEM LICENSINGPredictable economics.
Predictable economics.
Most of the value stays with you.
Production terms are structured to remain attractive even on platforms where the measured gain is at the conservative end of the performance range.
At shipment
No recurring subscription. The production royalty applies once when an enabled OEM product ships.
Aligned to capacity
Licensing follows the enabled network-audio channel class, keeping low-channel products economical.
Predictable maximum
A negotiated per-device ceiling prevents higher channel density from creating an open-ended royalty.
Your Linux SoC
Bring your i.MX7, i.MX8 or other target hardware for a confidential AES67 media-path benchmark before production commitment.
Exact pricing stays private. Volume, product-family, platform and strategic-rights terms are matched to the product and scope.
