SineMedia Electronics Technology

Sovereign technology.Next-generation sound.

From standards to silicon. China's complete sovereign audio technology stack.

Compute sound

Every channel. A clear path.

Follow digital audio through processing and out into the listening space.

Functional illustration based on V1.2 Preliminary, not physical silicon layers. Channels and coefficients are examples; the sound field excludes room reflections.

Digital input
Independent channels enter the APU.
TDM carries up to 64 input and 64 output channels. The three illustrated channels are independent digital sample streams.
4 × TDM16 input · 8 × TDM8 output
On-chip APU
Control and audio each have a clear path.
Cortex-M0 configures dedicated engines. The Router connects processing resources; dashed lines show control and solid lines show an example audio path.
128 FIR channels at 1024 taps · internal processing, not I/O
Output drive
From digital samples to speaker drive.
TDM sends the processed samples to external conversion and amplification, which drive the loudspeakers.
External conversion and amplification · system-dependent architecture
Sound field
Loudspeakers create the sound field.
Loudspeaker contributions combine at the listening position. Drive signals, array geometry and the room shape the result.
From loudspeaker radiation to a listening experience

Shape the sound field

Beyond channels. Into three dimensions.

32, 64 or 128 speakers across three layers. Choose a room and explore the listening position.

From speakers to the listenerGold points travel from each loudspeaker toward the listening position to illustrate direct propagation. This slowed animation does not represent air-particle motion, a measured sound field or SD64 rendering output.

Three layers, one spaceThe sky layer faces down. Middle and lower arrays surround the listening area at separate heights. Select a layer to highlight its speakers.

Array counts follow the project configuration. Room dimensions, layer splits, installation heights and listening positions are illustrative.
