The firmware used for the Omnia S1 is based on Google’s Android operating system. A custom audio driver and hardware were developed which are used by the Renderer to send bit-perfect digital audio via the digital outputs. It also allows Hi-Res PCM audio, DSD(DoP) and I2S playback through a compatible DAC.
1. The ARM CPU and firmware handle 32-bit/768kHz and DSD1024 decoding of any available music format.
2. Audio Processing Decoupled from CPU: To isolate the audio processing from performance degradation due to high CPU utilization or signal drop-off due to wireless congestion, the Omnia Audio Processor Unit (OAP Unit) operates independently from the CPU and provides caching of digital music and completely eliminates jitter.
Being a digital transport without the moving parts of a disc based system, the performance of the Omnia S1 surpasses most CD transports. The dedicated firmware designed for low latency playback enables a superior quality compared to typical PC or ARM based offerings.
