World's first FPGA-based FIR acoustic calibration system
Different than any traditional DSP processing systems causing more phase problems, the core of SineMedia APC's technology lies in its cutting-edge SineCore audio processing platform with the revolutionary high-order real-time FPGA-based FIR acoustic phase calibration system that rejects the compromise between perfect digital audio algorithms and latency and reproduces the nature of sound by three-dimensional standards of sampling precision, sampling frequency and phase accuracy.

Ultra-low I/O latency
Theoretically DSP FIR filter is characterized by a linear phase that adapts to the unique audio requirement - that is, changing the frequency domain without causing phase changes. In real cases, however, Due to DSP inborn performance issues, those FIR filters with over ten thousands taps cannot meet the real-time audio performance requirements due to its long delay, deriving more new phase problems.
Therefore, for the first time, we have achieved low-latency performance and ensured that the filter runs without new phase delays by introducing high-performance FPGA parallel processing of high-order FIRs.
Everything is done in 10s
Traditional room correction systems is either too complicated or time consuming on setting up and measuring. However, APC's unique algorithm is different from those old-fashioned ways. It identifies the phse degradation simply using a microphone and delivers these problems to its Sonic Crystal software to generate a calibration solution automatically.
It was designed to be very easy-to-use but also highly precise and without compromise in terms of sound quality and/ flexibility for advanced users. You don't need to be technical, just set up measurement microphone and press the compute button, the system will do all the left work for you. Finally, an elevated standard listening area is reproduced in 10 seconds.
