Technical FAQ

Q1: Does this module require custom drivers for Android or Linux? A: No. The SS-4M-DSP360-I utilizes the standard USB 2.0 Audio Class (UAC) protocol. It is Plug-and-Play on Android, Linux (Kernel 2.6.24+), and Windows, allowing for immediate 4-channel synchronized audio capture.

Q2: How does the integrated FPU benefit the audio quality? A: The Floating Point Unit (FPU) allows the DSP to perform complex AI noise reduction and echo cancellation algorithms with much higher precision and lower latency compared to standard fixed-point processors, resulting in more natural and clearer voice output.

Q3: Can this module handle both recording and playback simultaneously? A: Yes. With support for 2-channel Line-out and uplink/downlink noise reduction, it manages full-duplex audio communication, making it perfect for two-way intercoms and video conferencing.

Q4: Is the coordinate output available for sound source localization? A: While this specific model focuses on high-fidelity 4-channel capture and DSP enhancement, the 4-channel raw data can be processed by the host system for DOA (Direction of Arrival) estimation.
