Audio Product Development Engineer - DSP
Ensure high quality audio performance in GN headsets by porting, integrating, and validating audio DSP algorithms from reference platforms to specific target platforms (chipsets/OS/SDKs), securing robust, real time operation in mass produced products. Furthermore, troubleshooting complex audio DSP and platform-related issues, feeding insights back into the product development cycle.Key ResponsibilitiesAlgorithm porting, integration, and optimization to the target platforms.Port existing audio DSP algorithms (e.g., Noise reduction, Beamforming, AEC, EQ, ANC) from reference implementations to the specific target platforms.Embed the ported algorithm into the existing FW stack of the target platform, including defined interfaces, data flow, and control mechanism for seamless operation of headset’s overall system.Adapt and optimize code to target SDKs, toolchains, and audio frameworks while maintaining algorithm behavior and performance.Handle fixed‑point and floating‑point implementations, data formats, and platform‑specific constraints.Integrate DSP/HW modules of target platforms into overall audio signal chainUnderstand the flow of audio data from transducers through various DSP blocks and out to the speakers and transmission channels.Work with the platform’s specific hardware abstraction layer or audio peripherals (ADCs, DACs, I2S/PCM interfaces, transducers).Validation and verification of the ported algorithms and integrated modules.Develop and execute comprehensive test plans to verify the functionality and performance of individual DSP blocks and the complete audio signal chain.Regression test - ensure new changes or optimizations do not compromise the existing functionality.Debugging & problem solvingPerform low level debugging using debuggers, emulators, and specialized tools to diagnose issues within the DSP firmware, hardware registers, memory, and real time execution flow.Identify root causes of audio anomalies or unexpected behaviors that might be caused by DSP algorithms, hardware interactions, OS scheduling, or interference.Analyze field logs, audio recordings, and reported symptoms, then potentially developed specific diagnostic tools or FW builds for field testing. At the end, provide timely resolution and implement robust fixes.Audio system calibration and measurement tool developmentDevelop and implement FW or SW routines for factory calibration of transducers and other audio components to compensate unit-to-unit variation.Create internal tools or scripts for automated testing, debugging, and performance evaluation during development and manufacturing.Documentation & maintenanceDocument implementation detail, integration interfaces, configuration parameters, and test procedures.Ensure well-commented code, modular, and adherence to GN coding standards for future maintenance and scalability.Cross‑Functional CollaborationWork closely with Algorithm/DSP researchers, FW/SW engineers, and Acoustic Engineers to ensure the p...
