Synchronized multichannel loopback within embedded architectures

A computer-program product embodied in a non-transitory computer readable medium that is programmed to prevent temporally misalignment between a reference signal and a measured signal for an embedded Linux system, the computer-program product comprising instructions to:

• receive the reference signal that is indicative of undesired audio content;
• receive the measured signal that is indicative of measured audio data in a listening environment;
• process the reference signal and the measured signal at a system on a chip (SoC) device;
• and
• merge the reference signal with the measured signal to provide a combined system input to a hardware layer of the SoC device prior to the combined system input being received at a plurality of software layers of the Linux system to prevent temporal misalignment between the reference signal and the measured signal caused by the plurality of software layers of the Linux system.

A computer-program product embodied in a non-transitory computer readable medium that is programmed to prevent temporally misalignment between a reference signal and a measured signal for an embedded Linux system, the computer-program product comprising instructions to:

• receive the reference signal that is indicative of output data for an adaptive control system;
• receive the measured signal;
• process the reference signal and the measured signal at a system on a chip (SoC) device;
• and
