Abstract
Embodiments described herein generally relate to measuring and evaluating a test signal generated by a device under test (DUT). In particular, the test signal generated by the DUT may be compared to a reference signal and scored based on the comparison. For example, a method may include: capturing a test signal from a device under test; splicing the test signal into a plurality of test audio files based on a plurality of frequency bins; at each frequency bin, comparing each of the plurality of test audio files to a corresponding reference audio file from among a plurality of reference audio files, the plurality of reference audio files being associated with a reference signal; and calculating a performance score of the device under test based on the comparisons.
Claims20
A method, comprising:
- capturing a test signal from a device under test (DUT);
- splicing the test signal into a plurality of test audio files based on a plurality of frequency bins;
- at each frequency bin, comparing each of the plurality of test audio files to a corresponding reference audio file from among a plurality of reference audio files to determine a spectral distance between each of the plurality of test audio files and the corresponding reference audio file, the plurality of reference audio files being associated with a reference signal;
- comparing the spectral distances to respective threshold values;
- and
- calculating a performance score of the DUT based on the comparisons.
A non-transitory, tangible computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:
- capturing a test signal from a device under test (DUT);
- splicing the test signal into a plurality of test audio files based on a plurality of frequency bins;
- at each frequency bin, comparing each of the plurality of test audio files to a corresponding reference audio file from among a plurality of reference audio files to determine a spectral distance between each of the plurality of test audio files and the corresponding reference audio file, the plurality of reference audio files being associated with a reference signal;
- comparing the spectral distances to respective threshold values;
- and
- calculating a performance score of the DUT based on the comparisons.
A device comprising:
- a memory storing instructions for measuring and evaluating a signal generated by a device under test (DUT);
- and
- a processor configured to execute the instructions, the instructions causing the processor to perform operations comprising:
- capturing a test signal from the DUT;
- slicing the test signal into a plurality of test audio files based on a plurality of frequency bins;
- at each frequency bin, comparing each of the plurality of test audio files to a corresponding reference audio file from among a plurality of reference audio files to determine a spectral distance between each of the plurality of test audio files and the corresponding reference audio file, the plurality of reference audio files being associated with a reference signal;
- comparing the spectral distances to respective threshold values;
- and
- calculating a performance score of the DUT based on the comparisons.
