One or more computer-readable storage media comprising instructions that, when executed by a computer, cause the computer to:

• determine an estimated respiration rate based on breathing audio data;
• and
• identify exhales in the breathing audio data using the estimated respiration rate.

A computer-implemented method for classifying the quality of breathing audio data as acceptable or unacceptable for use in determining or identifying one or more respiration features, the method comprising:

• acquiring breathing audio data;
• classifying the quality of the breathing audio data as acceptable or unacceptable for determining the one or more respiration features using a signal classifier trained by machine learning to classify the quality of breathing audio data as acceptable or unacceptable for determining or identifying the one or more respiration features.

A computer system for classifying the quality of breathing audio data as acceptable or unacceptable for use in determining or identifying one or more respiration features, the computer system comprising:

• a processor configured to classify the quality of the audio data as acceptable or unacceptable for determining the one or more respiration features using a signal classifier trained by machine learning to classify the quality of breathing audio data as acceptable or unacceptable for determining or identifying the one or more respiration features.
