Mechanical device for auditory encoding of respiration flow and volume metrics using a mobile device

A computer-implemented method, comprising:

• obtaining, using a spirometric encoding device comprising a spirometric encoding assembly, air generated by a breathing of a user;
• capturing, using a microphone, audible breath data generated by the spirometric encoding assembly comprising a sound encoder assembly, wherein the audible breath data comprises a series of frequency spikes or shifts in acoustic frequency proportional to a flow of air through the spirometric encoding assembly;
• generating a signal representation of the audible breath data;
• calculating, based on the signal representation, a flow rate for the breathing of the user;
• and
• calculating, based on the flow rate and a cross sectional area of a breathing tube of the spirometric encoding device, a volume for the breathing of the user.

A computer-implemented method, comprising:

• obtaining, using a spirometric encoding device comprising a spirometric encoding assembly, air generated by a breathing of a user;
• generating, using a speaker, a reference tone;
• capturing, using a microphone, the reference tone and audible breath data generated by the spirometric encoding assembly comprising a sound encoder assembly, wherein the audible breath data comprises a series of frequency spikes or shifts in acoustic frequency proportional to a flow of air through the spirometric encoding assembly;
• heterodyning the reference tone and the audible breath data to generate generating a signal representation of the breathing of the user;
• calculating, based on the signal representation, a flow rate for the breathing of the user;
• and
• calculating, based on the flow rate and a cross sectional area of a breathing tube of the spirometric encoding device, a volume for the breathing of the user.
