Determination of noise presence in recorded sounds

An electronic device, comprising:

• a first recording device;
• a connector to couple to a second recording device;
• a multiplexer coupled to a playback device;
• a processor coupled to the first recording device, the connector, and the multiplexer;
• and
• a storage device coupled to the processor, the storage device comprising machine-readable instructions which, when executed, cause the processor to:
• select the first recording device;
• cause the multiplexer to select the playback device;
• cause the playback device to produce a first sound using a first audio file;
• cause the first recording device to record the first sound;
• detect, in the first sound, a noise not present in the first audio file;
• select the second recording device;
• cause the playback device to produce a second sound using a second audio file;
• cause the second recording device to record the second sound;
• compare the recorded first sound to the recorded second sound;
• and
• determine, based on the comparison, a source of the noise.

A method, comprising:

• producing, by a first playback device, a first sound using a first audio file;
• recording, by a recording device, the first sound;
• detecting, in the recorded first sound, a noise not present in the first audio file;
• producing, by a second playback device, a second sound using a second audio file;
• recording, by the recording device, the second sound;
• comparing the recorded first sound to the recorded second sound;
• and
• determining, based on the comparison, a source of the noise.
