Method for wirelessly synchronizing electronic devices

A method of determining the clock drift between a first electronic device and a second electronic device, the method comprising:

• injecting a plurality of audio signals to the audio output channel of a first device and detecting injection parameters of the plurality of audio signals at the time when the plurality of audio signals are injected to the audio output channel of the first device;
• detecting injection parameters of the plurality of audio signals at the time when the plurality of audio signals are injected to the audio input channel of the second device;
• injecting a plurality of audio signals generated by the second device into the audio input channel of the first device and detecting injection parameters at the time when the plurality of audio signals generated by the second device are injected into the audio input channel of the first device,
• injecting the plurality of audio signals generated by the second device into the audio input channel of the second electronic device and detecting injection parameters at the time when the plurality of audio signals generated by the second electronic device are injected into the audio input channel of the second electronic device;
• and
• determining a clock drift between the first electronic device and the second electronic device based on the detected injection parameters.
