Clock synchronization techniques including modification of sample rate conversion

A media synchronization method implemented by a computer, comprising:

• receiving a signal;
• determining a first sample rate of an external device;
• calculating a difference between a second sample rate of the computer and the first sample rate based on timing of communications between the computer and the external device and on the communications' delay time;
• determining a rate scalar based on the calculated difference;
• converting the received signal by applying the rate scalar;
• and
• outputting the converted signal such that the output signal is synchronized with an output of the external device.

A non-transitory computer-readable medium storing program instructions that, when executed, cause a processor to perform a method, the method comprising:

• receiving a signal;
• determining a first sample rate of an external device;
• calculating a difference between a second sample rate of the computer and the first sample rate based on timing of communications between the computer and the external device and on the communications' delay time;
• determining a rate scalar based on the calculated difference;
• converting the received signal by applying the rate scalar;
• and
• outputting the converted signal such that the output signal is synchronized with an output of the external device.
