Sample-Rate Conversion for Non-Clocked Audio Sources
Bill Whikehart · SAE International journal of passenger cars. Electronic and electrical systems · 2014
In a connected vehicle, digital audio content may arrive at the audio system from sources that provide packets of audio samples with no associated sample clock. A common example is streamed internet audio. To process and play these sources, the audio system must first convert the audio stream so that it is compatible with the system's sample clock. Traditional sample-rate conversion methods are typically not capable of doing this. This paper presents and compares approaches for performing the conversion.
