Sample Rate Conversion

Bridging the Gap in Multi-Device Audio Environments

Sample Rate Conversion (SRC) is a key component of digital audio processing that lets you change how many samples per second are used to represent a stream. It is fundamental when you need to make audio from one system work with another that uses a different sample rate. Getting SRC right is crucial in lots of audio applications, particularly in environments where multiple audio devices coexist, each potentially functioning with its own clock frequency.
The importance of SRC stems from three main factors: 1) preventing pitch distortion; in fact, running an audio stream at an incorrect rate can alter pitch or the relative relationships between pitches. 2) Maintaining synchronization, i.e., ensuring different devices remain in step with one another and 3) compensating for clock drift by accounting for slight frequency variations between devices nominally operating at the same frequency.

This presentation will begin with an introduction to the fundamental principles of SRC.

The goal for this talk is to give attendees a comprehensive understanding of SRC's importance in audio processing.
