https://audio.dev/ -- @audiodevcon​ --- SRC - Sample Rate Converters in Digital Audio Processing - Theory and Practice - Christian Gilli & Michele Mirabella - ADC 2024 --- 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. --- Slides: https://data.audio.dev/talks/2024/sam... --- Christian Gilli I'm a software engineer with 6+ years of experience working on high-performance implementations of DSP algorithms for audio applications in C++. Right now, I spend most of my time working on writing high-performance numerical software for DSP applications on heterogeneous platforms. --- Michele Mirabella Michele Mirabella received the B.S. degree (cum laude) in electronic engineering from the University of Modena and Reggio Emilia, Italy, in 2019, and the M.S. degree (cum laude) in electronic engineering from the University of Bologna in 2021. He is currently pursuing the Ph.D. degree with the University of Modena and Reggio Emilia, Italy. His main research interests lie in the area of joint communication and sensing systems. --- ADC is an annual event celebrating all audio development technologies, from music applications and game audio to audio processing and embedded systems. ADC’s mission is to help attendees acquire and develop new audio development skills, and build a network that will support their audio developer career.
