Using dynamic time warping to improve the classical music production workflow
… collaborated with the Boston Symphony Orchestra (BSO) sound engineers to gather requirements for this work, which led to the identification of our two tools: an automatic marking transfer (AMT) system and an audio search (AS) system. We then collaborated with other potential users for both AMT and …
