本文介绍了斯坦福大学钢琴卷档案馆（SUPRA）收藏的大量历史钢琴卷录音的数字化过程，这一过程产生了一个最初的数据集，其中包括从世纪早期转录到CD格式的478场钢琴演奏。该过程包括扫描纸卷，数字化打孔器，并将气动表达编码转换为可转换格式，以创建表现力表现文件。我们提供此过程每个步骤的衍生文件，包括轧辊的高分辨率图像，孔数据的“原始”文件，将孔数据转换为动态的“表达性”文件，以及数字钢琴样品上表达性文件的音频文件渲染。这为研究人员提供了一个灵活的、可搜索的在线数据库中的卷的数字访问。我们目前提供的初始数据集“SUPRA-RW”来自SUPRA中精选的“红色Welte”型辊。该数据集提供了重要的历史钢琴演奏的滚动扫描和重传，其中许多是第一次广泛使用。
This paper describes the digitization process of a large collection of historical piano roll recordings held in the Stanford University Piano Roll Archive (SUPRA), which has resulted in an initial dataset of 478 performances of pi-anists from the early twentieth century transcribed to MIDI format. The process includes scanning paper rolls, digitizing the hole punches, and translating the pneumatic expression codings into MIDI format to create expressive performance files. We offer derivative files from each step of this process, including a high resolution image of the roll, a “raw” MIDI file of hole data, an “expressive” MIDI file that translates hole data into dynamics, and an audio file rendering of the expressive MIDI file on a digital piano sample. This provides digital access to the rolls for researchers in a flexible, searchable online database. We currently offer an initial dataset, “SUPRA-RW” from a selection of “red Welte”-type rolls in the SUPRA. This dataset provides roll scans and MIDI transcriptions of important historical piano performances, many being made available widely for the first time.
