| dc.description.abstract | Audio time stretching and pitch shifting are operations that all major commercial and/or open source Digital Audio Workstations, DJ Mixing Software and Live Coding Suites offer. These operations allow users to change the duration of audio files while maintaining the pitch and vice-versa. Such operations enable DJs to speed up or slow down songs in order to mix them by aligning the beats. Unfortunately, there are few (and experimental) client-side JavaScript implementations of these two operations. In this paper, we review the current state of the art for client-side implementations of time stretching and pitch shifting, their limitations, and describe new implementations for two well-known algorithms: (1) Phase Vocoder with Identity Phase Lock and (2) a modified version of Overlap & Add. Additionally, we discuss some issues related to the Web Audio API (WAA) and frequency-based audio processing regarding latency and audio quality in pitch shifting and time stretching towards raising awareness about possible changes in the WAA. | en_US |
