Download Making Sounds with Numbers: A Tutorial on Music Software Dedicated to Digital Audio A (partial) taxonomy of software applications devoted to sounds is presented. For each category of software applications, an abstract model is proposed and actual implementations are evaluated with respect to this model.
Download Fractionally-addressed Delay Lines While traditional implementations of digital delay lines are based on a circular buffer accessed by two pointers, we propose an implementation where a single fractional pointer is used both for reading and writing operations. On modern general-purpose architectures, the proposed method is nearly as efficient as the popular interpolated circular buffer, but it offers better performance in terms of frequency-dependent attenuation and response to delay-length modulations.
