TAPIIR, A Software Multitap
The use of delays is one of the oldest techniques for effects processing and electro-acoustic composition. Originally, tape-loops were used to create effects of echo and reverb. Nowadays, most hardware effect processors provide digital implementations. These have a clearly superior soundquality compared to tape-delays, but also imply some restrictions. Delay-length is limited by the internal memory, and delay time accuracy is often sacrificed for computational efficiency or even deliberately restricted for user-interfacing. This paper presents a dedicated software implementation of a flexible multi-delay, that aims to combine flexibility and high accuracy with high quality audio and usability. At the same time, several important issues in software effect processing will be addressed.
