SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. In its current version, SpectMorph ships with many ready-to-use instruments which can be combined using morphing.

SpectMorph is implemented in C++ and licensed under the GNU LGPL version 2.1 or later.

Audio Demos

"Night Flight" is a piece of music created by Sven Hinz and Stefan Westerfeld, which uses morphing between different musical instruments and custom samples integrated using the instrument editor. It was created under Linux, using Bitwig with the SpectMorph VST plugin (version 0.5.2). It is also available on YouTube.
