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 3.

Audio Demos

"Morphing Motion" is a piece of music created by Sven Hinz and Stefan Westerfeld, which uses morphing between different musical instruments to create a variety of interesting sounds. It was created under Linux, using Bitwig 2 with the SpectMorph VST plugin (version 0.3.2).

Integrating SpectMorph into your Work

In order to make music that contains SpectMorph, you currently need to use Linux. There are four ways of integrating SpectMorph sounds into music you create:

LV2 plugin - preferred for all sequencers that support LV2
VST plugin - especially for proprietary solutions that don't support LV2
BEAST plugin - for advanced usage patterns using the modular environment provided by BEAST
JACK standalone - application using JACK for midi input and audio output

Note that at this point, we may still change the way sound synthesis works, so newer versions of SpectMorph may sound (slightly) different than the current version.
