Here are some sounds that I created while exploring the topic of imposing the tonality or harmonics of one sound on another in the Image Filter room. This sort of manipulation is both easy to perform and can result in an almost endless variety of sounds -- depending on the sources used, the filter picture created, and the tuning of the Image Filter canvas. I will write up notes about how these were done IF (and only IF) I hear from people that they would like to know how these were done. Please rate the items and participate in the poll, it only takes a few seconds. Your participation really helps provide the resources that is most beneficial.
Please be patient as the examples load. Some machines may stutter during playback if sounds are still loading.
Here are the source sounds that were processed. There are a couple of additional sounds that were used to derive the filters (via analysis to picture) but they are samples of commercial artists and I don't feel that it would be right for me to post them.
VOCAL PRESET: Unprocessed Image Synth Preset that makes use of a vocal multisampler
DRUM LOOP: Unprocessed Image Synth Preset that uses a drum multisampler instrument.
GUITAR HARMONIC: Recording of a plucked guitar harmonic. Simple sounds like this make great sources for creating Image Filters and for re-synthesizing in the Spectrum Synth.
Here are the results of treating the sources with filters derived from other sounds. These all apply the filters to long sounds. They can also be applied to short sounds to create nice sweep effects. Let me know if you want more examples or want to know how these were created.
All of the filters that were used in these examples were derived from sounds that were loaded into MetaSynth's sample editor and analyzed to the Image Synth or Image Filter canvas by applying the the Analyze Spectrum menu command. Such filters will impart some of the characteristics of the sound from which they were derived. In example FH02, the filter's envelope is hardly recognizable because it is being stretched over a much longer duration than than the source sound's.
For some (rough) notes/tips/thoughts on the Spectrum Synth resynthesis used in FH01 and FH02 click here.
FH01: Filtered Harmonic Spectrum Sequence. To create this sound the guitar harmonic had an Image Filter applied to it and then the resulting sound was analyzed and resynthesized in the filter synth across a much longer duration than the original sample. The Image Filter for this example was derived from a pad sound at the beginning of Autechre's Kalpol.
FH02: Filtered Harmonic 2. This sound was created by a process similar to the one used to create the first example. In this case, the Image Filter for this example was derived from a filter swept note near the beginning of Autechre's Kalpol.
