Real Instrument Samples
Every sample below was processed by the Sieve prototype algorithm. These are not synthesized demos. They are real recordings: guitars, vocals, and isolated instrument tracks run through spectral harmonic masking.
Select 0.0 for the unprocessed dry signal, then click any pedal position to hear the effect applied. Switching positions while playing picks up at the same point in the song, so you can hear the filter change in real time.
Guitar and Voice
Raw recordings made specifically for Sieve testing.

VoiceIsolated Guitar Tracks
Guitar stems isolated from studio and live recordings. These tracks showcase how Sieve handles real electric guitar with distortion, feedback, and expressive playing.

Electric GuitarVocal Tracks
Sieve on the human voice. Vocal harmonics are rich and complex, making them an excellent test of the algorithm's pitch tracking and masking precision.

VoiceDual-Bus Processing
These samples use the dual-bus architecture: harmonics and fundamental separated, processed independently through different pedal positions, then recombined. The notation "01/09" means fundamental bus at pedal 0.1 and harmonic bus at pedal 0.9.
