High-quality voice pitch shifting to change the perceived timbre and pitch of dialog and singing for creative and scrambling purposes.
TB VoicePitcher is a simple, while very effective plugin to change the overall pitch of dialog and vocals, including singing voices. Because its algorithms are specifically designed for the human voice, the results with TB VoicePitcher will typically sound better, cleaner, and more natural than with other general-purpose pitch shifting algorithms*. Pitch shifting can be performed in real time, with a small latency that is compensated for by the DAW host (if supported). Furthermore, spectral (formant) corrections to improve the timbre of pitched vocals can be applied as well.
*Because TB VoicePitcher is specifically designed to process the human voice, it is less suitable for other content such as polyphonic music or rhythm tracks.
Below is a comparison to stock DAW vocal pitch shifters. We took a short vocal clip and pitched it up by no less than 7 semitones. First up is the Logic Pro X stock Pitch Shifter, set to ‘vocals’ mode. Note the instabilities and artifacts during the sustained parts of individual notes:
The next example was done with Logic Pro X’s vocal transformer plugin. Here, the sustained parts of the vocals are clearly better than with Logic Pro X Pitch Shifter, but the sibilant sounds come out rough, and there are several artifacts during pitch transitions (note the significant ‘blip’ near the end!). Moreover, the timbre is quite unnatural:
The result of TB VoicePitcher is given below. Note how the vocals come out smoothly without artifacts, and with a more natural timbre compared to the previous examples:
- Real-time, high-quality vocal pitch processing
- Mono and stereo operation modes
- Ability to mix input and output for creative effects / vocal doubling
- Spectral formant correction
- Pitch range from -12 to +12 semitones
- Adjustable threshold for automatic disabling of processing
