The Transpose feature in SoundID VoiceAI allows you to alter the pitch of the generated audio. This function is available across all Voice and Creative (instrument) presets.

Transpose
The primary use case for SoundID VoiceAI is transforming a singing voice into a realistic singing voice of another human being. Ideally, the original input should match the best input pitch - see the preset descriptions for what recorded audio pitch will generate the best results. If the natural vocal range difference is significant between the input audio and the applied preset, pitch adjustments can be made with the Transpose feature.
Transpose allows pitch adjustments by semitones (half steps) for the generated audio. 12 steps of the Transpose parameter value corresponds to an octave. Transpose can be adjusted to +/- 4 octaves (48 steps up or down). If the Transpose value is unaltered, the pitch will remain the same.
Achieving optimal results becomes more straightforward and efficient when certain parameters are considered, particularly when a project is fixed to a specific key. Before processing a vocal track, we recommend taking the following steps:
- Preview the preset by clicking on "▶" (play button).
- Evaluate the best input pitch to find a suitable preset without Transposing the output pitch.
- Use Transpose according to the preset model's vocal range:
- If the target preset sings in a higher pitch than your input voice track, increase the value of the Transpose parameter.
- If the target preset sings in a lower pitch than your input voice track, decrease the value of the Transpose parameter.
- Process a small section and evaluate the results before committing to process the entire track.
Note: Transpose values below or above 12 might produce unexpected results. Using Transpose with Drums will have a small impact on the overall sound and is not advised.
Auto-transpose
By default, an additional Auto-transpose feature is enabled. When it is active, the Transpose knob is unavailable for adjustments, and the plugin automatically detects and applies the optimal Transpose value for the combination of the captured audio and the applied preset.
- For Voice presets, the auto-transpose values can be -12, 0, or +12
- For Creative (instrument) presets, the auto-transpose values range from -24, -12, 0, +12, or +24
To switch back to manual Transpose adjustments, disable the 'Auto' checkbox - manual adjustments will become available again (by default, the last set value of Auto-transpose will be retained).
