Frenquently Asked Questions
What does Time-Pitch Control actually do?
It lets you change the pitch and/or speed of an audio track independently, without degrading the sound quality.
What are the adjustment limits?
You can shift pitch by -12 to +12 semitones, and adjust speed from x0.1 to x10.
Will changing speed affect pitch, or vice versa?
No. You can speed up or slow down without altering pitch or transpose pitch without changing tempo.
Does the audio lose quality at extreme settings?
Not with our model. You get artifact-free results, even with drastic changes, thanks to IRCAM’s signal processing algorithms.
What kind of audio is it best for?
Ideal for music editing, language learning, podcasting, video syncing, and more wherever timing or pitch needs adjusting.
