Pitch correction for audio

Sometimes you might be working with a recording that’s out of tune. Perhaps it’s an older recording, or it uses a pitch standard other than A440, or the musicians simply didn’t tune their instruments.

For these situations, Soundslice supports pitch correction (aka pitch shifting). You can make fine-grained tweaks to your recording’s tuning, and you can save these tweaks so that they’ll automatically be applied to anybody viewing your slice.

Prerequisites for pitch correction

Pitch correction is only supported for MP3 recordings — either uploaded directly to Soundslice or via MP3 URL. And it’s only supported if you have enhanced slowdown activated.

Setting the default pitch correction for a recording

To set the default pitch correction for a recording, open the syncpoint editor. You should see controls for Semitones and Cents above the waveform:


If you don’t see the Semitones and Cents controls, make sure you’re editing an MP3 (as opposed to a video), and make sure you have enhanced slowdown enabled.


You can use those two controls to change the audio’s pitch. Use the plus and minus icons to increase or decrease the values. A cent is 1/100th (one onehundredth) of a semitone.

These controls work during playback, so you can hear immediate feedback as you change the values. We suggest creating a loop by dragging over a small area of the waveform, so that you hear the same section for easy evaluation as you shift the pitch.

After you’ve found the right pitch correction, just hit the Save button at upper right. From then on, anybody viewing this recording in your slice will have the pitch correction applied (assuming they have enhanced slowdown enabled).

What happens if somebody viewing my slice hasn’t enabled enhanced slowdown?

In this case, the audio won’t be pitch-corrected. The person will hear the original, unprocessed audio.
