How to achieve natural sounding pitch correction

Question

How do I achieve natural sounding pitch correction?

Answer

The goal of pitch correction is to take a vocal line that has pitch problems, run it through the pitch corrector, and have it sound like it was sung without pitch problems. Combined with extremely effective pitch detection algorithms, the three parameters described above give TC Helicon products with pitch correction the control to achieve this goal better than other products in the industry.

To get optimal results with pitch correction you need to use these parameters differently for different circumstances.

Correcting Recorded Material

Using pitch correction on recorded material allows you to really “tweek” parameters to get the optimal results. The highest quality results are attained with the LEAD DELAY COMPENSATION parameter in the setup menu set to On, however you will need to re-timealign the vocal track to compensate for the delay.

Slow Ballads

  1. In the Pitch Correction menu, set the appropriate ROOT and SCALE TYPE for thesong you are working with.
  2. Set the WN and AM parameters to maximum (200 and 99 respectively)
  3. While listening to the vocal line adjust the AT parameter starting at 0 and turn it up until the vocal sounds in pitch. Remember, the lower the Attack value the more natural the sound, the higher the Attack value, the “harder” the correction applied.

Fast Songs

Natural sounding automatic pitch correction of fast songs is typically a challenge with automatic pitch correction products from other companies since they only offer controls similar to the Attack parameter in the VoiceWorks. The problem is that when correcting faster songs, the attack settings must be set quite high for correction to occur. High attack settings result in the pitch jumping directly from one note to another making the note transitions soundunnatural. The Window parameter allows setting the VoiceWorks so that note transitions are not altered.

  1. Follow the same procedure as with slow ballads. Chances are that the AT setting required to make the vocals sound in tune will also result in the vocal sounding somewhat artificial. To reduce this artificial sound, continue with the following steps.
  2. Turn down the WN parameter until note transitions sound natural, but pitch errors are still being corrected. A WN value that is too low will result in some pitch errors not being corrected, too high and the note transitions sound robotic.
  3. If the correction still sounds artificial, try turning down the AM parameter.

That synthy vocoder sound

You know, the one the industry refers to as the “Cher effect”.

  1. In the Pitch Correction menu, set the appropriate ROOT and SCALE TYPE for the song you are working with.
  2. Set WN, AT and AM to their maximum values.
