Introduction to De-Clicking and Mouth Noise Removal

As a voice actor, you know how important it is to deliver high-quality audio that meets ACX requirements. De-clicking and mouth noise removal are two essential steps in achieving professional-sounding audio. De-clicking involves removing unwanted clicks and pops from your recording, while mouth noise removal eliminates distracting sounds like lip smacks and tongue clicks. To directly answer your search query, de-clicking and mouth noise removal can be achieved using specialized audio editing tools like iZotope RX 10 and FabFilter Pro, which can help you meet the ACX audio requirements of -24 LUFS and -3 dB peak level.

Understanding ACX Audio Requirements

ACX has specific audio requirements that voice actors must meet to ensure their audiobooks are of high quality. These requirements include a loudness level of -24 LUFS and a peak level of -3 dB. To achieve these levels, voice actors must use audio editing tools to remove unwanted sounds and normalize their audio.

Technical Details for De-Clicking and Mouth Noise Removal

When it comes to de-clicking and mouth noise removal, there are several technical details to consider. For example, the threshold level for de-clicking can be set between -30 dB and -50 dB, depending on the type of click and the overall loudness of the audio. Mouth noise removal, on the other hand, can be achieved using a combination of EQ and compression techniques. Some popular tools for de-clicking and mouth noise removal include:

  • iZotope RX 10
  • FabFilter Pro
  • Adobe Audition
