Configure Auphonic RMS leveling preset

Step-by-step

1. Log in to Auphonic and click on Presets.
2. Click the New Preset button or select an existing one to edit.
3. Enter a name for the preset and input any desired metadata like title or author.
4. Set the output format to MP3 with a constant bit rate of at least 192 kbps.
5. Enable the Adaptive Leveler to ensure consistent audio peaks.
6. Under Loudness Normalization, set the Loudness Target to RMS and input -20dB.
7. Set the Peak Level to -3dB.
8. Adjust Noise Reduction (e.g., -3dB) and click Save.

Options

• Add intro and outro files via URL
• Add tags or extended metadata
• Split chapters automatically
• Toggle speech recognition or publishing to external services
• Enable filtering or reverb removal

Watch out for

• ACX requires files to be either all mono or all stereo; you cannot mix both in the same audiobook.
• ACX requires a bit rate of 192 kbps or higher.
• Do not use variable bit rate (VBR) for ACX; it must be constant bit rate.

Tips

• Use a free account to level up to two hours of audio per month.
• Leave the Adaptive Leveler on to bring high and low peaks closer together for consistency.
• Set noise reduction to -3dB even if your noise floor is already good to provide a slight cleanup.
