Introduction

The escalating ACX Audiobook Editing business makes it possible for both authors and narrators to connect with larger readerships. Great audiobooks originate from skilled editing processes responsible for their achievement. Publisher platforms like ACX (Audiobook Creation Exchange) need editing for your audiobook and it is mandatory for submission. Why? ACX enforces specific technical standards that become essential for the success of your audiobook because listeners tend to judge your audiobook through their hearing experience.

You will discover every essential aspect of ACX audiobook editing through our complete guide as we explain how to meet ACX requirements and perfect your audio files for expert-level casualty.

Understanding ACX Requirements

Overview of ACX’s Technical Requirements

All the vendors need to produce scapes that follow the technical requirements from ACX for standardized audio delivery. Here’s a quick breakdown:

• File Format: All remaining files must exist in MP3 format at 192 kbps bitrate, and must be free of any integrity corruption.

• RMS Levels: Between -23 dB and -18 dB.

• Noise Floor: No higher than -60 dB.

• Peak Levels: No peaks above -3 dB.

• Spacing: To maintain proper record chain integrity, beginning and ending require separate recordings of silence spanning 0.5 to 1 second followed by 1-5 seconds of room tone.

Quality Control Standards for Submission

All submitted files are fully reviewed by ACX team members to ensure compliance with standards. If your work violates ACX’s technical standards at submission time, it will take longer for it to be published. Combining editing with mastering means that such a quality meets all of the appropriate quality requirements.

Pre-Editing Preparation

Recording Best Practices

When you begin typing on your computer system preparation for editing requires proper recording practices. Use these tips to minimize editing needs:

• You should choose a calm indoor space that works to block out environmental sounds during your recording session.

• The choice between using a condenser microphone paired with a dedicated pop filter determines the quality of your recording experience.

• Your standard audio patterns depend on a consistent setup of your microphone devices.

An Ideal Environment for Recording Needs Proper Arrangement

The recording space must contain no echoes while removing both background noises and possible interruptions. To enhance your professional setup you need acoustic foam and both rigid microphone stands and proper illumination systems to improve environment quality.

Narrator Tips for Easier Editing

Maintaining Consistent Tone and Pacing

The editing process becomes extremely hard when storytelling lacks good internal consistency. Narrators should:

• Senior editors need to avoid recommending instructions that play at either extremely fast or extremely slow paces.
• All vocal sessions demand continuous energy stability from beginning to end.
• The successful start of your recording session happens after warm vocalization prevents fatigue which ensures proper session completion.

Reducing Mouth Clicks and Background Noise

Drinking sufficient water before your recording period helps decrease mouth sounds during your recordings. A noise gate will serve as your vital tool for making clear unambiguous voice recordings while eliminating background noise in the recording area.

The Editing Process

Steps to Clean Raw Audio

Raw audio can be messy. Follow these basic steps:

• SoftWareTool reveals a dialog that prompts you to insert the selected audio file. By doing so your DAW software application will begin handling the contents within the file.

• The reduction of ambient noise in your audio signals requires specialized editing tools known as noise reduction tools.

• Trim unnecessary pauses or mistakes.

Noise Reduction Techniques

Background noises vanish when users apply noise reduction tools found in iZotope RX or within Audacity’s built-in functionality. Test audio settings by keeping an eye out to avoid modifications in your voice quality.

Removing Pops, Clicks, and Plosives

Documented vocal noises known as plosives (such as “p” sounds) create disturbances that affect your listener’s experience negatively. When capturing audio install a pop filter and use DeClicker editing tools with other remedies to minimize distracting noises.
