Is strict audiobook submission guidelines causing you headaches? Spending way too much time in your DAW manually clipping silence, aligning loudness levels, and repairing background noise?
Convert Pro is your all-in-one batch audio post-processing solution. We focus on solving the delivery pain points for independent audiobook narrators, voice actors, and podcast teams, helping you turn raw audio recordings into completely compliant, studio-quality master files in seconds.
【Core Features & Advanced Audio Processing】
One-Click ACX Audiobook Compliance Instantly master your recordings to meet the strict technical standards of Audiobook Creation Exchange (ACX). The app formats your output to 192kbps CBR, 44.1kHz, and Mono, automatically handling target loudness normalization (-20 LUFS), brickwall peak limiting, noise reduction, and room tone balance for 100% acceptance.
Smart Silence Trimming & Natural Room Tone Restoration
Precision Silence Trim: Automatically detects and trims excessive leading and trailing silence based on your custom decibel threshold (dB) and minimum duration (s), giving your files a clean, professional start and end.
Room Tone Repair: Platforms like ACX forbid absolute digital silence at boundaries. Convert Pro’s advanced DSP engine automatically extracts natural ambient noise from the source audio and fills the trimmed boundary gap with seamless fade-ins and fade-outs, preserving acoustic consistency.
Professional Loudness Normalization Matrix Equipped with industrial-grade algorithms and presets for multiple target platforms:
Audiobook ACX Standard (-20 LUFS)
Podcast Standard (-16 LUFS)
Music Streaming Standard (-14 LUFS)
Broadcast Standard (-23 LUFS)
Custom Mode: Total control to adjust Target Loudness (LUFS), True Peak limit (dB), and Loudness Range (LRA / LU).
Fine-Grained Audio Tweaking & Delivery Verification Apply millisecond-level fade-ins and fade-outs to avoid popping sounds, adjust high-fidelity volume gain (dB), convert channels (Mono/Stereo), and automatically verify audio format structures to ensure zero defects after processing.
【Designed for macOS & Professional Workflows】
Apple Silicon Native Performance: Optimized for M1/M2/M3 series chips to leverage multicore architecture for blazing-fast concurrent batch processing.
Tag In-Place Direct & Fast I/O: Direct metadata tag writing without file duplication. This reduces physical disk I/O by 50% on macOS, avoiding app freezes when dealing with large high-fidelity files on external drives.
Native CLI & Automator Integration: Support for headless Terminal execution. You can easily integrate Convert Pro into macOS Shortcuts, Automator, or custom shell scripts for an automated production pipeline.
Elegant macOS Aesthetics: Fully supports System Dark Mode with a premium Morandi teal visual design, making long hours of editing easy on the eyes.
