Description

Loudness metering tools excel in ensuring a proper balance among music, dialogue, and sound effects, accommodating both stereo formats and Atmos 7.1.2 surround sound systems. The management of long-form content becomes significantly more streamlined with the inclusion of a smart history overview feature. Users can effortlessly navigate through up to 10 hours of audio content using an interactive display, making it simple to access any part of a track. The custom alert system from BUTE efficiently highlights regions that fall outside user-defined parameters, as well as any True Peak overshoots, enhancing the user's ability to maintain audio quality. A variety of industry-standard presets are readily available to facilitate quick adjustments. In situations where screen real estate and CPU resources are limited, a compact read-out ensures optimal performance. Furthermore, BUTE's design is fully resizable, allowing for flexibility in how it fits into your workspace. Even in its compact view, users can seamlessly switch between various display settings and adjust limiting configurations, preserving valuable space for other applications. To achieve a smoother sound, users can fine-tune peaks by modifying pre-gain settings and selecting from preset release curves—Transparent, Natural, or Smooth—each crafted to minimize the audibility of gain reduction effectively. This versatility in settings and configurations makes it an invaluable tool for any audio professional.

Description

Audible's ACX outlines a total of eight technical standards, and any file that fails to meet even one of them is promptly rejected. Chapterpass meticulously prepares each chapter file to comply with these specifications, ensuring RMS loudness is maintained between -23 and -18 dBFS, peaks are capped at below -3 dBFS, the noise floor is under -60 dBFS RMS, and room tone is present at both the beginning and end, all while outputting a 192 kbps CBR MP3. Every file is reviewed for compliance with the complete specifications before it is made available for download, and users can see the actual measurements aligned with each requirement for all checkpoints. The processing is conducted within the user's browser via WebAssembly technology, guaranteeing that the audio files remain on the user's device throughout the process. There is no need to set up an account to use the service; the first file is complimentary, with subsequent charges of $36 per finished hour, $27 for five or more hours, and $18 for ten or more hours, all billed by the second. Additionally, a free measurement tool can be accessed at /free-acx-check, which evaluates the loudness, peak levels, noise floor, and silence padding against the specifications without conducting any mastering. Chapterpass is dedicated to mastering the necessary technical standards, although it does not perform any editing, noise removal, or corrections to narration. This ensures a streamlined process for creators looking to comply with ACX requirements efficiently.
