Auphonic Leveler Batch Processor Overview
The Auphonic Leveler is an advanced Desktop Batch Audio File Processor designed to analyze and optimize audio files to achieve balanced and consistent loudness. Here’s a detailed look at what the product does and its key features.
Primary Function
The Auphonic Leveler is an intelligent audio processing tool that corrects level differences within audio files. It analyzes the content of the audio and adjusts the loudness to ensure consistency between speakers, music, and speech segments. This makes it particularly useful for applications such as podcasts, radio broadcasts, lectures, conference recordings, and video productions where maintaining a balanced audio level is crucial.
Key Features
Adaptive Leveler
The Adaptive Leveler uses machine learning techniques to classify different segments within an audio file, such as music, speech, and background noise. It then adjusts the loudness of these segments to achieve a balanced overall loudness. This feature ensures that music segments retain their natural dynamics while speech segments are normalized to a consistent level.
True Peak Limiter
The Auphonic Leveler includes a True Peak Limiter, which prevents audio from exceeding specified loudness standards. This is essential for compliance with various loudness standards such as EBU R128, ATSC A/85, and those for podcasts and mobile devices.
Noise and Hum Reduction
The software features automatic noise and hum reduction algorithms, which help in cleaning up the audio by removing unwanted background noises like wind, breathing, or electrical hum.
High Pass Filter
An adaptive High Pass Filter is included to cut unnecessary and disturbing low frequencies, depending on the context of the audio (speech, music, or noise).
Loudness Normalization
The Auphonic Leveler targets common loudness standards, ensuring that the final audio output meets the required specifications for different platforms and devices.
Advanced Leveler Modes
The Leveler can operate in three different modes: Default Mode, Separate Music/Speech Parameters, and Broadcast Mode. These modes allow for detailed control over Leveler Strength and the use of Broadcast Parameters such as Maximum Loudness Range (MaxLRA), Maximum Short-term Loudness, and Maximum Momentary Loudness.
Parallel Processing and Presets
The software supports parallel processing of multiple files, allowing users to drag and drop audio collections into the program window for simultaneous processing. Users can also save their current settings as presets, including audio algorithm parameters, output file options, and hardware settings.
Additional Information
- Compatibility: It is important to note that the Auphonic Leveler does not work on macOS versions newer than Ventura. Users are advised to consider using the Auphonic web service instead, as new algorithms require custom hardware that cannot be integrated into the current desktop apps.
- User Interface: The application provides detailed audio statistics and a user-friendly interface for managing and monitoring the processing of multiple files.
The Auphonic Leveler is a powerful tool for audio professionals and content creators who need to ensure their audio files meet high standards of quality and consistency.
