Building upon the foundation of the original ALM 5.1 plugin, this standalone application enhances audio loudness and true peak metering with expanded capabilities and greater flexibility. Designed to handle complex audio environments, it supports mono, stereo, and 5.1 channel formats, providing comprehensive loudness measurements that cater to professional standards. The interface allows users to monitor Momentary, Short Term, and Integrated Loudness levels, along with Loudness Range and maximum True Peak levels, ensuring precise control over audio dynamics.

Fully compliant with key loudness standards such as BS-1770 (rev.3), EBU R128, and ATSC A/85, this tool delivers real-time metering with accurate peak hold functionality. It calculates Max True Peak levels by detecting inter-sample peaks that might be missed during quantization, maintaining high fidelity in loudness measurement. The application supports various sample rates commonly used in audio production and features color-coded loudness descriptors to help users easily identify comfort zones. Thresholds for True Peak and Short Term Loudness are adjustable to fit different monitoring needs.

Optimized for low CPU usage, this metering solution offers efficient performance on both Windows and Mac systems. It stores detailed measurement data in XML format for flexible review and documentation. Additionally, remote monitoring is supported through an accompanying iPad application, allowing users to track loudness levels away from their main workstation. This combination of precision, adaptability, and ease of use makes it a reliable choice for audio professionals seeking detailed loudness management.
