О мета-тегах и постобработке:

LameXP обеспечивает полную поддержку для мета-информации, включая обложку. Поэтому при преобразовании аудио файлов, любая существующая мета-информация будет сохранена в максимально возможной степени. Есть простой в использовании мета-тег редактор, для добавления новой мета информации или редактирования имеющейся. LameXP обеспечивает полную поддержку Unicode в мета-информации и именах файлов. Благодаря нашим переводчикам, интерфейс LameXP доступен на многих языках. Последнее, но не менее важное, LameXP поддерживает пост-обработку, включая преобразование частоты дискретизации, нормализация (регулировка усиления), регулировка тона, а также down-mixing.
