App para obter informações de arquivos de áudio como o que mkvinfo faz para arquivos mkv

Question

Alguém sabe de um aplicativo que pode obter as informações do arquivo de um arquivo como arquivos flac e wav? Um aplicativo como o mkvinfo, mas para arquivos de áudio para arquivos flac e wav?

Obrigado

Um exemplo é abaixo do que o mkvinfo mostra quando você escolhe um arquivo mkv
