    About MULAW

    MULAW is a simple audio format for voice recordings, often used by phone systems. Choose it when you need clear speech in a compact file or when a device or app specifically asks for .mulaw files.

    • Great for speech: keeps voices clear and easy to understand.
    • Smaller file sizes than uncompressed audio, helping you save storage space.
    • Commonly used for call recordings, voicemail, and other phone-related audio.
    • Limited support on phones, browsers, and websites—convert to MP3 or WAV for easy sharing.
    • Works in many audio converters and editors, so you can open and save it without hassle.
    • Reliable for simple, general audio storage, especially for voice notes and call archives.
