What is PCM format?

PCM (Pulse-Code Modulation) is a standard method for digitally representing analog audio signals. It's the raw, uncompressed audio format used in CDs, DVDs, and professional audio equipment.

What audio formats can I convert to PCM?

You can convert WAV, MP3, FLAC, AAC, OGG, M4A, and most common audio formats. The tool uses the Web Audio API to decode these formats before converting to PCM.

Does this tool upload my files to a server?

No, all audio processing happens entirely in your browser using JavaScript. Your files never leave your computer, ensuring complete privacy.

What's the difference between PCM WAV and PCM RAW?

PCM WAV saves the PCM data in a standard WAV container with headers, which is playable by most media players. PCM RAW saves only the raw PCM data without headers, which is useful for programming and embedded systems.

What are the maximum file size and duration limits?

The tool can process files up to 100MB in size or 30 minutes in duration. Larger files may cause browser memory issues.
