FAQ - PCM Encoder

What is PCM and WAV audio encoding?

PCM (Pulse Code Modulation) is uncompressed, raw digital audio data. WAV (Waveform Audio File Format) is a container that stores PCM audio. PCM/WAV provides the highest possible quality with no compression artifacts, ideal for professional audio production and archiving.

How do I encode audio to WAV/PCM online for free?

Upload your audio file (MP3, FLAC, OGG, AAC, or other formats) to our free PCM encoder. Select your sample rate and bit depth, then download your uncompressed WAV file. All encoding happens in your browser – no upload required.

What sample rate and bit depth should I use?

For CD quality, use 44.1 kHz / 16-bit. For professional audio production, use 48 kHz / 24-bit or higher. For video work, 48 kHz is standard. Higher sample rates (96 kHz, 192 kHz) are used in professional studios but offer diminishing returns for most listeners.

Is WAV better than FLAC?

WAV and FLAC decoded are identical in quality – both are lossless. WAV is uncompressed (larger files) with maximum compatibility. FLAC is compressed (smaller files) with excellent modern support. Use WAV for professional DAWs, FLAC for storage and playback.

Is the PCM encoder free to use?

Yes, our PCM/WAV encoder is 100% free with no limitations. Encode unlimited audio files to uncompressed WAV format without registration or hidden costs. The tool runs entirely in your browser.

Are my files uploaded when encoding to WAV?

No! All PCM encoding happens 100% locally in your browser using WebAssembly technology. Your audio files never leave your device – complete privacy guaranteed. The encoding runs directly on your computer.

Why are WAV files so large?

WAV files are uncompressed – every audio sample is stored in full. A 3-minute song at CD quality (44.1 kHz/16-bit stereo) is about 30MB. Higher sample rates and bit depths increase file size proportionally. Use FLAC for lossless compression if size matters.

When should I use PCM/WAV format?

Use PCM/WAV for professional audio editing, music production, video soundtracks, broadcasting, archival masters, and any situation requiring maximum quality and compatibility. WAV is the standard format for professional audio workstations and editing software.
