Convert MPEG to WAV — Free Online Converter

WAV (Waveform Audio File Format), co-developed by Microsoft and IBM in 1991, is the standard uncompressed audio format for Windows and the most widely supported lossless audio format across all platforms. MPEG files contain audio as MPEG Audio Layer 2 at bitrates typically between 128 and 384 kbps. Converting MPEG to WAV extracts and decodes this audio into raw PCM data — the universal starting point for audio editing, processing, and mastering.

WAV is the lingua franca of audio production. Every DAW (Audacity, Pro Tools, Ableton, FL Studio, Reaper), every audio plugin, every sound card, and every operating system handles WAV without conversion or codec negotiation. When you extract audio from MPEG for editing purposes, WAV eliminates all compatibility variables.

WAV is also essential for applications that require sample-accurate audio: forensic analysis, scientific measurement, broadcast automation, and CD mastering. The format's simplicity — just a RIFF header followed by raw PCM samples — means there are zero decoding artifacts, zero codec dependencies, and zero compatibility issues. If the audio needs further processing, WAV is where you start.

FFmpeg decodes the MP2 audio and writes raw PCM to a WAV container: `-vn -acodec pcm_s16le -ar 44100 -ac 2`. WAV uses little-endian byte order (unlike AIFF's big-endian). For 24-bit output: `pcm_s24le`. For 32-bit float (used in some DAWs): `pcm_f32le`. The WAV format has a 4 GB file size limit in its standard RIFF implementation; use RF64 (W64) for files exceeding this.
