Convert M4P to WAV — Free Online Converter

M4P is Apple's compressed DRM-protected audio format using AAC encoding at 128-256 kbps, while WAV (Waveform Audio File Format) is the uncompressed audio standard co-developed by Microsoft and IBM. Converting M4P to WAV decodes the AAC audio and writes it as raw PCM samples in the RIFF WAV container — the most universally compatible uncompressed audio format in existence.

WAV is the common denominator of digital audio. Every operating system, audio editor, DAW, hardware player, and programming library supports WAV natively. If you need your old iTunes audio in the most universally compatible uncompressed format possible, WAV is the definitive choice.

WAV is the standard input format for professional audio tools across all platforms. Pro Tools, Ableton Live, FL Studio, Audacity, Logic Pro, and virtually every other DAW handles WAV with zero import friction. If you need to bring old iTunes purchases into a production environment for editing, mixing, or processing, WAV ensures compatibility regardless of what platform or software you use.

WAV is also the safest format for audio processing pipelines. Any tool that reads audio can read WAV — there are no codec licensing issues, no decoding quirks, and no compatibility surprises. For CD burning, WAV is the native format (Red Book CD uses 16-bit 44.1 kHz PCM, which is exactly what WAV stores). Converting M4P to WAV prepares your audio for any downstream use without format-related obstacles.
