WAV (Waveform Audio File Format) is the foundational uncompressed audio format developed by Microsoft and IBM in 1991. Storing raw PCM audio data with zero compression, WAV is the standard working format for audio editing, mastering, and professional production. RM (RealMedia) files from the late 1990s contain audio encoded with RealNetworks' proprietary codecs at extremely low bitrates — typically 32-96 kbps — designed to stream through RealPlayer over 56 kbps dial-up connections.
Converting RM to WAV decodes the compressed RealAudio stream and stores every sample as uncompressed PCM data. This creates the most edit-friendly possible representation of the RM audio, suitable for restoration, processing, and professional audio workflows.
Uncompressed WAV is the universal working format for audio production. Every DAW (Digital Audio Workstation), audio editor, and professional tool works natively with WAV. RM files cannot be imported into any modern audio software — Audacity, Adobe Audition, Pro Tools, and Reaper cannot read RealAudio streams. Converting to WAV creates a universally importable file.
WAV is also the safest intermediate format when the final output format is not yet decided. Extracting RM audio to WAV first, then converting to any target format later, avoids lossy-to-lossy transcoding. The uncompressed PCM in WAV serves as the highest-fidelity master available from the RM source.
FFmpeg demuxes the RM container and decodes the RealAudio stream (Cook, ACELP, or other legacy codecs) to raw PCM samples. These are written to a WAV file as uncompressed linear PCM. Default output is 16-bit at the source sample rate (often 22.05 kHz or 44.1 kHz), mono or stereo matching the source. The RIFF/WAV header contains format metadata including sample rate, bit depth, and channel count.
WAV output preserves exactly the quality of the decoded RM audio — every PCM sample from the RealAudio decoder is stored without modification. No additional quality loss occurs. However, the quality ceiling is set by the original RealAudio encoding: 32-96 kbps lossy compression with limited frequency response. The WAV file faithfully represents this low-quality audio as uncompressed PCM. Audio restoration tools can potentially improve perceived quality, but the raw conversion cannot add information that was lost in the original encoding.

RM to WAV conversion produces the highest-fidelity, most universally compatible representation of RM audio content. Uncompressed PCM in WAV serves as the ideal master for editing, restoration, and future format conversion from legacy RealAudio sources.
