RM (RealMedia) was the dominant streaming format of the early internet, developed by RealNetworks in 1997 when buffering a 30-second clip over a 56 kbps modem was considered impressive technology. RM files encode audio using RealAudio codecs (Cook, ACELP) at bitrates as low as 16 kbps, sacrificing fidelity for reliable modem delivery. AIFF (Audio Interchange File Format) is Apple's uncompressed audio container, storing PCM data at CD quality or higher — the standard working format for professional audio production on macOS.
Converting RM to AIFF decodes the compressed RealAudio stream and stores every sample as uncompressed PCM. While this cannot restore quality lost during the original RealAudio encoding, it produces an edit-friendly file that professional audio tools handle natively without re-decoding overhead.
Professional audio editing requires uncompressed formats. DAWs like Logic Pro, Pro Tools, and GarageBand work most efficiently with AIFF or WAV, applying effects and processing without repeated lossy decode-encode cycles. If you need to clean up, restore, or incorporate RM audio into a production project, AIFF is the correct intermediate format.
RM files are also completely unreadable by modern audio software. Neither Logic Pro nor Pro Tools can import RM files directly. Converting to AIFF creates a universally compatible professional audio file from an otherwise inaccessible source. The uncompressed format ensures no additional quality loss occurs during the conversion process.
FFmpeg demuxes the RM container and decodes the RealAudio stream (Cook, ACELP, or other legacy codecs) into raw PCM samples. These are written to an AIFF container as uncompressed linear PCM at the source's native sample rate and channel layout. Default output is 16-bit/44.1 kHz stereo, though many RM files only contain 22.05 kHz mono audio reflecting their dial-up origins.
AIFF output preserves exactly the quality of the decoded RM audio — no better, no worse. The uncompressed PCM representation ensures zero additional loss during editing or playback. However, the quality ceiling is set by the original RealAudio encoding: typically 32-96 kbps lossy compression optimized for modem speeds. Expect narrow frequency response and audible compression artifacts in the AIFF output.

RM to AIFF conversion produces professional-grade uncompressed audio files from legacy RealMedia sources. While the decoded quality reflects dial-up era encoding, AIFF format enables editing, restoration, and integration into modern audio workflows without further degradation.
