WAV (Waveform Audio File Format) is the definitive uncompressed audio standard, co-developed by Microsoft and IBM in 1991. It stores raw PCM (Pulse Code Modulation) samples in a RIFF (Resource Interchange File Format) container — no compression, no processing, no codecs needed. Converting Opus to WAV decodes the Opus audio and captures every sample in uncompressed form, creating the cleanest possible representation of what the Opus encoder preserved.
Opus, standardized as IETF RFC 6716, is the most efficient lossy audio codec available — but it is still lossy. WAV provides the uncompressed ground truth of the decoded Opus audio. Every DAW (Digital Audio Workstation), every audio editor, every operating system, every programming language's audio library reads WAV files without any codec dependency. It is the lingua franca of digital audio.
Professional audio editing always starts with uncompressed formats. Pro Tools, Audacity, Ableton Live, FL Studio, and Reaper all work most efficiently with WAV files — no decoding overhead, no codec compatibility issues, and no risk of generational quality loss from repeated edits. If you have Opus recordings that need professional post-production (noise reduction, EQ, compression, normalization, splicing), converting to WAV first provides the best working copy.
WAV is also the standard for audio analysis, scientific research, and speech processing. Acoustic analysis tools, machine learning training pipelines, speech recognition engines, and audio forensics software all expect WAV input. If you are processing Opus recordings through any kind of audio analysis pipeline, WAV is the expected input format.
FFmpeg decodes the Opus stream (libopus, typically 48 kHz mono or stereo) and writes linear PCM audio (signed 16-bit or 24-bit little-endian) in a RIFF/WAV container. The default output is 16-bit at 44.1 kHz stereo, producing approximately 10.6 MB per minute. At 24-bit/48 kHz (matching Opus's native rate), the file grows to approximately 16.6 MB per minute. The 4 GB WAV file size limit (32-bit RIFF header) allows approximately 6.7 hours at CD quality.
WAV output is a perfect PCM representation of the decoded Opus audio. No compression artifacts are added — the only artifacts present are those from the original Opus encoding. Using 48 kHz output preserves Opus's native sample rate without resampling. The resulting WAV can be edited, processed, and re-exported without any generational loss.
