Opus to AIFF Converter
Generate a ready-to-run FFmpeg command to convert any Opus file to AIFF and compare the two formats side by side.
FFmpeg Command Generator
Also accepts .ogg and .webm files containing Opus audio.
Opus source is usually 48000 Hz. Leave unset to preserve it.
Command copied to clipboard.
Install FFmpeg
Batch Convert (Linux / macOS)
for f in *.opus; do
ffmpeg -i "$f" "${f%.opus}.aiff"
done
Run in the folder containing your Opus files. Adds -ar if you selected a sample rate above.
Alternative Tools
VLC Media Player
Media > Convert/Save > select input > choose Audio AIFF profile > Start. Free and cross-platform.
Audacity
Requires the optional FFmpeg library plugin. File > Import > Audio, then File > Export > Export as AIFF.
When to Convert Opus to AIFF
DAW compatibility
Logic Pro, GarageBand, and Pro Tools work natively with AIFF. Importing Opus directly is not supported by most DAWs without a plugin.
Lossless editing headroom
Working with uncompressed PCM in a DAW avoids decode artifacts during repeated edits, pitch-shifting, or time-stretching.
Apple ecosystem playback
iTunes, macOS Finder, and older Apple hardware play AIFF natively. Opus support varies across Apple software versions.
Audio middleware import
Game audio tools such as Wwise and FMOD often accept AIFF as a source asset before re-encoding for target platforms.
Opus vs AIFF — Format Comparison
| Property | Opus | AIFF |
|---|---|---|
| Compression | Lossy | None (lossless PCM) |
| Standard | IETF RFC 6716 (2012) | Apple / EA IFF 85 |
| Patent status | Royalty-free | Proprietary (Apple) |
| Typical size (3 min) | ~3–7 MB at 128 kbps | ~30–50 MB |
| Bitrate range | 6 – 510 kbps | Fixed by sample rate |
| Latency | 2.5 – 60 ms | N/A (uncompressed) |
| Container | .opus / .ogg / .webm | .aiff / .aif |
| Browser support | Chrome, Firefox, Edge, Safari 16.4+ | Limited |
| DAW support | Poor (plugin needed) | Excellent |
| Best for | Streaming, VoIP, web apps | Studio / DAW editing |
Quality note
Converting lossy Opus to lossless AIFF does not restore lost audio data. The output AIFF is uncompressed but contains only the quality that survived Opus encoding. For archival purposes, keep the original Opus file and export the AIFF as a working copy only.
Summary
Generate a ready-to-run FFmpeg command to convert any Opus file to AIFF and compare the two formats side by side.
How it works
- Enter the name of your Opus file in the input field (e.g., recording.opus).
- The output AIFF filename is set automatically using the same base name.
- Optionally adjust the output sample rate if your DAW requires a specific rate.
- Copy the generated FFmpeg command with one click.
- Paste the command into your terminal and press Enter — FFmpeg decodes the Opus stream and writes an uncompressed AIFF file.
- Open the resulting .aiff file in your DAW or audio editor to continue working.
Use cases
- Import Opus recordings from browsers or WebRTC sessions into Logic Pro or GarageBand.
- Convert podcast interview recordings saved as Opus into AIFF for DAW editing.
- Bring downloaded or archived Opus audio into Pro Tools, which prefers AIFF over Opus.
- Prepare Opus game audio assets as uncompressed AIFF for import into audio middleware.
- Convert Opus voice memos to AIFF before editing them in professional audio software.
- Transcode Discord or browser-recorded Opus clips to AIFF for post-production.
- Batch-convert a folder of Opus files to AIFF before archiving in a lossless format.
- Rewrap Opus music files as AIFF for playback on Apple hardware that does not support Opus.
