Extract Audio from MOD to AIFF — Free Online Tool
Extract lossless audio from MOD camcorder footage into AIFF format, converting the MPEG-2 encoded audio stream to uncompressed PCM. This is ideal for archiving or professionally editing audio captured on JVC or Panasonic camcorders without any quality degradation.

DownloadHow It Works
MOD files store audio using lossy codecs (typically Dolby Digital AC-3 or MPEG-1 Audio Layer II) inside a modified MPEG-PS container. During this conversion, FFmpeg strips the video stream entirely and decodes the compressed audio, then re-encodes it as 16-bit big-endian PCM (pcm_s16be) and wraps it in an AIFF container. Because the source audio is lossy and the output is lossless, no further quality loss occurs after decoding — the AIFF file is a lossless representation of exactly what was in the MOD file's audio track. The output file will be significantly larger than the original audio portion of the MOD file since PCM audio is uncompressed.
What Each Flag Does
| Flag | What it does |
|---|---|
ffmpeg
|
Invokes the FFmpeg tool, which handles all demuxing, decoding, and encoding in this conversion. In the browser, this runs via FFmpeg.wasm compiled to WebAssembly — the same command works identically on a local desktop FFmpeg installation. |
-i input.mod
|
Specifies the input MOD file — the camcorder footage from a JVC or Panasonic device. FFmpeg automatically detects the modified MPEG-PS container and identifies the video and audio streams inside it. |
-vn
|
Disables video output entirely, discarding the MPEG-2 video stream from the MOD file. This is essential because AIFF is an audio-only format and cannot contain a video stream — omitting this flag would cause an error. |
-c:a pcm_s16be
|
Encodes the audio as 16-bit signed big-endian PCM, which is the standard uncompressed codec for AIFF files. The MOD file's lossy audio (AC-3 or MPEG Audio) is decoded and then stored as raw PCM samples, producing a lossless output with no further compression artifacts. |
output.aiff
|
Defines the output filename and format. FFmpeg uses the .aiff extension to automatically select the AIFF container, which combined with the pcm_s16be codec produces a fully standard, Apple-compatible lossless audio file. |
Common Use Cases
- Archiving audio from JVC or Panasonic camcorder footage in a lossless, uncompressed format for long-term preservation
- Importing camcorder-captured speech or ambient sound into Final Cut Pro or Logic Pro X, which natively prefer AIFF on macOS
- Separating event audio (weddings, concerts, speeches) from MOD video files to edit the audio independently in a DAW
- Preparing a clean, uncompressed audio track from camcorder footage for professional post-production mixing or mastering
- Extracting audio from MOD files to analyze waveform data in tools like Adobe Audition that work best with uncompressed formats
- Creating lossless audio masters from legacy camcorder recordings before the original MOD files are migrated or deleted
Frequently Asked Questions
No — the audio in MOD files is already lossy-compressed (typically AC-3 or MPEG Audio), so some quality was lost at the time of recording. Converting to AIFF produces a lossless, uncompressed copy of that audio, meaning no additional quality is lost in this conversion. The AIFF file will faithfully represent the audio as it exists in the MOD file, but it cannot recover detail lost by the camcorder's original compression.
AIFF stores audio as raw, uncompressed PCM samples — in this case 16-bit big-endian — so there is no compression reducing the file size. A MOD file's audio stream is compressed (often at 192–384 kbps for AC-3), while 16-bit stereo PCM at 48kHz produces approximately 5.6 MB per minute. This size increase is expected and is the nature of lossless uncompressed audio storage.
Yes — AIFF was developed by Apple and is natively supported across macOS applications including Final Cut Pro, Logic Pro X, GarageBand, and QuickTime Player. It is also supported by cross-platform tools like Adobe Audition, Audacity, and Reaper. The pcm_s16be codec used here is the standard AIFF codec and will open correctly in virtually any software that supports the format.
MOD files store minimal metadata, and AIFF has limited metadata support compared to formats like FLAC or MP4. FFmpeg will attempt to copy any available metadata tags, but camcorder MOD files typically contain little beyond technical stream information such as sample rate and channel count. Do not expect rich metadata like recording date or scene titles to transfer automatically.
Replace pcm_s16be in the command with a higher bit-depth codec supported by AIFF. For 24-bit audio use '-c:a pcm_s24be', for 32-bit use '-c:a pcm_s32be', and for 32-bit float use '-c:a pcm_f32be'. For example: ffmpeg -i input.mod -vn -c:a pcm_s24be output.aiff. However, since the MOD source audio is lossy and typically recorded at 16-bit resolution, choosing a higher output bit depth will not recover any additional detail — it will simply store the same audio in a larger container.
Yes — on Linux or macOS you can run a shell loop such as: for f in *.mod; do ffmpeg -i "$f" -vn -c:a pcm_s16be "${f%.mod}.aiff"; done. On Windows Command Prompt use: for %f in (*.mod) do ffmpeg -i "%f" -vn -c:a pcm_s16be "%~nf.aiff". This processes each MOD file in the current directory and outputs a corresponding AIFF file. The in-browser tool handles one file at a time, so the FFmpeg command is especially useful for batch processing large collections of camcorder footage.
Technical Notes
MOD is a camcorder-specific format used by JVC and Panasonic devices, where MPEG-2 video is paired with audio encoded as Dolby Digital (AC-3) or MPEG-1 Audio Layer II, all wrapped in a modified MPEG Program Stream container. FFmpeg has solid support for demuxing MOD files, though some older or unusual camcorder models may produce non-standard variants. The output codec pcm_s16be (16-bit signed big-endian PCM) is the canonical audio codec for AIFF and is universally compatible with any AIFF-capable software. AIFF uses big-endian byte ordering (inherited from the Motorola 68000 era and Apple's historical architecture), which distinguishes it from WAV's little-endian PCM — both are lossless but not interchangeable at the binary level. If your downstream workflow requires little-endian PCM, WAV would be the appropriate output format instead. The '-vn' flag is critical here: without it, FFmpeg would attempt to encode the MPEG-2 video stream, which AIFF cannot contain, causing an error. File size for the output should be estimated at roughly 10 MB per minute for stereo 16-bit audio at 48kHz, which is typical for camcorder footage.
