Convert DV to AIFF — Free Online Tool
Extract and convert the PCM audio track from a DV camcorder file into a high-quality AIFF file, transcoding from 16-bit little-endian PCM (pcm_s16le) to Apple's 16-bit big-endian PCM format (pcm_s16be). AIFF is the native uncompressed audio format for macOS and professional audio workflows, making it ideal for editing DV footage audio in Logic Pro or Final Cut Pro.

DownloadHow It Works
DV files store audio as 16-bit little-endian PCM (pcm_s16le) — a raw, uncompressed format natively recorded by DV camcorders. AIFF also stores audio as uncompressed PCM, but uses big-endian byte ordering (pcm_s16be), the convention Apple chose for the format. During this conversion, FFmpeg discards the DV video stream entirely and re-encodes only the audio, flipping the byte order from little-endian to big-endian. Because both formats use uncompressed 16-bit PCM, there is zero perceptible quality loss — the difference is purely structural, not auditory. The resulting AIFF file contains the same audio samples as the original DV recording, just packaged in a container and byte order that macOS and Apple professional applications read natively.
What Each Flag Does
| Flag | What it does |
|---|---|
ffmpeg
|
Invokes the FFmpeg tool. In this browser-based tool, FFmpeg.wasm runs this command entirely in your browser using WebAssembly — no file is sent to any server. |
-i input.dv
|
Specifies the input DV file. FFmpeg reads the DV container, which carries a dvvideo video stream and a pcm_s16le audio stream recorded by the camcorder. |
-c:a pcm_s16be
|
Sets the audio codec for the output to 16-bit big-endian PCM, which is the byte order required by the AIFF format. This transcodes the DV file's little-endian PCM audio to big-endian without any perceptible quality change. |
output.aiff
|
Defines the output filename and format. The .aiff extension tells FFmpeg to use the AIFF container, and combined with pcm_s16be audio, produces a file natively compatible with macOS and Apple professional audio applications. The DV video stream is automatically dropped because AIFF is audio-only. |
Common Use Cases
- Importing audio from a DV camcorder recording into Logic Pro or GarageBand, which natively prefer AIFF over DV's raw PCM
- Extracting the on-set audio recorded to DV tape for use as a reference track or sync guide in Final Cut Pro X audio editing workflows
- Archiving the audio from old family or event DV camcorder tapes as standalone AIFF files for long-term macOS-compatible storage
- Sending the audio from a DV interview or documentary shoot to a sound editor working in a Mac-based studio environment who requires AIFF deliverables
- Separating the audio from a DV news or broadcast recording to produce a clean transcript or podcast episode without transcoding to a lossy format like MP3
- Preparing DV-recorded voiceover or field audio for import into audio restoration tools like iZotope RX, which accept AIFF natively
Frequently Asked Questions
No — this conversion is effectively lossless. Both the DV format and AIFF use uncompressed 16-bit PCM audio; the only difference is byte order (little-endian in DV versus big-endian in AIFF). FFmpeg rewrites the raw sample data with the bytes in the correct order for AIFF, but the actual audio values are identical. You will not hear any difference between the original DV audio and the resulting AIFF file.
The video stream is completely dropped. AIFF is a pure audio-only format with no container support for video, so FFmpeg extracts only the pcm_s16le audio track from the DV file and writes it into the AIFF container. If you need the video preserved, you would need to convert to a different output format such as MOV or MP4 instead.
DV stores audio as pcm_s16le (16-bit signed little-endian PCM), but AIFF requires big-endian PCM (pcm_s16be). These are technically different codecs from FFmpeg's perspective, so a direct stream copy with '-c:a copy' would fail or produce unplayable audio. The '-c:a pcm_s16be' flag tells FFmpeg to re-encode the audio by swapping the byte order, which is the minimal transcoding step needed to produce a valid AIFF file.
AIFF supports higher bit depths including pcm_s24be and pcm_s32be, but the original DV audio is only 16-bit. You can change the output codec by modifying the command to '-c:a pcm_s24be', but upsampling bit depth from a 16-bit source does not recover lost audio information — it simply pads the samples with zeros. For DV source material, 16-bit AIFF is the appropriate and accurate choice.
You can batch process DV files using a shell loop. On macOS or Linux, run: 'for f in *.dv; do ffmpeg -i "$f" -c:a pcm_s16be "${f%.dv}.aiff"; done'. On Windows Command Prompt, use: 'for %f in (*.dv) do ffmpeg -i "%f" -c:a pcm_s16be "%~nf.aiff"'. This applies the same conversion to every DV file in the current directory and outputs a matching AIFF file for each.
DV files embed minimal metadata such as timecode and recording date in their stream headers, but AIFF has a very limited metadata specification. FFmpeg will attempt to map common metadata fields, but DV-specific fields like tape name and timecode are generally not preserved in the AIFF output. If metadata preservation is critical, consider using a format with richer metadata support, or extract relevant metadata from the DV file separately before conversion.
Technical Notes
DV audio is recorded as pcm_s16le at either 48 kHz (the standard for most DV camcorders) or 32 kHz (used in some older or consumer-grade DV devices), always at 16-bit depth. AIFF's default codec pcm_s16be matches the 16-bit depth exactly, and FFmpeg preserves the original sample rate from the DV file without resampling — so a 48 kHz DV recording produces a 48 kHz AIFF file. The primary technical transformation is purely a byte-order swap. The output file size will be slightly larger than the audio portion of the DV file would suggest because AIFF includes its own container overhead, but the difference is negligible for typical audio lengths. AIFF does not support multiple audio tracks or subtitles, so if the DV file somehow contains additional streams (rare, as DV only supports a single stereo or two-channel audio pair), only the primary track will be mapped. The resulting AIFF is fully compatible with macOS Finder previews, iTunes, Logic Pro, Final Cut Pro, and any standard audio tool on Apple platforms.
