M2TS is the BDAV MPEG-2 Transport Stream container that AVCHD camcorders (Sony, Panasonic, Canon) and Blu-ray discs use to hold HD video alongside a Dolby Digital, DTS, or LPCM audio track. AIFC (AIFF-C) is Apple's audio container, native to macOS and pro tools like Logic Pro. This converter is an audio extraction: it pulls the sound out of the M2TS and writes it to an AIFC file — the video is discarded, and on this tool the audio is written as uncompressed PCM by default (same data class as WAV, roughly 10 MB per minute).
M2TS Format at a Glance
| Property | Value |
|---|---|
| Container | BDAV MPEG-2 Transport Stream (.m2ts / .mts) |
| Used by | AVCHD camcorders, Blu-ray discs |
| Video codecs | H.264/AVC, MPEG-2, or VC-1 |
| Audio codecs | Dolby Digital (AC-3), DTS, or LPCM; HD audio optional |
| Output here | Audio track only — video is dropped |
| Best for | Recording and authoring HD video, not audio editing |
AIFC Format at a Glance
| Property | Value |
|---|---|
| Full name | Audio Interchange File Format – Compressed (AIFF-C) |
| Introduced | 1991 by Apple (AIFF itself dates to 1988) |
| Payload | PCM by default here; the spec also allows codecs like μ-law |
| Byte order | Big-endian (Apple's macOS "sowt" variant is byte-swapped PCM) |
| Compression | None at the default setting — same size class as WAV |
| Best for | Editing on macOS in Logic Pro, GarageBand, or Final Cut Pro |
How to Convert M2TS to AIFC
- Upload Your M2TS File: Drag and drop your file or click "+ Add Files". You can queue several M2TS clips and process them with the same settings.
- Set Audio Channel and Sample Rate: Leave both on "Original" to keep the source layout, or pick Mono/Stereo and a sample rate (such as 44100 Hz or 48000 Hz) to match your project.
- Trim the Track (Optional): Use the Trim control to set a start time and duration if you only need part of the recording — leave it "Unchanged" to keep the whole track.
- Convert and Download: Click "Convert" and download your AIFC file. No sign-up, no watermark.
Frequently Asked Questions
Does AIFC make the file smaller than the original M2TS?
No — and that surprises people. AIFC here is written as uncompressed PCM, the same data class as WAV, so it lands at roughly 10 MB per minute of stereo CD-quality audio. M2TS uses lossy or compact audio (AC-3 is typically 192–640 kbps), so the AIFC is often larger than the audio inside the source clip, even though the video is gone. If you want a small, shareable file, extract to MP3 instead.
Will extracting to AIFC improve the audio quality?
No conversion can recover quality that was never recorded. If the M2TS holds LPCM audio, writing it to PCM AIFC is essentially a lossless re-wrap — the samples are unchanged. If the M2TS holds AC-3 (Dolby Digital), decoding it to PCM AIFC stops any further loss but does not undo the original lossy encoding. In our testing, a one-minute AVCHD clip with stereo audio produced an AIFC of roughly 10 MB at 44.1 kHz, matching the math for uncompressed PCM.
Is AIFC the same as AIFF?
They are closely related. AIFF (1988) holds only uncompressed PCM, while AIFF-C / AIFC (1991) is a superset that can carry compressed codecs but also handles plain PCM. macOS itself usually stores "AIFF" as an AIFF-C "sowt" variant, which is uncompressed PCM with swapped byte order. At the PCM default, an AIFC from this tool is sonically identical to the equivalent AIFF.
Should I use AIFC or WAV?
Both are uncompressed PCM with identical sound at the same bit depth and sample rate; the difference is the wrapper. AIFF/AIFC is Apple's big-endian format and feels most at home in Logic Pro, GarageBand, and Final Cut Pro. WAV is Microsoft's little-endian format and is the safer pick on Windows and for the broadest cross-app compatibility. If you are on a PC or sharing widely, use M2TS to WAV instead.
What sample rate should I choose?
Leave "Audio Sample Rate" on "Original" to preserve exactly what the camcorder recorded — that avoids an unnecessary resampling step. AVCHD audio is commonly 48000 Hz. Pick 44100 Hz only if your project or CD master needs that rate, since resampling is a one-way change you cannot reverse without quality loss.
Is my file kept private?
Yes. Your M2TS is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public.
