Avidemux Cannot Use That | File As Audio Track =link=

When encountering the error "Avidemux cannot use that file as audio track," it typically indicates that Avidemux is having trouble processing or is incompatible with the specific audio file you've tried to add to your project. This issue can arise due to several reasons, ranging from incompatible file formats to corrupted files. Let's break down the potential causes and solutions:

4. Sampling Rate Mismatch

If your video’s original audio is 48 kHz (standard for video), but your external audio file is 44.1 kHz (standard for CD audio), Avidemux sometimes refuses to combine them without resampling. Since Avidemux does not resample on the fly, it triggers an error.

6. File Path or Permission Issues (Windows Specific)

This sounds trivial, but it happens: The error can appear if the audio file is on a network drive, an external USB drive that is sleeping, or has non-ASCII characters (like ç, ñ, ü) in the filename or folder path.

Review: Avidemux — "Cannot use that file as audio track" error

Summary

• Avidemux is a lightweight, free video editor focused on cutting, filtering, and encoding. A common issue users encounter is the error message: "Cannot use that file as audio track." This review explains causes, diagnostics, and fixes so you can resolve it quickly.

What the error means

• The message indicates Avidemux is unable to import or use the selected audio file or audio stream as the project’s audio track. This can occur when the audio file format, codec, container, or stream properties are unsupported, corrupted, or mismatched with the video.

Common causes

• Unsupported audio codec (e.g., newer/rare codecs not supported by Avidemux’s build).
• Container/codec mismatch: audio inside a container Avidemux can’t parse (e.g., certain MP4/AAC variants, fragmented MP4).
• Variable bit depth or sample format not handled by Avidemux.
• Corrupted or truncated audio file.
• Incorrect file selection — trying to load a video file or subtitle file as audio.
• Channel layout or sample rate unusual (very high sample rates or exotic channel counts).
• Project settings conflict (e.g., video uses parameters requiring specific audio parameters for muxing).
• Platform/build limitations (Windows/Mac/Linux builds differ; some builds lack support for particular libraries).

How to diagnose

1. Check file details: open the audio file in MediaInfo (or use ffprobe) to see codec, container, sample rate, channels, bit depth.
2. Try playing the file in a media player (VLC) to verify it’s not corrupted.
3. In Avidemux, try adding the audio via: Audio → Select Track → Add to confirm the import step.
4. Try the same audio in a new blank Avidemux project to rule out project-specific conflicts.
5. Test with another known-good audio file (e.g., standard MP3 or WAV) to confirm Avidemux audio import works in general.
6. Note any console/log output from Avidemux (run from terminal) — errors there can indicate missing codec support.

Quick fixes (ordered from simplest to more advanced)

• Use a standard format: Convert the audio to WAV (PCM) or MP3 using a converter (VLC, ffmpeg, Audacity), then import the converted file.
  • ffmpeg example:

    ffmpeg -i input.m4a -c:a pcm_s16le output.wav
    

• Re-mux the source file: If the audio is embedded in a problematic container, remux into MP4/MKV using ffmpeg: ffmpeg -i input.mp4 -c copy remuxed.mp4
• Re-encode audio to a supported codec (AAC, MP3, PCM) if codec compatibility is the issue: ffmpeg -i input.m4a -c:a aac -b:a 192k output_aac.m4a
• Repair a corrupted file: try re-encoding via ffmpeg; sometimes this fixes minor corruption.
• Use a different Avidemux build or update: install the latest stable release; some builds include newer codec support.
• As a last resort, use another editor/muxer (MKVToolNix, HandBrake, Shotcut) to combine audio and video, then open resulting file in Avidemux.

Recommended step-by-step using ffmpeg (reliable)

1. Inspect the audio: ffprobe -v error -show_entries stream=codec_name,channels,sample_rate -of default=noprint_wrappers=1 input.ext
2. Convert to WAV: ffmpeg -i input.ext -c:a pcm_s16le -ar 48000 -ac 2 output.wav
3. In Avidemux: Audio → Select Track → Add → choose output.wav

When to seek alternatives

• If you must preserve a specific codec or metadata that Avidemux doesn’t support.
• If your workflow requires advanced audio editing features — use a DAW or richer video editor.
• If Avidemux repeatedly fails despite using standard audio formats — try Shotcut or HandBrake for the muxing/encoding step.

Tips to avoid the issue

• Use common, well-supported audio formats (WAV/MP3/AAC).
• Keep Avidemux updated.
• If sharing projects between OSes, prefer remuxed MP4/MKV containers.
• When in doubt, re-encode audio to PCM WAV before importing.

Verdict

• The error is usually solvable by converting or re-muxing the audio to a standard codec/container (WAV/MP3/AAC). Avidemux remains a useful lightweight tool for simple editing, but its limited codec support means pre-processing audio with ffmpeg or using a different muxer is often necessary.

Would you like a short ffmpeg script tailored to a specific input file (tell me its filename and extension) to convert it into a compatible audio track?

(Remember to run Avidemux from a terminal to capture any error messages if you need further troubleshooting.)

Fix #4: Fix Corrupted Audio Headers

Sometimes the file itself is fine, but the header is messy. Use FFmpeg to "remux" the file without changing quality.

ffmpeg -i problematic.mp3 -c copy fixed.mp3

This rewrites the container headers cleanly. Then try loading fixed.mp3 into Avidemux.

2. Corrupted or Damaged Audio File

If the audio file is corrupted or damaged, Avidemux won't be able to read it.

• Solution: Try playing the audio file in another media player to see if it plays correctly. If not, you may need to find a replacement or repair it if possible.

Comparison: Avidemux vs. Other Tools for External Audio

| Tool | Can add external audio without re-encode? | Handles mismatched codecs? | Ease of use | |------|-------------------------------------------|----------------------------|--------------| | Avidemux | ✅ Only if container & codec match | ❌ No | Very easy | | MKVToolNix | ✅ Yes (always mux without re-encode) | ✅ Yes (MKV supports almost everything) | Moderate | | FFmpeg | ✅ Yes (with CLI) | ✅ Yes (auto converts if needed) | Complex | | LosslessCut | ❌ No (video-only cutting) | N/A | Easy |

Recommendation: If you need to add an MP3 to an MP4 without re-encoding, use MKVToolNix to create an MKV file (which happily accepts MP3). Then use Avidemux to edit that MKV. When encountering the error "Avidemux cannot use that
