If you’re a Microsoft Windows user, you would be familiar with WMV files. WMV file is a pack of video codecs and the corresponding video coding formats developed by Microsoft. WMV stands for Windows Media Video designed to be compatible with the range of Windows operating systems. Because of WMV files’ specific design and structure, they aren’t compatible with MacOS, and if you try to play a .wmv video file on an Apple device, it won’t run.
Similar to other format video files, a WMV file can also turn corrupt or damaged and won’t run in Windows Media Player – the default media player of Microsoft Windows. Below are possible errors or types of corruption that you may face.
- Error Notification: “file could not be played.”
- Frozen Frame/Frame Freeze
- Codec Issue
- No Sound
- Crackled Sound & Distorted Sound
- Video Crash
- Black Screen

Reasons Why the WMV File Turns Corrupt Could Be the Following:
A WMV file could get corrupt because of virus attack; a Windows system can get infected by a virus in situations like when someone surfs non-secured websites, downloads software cracks, transfers corrupted or virus infected files onto the system, etc.
If someone deleted or removed the .wmv file extension – on purpose, the video file won’t remain playable anymore. The trick for playing such media files is to right-click, select Open with, and choose VLC or any other powerful media player.
The WMV video file can also turn corrupt in scenarios when the file download is going on, but somehow either the download was interrupted, or the Internet connection was not stable enough. Because of improperly written file data or missing data blocks, the .wmv video file won’t open or would play a small segment of the full video length.
Sudden or improper system shutdowns also result in files either becoming corrupt or damaged. While a file is being written to some other location or utilized by another program, it is recommended to wait and let the task or process to complete.
How to Fix Corrupt WMV File Issue?
Well, the first thing we’d suggest is to avoid the events listed under the section reasons stating why the WMV file turns corrupt.
Now, what if the WMV video file has already turned corrupt due to some issues, we’ll guide you through methods which on implementation would deliver a proper resolution to the problem.
Open the Corrupt WMV File in VLC
VLC from VideoLAN is a powerful media player application which is designed to work not only on Windows OS but on Linux distributions & MacOS. VLC has native support for a range of video codecs. For the media which fails to open with Windows Media Player or other media players, VLC is the ultimate solution.
You would’ve encountered with the error message above, and there remain no other options, instead of closing the error popup and exiting Windows Media Player, try VLC media player. The same error won’t bother any more; follow the below steps:
- Select and right-click on the corrupt .wmv file and click Open with.
- Choose VLC media player.
- The corrupt .wmv file which was not playing in Windows Media Player now will play in VLC.
Convert WMV File to MP4 Format
If the attempt of playing the corrupt WMV with VLC didn’t result positive then, try changing the file format to .mp4. We’ll be using VLC again for changing the video file format; go through the steps given below:
- Open VLC media player.
- Click on Media and select Convert/Save.
- Click the Add button and select the corrupt .wmv video file. Wait for the file loading to complete first then, move on to the next step. Click on Convert/Save dropdown and select Convert.
- Select Video – H.264 + MP3 (MP4) file format. Click Browse for selecting a path to save the converted .mp4 file and click Start.
Note: Unless you’re aware of what other settings would do when changed, don’t mess with other options available.
- Now, try playing the file using either Windows Media Player or VLC media player. The converted MP4 video file should play.

In this article we share how to repair M4A audio files online, right from your iPhone, Android, Mac or Windows. No need to download or install anything – audio files can be fixed online, from a web-browser.
How Does an M4A File May Get Corrupted?
M4A is a media container similar to MP4, but with audio tracks only (no video).
We often see people come with corrupted M4A files recorded with the Voice Memo app on their iPhone devices. But damaged audio files are quite a common issue across all other platforms too.
Here is how the problem usually occurs:
When recording a voice note, an interview, or any sound with Voice Memo (or any other app), an incoming phone call may interrupt the recording process. As a result, the app may fail to finalize the audio file and it gets corrupted.
You won't be able to play such a damaged M4A file neither on your iPhone, nor on any other device, since it misses metadata and indices due to the interrupted recording.
In the worst case, a part of the recorded audio data at the end of the file may also be lost due to how Voice Memo app writes data – we'll cover this later in this article.
Repair Corrupted Amr Audio File Online
The same issue may happen as a result of some glitch, or if the device goes off unexpectedly due to power loss during the recording process (e.g. if the battery dies).
When trying to play a corrupted M4A file, you will either see an error, or the player will look like it's playing the file, but there won't be any sound and the timeline won't move.
If you have a similar problem with a damaged M4A file, there are good chances to repair it – just follow instructions bellow:
Follow These Steps to Fix Corrupted M4A Files
Step 1
First, register a free account at Restore.Media.
This is an online media recovery tool that can repair M4A files right in a web-browser. So, if you're on iPhone, Android, or any other device, there is no need to install anything.
Please note that Restore.Meida is not a free tool. There is a small fee if you want to download the repaired file.
Step 2
After submitting the registration form, you will receive a confirmation email. Make sure to click on the link provided in the email to start repairing your file.
If you can't find the confirmation email, make sure to check the spam folder just in case it went there by mistake.
Step 3
Once you click on the link in the email, you should see a welcome page.
Click Get started to proceed:
Step 4
On this step, choose the device you used to record the damaged M4A file.
Restore.Media has multiple different recovery algorithms tailored to specific device models. Make sure to choose the right device in the list for higher recovery success rate.
If you can't find your device in the list, just select Generic M4A file (audio only) and then enter your device model in the text field manually.
If you don't know what device was used to record the audio file, select Generic M4A file (audio only) and leave the text field empty.
Step 5
Now, create a recovery task. Just give the task a name – whatever makes sense for you, and click Next:
Step 6
Upload your corrupted M4A file:
Step 7
On this step Restore.Media will either start repairing your file immediately, or ask you to upload a sample file.
If you're asked to upload a sample file, this usually means that the tool needs to extract metadata from a valid playable M4A file and insert it into the corrupted one.
For a sample file, you can take any working (not corrupted) M4A audio file recorded with the same device and the same settings (e.g. mono/stereo, bit rate, etc.) as the damaged file.
If you don't have a sample file, you can either record it (a 1-minute audio file should be enough), or contact us and our engineers will try to find a sample file for you.
Step 8
Once everything has been set up, Restore.Media will start repairing your corrupted M4A file automatically. If the file has been fixed successfully, you should see the following screen:
Repair Corrupt Audio Files
Here you can play your repaired file.
Please note that the audio is in low quality just so you can check if it actually has been fixed. You can download the repaired file in the original quality after paying a small fee.
Before you download the file, we recommend that you check the entire sound track, including the last few seconds.
If you're happy with the results, click the large green button Preview looks good. Download the complete recovered file.
If there is anything missing from the track, please read the notices below the player and follow appropriate instructions.
Please note.
There is a known problem when trying to fix corrupted Voice Memo (M4A) files.
After repairing a file, it may appear that there is either no audio data, or a part of the data is missing at the end of the file.
This occurs due to how the Voice Memo app works.
When recording audio, the app writes it to its cache and then saves it to the iPhone's permanent memory. If the recording process is interrupted unexpectedly, the Voice Memo app may fail to save the data from its cache to the iPhone's memory and the data is lost beyond recovery.
There is no way to recover audio data from the app's cache, unfortunately, since it acts as a temporary memory.
Oddly, the corrupted M4A file may indicate its expected length, even though it does not actually contain the recorded data that has been lost in the app's cache.
If your repaired M4A file misses a part of the recorded data, please pay attention to the total extracting ratio as shown below.
If the value is close to 100%, this means that all the actual data has been recovered, nothing is left behind, no matter what the Voice Memo application tells you.
Unfortunately, we won't be able to recover more data than there is in the audio preview.

We hope that with this guide you will repair M4A files without any issues. If you still have any questions or need help, please free to contact us.
