What to check before sending audio to a video editor

You have a voice recording, music track, or sound effect ready for a video, but a file that plays on its own can still cause trouble in an editing project. It might have unwanted silence, the wrong channel layout, or an export format that makes editing harder.

Check the clip before you import it. The Audio Editor can help you listen, trim, join, and export audio in your browser. The checks below help you avoid surprises on the video timeline.

Prepare the audio file

1. Open the Audio Editor and open the audio file you plan to use. Keep an untouched copy of the original in case you need to start over.
2. Listen to the whole clip, especially the first and last few seconds. Check that the sound starts where you expect, ends cleanly, and does not contain an accidental click, cutoff word, or long unwanted pause.
3. Cut away extra silence or unwanted material at the beginning and end. If a file contains several separate clips, arrange or join them as needed. You can also split by silence when pauses are useful boundaries, but listen to each split before keeping it.
4. Listen for problems that are easy to miss while recording, such as a sudden volume change, crackling, a repeated phrase, or a voice that gets cut off. Do not change speed or pitch unless that is part of the intended edit.
5. Export a copy as WAV or MP3, based on what your video editor accepts. Import that copy into the project and check it once more in context with the picture.

File names such as interview-clean.wav or music-final.mp3 make it easier to distinguish the prepared file from the original. Keep the source file until the video edit is finished.

Choose the right format and channel layout

Choose WAV for editing when possible

WAV is usually the safer handoff format for an editing project because it can hold uncompressed audio. It takes more storage space than MP3, but it avoids adding another round of lossy compression when you make an edit. If your editor asks for a specific WAV format, follow that requirement.

Use MP3 when file size or compatibility matters

MP3 files are smaller and are widely supported. They can be convenient for a quick sound effect or a finished music track, especially when your video editor accepts them. However, MP3 uses lossy compression. Exporting an MP3 repeatedly does not restore detail that was discarded, so avoid converting the same file back and forth.

Check whether the audio is mono or stereo

Mono has one audio channel, while stereo has two. A single-person voice recording is often fine in mono, and music or room sound may be stereo. Neither is automatically better. Make sure the file plays through the speakers or headphones as expected, and check that the video editor does not treat a mono voice track as silent on one side.

The clip sounds clean and starts at the right point

The file is likely ready to import. Place it on the timeline and listen with the video playing. The edit may reveal a mismatch that was hard to notice on its own, such as a voice starting too early or music covering speech.

You hear crackles, distortion, or sudden changes

These are signs to investigate before editing. Distortion may already be present in the source recording. Trimming or exporting it will not repair clipped sound, so return to the original recording if you can and use a cleaner take.

The sound is only on one side

Check whether the source is mono or stereo and how the video editor places it on the timeline. If the original recording itself is missing a channel, exporting it again may not bring that sound back. Keep the original so you can compare before changing the channel setup.

Fix common handoff problems

1. Check the video editor's supported formats. If it cannot open the current file, export a WAV or MP3 copy from the Audio Editor and try that. Use the format and settings requested by your editing project when they are specified.
2. Remove extra silence, not useful room tone. Trim empty space that delays the start, but do not cut so tightly that the first word or a natural breath disappears. Listen to the edit from a few seconds before the cut.
3. Compare the channels. If speech is audible only on one side, check the editor's track or clip channel settings. Do not convert stereo to mono just to fix a playback issue until you know the source really needs that change.
4. Use the original if the audio is distorted. A clean export cannot undo clipping, which happens when sound is recorded too loudly and becomes harsh or broken. Lowering the volume afterward may make the distortion quieter, but it will still be there.
5. Make a fresh export if the timeline uses an old copy. Export the prepared file with a new, clear name, then remove or replace the earlier version in the video project. This avoids editing the untrimmed source by mistake.

Match the audio to the video project

Many video projects use a sample rate of 48 kHz, while music files commonly use 44.1 kHz. The sample rate describes how often audio is measured per second. A difference does not always prevent a file from playing, because video editors can often convert it during import or export. Check your project requirements first, and do not raise a file's sample rate just to make the number larger. Upsampling does not restore detail that was not in the recording.

Also check the timeline after import. Confirm the clip begins at the intended frame, plays at the expected speed, and remains in sync with speech or action. If the picture and sound drift apart, check whether the original recording has a different duration or frame rate context before changing the audio speed.
