About this app

Batch add audio to hundreds of videos in a single run — replace original sound, mix audio tracks, adjust volume, and process the entire batch without editing every video individually.

Batch Audio Adder: For Video is a tool for batch adding audio and music to videos. Select dozens or hundreds of video files, add audio, configure everything once, and process the entire batch.

Instead of hundreds of repetitive actions — one setup and one batch video processing workflow.

ONE AUDIO TRACK FOR HUNDREDS OF VIDEOS

Choose one audio file and add it to an entire batch of videos at once.

This is useful when dozens or hundreds of Instagram Reels, YouTube Shorts, TikTok videos, or other clips need the same music, voice-over, or audio track.

No need to open every video, add the same sound, and export each file separately.

MANY VIDEOS + MANY AUDIO FILES

Need different audio for every video?

Select the same number of videos and audio files. Batch Audio Adder automatically pairs them in order:

Video 1 → Audio 1
Video 2 → Audio 2
Video 3 → Audio 3

Review all file pairs before processing.

If the number of files does not match, the app does not guess which audio belongs to which video or create incorrect results.

REPLACE AUDIO IN VIDEOS

Use Replace to completely remove the original video sound and add new audio or music.

Apply the same mode to the entire selected batch at once.

Perfect for bulk replacing sound, music, or audio tracks across a large number of video files.

MIX AUDIO WITH THE ORIGINAL SOUND

Use Mix to add music or new audio to a video while keeping its original sound.

Adjust separately:

* new audio volume;
* original audio volume.

Keep voices or ambient sound from your videos while adding music on top — without manually editing every file.

LOOP SHORT AUDIO

If your audio is shorter than the video, there is no need to duplicate the audio track manually.

Choose:

* Loop — repeat the audio until the video ends;
* Play Once — play the audio once without repeating it.

If the audio is longer than the video, it automatically adjusts to the duration of the result.

BATCH VIDEO PROCESSING

Batch Audio Adder is built for working with large numbers of video and audio files.

Select videos → select audio → choose Replace or Mix → adjust volume → process the entire batch.

The app processes your selected videos in sequence and shows the progress.

Processing can continue in the background, so you do not need to keep the app open while waiting.

ALL FINISHED VIDEOS IN ONE FOLDER

Choose a results folder and keep your finished video files together in one place.

View processing status, open finished videos, share them, and retry failed operations.

FOR REELS, SHORTS, TIKTOK & LARGE VIDEO BATCHES

Batch Audio Adder is useful for:

* Instagram Reels;
* YouTube Shorts;
* TikTok;
* content creators;
* SMM professionals;
* marketing;
* bulk video content creation;
* large collections of short videos.

This is not a complicated video editor. It is a specialized batch tool for anyone who needs to quickly add audio to videos, replace sound, mix music with original audio, and process large numbers of video files in one workflow.

Process the entire batch in one run instead of repeating the same actions for every video.

What’s new

Batch add audio to videos using one track for the entire batch or ordered video-to-audio pairing. Replace original sound, mix audio tracks, adjust volumes separately, and use Loop or Play Once. Background processing, progress tracking, retry for failed files, and convenient result saving are included. The interface, localization, and overall stability have also been improved.
