With Machete, you can add an audio to a video file, or replace an existing audio stream (track) with a new one. Machete adds an audio stream to an entire video file starting at the beginning (from zero (0) position) regardless of any current playback position set within a file. With Machete, you can add up to four audio streams to one file, except in FLV files which cannot contain more than one audio stream.
Step 1. To add an audio to a file, you need to prepare the initial video file first. If this file already contains an audio stream, you need to delete it. For this, use menu File-> Save video stream as... to separate the video stream and save it as a new video file. After that, you can open the resulting file and edit it as necessary (e.g. cut out fragments that you do not need).
! Check that your file does not contain an audio stream: in this case, the LED panel displays no information about an audio stream format (see picture on the left).
Step 2. Prepare the audio file that you want to add as an audio stream (track) to your video file. Remember, this should be a WMA, MP4 or FLV audio file (depending on the original format of your video file). Audio files in MP3 format can be added to both WMV and FLV video files, as well as to AVI and MP4 files. For example, you can utilize audio streams from other MP4, WMV or FLV video files.
To make an audio file from the audio stream of a video file, open an MP4, WMV or FLV video file with the audio stream you want to extract in Machete and use menu File-> Save audio stream as... to separate the audio stream and save it as a new audio file.Step 3. Open the video file prepared in Step 1 and go to menu File-> Add audio stream... Select the audio file prepared in Step 2 from the list and press Open. The resulting file will be saved under the name of original file automatically.
Alternatively, you can select an AVI, MP4, WMV or FLV file that contains the required audio stream (depending on the original format of your video files). In this case, Machete will extract the audio stream from this file and add it to the initial video file.
! Please note that the menu Add audio stream... may be unavailable if the opened video file already contains an audio stream or it has not been saved after editing.
Note: When adding an audio to a video file, make sure that their lengths are approximately the same. If they differ, you would need to edit the video and/or audio streams with Machete beforehand (for example, deleting unnecessary fragments) in order to make their lengths equal.
! Otherwise, Machete will trim the longer stream (either audio or video) while it is replacing the audio stream. The trimmed part will be discarded.

FREE Machete Lite:
MACHETE VIDEO EDITOR LITE
Machete Video Editor Lite is a free version of our video editor Machete. Similar to Machete, the Lite edition is designed for quick and simple "slicing" of your video files: you can delete unnecessary fragments (e.g. cut out commercials), copy, move, mix and save individual pieces. Also, you can use the software to remove audio tracks from video files.
Unlike Machete, the Lite edition only supports the limited number of formats - in the current version, only AVI and WMV files. Also, the Lite edition does not support the editing of audio files, and you can't use it to add or replace an audio stream. All other features of the main edition are available in the Lite one as well: the ability to losslessly edit video files and the extraordinary ease of use which does not require any specific knowledge or previous experience in video editing. Because of Machete Video Editor Lite's simple and intuitive interface you can edit your files within a few minutes after downloading the program, even if you never edited a video file before.
Below is the list of functions available in Machete Video Editor Lite:
• Play AVI and WMV video files • Edit WMV video files (*.wmv, *.asf)
- most video codecs supported: WMV, MSS and others
- most audio codecs supported: WMA, MP3 and others
- most video codecs supported: DV (Digital Video Type 1, 2), DivX, XviD and others
