How to Use Audio Analyzer in VideoProc Vlogger

Step 0Create a new project in VideoProc Vlogger

Launch VideoProc Vlogger. When a project panel pops up, complete the general settings to create a new project.

Step 1Load audio to VideoProc Vlogger

After creating a new project in VideoProc Vlogger, you can add an audio file (.mp3, .aac, .m4r, .ogg, etc.) and a video from your computer to the media library, and then drag them to the timeline.

Step 2Open the audio analyzer

Click to select the audio track. Hit the Audio option under the preview window to open the audio editor panel.

Move to the left side of the top audio editing toolbar, and click Analyzer to open the analysis panel.

Step 3Choose an audio analysis mode

Option 1: Audio Onset

If you want to analyze music with obvious percussion or abrupt sound effects, select Audio Onset.

In the Threshold of Onsets option, you can set the value in dB, under which the onset will not be detected.

If the percussion in the audio is strong, increasing the threshold should analyze and mark peaks of the audio waveform precisely. If the percussion is quite weak, you need to decrease the threshold to make sure it can be detected, meanwhile more detections might appear in the result.

Option 2: Audio Beat

If you want to analyze rhythmic music e.g. calm, upbeat, or electronic songs, select Audio Beat.

In the Highlights Interval option, you can set the value of beats to decide the interval between every two highlights.

In the detection results, red points represent highlights and gray points represent general beats. If the highlights are located on undesired beats, you can change the Offset to move them forward.

Option 3: Audio Silence

If you want to find silences in the audio file, select Audio Silence.

By default, sounds under -90dB will be treated as silence. You can customize the threshold to detect audio at varied volume levels.

Step 4Add markers

When the audio analysis is done, many points show up to give you hints where the onset of a sound, the beat in a measure of music, or the silent moment is.

Press and hold the mouse to decide a range to add markers which will turn green then. Click the Add Maker option at the bottom. And you can double-click on the waveform to add a marker manually if any beat is missing in the results.

Finally, hit the Apply button to get back to the main interface, and you can sync the video to the beat of the music efficiently with the help of these markers.

Now free download and install VideoProc Vlogger to analyze the audio for editing video to the music/sound with ease.
