Will my voiceover replace the original audio?

By default the tool mixes both audio tracks together. If you want only your voice, mute the original track in an editor before merging.

What format should my voiceover file be?

MP3 or WAV files work best. Record with a decent microphone and minimal background noise for a clean result.

Can I adjust the volume balance between voice and original audio?

You can pre-adjust the volume of either file in a free audio editor before combining them in the tool.

Is there a length limit for the voiceover?

The voiceover can be any length. If it is longer than the video, the extra audio will be cut off at the video's end.

Can I use this for reaction videos?

Absolutely. Download the Reel, record your live reaction as audio, and merge them for a quick reaction clip ready to post.

Can I record and add the voiceover entirely from my phone?

Yes. Record your voiceover using your phone's voice recorder app, then use ReelTools' Add Audio to Video tool in your mobile browser to merge it with the downloaded Reel.

Does this require any paid editing software?

No. ReelTools handles the audio merging for free. You only need a basic voice recorder (built into every phone) and a browser.

What's the best way to record a clean voiceover on a phone?

Use your phone's voice memo app in a quiet room. Hold the phone about 6 inches from your mouth and speak clearly. Even phone microphones produce surprisingly good results in low-noise environments.
