Many viewers will keep watching a slightly soft video, but they leave quickly if they cannot hear you clearly. Hiss, echo, a voice that is too quiet, or game sound drowning your explanation — these are the most common reasons a good tutorial feels amateur. The good news: most ways to improve audio quality in video happen before and during recording, and they cost nothing.
This guide covers the three basics — levels, noise and mixing — for screen recordings with a microphone and system sound.
Basic 1: get healthy voice levels
"Level" means how loud your voice is in the recording. Too low, and viewers turn their volume all the way up, then get blasted by the next video. Too high, and the sound "clips" — it becomes harsh and crackly, and that damage cannot be fully fixed later.
How to get it right
- Do a short test. Say a sentence at your normal teaching volume and watch the level meter.
- Aim for the middle-to-upper range on loud words, never hitting the very top.
- Keep a steady distance from the mic. Moving closer and further changes the level constantly.
- Speak with energy rather than shouting. Clear and confident is louder than you think; our tips on speaking confidently on video help.
Basic 2: reduce noise at the source
Noise is anything you do not want: fans, traffic, a generator, a TV in the next room, hum from a charger. Noise-reduction tools exist, but they often make voices sound watery. It is far better to record less noise in the first place.
- Pick a quiet time. Early morning or late evening is often calmer in busy cities.
- Turn off the ceiling fan during short takes if you can. Fans are one of the most common sources of steady noise.
- Use a soft room. Curtains, a bed, a sofa and a rug absorb echo. Bare tiled rooms make voices sound hollow.
- Get the mic closer. A simple wired or wireless earphone mic near your mouth usually beats the phone's built-in mic at arm's length.
- Silence notifications so pings and vibrations are not recorded. Our guide on recording without notifications shows how.
Handling noise you cannot avoid
If some background noise remains, keep it steady rather than changing. A steady low hum is less distracting than random sounds. Light background music can also mask a little room noise — see background music for tutorials.
Basic 3: mix your voice with system sound
When you record internal audio (the sound from apps, videos or games) along with your mic, you have two sources fighting for attention. The rule is simple: your voice comes first.
| Video type | Voice | System sound |
|---|---|---|
| App tutorial | Main | Low, or off |
| Product demo with sound effects | Main | Noticeable but clearly lower |
| Game clip with commentary | Clear on top | Present, lower while you talk |
| Showing a video or music feature | Pause talking | Full while it plays |
- Lower the in-app volume before recording so it does not overpower you.
- Stop talking when the app's sound is the point, then continue.
- Avoid copyrighted music playing in the background of other apps; it can cause problems when you upload.

Fixing problems after recording
Sometimes you only notice an audio problem later. A few realistic options:
- Voice a little too quiet: raising the volume in an editor usually works, as long as the recording is not full of noise.
- A loud bang or ping in one spot: cut that moment, or lower the volume just there.
- Clipped, crackly voice or heavy echo: these are very hard to repair. For short tutorials, re-recording the narration is often faster than fighting the problem.
That is why checks before recording are worth so much more than fixes afterwards.
A five-minute pre-recording audio check
- Quiet room, fan off, notifications silenced.
- Mic close and steady.
- Test sentence, check the level meter.
- In-app volume lowered.
- Ten-second test recording, played back with earphones.
Listening on earphones matters: phone speakers hide hiss and hum that viewers with headphones will hear clearly.
Audio in Cinematic Recorder
Cinematic Recorder records your microphone and internal/system audio together (system audio on Android 10+), and shows a live mic level meter so you can see healthy levels and spot a muted mic before you waste a take. Floating controls let you pause if a noise interrupts, then resume. Cutting the silent pauses is a tick-box in the editor's AI sheet; automatic filler-word removal is still coming soon. See the recording features.
FAQ
What is the easiest way to improve audio quality in video?
Move the mic closer to your mouth and record in a quiet, soft room. Those two changes usually make the biggest difference.
How loud should my voice be in a recording?
Loud enough that the meter sits in the middle-to-upper range on normal speech, without ever hitting the maximum.
Should I use noise reduction?
Lightly, if at all. Strong noise reduction can make voices sound unnatural. Reducing noise at the source works better.
Why is the app sound louder than my voice?
The in-app volume was too high during recording. Lower it before you start and keep your mic close.
Clear sound is the quiet foundation of every good tutorial. Fix your levels, reduce noise before you hit record, keep your voice on top of the mix — and viewers will stay to hear what you have to teach.
