How to Record ASMR Whisper With a Phone: Placement, Noise Control, Levels and a Simple Edit
By Aria Wilde · updated 2026-11-07 · 5 min read
A phone is a good place to start. Modern phones have decent microphones, and a quiet whisper recorded close to the microphone can sound surprisingly good. The main difficulty is noise: the room, the phone and your own breath. Here is how to keep them under control.
Prepare the phone
- Airplane mode. Stops notifications and radio interference.
- Do Not Disturb. Make sure no sound, vibration or flash will occur.
- Free storage. Make sure you have space for a long file.
- Charge or plug in. A warm phone can hum less than a low battery.
- Clean the microphone hole. A bit of lint can muffle sound.
Use the voice recorder or a recording app that saves in high quality. If the app allows it, choose a lossless or high-bitrate format.
Where to place the phone
The microphone is usually at the bottom edge, sometimes with a second at the top. Find it by speaking and watching the level meter.
- Place the phone a hand's width (10-15 cm) from your mouth, slightly to the side so breath does not blow directly into it.
- Stand it on a folded towel or pillow to stop vibrations.
- Point the microphone at your mouth but angled away from the airflow.
- Keep it in place; do not hold it, since handling noise is loud.
For a left-right effect, record in two passes: the first with the phone on the left, the second on the right, and mix them. Or move your head slowly so the voice drifts across the stereo field, if your phone records in stereo.
Control the noise
- Pick a room with soft furnishings and no echo; a bed with a duvet is great.
- Close windows, switch off fans and fridges, and tell others in the house.
- Record when the building is quiet.
- Avoid wearing noisy fabric; take off jewellery.
- Record ten seconds of silence at the start to use as a noise sample.

Set levels
Phones often apply automatic gain, which raises background hiss during quiet parts. If your app allows it, switch off automatic gain control. Whisper at your performance volume and look at the meter: you want peaks in the middle, not the top. If your phone has no meter, record a test, play it back with headphones, and adjust distance rather than gain.
Whisper technique
Whisper with relaxed breath and clear consonants. Keep the volume low and the pace slow. Turn your head slightly for inhales. Do not whisper from the throat; use the lips and tongue. If you get dry mouth, sip water between takes.
Use a short script to practise, for instance the opening lines of ASMR roleplay girlfriend script for sleep, and make three takes. Listen to all three before choosing.
A simple edit
Use a free editor on a phone or computer.
- Trim the start and end.
- Cut clicks, coughs and bumps.
- Apply noise reduction lightly (6-12 dB) using your silence sample.
- Normalise to a comfortable level, or compress gently.
- Add a fade-in and fade-out.
- Listen on headphones at night volume.
Save an original copy before editing, and export a final version in a high-quality format.
Using headphones with a phone
Wired headphones let you monitor while recording, but a headphone cable can rub against your clothing and make noise. Clip the cable or tuck it under a layer of fabric. Wireless headphones add delay and may switch the phone microphone to the headset one, so check which microphone the app is using before you start.
Choosing a recording app
Look for an app that lets you pick the file format and shows a level meter. Avoid apps that add effects or automatic noise cancelling to your recording, because they remove the very soft sounds you want. If your phone only offers a basic recorder, test it for hiss in a quiet room before committing to a long take.
Making a short test session
Before any real project, do a five-minute test. Record: a few whispered sentences, five seconds of fingertip tapping, a soft brush on fabric and ten seconds of silence. Listen on headphones and decide whether the voice, the sounds and the quiet are clean. Fix the largest problem first, record again, and compare. Doing this once saves you from recording a long track and discovering a hum halfway through.
Troubleshooting
| Problem | Fix |
|---|---|
| Hiss | Move closer, reduce gain, use noise reduction lightly |
| Pops on P and B | Angle the phone, whisper more softly, use a foam cover |
| Echo | Hang a blanket, record in a smaller room |
| Wind-like breath | Turn your head, increase distance |
| Phone hum | Airplane mode, unplug charger |
Recording a longer session
For a track of ten minutes or more, plan breaks. Record in sections of two or three minutes, pause, sip water and begin the next section with the same distance and posture. Say a short marker at the start of each section ("section two") in a very quiet voice, or note the timing on paper; it makes editing faster because you can see where each take begins. Put a sticky note on the wall at eye level with the opening line of your script, so you keep the same head position and do not drift toward or away from the microphone.
Protecting the phone and your sound
Rest the phone on a soft surface and keep your hands off it during the take. If the screen lights, cover it with a cloth. Keep the case on if it reduces rattling. Do not place the phone on a hard table next to a laptop or speaker, since fans and electronics can add a faint hum. After the session, listen to the first and last minute of the file: if the quality has drifted, the phone may have warmed up or your seating may have shifted.
Next steps
When you outgrow the phone, a USB microphone with a pop filter is the usual upgrade. Until then, keep practising and listen to your recordings on different headphones.

Frequently asked questions
Can I record ASMR with just a phone?
Yes. Use airplane mode, a quiet room, close microphone placement and light editing. Many creators start this way.
How far should the phone be from my mouth?
About a hand's width, slightly to the side so breath does not hit the microphone directly.
How do I reduce background noise?
Choose a quiet, soft room, switch off fans, record at quiet times and use light noise reduction with a silence sample.
Should I turn off automatic gain?
If the app allows, yes. It prevents the hiss from rising during quiet moments.
What free app can I use to edit?
Any simple audio editor will do: trim, reduce noise lightly, normalise and fade. Keep your original file.
