How to Transcribe Interviews Recorded on a Phone
Many people record interviews on their phones today. The process feels simple, fast, and budget-friendly. But poor audio can make transcription slow and stressful.
This guide shows you how to capture clear audio, pick the right file format, and follow smart steps for smooth transcription.
Why Phone Recordings Matter
Your phone is always with you, so it is perfect for interviews. Modern phones record high-quality audio and store big files with ease.
Still, your results depend on how you set up the recording and how you handle the file later.
Set Up Your Phone for Better Audio
Good sound starts before you press Record. Small changes can give you a clearer transcription.
Choose the Right Spot
Location affects the sound more than your phone does. Pick a quiet and simple space.
- Find a room with little echo.
- Turn off fans, TVs, and alerts.
- Pick a place where both people sit close.
Hold the Phone the Right Way
Your phone’s mic sits near the bottom. Make sure it faces the speaker.
- Keep the mic 6–12 inches from the speaker’s mouth.
- Do not rub the phone with your hand.
- Do not set the phone on loud or shaky surfaces.
Use an External Mic
An external mic boosts sound quality right away. It also cuts background noise.
- Lavalier mics clip to a shirt and record clean voices.
- Shotgun mics target sound from one direction.
- USB-C and Lightning mics plug right into most phones.
Pick a Good Recording App
Default apps work fine, but some apps offer more control. Choose one that fits your needs.
- Look for apps that support WAV or high-quality MP3.
- Pick apps that show volume levels.
- Check for features like noise reduction or cloud backup.
Best File Formats for Transcription
Your choice of file format can change quality and file size. Some formats are better for detailed transcription.
WAV
WAV gives you the best quality. It uses no compression.
- Ideal for long interviews.

MP3
MP3 gives smaller files while keeping good quality. Many people use it daily.
