Quick answer
Import the interview recording.
Listen to the loudest answer first.
Raise gain gradually.
Use EQ to reduce mud and bring speech forward.
Export when both speakers remain understandable.
Why interviews get tricky
One speaker may be near the phone while the other is farther away. That unevenness makes it easy to over-boost the stronger voice while still struggling with the weaker one.
What the best result sounds like
The finished file should feel easier to follow, not just louder. A good export keeps the conversation natural and avoids making breaths, hiss, or room reflections too distracting.
Best use cases
Journalism interviews
Research conversations
Remote-style in-person interviews
Reference clips for transcription
FAQ
Related questions.
What is the best app for interview recordings on iPhone?
The best app makes interview audio louder while keeping both speakers understandable and avoiding unnecessary harshness.
Can it help when one person is much quieter?
It can improve the overall file, but strong differences between speakers still require careful listening and moderate settings.
Does interview audio need EQ as well as volume?
Often yes. A light EQ adjustment can improve speech clarity more safely than a heavy boost alone.
Volume & Bass Booster processes audio and video imported into the app. It cannot override iOS system volume for other apps. Use comfortable listening levels to protect your hearing.
