7 Tips for Better Audio Recordings in Interviews

Introduction

The quality of your audio recording is crucial for AI transcription accuracy. With these 7 tips, you’ll achieve professional results that AI Reporter can process optimally.

1. Choose a Quiet Environment

Problem: Background noise drastically reduces transcription accuracy.

Solution:

• 🔇 Close windows (street noise)
• 📱 Phones on silent
• ❄️ Turn off AC/heating
• 🚪 “Do not disturb” sign

Tip: For outdoor recordings, use a windscreen for your microphone!

2. Use the Right Microphone

Recommendations by Budget:

Budget (< $50):

• Lavalier microphone (clip-on)
• Smartphone with external mic
• USB microphone for laptop

Mid-Range ($50-200):

• Zoom H1n Handy Recorder
• Rode SmartLav+ (for smartphones)
• Blue Yeti USB microphone

Professional ($200+):

• Zoom H5/H6
• Shure SM7B
• Rode Podcaster

3. Optimal Distance to Microphone

Rule of Thumb: 6-12 inches (15-30 cm) distance

• ❌ Too close: Plosives (P, B, T) distort
• ❌ Too far: Too quiet, many background noises
• ✅ Optimal: Hand’s width distance

For lavalier microphones: Attach 6-8 inches below the mouth.

4. Audio Format & Quality

Recommended Settings:

Format:      MP3 or WAV
Bitrate:     128 kbps (minimum), 256 kbps (optimal)
Sample Rate: 44.1 kHz or 48 kHz
Mono/Stereo: Mono sufficient for speech

Why? Higher quality = better transcription, but larger files.

AI Reporter supports: MP3, WAV, M4A, FLAC, OGG (max. 1 GB)

5. Improve Speaker Identification

For multi-speaker interviews:

• 🎙️ Each speaker has own microphone (ideal)
• 📍 Position speakers far apart
• 🗣️ At start: “My name is [X]” (helps the AI)
• ⏸️ Don’t speak simultaneously

Tip: For Zoom calls, record separate audio tracks (Zoom Premium feature).

6. Make a Test Recording

Before every important interview:

1. Make 30-second test recording
2. Play back and check quality
3. Adjust levels (not too quiet, not clipping)
4. Upload to AI Reporter and verify quality

Level Rule: Audio should be at -12 dB to -6 dB (not in the red zone).

7. Backup Recording

Murphy’s Law: What can go wrong, will go wrong.

Best Practice:

• 📱 Smartphone as backup recorder
• 💾 Two separate recording devices
• ☁️ Save immediately after interview (cloud, USB stick)

Personal Story: A journalist lost a 2-hour interview due to a corrupted SD card. His smartphone backup saved the story!

Bonus: AI Reporter Context Optimization

Give AI Reporter context for better results:

Context Example:
"Interview with Dr. Maria Schmidt, climate researcher at PIK Potsdam, 
about the current IPCC report. Topics: climate change, CO2 emissions, 
energy transition."

Result: Better recognition of technical terms and person names.
