Essential Interview Recording Tips on a Cell Phone

1. Choose the Right Recording App

While most smartphones have a default voice memo app, you might want to explore dedicated audio recording apps that offer higher quality and more features for interviews.

Recommended Recording Apps:

• Rev Voice Recorder: This app is designed for high-quality recording and transcription. It offers an easy interface and clear audio capture, making it ideal for interviews.

• Voice Memos (iPhone): For iPhone users, the built-in Voice Memos app is an effective solution for basic recording, with options to trim, share, and store recordings in the cloud.

• Otter.ai: Otter is a popular app for both recording and transcribing interviews. It records the conversation and provides automatic transcripts in real time.

• Easy Voice Recorder: Available for Android, this app allows you to record in various audio formats and store files directly in Google Drive or Dropbox.

2. Position Your Phone Correctly

Where you place your phone during the interview is critical for capturing clear audio. Follow these tips to ensure optimal sound quality:

• Keep the Phone Close to the Speaker: Position your phone as close to the person speaking as possible, ideally 6-12 inches away. This reduces background noise and captures clear audio.

• Avoid Obstructions: Ensure nothing is blocking your phone’s microphone, such as a case or clothing. The microphone should have a direct line to the speaker’s voice.

• Use a Tripod or Stand: Holding the phone during the entire interview can lead to unwanted noise from movement. Use a small tripod or phone stand to keep the device stable and reduce handling noise.

3. Minimize Background Noise

Recording in a noisy environment can make it challenging to hear the interviewee clearly. Here’s how you can minimize background noise:

• Choose a Quiet Location: Whenever possible, pick a quiet place for the interview, away from traffic, crowds, or loud machinery.

• Use External Microphones: Consider using an external microphone that plugs into your phone’s headphone jack or charging port. Lavalier (lapel) mics, shotgun mics, or Bluetooth mics can significantly improve audio quality.

• Enable Airplane Mode: Put your phone in airplane mode to avoid interruptions from incoming calls or notifications that can disrupt your recording.

4. Test the Audio Before You Start

Before diving into the full interview, take a minute to test the recording to ensure that the audio levels are adequate and the phone is positioned correctly. Playback the test recording to verify that the sound is clear and there are no technical issues.

5. Record in High-Quality Audio Formats

Many recording apps give you the option to choose the audio format and quality. Opt for high-quality audio formats like WAV or FLAC if you want the best sound, especially if you plan to transcribe the interview later. Even though MP3 files are smaller, they may sacrifice some sound quality, which could be important for longer interviews.

6. Keep an Eye on Battery and Storage

Recording interviews can quickly drain your phone’s battery and eat up storage space, especially if you’re capturing high-quality audio. Before the interview:

• Charge Your Phone: Make sure your phone is fully charged or connected to a power source during long recordings.

• Free Up Storage: Ensure there is enough storage on your phone to handle large audio files, particularly if you’re recording in high-quality formats.
