Tips for recording clean audio with any equipment

Whether you’re recording on your phone or using an audio recorder, test your microphone before you begin, and make sure you have sufficient battery for the interview.

Quiet

Choose a quiet environment to record in. If your surroundings are really noisy, try to record at a quieter time or on your bed under a sheet.

If you're hearing noise in your recording, the most common white-noise culprits are refrigerators, air conditioners/heaters, overhead lights (only if they buzz/hum), and open windows.

Cozy

You might notice that singing in your shower sounds different than singing in your living room. Sound has the tendency to bounce around and each room will have a surprisingly different tone to it, so if you have several choices, we'd recommend a test recording in each location, just to see if anything stands out about one or another. Look for a room that has the least reflective surfaces.

Close

The easiest way to improve recording quality is to get close to your microphone. This means using headphones with a built in microphone, holding your phone closer to your face, or getting closer to your laptop or recording device.



Remember...

  • Capture everything…you can always edit later! Before you go out on interviews or field recording sessions, think a little about what you want your final product to sound like. Audio storytelling is most compelling when we hear “primary sources” – the people involved, underscored by the sounds we would hear in the world. Record everything you think might be useful, including your subjects introducing themselves, any outtakes, etc. It’s easier to leave things on the cutting room floor than to go out recording again!

  • Audio comes in a variety of formats, which range from “lossless” to highly compressed. As with video and still images, it’s always possible to compress or downsize files, but it’s not possible to raise the quality of a compressed file. So, as a rule, you want to record in high quality (such as WAV or Apple’s m4a format), store your working files in high quality formats, and only export them to mp3 at the end of the process.

Recording with your smartphone

  1. Choose your audio recording application: Most smartphone platforms come with an application that can be used for recording voice memos. These applications will allow you to record and trim simple audio recordings, but are limited in options for manual settings while recording.

Some free alternatives to these apps are:

Voice Record Pro (iOS only)

Titanium Recorder (Android only)


  1. Microphone placement: In order to guarantee the highest quality of audio in your recording, it is important to pay attention to the proximity between your microphone and your subject. When recording a group discussion it is important to arrange the participants so that they are equidistant from the recording device, and if possible, try to avoid areas with a lot of background noise (fan, laptop, open window or other groups of people). Choosing a location with a quiet atmosphere can also help to make sure you have a clear capture of everyone’s voice. However, some background noise is okay - you also want to keep the conversation feeling natural and not too staged - as long as you can hear all of the participants in the conversation. Other tips for increasing the quality of an audio recording are to remove your phone from its case, and limiting movement of your phone or other objects around it (for example, papers on a table).


  1. Test your recording: You won’t be able to monitor your audio while recording, so it is important to test your recording prior to capturing anything that you plan to use later. Wear headphones while listening to playback to ensure the best quality while you are monitoring your test recording. Listen for things like background noise (HVAC, traffic, other people’s conversations) and to make sure that your microphone is picking up your subject at an appropriate level.


  1. Start early, stop late: Make sure to begin your recording prior to the start of a discussion, and allow it to run even when the discussion seems to be slowing down or has stopped. It is hard to know exactly which segment of a discussion will stand out as “the best” part, but you can ensure you don’t miss it by capturing everything.


  1. Name your recording: Even if you don’t have a lot of audio files stored on your phone, make sure to name your recordings after you have finished. This will help keep files organized throughout the uploading and transcription process, and can help you to make sure nothing gets deleted by accident.


Recording with an Audio Recorder

The Learning Lab has a few other pieces of equipment that might be helpful to capture the best quality of audio possible. Zoom H1 audio recorders that are available for checkout at the Learning Lab are very easy to use audio recorders that can be used as an alternative to a cell phone, which can help address concerns around available hard drive space, or other challenges with using a personal device. Contact Casey Cann for equipment availability and see any of the Learning Lab staff when picking up the equipment for a quick introduction to the recorder.

If you need equipment *now* and it's a weekend day, check out the Harvard Tech Loan program. Find more resources here.
