Audio Checklist
You may have a good clear speaking voice, this didn’t mean that it sounded good as digital audio.
Learning content that may look great and function flawlessly can be completely ruined by poor audio recording.
The Microphone
Use a good quality USB microphone, or use a noise-cancelling headset with microphone. You don’t need to spend big, but take the time to do some
market research.
Test and adjust your microphone each time before recording. It should sit at the same height as your nose, or slightly above your mouth if you’re using a
headset.
Use a pop filter on your microphone if possible.
Before You Record – Pre Production
Make sure your recording environment is quiet and free from background noise (check air vents, fluorescent lights, or computer fans).
Record in a room with carpeting, padded furniture, and the fewest hard/flat surfaces possible. Place your microphone in an isolation box, or put a towel
on your desk under the microphone to dampen reflected sound waves.
Turn off all electronics that might interrupt your narration (cell phones, email notifications, etc.).
Do an ambient background noise recording with no speech to identify if any background noises will be intrusive on playback.
Write and rehearse a script
Know your audience. Write for the people most likely to be listening.
Write in a conversational tone, and in your own words.
Avoid short forms or abbreviations in the script so as not to trip up the narrator (you!).
Identify and practice any acronyms or difficult-to-pronounce words.
Determine a speaking tone/style for your narration, and identify words that might need special emphasis.
Write voice directions into your script (e.g., “spoken cheerfully” or “pause dramatically”).
Practice speaking your script out loud to eliminate pauses/hesitations and to improve flow.
Audio Checklist
During production
Sit up straight when you record, or try standing when possible for better breathing and audio.
Be animated and smile while talking. People will hear the enthusiasm in your voice.
Use a mirror while practicing, and imagine you are speaking to another person.
Listen to yourself periodically, and take notes on your likes/dislikes (phrasing, intonation, mouth position, etc.). Keep these notes handy for subsequent
recording sessions.
Let someone else listen to your recording early on. Choose someone you trust to give you honest feedback.
Experiment with the best time of day for your own voice and try to record at the same time of day for consistency.
Don’t fidget when you record. It may interfere with your narration and force you to have to re-record.
Don’t forget to breathe…
… But pay attention to your breathing. Loud inhaling or exhaling sounds are irritating for the listener, though subtle natural breaths are okay.
Take care of your voice. Have some water, herbal tea with honey, lemon juice, or throat lozenges handy, and take breaks if your voice starts to feel
strained.
Got a cold? Take a break. Your “sick voice” will be hard to reproduce if you need to redo narration later.
Practice good vocal techniques like warming up your voice, watching your speaking speed, and practicing good pronunciation and intonation.
Know when it’s “good enough”. Don’t spend hours recording and re-recording one sentence.
Post Production
Record multiple takes. People rarely nail a recording on the first take, so listen to the playback, and choose the best. What may take you a minute to rerecord may take someone far longer to fix in post-production.
If you make a mistake in a longer segment, keep the recording going and simply restart the narration from the beginning of the phrase or sentence. The
unwanted part can be edited out later.
Mark your mistakes. For mistakes you can’t fix in a new take, clap or blow loudly into the microphone as a reminder. This creates a spike in the audio
waveform and is easy to spot later.
Remember to remove your outtakes. Handing over a clean version of your recordings to your designer or producer will make life much easier for the both
of you.
