Adobe Presenter

Last updated 6/26/2014

Have a glass of water nearby so you can avoid “dry mouth.” Before recording, turn away from the microphone, take a

deep breath, exhale, take another deep breath, open your mouth, turn back toward the microphone, and start speaking.

By doing so, you can eliminate breathing and lip-smacking sounds frequently recorded at the beginning of audio tracks.

Speak slowly and carefully. You may feel that you are speaking artificially slowly, but you can adjust the speed later by

using your audio recording software. Finally, keep in mind that you don’t have to get everything right the first time. You

can listen and evaluate each recording and rerecord, if necessary.

Editing sound

Editing sound is like editing text. Listen carefully to your recording, delete any extraneous sounds, and then use the

options available in your software to polish the sound. Add any music or sound effects you require, but make sure to

save your audio track in the correct format (mp3 or WAV).

Reviewing the presentation

After you have added the audio to the presentation, listen to it again. Finally, it helps to ask others to preview the

presentation file. If necessary, you can edit the audio again, on a per-slide basis.

About audio recording equipment

Having the right audio equipment makes a significant difference in the quality of recorded audio. Surprisingly, basic

audio equipment can be relatively inexpensive; your equipment could include some if not all of the following:

Computer with a sound card The sound card installed in your computer acts as a digital recorder for audio.

Microphone If possible, avoid using the internal microphone that comes with most computers. Use a professional-

quality microphone cable and a stand to hold the microphone while you are recording.

Microphone preamplifier A preamplifier boosts the signal of the microphone. The microphone input of your

computer’s sound card probably includes a preamplifier, but it’s most likely a poor quality one. When purchasing a

preamplifier, you can choose a small mixer or a stand-alone version. Mixers let you connect several microphones and

devices to one location, and you can adjust their volumes independently. Stand-alone preamplifiers can be better than

mixers at filtering out unwanted noises.

Speakers The speakers that came with your computer are probably good enough for listening to any audio you record.

For best results, check the specifications of your speakers and use the highest-quality speakers possible.

In Microsoft Windows operating systems, you can usually find speaker (sound) settings by clicking Start in the lower-

left corner and selecting Settings > Control Panel > Sounds.

Recording software A wide range of recording software is available, including Adobe Audition®. Important software

features include editing capabilities (to fix mistakes), music and sound-effect options, and the capability to create the

file format you require (such as mp3 or WAV).

Recording area You need a quiet place to record. Try closing doors, turning off any unnecessary computer equipment,

turning off or lowering lights that might be making noise, and turning off phone ringers, beepers, and pagers. Also, tell

coworkers that recording is in progress.

Set audio recording quality

Audio files present the common challenge of balancing quality against size. The higher the sound quality, the larger the

file size. When working with audio, think of your users’ connection speed. In the best development case, experiment

to find the optimal balance between sound quality and file size for your users.
