Appendix F: All Things Audio

The information within this appendix deals with all details regarding the formatting, playback, and the recording of audio files within your application. As most of us realize that a professional-sounding application should rely more strongly upon 'real human' audio files rather than Text-To-Speech, the information here should serve as your guidebook when considering the addition of audio within your application.

In addition, we have an entire subsection devoted to how to record and store audio files from your application, as well as several instances of working samples that you can plug into your existing code and save time. Here at Voxeo, we work hard, so you can slack on the job.

Overview

Audio Formats and backup TTS: If you want to use a pre-recorded audio file in your application, then you will definitely want to read this. Detailing the allowable audio formats, and the methods of using backup text-to-speech, the information contained within this section will prove invaluable to anyone using audio files within their applications.

The Voxeo Audio Library: Perhaps you'd like to swipe some of our own professionally recorded audio files? Be our guest! We have a bevy of standard tones and phrases that you will find extraordinarily useful when adding the final polish to your application...and they are all free!

Audio Tools and Links: Want to change the formats of your files for better quality? Find the cutting-edge freeware audio tools that are taking the Voxeo office by storm on this page! And believe me, you *don't* want to record your own sound files for your production application, you'll want to hire a pro. Which is why, as a Special Bonus Addition, you will also find some links on where to find quality audio talent for your application contained in this subsection.

Recording Audio: A Primer: Using the <record> element is pretty cool, but eventually you'll want to save those recordings somehow. This section covers the caveats to recording audio, and provides several instances of sample code showing you how you can email or FTP that recorded file for safekeeping. Don't bother thanking us, just throw money......
