Recording and Modifying WAV Audio Files

"WAV" (pronounced "wave") files are pre-recorded audio files. WAV files used with Active Call Center must have a specific format in order to work. The instructions below show how to record and modify wave files that can be used with Active Call Center.

Standard Microsoft Windows installations include Microsoft Sound Recorder, a utility used for creating and modifying WAV files.

Recording WAV Files for Use with Active Call Center

From the Windows taskbar, choose Start ... Programs ... Accessories ... Entertainment ... Sound Recorder.

Use Sound Recorder with your microphone to record some audio. For help, refer to the Sound Recorder help file.

When finished recording, choose from the Sound Recorder menu bar: File ... Save As.

At the "Save As" window, click the Change button near the bottom next to the file format.

For playback on most modems and telephony cards (including Brooktrout) set the Format to "PCM" and set the Attributes to "8,000 Hz, 16 Bit, Mono". For playback on most Dialogic cards, set the set the Format to "PCM" and set the Attributes to "11,025 Hz, 8 Bit, Mono".

Click OK.

Enter a file name and click Save.

Editing and Amplifying Recorded Audio

Start Sound Recorder as described above and open the file to modify.

From the Sound Recorder menu bar, choose options under the Edit or Effects menus. Amplification options are under the Effects menu.

Play the modified audio to make sure it has the desired properties.

When finished editing audio, choose from the Sound Recorder menu bar: File ... Save As.

At the "Save As" window, click the Change button near the bottom next to the file format.

For playback on most modems and telephony cards (including Brooktrout) set the Format to "PCM" and set the Attributes to "8,000 Hz, 16 Bit, Mono". For playback on most Dialogic cards, set the set the Format to "PCM" and set the Attributes to "11,025 Hz, 8 Bit, Mono".

Enter a file name and click Save.

Professional Voice Recordings

When a professional sounding voice is a requirement, consider hiring a voice professional. Some websites to try include:

Be sure to let them know what format PCM audio files you will need. You may want to have them record at a higher quality and then convert the audio to the lower quality format (that way you'll have the higher quality files if you ever need them).
