Converting Audio Files to WAV Format for Optimal 3CX Performance

When configuring your 3CX phone system, you might need to upload custom audio prompts for Interactive Voice Response (IVR) menus, call queues, or music on hold. 3CX requires these audio files to be in a specific WAV format to ensure compatibility and proper playback. This article will guide you through the process of converting your audio files to the required WAV format.

Why Convert to WAV?

3CX uses WAV files with specific characteristics for system prompts:

• Format: WAV
• Channel: Mono
• Bit Rate: 8 kHz
• Sampling: 16 bit

Using audio files that don't meet these specifications can lead to playback issues or system errors. Converting your audio files ensures they are compatible with the 3CX system.

Methods for Converting Audio Files

There are two primary methods for converting audio files to the required WAV format:

1. Using the 3CX Online Audio Converter
2. Manually converting the audio file using audio editing software like Audacity

Option 1: 3CX Online Audio Converter

The 3CX Online Audio Converter offers a quick and easy way to convert your audio files.

Steps:

1. Navigate to the 3CX Online Audio Converter.
2. Drag and drop your audio file into the upload area, or click the image to select a file from your computer.
3. Complete the CAPTCHA verification if prompted.
4. Once the conversion is complete, click "Download" to save the converted WAV file.

Option 2: Manual Conversion Using Audacity

For more control over the conversion process, you can use a free audio editing software like Audacity.

Steps:

1. Download and Install Audacity: Download Audacity from the Audacity website and install it on your computer.

   • File Name: Enter a name for your converted file, using only Latin characters.
   • Save as type: Select "WAV (Microsoft) signed 16-bit PCM".
