Adjusting Music On Hold/Custom Recording Sound Levels

Introduction

This How-To covers adjusting the sound levels of music on hold/custom recordings for the Avaya IP Office/ShoreTel systems, but can be applied to other systems if they support the same file settings or if you know the correct settings required.

Steps:

1: Download Audacity

Download the free audio editor “Audacity” from the below link:

http://audacity.sourceforge.net/

2: Open Music File In Audacity

Right click on your audio file and select “Open with”, choosing Audacity from the list of programs to open the file with.

3: Adjust Track Volume

The average human can only distinguish volume changes of around 3 decibels (dB), so if you need to adjust the volume of your music on hold/custom recording files, it would be best to increase/decrease in 3 dB increments.

To do this in Audacity, on the left hand side of the audio track there should a volume bar which can be increased/decreased in levels of 1 dB, ranging from -36 dB up to +36 dB.

4: Save The Changes

After adjusting the volume, save the file with the necessary settings for your system.

For reference, the following audio settings are supported on Avaya/ShoreTel systems:

Avaya:
PCM/Uncompressed, 16-bit, 8 kHz, Mono

ShoreTel:
µ-law, 8-bit, 8 kHz, 16 kHz, Mono
α-law, 8-bit, 8 kHz, 16 kHz, Mono
16-bit, 8 kHz, Mono
16-bit, 16 kHz, Mono

All files must be in .WAV format. Files such as .mp3 are not supported.

Conclusion

All that’s left to do after saving is to copy the files to their relevant folders/locations and check to see whether the volume levels are at a more satisfactory level than before.

Converting Music On Hold/Custom Recordings

Introduction

This How-To covers converting music on hold/custom recordings into the correct format for the Avaya IP Office/ShoreTel systems, but can be applied to other systems if they support the same file settings or if you know the correct settings required.
