The first thing you want to do is determine
how much data you intend to load on the
Envoy S.
We call this ‘Runtime’

If you have your own custom message that
you would like to load (or combine with
other standard messages)
check the runtime of your files.
You can use this tool to check runtime:

The 4GB Envoy S unit can hold approximately
3400 MB of data.
The 8GB Envoy S unit can hold approximately
7400 MB of data.
The graphs in the next 2 slides show the
available runtimes for 3400 MB & 7400MB
at different compression levels.

For example, using a mid-range setting
(22kHz, Mono, 32kpbs) will allow you to load over
200 hours onto the Envoy S 4GB.

Notes about compression:
Lower compression rates = Less runtime but Higher Quality
Higher compression rates = More runtime but Lower Quality
You can experiment with the settings (sample rate / bitrate)
but only go lower if your original files are HIGH QUALITY!!!
(please contact Ed Zagofsky [e-mail] or by
Skype: ezagofsky, for more help on audio compression options)
