Is the expected sound quality specified?
Precisions
The sounds broadcast by the service are characterized by their duration, the number of repetitions, the quality of the sound and finally the type of encoding (Codec) used. Actions on each of these points will reduce the impact of sound files both in the transfer and the volume of the files. Some highly compressed codecs significantly reduce the volume of data for the same quality, but encoding / decoding these formats can require a lot of processing resources, which greatly diminishes the overall benefit from a Sustainable IT point of view.
