MIDI and MP3 are completely incomparable. MIDI uses whatever synthesizer you have to render the extremely-low-bitrate sound you send to it.
MP3 takes what you did, be it from MIDI or Bosendorfer, and figures out what parts are audible and what parts aren't, and works on from there.
As for the telephone company are you sue they still employ that audio bandwidth in the strictest sense?
For everything except cell phones, it's now 200-3600 in a lot of applications, but that is not a significant change.
Low bit rate cell phones may be more bandwidth limited, depending on what you're using, where, and what you're listening to.
Their focus is voice and only voice. Everything else is noise and requires no bandwidth. Like when you're talking to someone in a car with the radio on. The radio is completely unintelligible if it has no vocal content.
Um, you're confuting so many different issues I hardly know where to start. Yes, I know what Telcos care about, I worked for one for 26 years, after all, even if I did work in a completely different area, that of full-bandwidth audio. Telcos care about very few things at this point: Cheap service cost, low bandwidth, and sales. Service used to be an issue, but is no longer.
