Technology Is Gonna Do What?

The telephone has been around almost 150 years, since 1870. By 1879, telephone service subscribers began to be identified by their phone numbers, not by their names and by 1918 a million telephones were in service just in the USA. In 1962, Telestar, the first communications satellite was launched. In 1973, the beginning of the end of telephone communications arrived when Martin Cooper developed the first handheld mobile telephone. The first analog cell phone system went into service in Japan in 1979. In the 1990’s, cell phones began the switch to digital and there are hundreds of millions of people now frustrated by the awful sound of low-fidelity (at best an 8bit/8kHz sample rate, 200-3.2kHz bandwidth, 64kbs data compression) digital cell phone conversations and miscommunication created by lousy digital connections.

In fact, according to an Atlantic Magazine article "Don't Hate the Phone Call, Hate the Phone" a whole generation, Millennials, have been diagnosed with a “kind of telephoniphobia” regarding voice telephone communications. Now that half of Americans under 35 use cell phones exclusively, “the intrinsic unreliability of the cellular network has become internalized as a property of telephony.” It isn’t. It’s a property of fuckin’ cell phones and I absolutely hate the damn things. I hate getting calls from people on their cell phones. I hate calling people who I know will answer my call on their cell phone. Between the distortion, the Auto-Tune-like Mr. Roboto voices, and the forced long pauses while we try to determine if there is still a usable connection (on their side) I just assume that at least 3/4 of the things that were said were misunderstood or not heard at all.

I have stopped listening to audio fidelity complaints from people who tolerate cell phones. This is not an anti-digital rant. I love digital data storage and have been perfectly happy with digital audio for music since the early 1980’s. However, the fact that cell phone users don’t even insist on full duplex communications capability from their crap-stick phone providers is evidence enough to me that they are not serious audiophiles of any sort. If you don’t know the difference between half and full duplex, I particularly like this comment and response for an answer: “GSM operates in duplex (separate frequencies for transmit and receive), the mobile station does not transmit and receive at the same time. That's called half-duplex. It's done to save bandwidth and battery power, and to make cell phone conversations more difficult.” While I’m sure the real reason cell phone providers don’t deliver full duplex is because it would be technically slightly more demanding and marginally more expensive, I’m entertained by the assumption that “it's done to . . . make cell phone conversations more difficult.” No matter why it’s done, it sure as hell makes conversations more difficult, less convenient, less entertaining, less personal, and less pleasant.

This afternoon, I tried to have a conversation with my brother who lives in Phoenix and this statement from that Atlantic Magazine article on why people hate phone calls rang true, “On the infrastructural level, mobile phones operate on cellular networks, which route calls between between transceivers distributed across a service area. These networks are wireless, obviously, which means that signal strength, traffic, and interference can make calls difficult or impossible. Together, these factors have made phone calls synonymous with unreliability. Failures to connect, weak signals that staccato sentences into bursts of signal and silence, and the frequency of dropped calls all help us find excuses not to initiate or accept a phone call.”

It’s not just “weak signals” that are the problem. Grossly misnamed “communications companies” have jammed so much data into so little bandwidth that signal strength is just one of many factors that creates an incoherent telephone call. My brother, for example, said he had “five bars” of signal strength, but our conversation was mostly a collection of Mr. Roboto vocoder noises, weird electronic bird song tweeting and screeches, and long pauses where neither of us were able to get anything across the satellite signal path. After a bit, we gave up and went back to email to carry on our “conversation.”  A few moments later, my daughter called. We both have “land line” phone systems; hers is provided by her telephone company and mine is through the internet and an Ooma Telo system. We had a pleasant 1/2 hour conversation; with each of us laughing at the other’s jokes and stories made even more personal by being able to hear the laughter while we continued the stories. No weird noises, no Auto-Tuned Kayne West sound effects, no forced pauses waiting for the phone system to reboot itself and reconnect us; just a normal telephone conversation. The kind we used to have every time we picked up a telephone that was wired to the fuckin’ wall; 75 years ago.

The fact that the quality of telephone data transmission is lousy allows cell phone manufacturers to dumb-down the whole signal path. The microphones, the “speaker,” and the analog electronics connecting those transducers to the crappy data transmission system are all degraded. Why connected a decent micro-condenser microphone to an 8bit/8kHz sample rate, 200-3.2kHz bandwidth, 64kbs data compression system? It doesn’t make sense to waste a decent transducer on a crappy ADC system. Likewise, at the receiving end why connect a half-decent speaker to a low-fidelity DAC? So, they don’t. You clearly don’t notice or care. Some of you low-life weirdoes even listen to music on your phone, out of that godawful speaker!

Cell phones have rendered over-the-wire conversations pointless and painful. They are helping us all grow apart. “Can you hear me now?” is not a question of coverage and hasn’t been for at least a decade. Now, it’s a question of did you understand that simple question through the hash of garbled transmission, Star Bores sound effects, and cut-out segments of the phrase? I’ve said this before, “I can, in a few moments, tell if a caller is on a cellphone because the quality is miserable. Always. My guess is if you can tolerate that level of distortion in a voice conversation you aren’t that discerning in any aspect of audio. So, while I’m not surprised that music is being listened to on actual speakers by an audience of 12%-and-shrinking I’m also not impressed by your musical tastes. Your opinion of audio quality is just going to make me laugh, so don’t waste either of our time.” It’s still true, but now I also don’t think you care much about communicating with your fellow human beings.

You embarassed me into installing an Ooma system. I forgot what a telephone conversation was like until I had this system.

One of the things I learned in audio equipment is that we get "trained" by the stuff we work with and listen to. After a few years using a cell phone, I'd doubt anyone's ability to make critical decisions regarding any sort of audio.

Wirebender Audio Rants

Over the dozen years I taught audio engineering at Musictech College and McNally Smith College of Music, I accumulated a lot of material that might be useful to all sorts of budding audio techs and musicians. This site will include comments and questions about professional audio standards, practices, and equipment. I will add occasional product reviews with as many objective and irrational opinions as possible.
