There is an app called " tune in" that integrates with Apple car play and android auto that will allow you to stream most am stations at better quality than if you received them over the air...the app also has a built in tuner if you want fm digital or am stations the old fashioned OTA way
Not correct on some of the above statement. .
1) Quality of streaming depends JUST LIKE OVER THE AIR on how much attention is paid to HOW the sound is delivered to the carrier. If a "raw" sound was sent from the control room, there would be no AGC (automatic gain control) for leveling the audio, nor any other processing that gives you what you "expect" from your loca station. In our case, at WION you DO hear exactly what is on the air, as we send our AM STEREO product from a tuner in my office into a sound card, encoded, and sent to Live 365, which then distributes it to others like Tune-In Radio.
2) Their "tuner" to which you refer is really NOT a tuner. No "app" you download can magically create a real tuner that uses the AM and FM airwaves directly. For a tuner to be "real" it has to have an antenna to match the frequencies you wish to
tune and the circuitry to TUNE AM and FM. The only thing Tune-In does is perhaps LOOK like a tuner and let you set favorites. You are simply selecting a digitally streamed feed from a station that LOOKS like the old-fashioned way. It's just to appease looks. An AM tuner needs AM capability. No tablet, phone, or device you use tune-in on unless it's a combined WEB AND AM/FM DEVICE can do that. There would need to be physical circuits and selectors for that to happen.
2a) Tune-in builds on broadcasters' work by re-transmitting our streams and inserting THEIR commercials, quite a few at startup. Annoying to say the least, and...when a broadcaster chooses a certain plan, those commercals can come at ANY time in the listening stream, not when the station takes it's own natural breaks, losing you continuity of content, and losing the station listeners. Stations who opt to NOT have commercials inserted pay a higher rate for streaming than those who allow the "third party" spots. It's why we had a skill developed for Amazon that is for our station only, and why we opt for the "no inserting commercials" in our monthly package.
3) Finally and most importantly: Streaming costs stations MONEY. Streaming is NOT available everywhere and cannot subsitute for an over the air signal in many places in the USA. Here, in Michigan, along I-96, there are places between Lansing and Detroit where even Verizon's signal drops, and you cannot access digital information which is needed to assemble any stream. It is NO substitute, and should not be considered in the same league as an "over the air" signal. If this is used as a crutch for pulling AM from dashboards then, the damn companies that pull us OUT of their dash can start paying my music licensing and bandwidth fees to provide this "free" service to you, the listener. Period. It's a shifting of cost to even PROPOSE that streaming is a substitute for free radio in a car, and that cost gets shifted to your BROADCASTER.
