Volume Level of "Tuner" vs that of "CD" "Tape" or "Phono" on my homestereo, boombox, or car receiver
It's the same wherever I go. In the car, I switch from my mp3 jack or
CD to a FM station and instinctively I have to turn the volume down by at least 1/3rd. At home, switching from a record, CD or tape to the radio - gotta crank that volume down! Ditto at the beach on my boombox. Now folks I don't need a lecture on dyamic compression/sonic maximizers and all the other crap radio stations reem their music through. I can even duplicate the effect quite faithfully(or hideously for you audiophiles reading this) with the rudimentary compressor in Audacity. What I would like to know is if anyone here knows if any compression or limiting exists in the circuits of the Tuner sections of the aformentioned audio equipment above - especially in consumer electronics mfgd more recently? Because I really don't believe that radio stations' own processing is solely to blame for my having to crank UP the volume when going from AM/FM a CD or mp3 or cranking DOWN the volume after switchng from CD/ mp3/phono AM/FM. 1. Does the tuner section on consumer stereo equipment/portables/auto sound incorporate some compression/limiting circuitry? 2. Is the tuner input level set intentionally louder than the line inputs(CD, aux/mp3, etc)? 3. Or, is it a combination of 1 and 2, on top of compression/other processing employed by the radio stations? much appreeesh, -ChrisCoaster |

Not to worry, the FM stations will get new equipment real soon and address that so that they can come closer to an aspect ratio of zero or less. At home, switching from a record, CD or tape to the radio - gotta crank that volume down! Ditto at the beach on my boombox. At home perhaps you can try get away with installing an attenuator in the 4 to 6 dB range inside the contraption, but I wouldn't even consider trying with a car radio, those likely have their innards compressed to a negative aspect ratio and you will not bee able to make them fit the case if you open it. Because I really don't believe that radio stations' own processing is solely to blame for my having to crank UP the volume when going from AM/FM a CD or mp3 or cranking DOWN the volume after switchng from CD/ mp3/phono AM/FM. Very many years ago some design contained sensitivity trimmers to make the phono input match FM, my Beomaster 3000 was like that, including balance-matching via nulling of inversed channel 1. Does the tuner section on consumer stereo equipment/portables/auto sound incorporate some compression/limiting circuitry? If so it is called "night" or similar. We can not have the populace understandin this, so we call it something else. 2. Is the tuner input level set intentionally louder than the line inputs(CD, aux/mp3, etc)? 3. Or, is it a combination of 1 and 2, on top of compression/other processing employed by the radio stations? FM statios are voiding the headroom asumption for clean transmission that the tuner electronic designer made because it was in his textbook. He should have desined for 5 dB transmission malpractice. Orban is not to blame, he quite probably warn them in the manual. From the sound of some of the louder FM's over here they first max the 5 band, then hit a multiband clipper and then push it well into the tranmitters protection limiter. All have hideously audbible compression artifacts that stand out obnoxiously on even the poorest possible playback equipment but can become impressively loud on a JCV loudenboomer hung on a warehouse wall with volume set to 11 and beyond. And thus the FM stations aim is well and truly met, because THAT is what they aim for. much appreeesh, I must have some kind of mind damage from working with printing machines for so many years, I tend to solve the problem by turning the car radio off and just listening to the car. Perhaps I should resume my venture into avant-garde techno ... a computer harddrive died during a file-shuffle with all my music on it back in 1997, and I just haven't bothered to retrace ... was in a large rythmical structure being built to support ephemerial synths when it happened. I made a "In C" rendition in DeLuxe music on my Amiga, I had it as midi dump, but now only the DAT tape of the Amiga sound systems performance of it remains .... -ChrisCoaster Kind regards Peter Larsen |

When your boombox was designed they probably set it as near equal as they could. Since then relative loudnesses of the media have changed, and that is what you are hearing. If you have any technical savvy, you could perhaps get inside the box and adjust everything to level it back up. At home, switching from a record, CD or tape to the radio - gotta crank that volume down! Ditto at the beach on my boombox. You can **** off with your boombox at the beach. Use headphones and stop being an inconsiderate little ****. That's the last bit of advice you are getting. d |

Actually to hear any boombox I bring to the beach you would actually have to occupy my blanket. I've got the low-end EQ turned up and the 4k notched down about -4dB - just like a Fletcher Munson Curve. Or if it's my later model, I set the bass boost to max and LOWER the volume! At least I know when to use LF boosting circuits. LOL. The only reason I may need to turn my box up a little is to mask Tito 60 feet away in the parking lot with the kickers in his Pathfinder cranked up to 11! LOL -ChrisCoaster |

And that is on a logrithmic volume control. The actual difference is even more. At home, switching from a record, CD or tape to the radio - gotta crank that volume down! Ditto at the beach on my boombox. Make up some hypercompressed CDs, and play those. Now folks I don't need a lecture on dyamic compression/sonic maximizers and all the other crap radio stations reem their music through. I can even duplicate the effect quite faithfully(or hideously for you audiophiles reading this) with the rudimentary compressor in Audacity. Then do it! What I would like to know is if anyone here knows if any compression or limiting exists in the circuits of the Tuner sections of the aformentioned audio equipment above - especially in consumer electronics mfgd more recently? In another post Scott and I told you that there are no such things, and you promptly ignored us. On consideration, There are FM radios with "midnight swtiches", that do introduce compression. Some FM radios also have a kind of opposite compression circuits, in the form of noise reduction circuits, one of which is called "DNR". I'm not going to repeat my objections to the rest of your post's points, because I really don't like being snubbed in public. |

Just play modern CD's then, it's *impossible* to compress them any more than they already are! Depends which ones. There are still some well-made audio CDs being made and sold. I don't even know that the majority of all new audio CDs are hypercompressed. It could well be just an objectionable minority. |

It could well be just an objectionable minority. OK, I'll be more specific, it's the VAST majority of pop, hip-hop, rap CD's and a very large percentage of country etc. these days. But yes it's a bit less for jazz, and definitely less for classical. Trevor. |
