Question about WMA with minimum acceptable bit-rate
Hi:
Lets say I have WMA file that is monoaural and 44.1 khz and contains a song. What would be the minimum bit-rate neccesary in order for the song to be recognizable to the ear of the average human who has listened to the song before and knows the song? Thanks, Radium |

It would probably depend on the song. "Happy Birthday" performed on a cheap keyboard with no accompanyment would be recognizable at a lower bit rate than, say, Mahler's 8th Symphony. Why do you want to do this anyway? It becomes unlistenable long before it becomes unrecognizable. //Walt |

Real scientists don't ask dozens of insane questions on the interweb. They do their own work. Windows Media Encoder (and several other resources) were all suggested to you. They don't even cost anything. What is your problem? |

Which, in the past, you have made a habit out of either ignoring outright or confabulating into such blithering nonsense as to render it essentially useless. Where's the use in that? How "scientific" is that? You have also made a career out of spatting ill-founded personal opinions as "fact." Your ongoing declarations about how FM synthesis is the best or worst or whatever is notable not only for its frequency and poor factual basis, but its complete uselessness. No one, absolutely no one gives a ****. |

All your questions have been answered multiple times, but you appear to have learned nothing from them. Consider how discouraging this to people trying to provide the input. |

Whats the lowest you could go with the song "Boulevard of Broken Dreams" by Green-Day? |

This isn't really a question about bit-rate. It's about the minimum information required to recognise a song. Try http://www.songtapper.com/s/tappingmain.bin?dotap=1 You might find one bit sufficient. |

Sort of like Wikipedia, only for sound. Anyway, I tried tapping in "Happy Birthday" to see if it recognized it, and got these results: I Am A Transexual Rod Conners Happy Birthday Unknown I Wanna **** Aaron Carter Lexi Henning Aaron Slaney Is Homosexual Chas N' Dave Cool, huh? //Walt PS Did you know that the population of Elephants has increased by a factor of three? |

This isn't really a question about bit-rate. It's about the minimum information required to recognise a song. Try http://www.songtapper.com/s/tappingmain.bin?dotap=1 You might find one bit sufficient. I tried tapping in the following: J. S. Bach, Tocatta and Fugue in d J. S. Bach, Inventio #8 in F Francois Couperin le Grande, La Favorite Jan Pieterszoon Sweelink, Unter de Linden Grunde, also Meine Junges Lieben hast ein Ende and it didn't find a single one of them! So it REALLY sucks! :-) :-) :-) (but it will reconize them now :-) And, the question for our radium: if I were to play you a completely uncompressed rendition of, oh, Unter de Linden grunde, would you recognize it? |

Question about WMA with minimum acceptable bit-rate
Hello,
20kbps seems to be good. WMA performs good compared to Mp3 at lower birates.. but, not below 23-20kbps. -Raghu (www.soundzgood.blogspot.com) Radium wrote: Hi: Lets say I have WMA file that is monoaural and 44.1 khz and contains a song.

Ya like listening to 4 bit encoding? //Walt |

Then you have clearly wandered off into the field of magic and have left technology behind. Perhaps you should move your discussion to a newsgroup where they discuss magic. Do you truly not understand why this isn't possible, or are you trolling us? |

Question about WMA with minimum acceptable bit-rate
I understand that, I missed to mention that details.
Encoding at 20Kbps can happen only with 22 or 32 KHz sampling. Thanks for asking more info. Regards, RAGHU (www.soundzgood.blogspot.com) Radium wrote: RAGHU wrote: 20kbps seems to be good.
