Stereophonic to Octophonic
Hi all,
Thanks so much for your recent advice regarding static/crackle reduction on old time radio mp3s. I've downloaded trial versions of the programs several of you suggested and have managed to clean up the audio somewhat; though there is a reason that 'garbage in, garbage out' is a truism. So now I have another query which I'm hoping you can help me with: I need to create both a stereophonic/two-channel and an octophonic/ eight-channel version of the project I'm working on. I know it would be easier to mix down the octaphonic version into the stereo version, but unfortunately I have to do it the other way around. I'm wondering if there's a program (for PC preferably) out there somewhere that can take a stereo file and translate that into eight mono tracks/four stereo tracks. Is this just wishful thinking? Are there any programs/strategies that you might suggest for this? Thanks again! -Sarah |

Stereophonic to Octophonic
I need to create both a stereophonic/two-channel and an octophonic/
eight-channel version of the project I'm working on. I know it would be easier to mix down the octaphonic version into the stereo version, but unfortunately I have to do it the other way around. I'm wondering if there's a program (for PC preferably) out there somewhere that can take a stereo file and translate that into eight mono tracks/four stereo tracks. Is this just wishful thinking? Yes. This is, in principle, impossible. However, one of the Blu-rays for a Disney (?) film discusses the use of software that can generate tracks isolating specific instruments. I don't remember the name of the software (if it was mentioned), or where it could be obtained. |

What do you want the octophonic version to sound like? Instruments
surrounding you (quite hard)? Instruments in front, hall ambience surrounding you (not as hard)? Peace, Paul |

Are there any programs/strategies that you might suggest for this? Duplicate mixdowns. I do no see any possible circumvention becuase ambience-effects, be it emulated natural or intentionally artificial, needs to be deployed very differently. Thanks again! You can not unmash potatoes. -Sarah Kind regards Peter Larsen |

Wishful thinking. Also wishful thinking that you can make such an "un-mix" without hearing what you're doing. But if you have a multitrack recorder or a computer audio interface with 8 outputs and you have 8 speakers, you probably already have a program that will let you send your tracks to 8 discrete outputs. -- "Today's production equipment is IT based and cannot be operated without a passing knowledge of computing, although it seems that it can be operated without a passing knowledge of audio." - John Watkinson http://mikeriversaudio.wordpress.com - useful and interesting audio stuff |

Thanks so much for your recent advice regarding static/crackle reduction on old time radio mp3s. I've downloaded trial versions of the programs several of you suggested and have managed to clean up the audio somewhat; though there is a reason that 'garbage in, garbage out' is a truism. MP3 encoding basically ruins waveform shapes and makes further post-processing impossible or at least very difficult. Lossy compression is only for use for release formats that will never encounter any additional processing (and that includes equalization). Unfortunately such a thing does not happen. So now I have another query which I'm hoping you can help me with: I need to create both a stereophonic/two-channel and an octophonic/ eight-channel version of the project I'm working on.

Sure, you can just pan the left channel to one of the eight and the right channel to another one of the eight, and leave the other six unused. There is no dishonor in not using all the channels. Stuff does not have to be coming out of all the speakers all the time. If you have automated your mix, though, it should not be all that difficult to remix it, using eight aux busses.... keep the same levels that you had for the stereo signals, just change the pans. Are there any programs/strategies that you might suggest for this? Well, your real nightmare will be eight-channel monitoring. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Thanks again! -Sarah __________________ First of all, "stereo" as we know it came to be associated with two- channels simply because of technical practicality of the age it was introduced in: post-WW2. The root of the word stereo is "solid". This implies that sound could be coming at the listener from any where from two to twenty(!!) directions. Surround was simply a marketing term to selll the concept of multichannel sound that came from directions not limited to in front of the audience. It's all really just stereo. Octophonic is simply stereo via 8-channels, preferably discrete, but can be derived from adjacent channels of a X.1 digital surround system. -CC |

Thanks again! -Sarah Hi Sarah, Can you clarify whether you need to to create the 8-channel mix _from_ the stereo mix, or whether you just need to do it after you have completed the stereo mix? If the former, you don't have many options other than panning the left channel to the odd speakers and the right channel to the evens, but if the latter (and you still have access to the multi-tracks) creating a new 8-channel mix is perfectly doable if you have a suitable monitoring environment and plenty of time. If this is for a site-specific installation or performance where you know the room and the speakers you are going to use, your solution might be relatively simple - especially if you have access to the space and equipment in time to do some experimentation. If the project is for dissemination for as yet unknown playback contexts, you'll need to worry more about the monitoring environment and the translatability of what you have created. If you can give a little more info on the context of the project though, it would be helpful. David |

Stuff does not have to be coming out of all the speakers all the time. It depends on the reason. If you're doing an exhibit installation where you want to be able to walk around an area and stand near the violins, then stand near the horns, then stand near the bases, then stand near the conductor, you need something coming out all the speakers (which may be hidden behind cardboard cutouts of the different orchestra sections).
