Is it live or is it Memorex? - Recorded Realism
One goal of music recording is to capture a true sound, so when played back
it sounds like the musicians are right there in the room with you. The experiment shown in my newest video proves it's not an easy task! We weren't entirely successful, but did manage to get fairly close with some of the instruments.

Guys,
You've got it backwards -- so that you are in the original acoustic space. Yes, that too, but it's a different goal. I think you need a surround setup for that to be convincing. as Michael Flanders said, "I can think of nothing I should hate more than to have a symphony orchestra actually playing in my sitting room." Agreed fully. Funny side story: When I was doing the opening monologue I said "string quartet or rock band" and also said "orchestra." When I edited the video I realized an orchestra is NOT something you want in your living room! So I took out that part. :-) Thanks guys. --Ethan |

The cello was fairly convincing IMHO. I didn't find the percussion very "realistic", though. Daniel |

As done, it eliminates essentially all the variables except the loudspeaker. The Mackie HR624 exhibits a symptom of inaccuracy found in many monitors. The 24 dB/octave slopes of the crossover are introducing Electrical Phase Distortion, yielding a somewhat "pinched" sound in the 3 KHz crossover region. A monitor with gentler crossover slopes will sound more accurate. For any analog EQ, "a slope greater than 6 dB/octave introduces EPD that is noticeable and irreversible". -- ~ ~ Roy "If you notice the sound, it's wrong!" |

The 24 dB/octave slopes of the crossover are introducing Electrical Phase Distortion, yielding a somewhat "pinched" sound in the 3 KHz crossover region. A monitor with gentler crossover slopes will sound more accurate. Not necessarily, on several counts. First, one purpose of higher-order crossovers is to lessen the area of overlap, where both drivers are contributing to the sound. Having more overlap, as you have with gentler slopes, runs the risk of: Having both drivers operating, but with very different dispersion patterns. Generating acoustical phase distortion because the two drivers are not located at the same point in space. Another purpose of higher-order distortion is to roll off the signals rapidly enough to stay away from troublesome areas. With a gentler slope, you run the risk of putting significant signal in at the frequencies of cone breakup (woofer) or fundamental resonance (tweeter). There isn't one best answer, unfortunately; 6dB/octave crossovers have strengths and weaknesses, as do higher-order crossovers. I've heard genuinely excellent and accurate sound with all kinds of crossovers. Sometimes I think it depends more on the designer's skill than the particular engineering solution chosen. And by the way, the "pinched" sound at the crossover frequency of the Mackie could also be coming from cone breakup, distortion in the tweeter, horn effects in the tweeter, or other driver problems rather than the crossover. Peace, Paul |

A room might be able to provide the correct reverberation for a string quartet -- but if it did, it would badly color the sound that playback of other types of music would be unacceptable. |

Oh, I dunno -- I've done the "bring 'em to your room" type of recording with folk groups, jazz trios, and other small ensembles. (Basically recording in a fairly dead acoustic, letting the listener's room provide the setting.) I agree with you (and Mr. Flanders) that it's not an appropriate approach for an orchestra.

Daniel,
Ethan, the video editing is terrible.. ;-)) No kidding. I edited based on the audio and let the video do what it will. If only I hadn't moved my arms so much it'd be much less obvious. But the edits removed some extra parts that were unnecessary and would have been distracting. --Ethan |

I would say that inaccuracy in that speaker was a second order effect compared to that of the room. Ethan had surrounded the setup with gobos, but they didn't extend full height and that would certainly have some effect. It was certainly a very interesting test though. d |

Look for Recorded Realism near the bottom of the RealTraps Videos page: http://www.realtraps.com/videos.htm I was really surprised how well the cello worked (for me). Some of the little shakers came off far worse (for me). Very interesting indeed! But for a really surprising recording, catch the sound on "How to Set Up and Treat a Listening Room". Not to spoil the surprise, but near the end it's revealed that sound is from the on-camera mic. Now, *that's* room treatment. Much thanks, as always, Chris Hornbeck |

Certainly not if you try to reproduce the sound levels they'd produce if you squished them into my front room. They're loud in a big concert hall or a school hall or a theatre - especially if you're close to them. I still remember my first rehearsal with one in a rented school hall. Flanders and Swann were good though. "Then you'd only get the true sterephonic effect if you sat in the cupboard" or something to that effect. - Richard |

Daniel,
In fact I was just kiddin'... ;-) Whew! :-) What about the single 4033 then? I have a pair of 4033s but I figured Stereo would just confuse the issue, especially on the larger instruments like acoustic guitar and cello when compared to the small Mackie speaker. --Ethan |

Roy,
Whatever its source, Mr. Winer has plainly demonstrated that the Mackie HR624 is not sufficiently accurate for pro applications. I agree with Don that the room dominates. In every case you are hearing the Mackie through the 4033 five feet away, not the DPA close up. More to the point, Mackie HR speakers are likely the flattest speakers available at reasonable prices. If you have access to Philip Newell's Book "Recording Studio Design" take a look at Appendix 2. There are 36 popular "pro" monitors compared for frequency response, ringing, distortion, etc and the Mackie (824) is among the flattest. Much flatter than some currently popular models including some that are very expensive. The Mackie's distortion is also about the lowest in the bunch. --Ethan |

Why didn't you tilt the Mackie speaker so the mic was on its tweeter axis? I think that would have given it a better chance of doing a good job. d |

The added "room" from the DPA is close to negligible. What I hear is Electrical Phase Distortion, not "just a tonal balance variation of the sort that could be fixed with eq" The contribution is there and will result in adjustments in a mix that should not be made. A better form of loudspeaker evaluation protocol uses recorded program material. The playback via a monitor and mic is compared to a direct feed of the playback. For this, care must be taken to minimize influence from the room. Another method is to suspend the test mic above the test monitor lying on its back in an open field. After comparing numerous monitors, it is easy to discern the more accurate ones from the others. I stand on my comment about the Mackie HR624. -- ~ ~ Roy "If you notice the sound, it's wrong!" |

Overall, I thought the Mackie sounded "thin" compared to the live. Even with the wood sticks, you can hear a mid tone that is missing from the Mackie up until you hit them together hard at the end at which point that mid tone comes out. I thought the acoustic guitar was totally different sounding through the Mackie. The electric guitar was reasonable. The cello sounded very good up until the point where you were hitting multiple strings and then there was some oddness going on. Maybe the speaker was overloading? I happen to like the Mackie monitors BTW. I was using Event ASP8 for this though and played a low levels. Interesting experiment! |

I think that would have given it a better chance of doing a good job. The microphone was directly on-axis. Perhaps it's not clear in the video given the angle of the camera looking down, but I definitely thought of that and set the microphone height accordingly. The microphone was also pointed straight at the Mackie speaker. --Ethan |

Thanks John. To my ears the cello sounds pretty close but lacks deep bass.
I'm sure the loss of bass was due to that particular close microphone placement. --Ethan "John Connors" wrote: General commentary... Overall, I thought the Mackie sounded "thin" compared to the live.
