    Hi all,

    First I'd like to say that as someone fresh out of school that is just starting in the industry, being able to work an event like this has been such a valuable experience. The level of passion and craftsmanship you all have brought to the SDC the last two years I've been with PE is truly inspiring for me. I enjoyed talking to those of you that I met, and I was blown away by the quality of all of your projects.

    In terms of the music, I'll clear some things up. We were NOT playing MP3s! One of the judges provided us with WAV files already cut down to exactly what he wanted for judging, and these files were not modified at all. This included Pines of Rome and a couple of others. The rest of the files played were CD rips ( 44.1k, 16 bit FLAC files ). We did not use VLC, nor did we use the internal sound card of the laptop. We used the USB DAC functionality of our Emotiva preamp.

    Unfortunately, those awkward transitions only started to occur once we got up there with the specific setup, and were not audible when we were testing it in the office. As you can imagine, there was little time to change the setup once we got started with the event, so I'm sorry that the transitions were so awkward. The decision to not use CDs this year was an effort to simplify the setup process after a couple of hiccups last year, but now we can view it as an experiment and probably will be going back to CDs next year.

        Jason not directing this at you, but this topic has been beat to death. i go to 3 other DIY events in the midwest, PE is the only event that continues to have problems of this nature. go back through the previous MWAF events post and read up. i really do not understand what the issue is with putting together 3 minutes of music, for 4 categories of speakers could be ??? maybe this will help.

        1. the new building, which was an improvement, is literally 1 minute from PE. someone take the equipment over the day before the event and play all the demo music. play it several times to make sure everything works.

        2. the music, this is very simple, put it on anything other than a computer.

        3. when playing demo music you need to have a few seconds between each song. going from one song right into another short circuits your brain. your brain needs a few seconds to reset for the music change.

        4. someone needs to learn how to level match music. Stimela was several db down compared to the rest of the music.

        5. get a legit cd player, server, preamp and amp. for an event like this, go purchase some nice used equipment.

        6. Ask for some help when creating the demo cd.

          What made me think it was VLC was that you stated it as at 106% of output when running the Eggs from Meredith. I know VLC allows that, but don't know if others do. I also know how glitchy it can be. I was not trying to be offensive, just stating how I thought the system ran. The MP3 mention of mine was also related to the glitchy performance. The music did seem more open and airy than MP3s can sound.

          For whatever it's worth, I didn't really dislike the cuts this year. I felt they were appropriate, and told me what I needed to know about a pair. I felt the levels were fine. The one that was quieter in the last group built up and got louder for a dynamic change, and that was a good indication of certain things.

          I'm glad for a return of a concrete media to ensure proper operation of music in the future. The computer was the source last year as well, IIRC.
          Thank you for running the sound and knowing what you were doing. I did have a great time,

            Thanks Craig. I edited my post 1 & 2 above with pics and placement info, but the info did not seem to take on post 1 (or maybe there is a delay of some type). I will wait a little while and see if the edit comes through. Let me know if you can see it.

              How was the new venu? ...and did it survive Merediths entry?

              TomZ
              Your welcome! I agree with John that the new venue seemed neutral. I was sitting on the edge of the third row. I always sit on the edge so I can jump up quick to take pictures, but this places me well off center. The ceiling had white, 2x4 foot suspended acoustical tiles with alternating 2x4 foot florescent lighting fixtures. The suspended ceiling was 11.5 feet high. PE had rolled out a thin carpet over the entire floor, so ceiling to floor reflections were well controlled. Overall dimensions of the room were about 50 feet wide by 80 feet deep with a slightly smaller interior area sectioned off with 7 or 8 foot high black drapes. It did not seem boomy at all. The back of the room outside the draped off area had several tables set up for eating, displays, and a huge Wright Brothers flying demo. The flying demo was a blast; I enjoyed watching someone else give it a go, but I did not try it. (it was really loud).

              Merediths entry was a lot of fun, as usual. And it sounded fairly good, except that the giant woofer diaphragm had a nasty sympathetic vibration resonance at about 80Hz or so. Each time the music hit this frequency, the loud buzz sent the crowd into laughter. Here are a few pics. It was really cool.

                My 3rd place Dayton edit still has not appeared. So here is the data again for the Dayton group:

                1st place: SP37 "RSX" by Chris B.
                2nd place: SP39 "C-Cake" by John H.
                3rd place: SP14 "Troy-Maple Notes" by Barrett N.

                Meredith"s entry was called "Easter Eggs w/
                Big Woofer"

                  Thank you Bill for the pics on that. Wild!

                  Like Paul, I also had a post up there flagged for spam as well this morning. I'll just paste it here as I copied it since it was longish...

                  Not meant to be a complaint in any way to PE, just thinking of ways to make things better/easier for PE staff...

                  __________________________________________________ ___________________

                  Regarding the Audio Issues...

                  Just thinking out loud... I wonder -- since there always seem to be some issues with the music -- if we could take care of that for PE for next year so they don't have to worry about it. They are undoubtedly slammed with things to do approaching the MWAF... it might really help them out.

                  Use the tunes from the tracks the judges pick from... find the best recordings of those tracks and make one nice, in/out faded, volume-corrected track for each category. Get several folks from PETT who know how to do this stuff to generate them, and make a CD to send to PE a few weeks before the MWAF so they can vet it. Maybe have track 1 be a pink noise track at the same relative volume as the rest of the tracks to make life easy...

                  SAMPLE TRACK LIST:

                  1: Pink Noise
                  2: Open Unlimited Track--(3 approx. 1 minute song snippets)
                  3: Dayton Audio Track--(3 approx. 1 minute song snippets)
                  4: Under $200 Track--(3 approx. 1 minute song snippets)
                  5: Over $200 Track--(3 approx. 1 minute song snippets)
                  6: A couple of fun tunes for the "Fan Favorite" speaker to jam out to.

                  I know there are some of us that could do this easy enough. It's a HUGE part of the competition, but it seems to be very hard to get right, maybe we could help out?
                  Watcha think?

                    Here are some pics of other speakers, taken at random from my collection:

                    SP 15 "Zingers by Ben S. (Wolf) (I agree, the highs sounded much better with the 6th part, much smoother than Indy)

                    SP 41 "RMLS 16x2" by Ethan B.
                    SP 29 "Titans" by Eric W.
                    SP 38 " Safaris" by Chris B (dynamo)

                          A big thank you to Parts Express for putting on another great show. Enjoyed discussing speakers with the experts, listening to all the new creations, snapping tons of photos, eating pizza and hotdogs, browing the swap meet, etc, etc. I could not believe the large number of excellent door prizes that were being given out this year. Seemed like much more than prior years. And a free pair of the RST28F-4 tweeters to boot.

                            Meredith's speaker should win in the most unique category as I don't think anyone has seen anything like that. I couldn't even imagine putting the tweeter into that stuff bird on branch stands. Its always fun and exciting to see a design that is totally different from the norm.

                              Thanks, Chris! It was good to finally meet you as well. And congrats on your first place finish with your RSX speakers. I wish I could have heard them, but I left early for lunch and missed the Dayton session completely. (I needed more time to rummage through all the old tube junk at the swap meet.) I bet they sounded very good. I took several close up photos of your coaxial tweeter mount; looks very professional.
