    Just got 4 real traps, Barely hear the difference?

    2x2 Minitraps. Strapped across 3 wall to wall to ceiling corners, can't hear a difference at all between them and my auralex. I won't be able to test it again until saturday. What's up with this? Am I just putting it in the wrong place?

    I just used various things to prop them up since I'm leaving for a wedding tomorrow morning, and I'll be back saturday.

    I really am not hearing it. I thought maybe I did as I was playing Zodiac shit by Flying Lotus but I took them back down and didn't really notice anything.

    Is the problem that I'm playing mixes that already translate and I need to play some of my own stuff?

    Also the auralex is still behind them.

    be methodical on saturday

    try placement of each trap in the mid portion of each vertical corner at the front and then place one in the mid portion of the short wall ceiling interface. Do the same along the back wall too.

    then adjust each trap (one at time) until you can notice a difference. Remember to use a test tone that is as close to the resonant frequency of each of the tangential modes - maybe use the signal generator in pro tools at -40dBfs to generate sine wave at the required freqs

    if you send me the room measurements (again I think) I can do the math for each mode or you could go to amroc - the room mode calculator make sure you select feet before entering your measurements. It will also generate a tone for each mode. There are three heights given for modes. You want to look at the ones that are 2/3 the height of the biggest. You will see the correct mode selected by looking at the room model (where it shows the pressure zones for each mode in Blue and Red).

    Any questions just ask

    I guess I'll get a second person to help adjust on the fly without being in front of the speakers.

    Would there be any particular reason I couldn't hear a difference that I should keep in mind?

    Also, is filtered pink noise generally frowned upon as a test? I was having a hard time finding bass build ups in my room with it.

    Edit: I'm getting concerned about my own hearing. I was just watching an interview with Drake's Producer who said the song Headline's was compressed, squashed, and distorted to all hell.

    I pulled up the song on my monitors and...Couldn't really tell at all. I could tell that there aren't really dynamics to that song, but I didn't notice any big, noticeable distortion. I'm concerned maybe I need to deep clean my ears or something.

    pink noise is usually used to balance your system and set overall levels (never filter it imo)

    that drake track is compressed heavily and distorted (but it is subtle, the distortion that is) - to someone who worked on it would be obvious as, less so to mere mortals and causal listeners who are listening to compromised formats (mp3/mp4/aac/etc) through design compromised earbuds/headphones

    as for why you might not hear a difference, the room modes may not be being excited by the material you are using, this is why I am suggesting sine tones at the exact frequency/pitch of the room mode

    In a sense, if I use several songs and I will only be able to hear the difference through calculated sine tone tests, doesn't that defeat the point?

    One of Winer's team told me to use room eq wizard or their filtered pink noise and my thought was "Why would I care if a program says the room is flattening out if I can't hear a difference anyway? My mixes will sound the same."

    But I'll give that sine tone a test on Saturday.

    using eq wizard is a con in my books - you are eq'ing your system to your rooms response rather than treating your room - sure it will let you do mixes that are flat in terms of an ideal response but at what cost to your perception of phase and stereo coherence?

    the thing with treatment is that it gets incredibly tricky in small rooms to notice a difference unless the room modes are going to be excited by normal program material.

    that said, notes that are within 1 quarter tone of the mode may still cause some resonance to build - it is the continuation of reflections/reverberation in this frequency range that are the reasons to put bass traps and other broad band absorbers in your room
