The speakers are pointing directly ahead.Perhaps it can also be mitigated by placing the center speaker higher or removing the glass table. This one is easily corrected by the receiver.Fortunately, I discovered that moving the seating 1 foot forwards reduced the suckout substantially. Moving the speakers didn't seem to do anything. Assuming the speakers are wired correctly with respect to phase, the only thing to do is experiment with varying the speaker and listening positions. Room equalization can't do anything about it because it's presumably at a sound pressure null, and increasing amplifier power at that frequency band will only have minimal to no effect. A major suckout is much more worrying.You can test if your receiver's auto-eq will attenuate that 40 Hz mode: surprisingly, mine doesn't seem to do anything, see below. Most receivers have automatic room equalization built in. However, I believe that tangential modes are half as loud as (equivalent) axial modes. Perhaps that's what responsible for the 40 Hz hump.
bouncing the sound waves off 4 walls instead of 2 parallel walls, there is a 41 Hz tangential fundamental mode that engages the full width, i.e. Doesn't coincide with 40 Hz.Ĥ1 Hz tangential mode for width 34ft and length 15ft There is a partial wall at 20.5 ft: if I use that, f1 = 28 Hz and f3 = 83 Hz. If I take the maximum width at 34 ft, f1 = 17 Hz, f3 = 50 Hz. It's not even clear what the room width is in my case because the left side is an open area. (45 Hz is 1130 ft/sec (speed of sound) divided by 2 * 12.5 ft.) Length at 15ft means f1 = 38 Hz. Dark = high sound pressure.Ĭeiling height at 12.5ft means f1 = 45 Hz because room height would be half a sine standing wave. Here is an example:įundamental frequency standing wave representation. There is a good Room Eigenmodes calculator and sound pressure visualizer at.

This post documents how to get it all up and running on a Mac.
– the version you can download from is version 1.0.2 and only compatible with OSX 10.4 and newer the older version 1.0.Would you like to know if your speakers are placed poorly in your room? Are there room resonance interactions you can avoid? If so, Room EQ Wizard, known as REW, is a incredibly useful and free program written by John Mulcahy for room analysis. in OSX 10.6 Soundfly appears to only work with SoundFlower 1.2.1 not with the newer SoundFlower 1.5) – make sure you use the version of SoundFlower that came with the Soundly installer, newer versions of SoundFlower may or may not work with SoundFly (e.g. – pressing the ALT-key on your keyboard while starting up Soundfly will give you extra settings options
Or maybe, one of these suggestions will help : –> gray bar at bottom –> contact (french and english)
You could contact the developer and see if he can help : It’s been a while since I installed and used Soundfly myself, so I’m not completely sure about the compatibility with the latest versions of OSX and macOS. Sorry to hear this doesn’t work for you yet.
